The Rise of Arduino Compatible Boards - An Exploration of the Expanding Ecosystem

The Genesis of an Open Source Movement When Arduino was launched in 2005, it helped spawn the age of accessible, affordable microcontroller boards and platforms. By providing a common hardware and software standard that was simple to use but still powerful, Arduino opened the door for non-engineers and electronic hobbyists to easily create interactive projects and prototypes. This drastically lowered the barrier to entry for physical computing and embedded systems. Within a few years, the Arduino platform had grown into a thriving global community with developers of all skill levels sharing code, tutorials, and ideas. The Growing Demand Inspires New Options As Arduino gained popularity and demand increased, companies recognized an opportunity to expand the ecosystem. Rather than competing directly with Arduino, many started releasing boards that were compatible with the Arduino software and libraries. These clones and derivatives allowed users to benefit from Arduino's openness while also having alternative hardware options at lower price points or with additional features. Some boards were nearly identical clones while others incorporated unique enhancements. Regardless, their compatibility with the Arduino IDE gave users the flexibility to choose a board that best fit their specific needs and budgets. A Proliferation of Board Types and Form Factors Today, the variety of Arduino Compatible boards available is staggering. In addition to the classic Uno and Nano form factors, there are boards shaped as mini PCs, single-board computers, wearables, educational kits, drones, robots, and more. Each brings something new while still maintaining the foundational principles that make Arduino great. For example, some focus on size and portability while others emphasize power, connectivity, or cost. Educational boards make learning to code more interactive and hands-on. Industrial boards enable Arduino to be used in professional contexts that require certifications or rigorous testing. A World of Enhancements Beyond the Original Spec Many Arduino compatible boards one-up the original Arduino specs by including features like WiFi, Bluetooth, GPS, high-speed microprocessors, more memory and flash storage, additional input/output pins, and specialized sensors. Some push processing power to the level of Raspberry Pi while shrinking the board size. Others add compatibility for new languages beyond just C/C++. Interfaces like Ethernet, USB, and add-on shields expand what these boards can interface with. Many also supply dev kits with components, sensors, motors and displays to simplify prototyping of specific project types. Get more insights on Arduino Compatible

TLV320DAC3100 first bops 🔊🎶💃🕺

OK, after many hours spent with Claude on writing a driver for the TLV320DAC3100 (https://www.digikey.com/en/products/detail/texas-instruments/TLV320DAC3100IRHBR/2260591), we finally have it configured using our driver, and playing an MP3 stream on this ESP32. This I2S DAC has a particularly complex PLL and audio-routing system, so it's not one where you can just pipe in I2S data and have it magically play. One nice thing we got working on is the MCLK, which is generated from the BCLK, so it'll work great with anything from an Arduino-compatible to a single-board computer like Raspberry Pi. We're hoping to get the headphone detection working next so that we can turn off the amp when the headphone is plugged in. Also, it should be able to control the volume from the headset buttons. Also, we want to get the internal beep generator going so we can make tones separate from the audio stream for UI notifications.

Sega Genesis Game Pads and the Mode Button

I had a Sega Mega Drive (aka Genesis) as a kid, and also a 6-button game pad. Actually still have, but I haven't used them in forever.

The 6-button controller has shoulder-button labeled "MODE" and I only learned what it's for recently. When you hold it down while starting the console, it will disable the extra buttons and act like an old 3-button controller. Ok, that's pretty boring. The interesting part is why I didn't need to know that.

3-Button Controller

Basically, the 6-button pad Just Works because the 3-button pad already had one button too many. The controller uses a connector with 9 pins. One pin each for power and ground leaves you with 7, but it has 8 inputs: UP, DOWN, LEFT, RIGHT, A, B, C, START.

To solve this, the controller contains a multiplexer. By setting the voltage on one of the pins, the console can select which inputs it wants the controller to report.

When voltage on the select pin is LOW, the controller indicates that it is present (so you can distinguish "no controller connected" from "no buttons pressed") and reports the state of the inputs UP, DOWN, A, START.

When voltage on the select pin is HIGH, the controller reports UP, DOWN (again), LEFT, RIGHT, B, C.

This makes it backwards-compatible with Sega's earlier console Master System, with B and C corresponding to buttons 1 and 2 on the MS controller, and A and START doing nothing.

The way a 3-button game normally interacts with the controller is that for each frame, the game briefly sets the select pin LOW, records the inputs, then sets it back to HIGH and records the rest. These are then the inputs for that frame. This is also called a pulse.

6-Button Controller

Instead of a multiplexer, the 6-button controller has a microcontroller that counts the number of pulses received. For the first two pulses, it behaves like a 3-button controller. Also, the counter resets after not receiving a pulse for 1.5 ms. That way, a 3-button game running at 60 fps that reads the controller once per frame will only see the behavior that it expects. Unfortunately, a small number of 3-button games don't behave this way (Ms Pacman for example), so that's why the MODE button is needed.

A 6-button-aware game interacts with the controller by rapidly pulsing it three times every frame. When the select pin is set LOW for the third time, a 6-button controller will indicate that it is in fact a 6-button controller. If a game isn't 6-button-aware and somehow gets the controller in this state, this looks as if you're pressing UP and DOWN simultaneously, so that's where the problems start.

When the pin is set to HIGH again, the controller reports the X, Y, Z and MODE inputs. So you can also use the MODE button as a normal game button. Only a handful of games do this though, and some of them only for cheat codes. (I actually happen to own one of them: Vectorman)

I just thought this is very hacky and also really cool! I wonder if I could manage to read out my old controllers with an Arduino or something!

Arduino-Compatible Open-Source Dual CAN-FD Network Analyzer

You can now sniff two CANFD busses with SavvyCAN and CANFDuino for less than $150! This cost-effective solution is worth noting. The configurability of the FD settings and messaging in SavvyCAN’s GVRET has not yet been fully baked in. It looks like it’s currently coded for 2 Mb CANFD speeds, which seem to be the most common combination for CANFD automotive networks.

November lately, 2023

November has been a ride so far. Here is a detailed overview of my 10 days of November:

Spend most of my days, staring at a code to incorporate a better way to store data in a text file without using an SD card or EEPROM as my arduino board doesnt have that functionality.

Tried out a minimum of 7 data storing methods with the board, only for 1 to work properly

My arduino board becomes fried

Travelled to town to purchase a new board and deliver it to school for further testing

Spent my weekends working on Printed Circuit Boards, checking on designs etc

Coded my weekends away to optimise the codes into functions and tested it with a verification app, at this point, i have added data storage, data retrieval, error handling, data clearing, averaging into the code. All worked with some bugs in place.

Attempted to incorporate with our own app and failed

After group members testing, app is only compatible with old codes and the new script cannot be used. (Illogical as the base code for new script is the exact same and had tested with the old code in this new script and app failed)

PCB board connections had issues, board cannot be powered

Tested and troubleshooted for about 5 hours straight

Found out during dinner that board was not grounded

Went back to solder a connection

Arduino board died before tests cannot be done

Another board used and PCB worked

By the end of tomorrow, this project is over. In the end, we had a working product that can do the functions we have envisioned. It is just unfortunate that my newly coded functions cannot be incorporated with the main code. But at least, it works so my efforts are not all wasted.

But yes, it has been a hectic week and it is mainly from a singular project that requires us ti come up with a product from scratch. Our device is working, and that is the important thing.

My group will be presenting on our product tomorrow morning. Wish us luck! No photos of our product as there is a chance it might be further developed in future.

Arduino Due vs. Mega: A Comprehensive Comparison

What is Arduino Due and Mega?

The Arduino platform has revolutionized the world of DIY electronics, providing hobbyists and professionals alike with versatile and powerful microcontroller boards. Among the myriad of options, the Arduino Due and Arduino Mega stand out for their advanced features and robust performance. The Arduino Due, introduced in 2012, is the first Arduino board based on a 32-bit ARM core microcontroller, the Atmel SAM3X8E. In contrast, the Arduino Mega, built around the 8-bit ATmega2560 microcontroller, is known for its abundant I/O pins and memory. Understanding the differences between these two boards can help in selecting the right one for specific projects, enhancing both functionality and efficiency.

Processing Power and Performance

The processing capabilities of the Arduino Due and Mega are distinctly different, primarily due to their core microcontrollers. The Arduino Due, with its 32-bit ARM Cortex-M3 processor running at 84 MHz, offers significantly higher processing power compared to the Arduino Mega's 8-bit ATmega2560, which operates at 16 MHz. This difference in architecture and clock speed means that the Due can handle more complex calculations and tasks faster and more efficiently than the Mega. For projects requiring high computational power, such as real-time data processing or handling multiple sensors simultaneously, the Due is the superior choice. However, for simpler tasks, the Mega's processing power may suffice.

Memory and Storage Capabilities

Memory is another critical aspect where the Arduino Due and Mega diverge. The Arduino Due is equipped with 512 KB of flash memory for code storage and 96 KB of SRAM for data. On the other hand, the Arduino Mega has 256 KB of flash memory and 8 KB of SRAM. Additionally, the Due features a Direct Memory Access (DMA) controller, which allows for efficient memory operations, freeing up the CPU to handle other tasks. These memory enhancements make the Due more suitable for applications requiring large codebases and significant data handling, such as advanced robotics or sophisticated control systems. The Mega, with its more modest memory, is ideal for less demanding applications.

Input/Output Capabilities and Expansion

Both the Arduino Due and Mega are renowned for their extensive input/output (I/O) capabilities, yet they cater to different needs. The Mega boasts a whopping 54 digital I/O pins, 16 analog inputs, and 4 UARTs, making it ideal for projects that require multiple sensors, actuators, or communication interfaces. The Due, while offering fewer digital I/O pins at 54, includes 12 analog inputs and 4 UARTs, along with additional features like two DAC outputs for analog signal generation and enhanced PWM capabilities. These features provide the Due with superior analog output capabilities, making it suitable for applications like audio processing or advanced signal generation.

Power Consumption and Compatibility

Power consumption and compatibility are practical considerations when choosing between the Arduino Due and Mega. The Due operates at 3.3V logic levels, which makes it more power-efficient than the Mega, which uses 5V logic levels. This lower voltage operation is beneficial for battery-powered projects where energy efficiency is crucial. However, the 3.3V logic also means that the Due is not directly compatible with 5V components without level shifters. The Mega, with its 5V logic, offers broader compatibility with existing Arduino shields and components, making it a versatile choice for a wide range of projects. Understanding these power and compatibility nuances can help in making an informed decision based on the project's specific requirements.

[quartz-components]

The Arduino Uno R3 is an ATmega328P microcontroller-based development board. This is widely popular in Embedded electronics because of the available resources and easy to use by everybody features. With 14 digital input/output pins where 6 can be configured and used as PWM outputs, 6 as analog inputs is a great addition for I/O related operations. Powered with a 16 MHz ceramic resonator, an USB connection, a power jack, an ICSP header, and a reset button.
