Understanding ESP32 Pin Configuration: A Developer's Guide

The ESP32 microcontroller has become a cornerstone of IoT development, thanks to its versatility and powerful features. One of the most crucial aspects of working with ESP32 is understanding its pin configuration and capabilities. Let's dive into the essential aspects of ESP32 pins that every developer should know.

GPIO Pins Overview

The ESP32 boasts up to 34 GPIO (General Purpose Input/Output) pins, but not all are available for use in most development boards. Some key points about ESP32 pins:

GPIO 6-11: Reserved for internal SPI flash connection

GPIO 34-39: Input-only pins with no internal pull-up/pull-down resistors

ADC Capabilities: Two 12-bit SAR ADCs, supporting 18 measurement channels

Touch Sensors: Up to 10 capacitive touch GPIOs

Special Function Pins

Several pins serve dual purposes or have specific functions:

Boot Mode Pins GPIO 0: Bootloader mode when pulled low during reset GPIO 2: Connected to on-board LED in many development boards

UART Pins GPIO 1 (TX) and GPIO 3 (RX): Default UART0 communication Often used for flashing and debugging

SPI Pins VSPI: GPIO 5 (CS), 18 (CLK), 19 (MISO), 23 (MOSI) HSPI: GPIO 14 (CLK), 12 (MISO), 13 (MOSI), 15 (CS)

Best Practices for Pin Usage

Strapping Pins Always check the strapping pin status before using GPIO 0, 2, 4, 5, 12, and 15. These pins may affect boot behavior if incorrectly configured.

Input-Only Pins When designing sensor interfaces, prefer GPIO 34-39 for analog inputs as they're input-only and less susceptible to noise.

Pull-up/Pull-down Configuration

ADC Usage ADC1: Can be used with Wi-Fi/Bluetooth active ADC2: Only available when Wi-Fi/Bluetooth is disabled

Common Pitfalls to Avoid

Don't use GPIO 6-11 in your projects as they're connected to the internal SPI flash.

Avoid using strapping pins for critical functions that can't be changed during boot.

Remember that GPIO 34-39 don't have internal pull-up/pull-down resistors.

Be cautious with voltage levels - ESP32 pins operate at 3.3V.

Conclusion

Understanding ESP32 pinout is fundamental for successful project development. By following these guidelines and best practices, you can avoid common issues and make the most of your ESP32's capabilities. Remember to always consult the official ESP32 technical reference manual for detailed specifications and updates.

month five. the nerds have accepted me as one of their own. (translation: the megasupercomputer guy offered me a student job next semester where i will be paid to sit around, organise cables and nerd out to anyone who comes asking for nerd shit)

i have been subtly invited and wordlessly accepted into a semisecret club of friendly nerds. we’ve got a guy who built a retractable disco ball above the ceiling tiles of his office. we’ve got a guy who has access to a 80k euro megasupercomputer that he used last night to transcribe a meme video bc he needed to find a specific clip of it.

i’m in good company.

Monty Jaggers McGraw:

I am writing new BASIC programs to demo at my VCF Southwest 2025 exhibit of my 1979 Tektronix 4054A color vector graphics computer.

One of the programs I am writing is a 1978-1979 Battlestar Galactica TV demo. That TV show had $500,000 of Tektronix vector graphics computers and test equipment and many screenshots of their green vector storage CRT displays - some stills - some animated. These computer graphics were generated on both 1975 4051 and 1976 4081 vector graphics computers - predecessors to my 4052 and 4054A computers (see first photo attached).

Miami Herald TV 1978 magazine interview with the Battlestar Galactica set designer indicated extras on the set stationed in front of the 4051 computers were playing games during filming to increase realism and were so absorbed they kept playing after the cut! (article page attached).

The 4051 and second generation 4052 were the same physical size and used the same CRT and same Display board, but the 4052 and 4054 computers replaced the 800KHz Motorola 6800 CPU with a custom four AMD2901 bit-slice CPU to create a 16-bit address and data bus ALU which emulated the 6800 opcodes and added hardware floating point opcodes to speed up these computers 10x over the Motorola 6800, doubled the BASIC ROM space to 64KB and doubled the RAM space to 64KB!

I created these vector bitmap graphics using a "3D CAD" picture I found on the web of the Battlestar Galactica (last attachment).

As far as I know - there was never any 4050 BASIC program to view bitmap pictures on any of the 4050 computers. The 1979 4014 vector graphics terminal had a grayscale bitmap mode in the Extended Graphics option board, but I have only found a couple of bitmap 4014 images on a single Tektronix demo tape cartridge.

My 4050 BASIC program to display bitmaps works on all 4050 series computers - with an optional Tektronix 4050R12 Fast Graphics/Graphics Enhancement ROM Pack. This ROM Pack speeds up displaying vector images (including vector dot images) 10x over using BASIC MOVE and DRAW commands.

The Battlestar Galactica bitmap image in R12 binary format is 332234 bytes - slightly larger than would fit on a DC300 quarter-inch tape cartridge in the internal tape drive of all three 4050 computers, but would have fit on a 3M DC600 tape cartridge with a capacity of 600KB - it would have been very slow to load.

I designed an Arduino board to emulate the Tektronix 4924 GPIB tape drive - with the help of my software developer. My GPIB Flash Drive board contains a MicroSD card with gigabytes of storage and the Flash Drive emulates a GPIB tape changer, storing all the files of a "tape" in a single directory. I have also attached to this post a photo of my GPIB Flash Drive.

I have recovered almost 100 Tektronix 4050 Tapes and posted the ones I think are the most interesting at this time on my github repository for Tektronix 4051/4052/4054 computers: https://github.com/mmcgraw74/Tektronix-4051-4052-4054-Program-Files I included Tektronix published MATH volumes 1, 2, and 3 and Electrical Engineering, but I don't think they have a lot of use today. I have in my collection but not recovered tapes on Project Management, Statistics, and over 100 more tapes from the very active user group, which Tektronix made collections and published abstracts in their newsletter and the newletter customer got the tape for free. Commercial software like CAD programs were likely encrypted to eliminate copying - since Tektronix 4050 BASIC included a SECRET command which would then encrypt the program file as it was recorded to tape and add a SECRET flag in the tape header that would signal to BASIC ROM when that file was accessed to decrypt the program when it was loaded into memory. One big limiter to the size of the program was RAM in the 4051 was limited to 32KB and the 4052 and 4054 were limited to 64KB of RAM, although Tek BASIC did include commands to allow program "chunks" to be overlayed as necessary. Tektronix used those commands in their 4050 System Tape which was shipped with every system and included a tutorial on many of their BASIC commands. The tutorial ran on the original 4051 with 8KB of memory, and if the program detected 16KB of memory it would APPEND larger program files to speed up the tutorial.

Raspberry Pi 5 / RP1 chip support for Neopixels with Python bindings coming soon 🎉💡🖥️🌈🐍

Hot off the PIO-presses, our resident Jepler created a Python binding for the Raspberry Pi 5 that lets us use the RP1 chip

on the 5/500 series boards to drive Neopixels using PIO. This is great because we can now use Neopixels

and friends on the latest Pi boards, and we can use any pin because PIO is not limited by underlying peripherals. You do need the latest kernel and firmware, so it is not quite ready for prime-time, but once piolib

is more readily available, we'll be able to have folks test this out.

Now that I've calmed down from all the excitement of last night/this morning: it's very funny to me that a mass-produced product like the SilverLink could have a failure mode where it more-or-less just turns back into a development board. That's the sort of behavior you'd expect from a bespoke arduino-based automatic cat door you bought from a guy who builds them in his garage and sells them for cash under the table, not Texas fucking Instruments.

Who ships products with the default "waiting for firmware" fallback mode still enabled? Furthermore, who ships products with the default "waiting for firmware" fallback mode still enabled and then doesn't include the option to re-flash that firmware in any of their products?

Insane.

So I've decided to try something using my LittleBits Arduino bit and my LittleBits Adapter Eurorack module: the Dumbest Possible Quantizer.

(To overexplain, a quantizer takes a continuously varying voltage as an input and outputs a voltage that follows it, but in defined steps. The usual use case in Eurorack is mapping a control voltage onto the levels needed to produce, in the volt per octave tuning, a musical scale; you run random voltage levels through and get more musical results.)

Quantizer modules typically support different scales, modes, and keys, and sometimes even temperaments, but for the Dumbest Possible Quantizer, I'm limiting things to the bare 12-tone chromatic scale. And as suits the title, I'm doing this in the simplest possible way: I'm taking the 10-bit ADC value of the input — a number between 0 and 1023, covering from 0 to 5 volts — and mapping that onto the 60 midi notes that cover those five octaves. I'm then immediately turning around and mapping those 60 notes onto the 8-bit (0-255) value that the PWM "analog" output can take. This is nobody's idea of the proper way to do this, but since I actually had decent success using the second half as a USB MIDI to CV converter on this board already, it has a reasonable chance of approaching the desired functionality.

Long term, of course, I intend to build or otherwise acquire a quantizer module with real functionality, probably using a proper DAC; I'm following the in-development Teensy 4.1-based Ornament and Crime upgrade with great interest. But I really want to see how much I can do with very low effort!
