Well, this is a first for us…our initial prototype design for an ESP32-S3 "RGB TTL" display driver board didn't work perfectly the first time!!@!?? j/k that's like Tuesday for us…so back to the drawing board. We won't try driving the TFT from the octal PSRAM dedicated pins (35, 36, & 37 natch), which means our pin usage got squeezed out since we needed them for all the hardware and button interfacing. So we slapped on an xCA9554

https://www.digikey.com/short/qpmrj929

- picked because it's the same i2c expander used on the official EV kit

https://www.digikey.com/short/nbbjr3nh

and its pretty cheap. Now, the expander handles the three TFT SPI initialization pins, TFT and touch reset, a basic backlight on-off, and the two side buttons. That leaves us 6 GPIO free: a full SPI set and two analog pins. We will share the neopixel with the UF2 bootloader double-tap detect. Will it work? We'll find out!

DIY: Marauder with Screen and GPS For Flipper Zero

Many of you would have seen the humongous ESP32 add-on module with touch screen and GPS for Flipper Zero shared in discussion groups, forums, etc. Well, this tutorial will provide you with all the information you need to build one yourself.

This build consists of mainly 4 parts. The TFT LCD 2.8" 240x320 SPI ILI9341 Touch Display cost me around US$5.50, the ESP32-WROOM-32U module cost around US$3, the NEO-6M GPS module cost around US$2.20 and an 8dbi 2.4GHz Wifi Antenna which cost around US$2. All of these parts can be easily found in online marketplaces like Aliexpress, Amazon, etc. Here is how you need to wire them up together. How you wish to lay this out or mount on a prototyping board is entirely up to you. As long as the connections are correct, you are good to go. The GPS module is optional, and mainly, it's used for the war driving functionality.

Next, you need to download all the firmware needed from here. Please download the Bootloader, Partitions, Boot App and Firmware files for v4 (Yes, v4 files, not any others) and save it on your computer.

Now, press and hold the BOOT button on your ESP32-WROOM-32U module and connect it to your computer using a data-capable USB cable (some USB cables can only charge), then let go the BOOT button. Open Google Chrome or Microsoft Edge browser and go to ESPWebTool. Click the CONNECT button, then select the ESP32 usb serial connection. It should look something like below but can vary a little between different computers and operating systems.

Select the firmware files for each slot exactly like below (take note of the 0x1000, 0x8000, etc. and their corresponding .bin files), then hit the PROGRAM button.

When completed successfully, you can unplug the USB cable from the ESP32 module and now you can connect your Marauder module to your Flipper Zero. Please ensure that your Flipper Zero is turned off before you connect it, and also turn off your Flipper Zero before disconnecting it. The 3.3V pin is also used by your Flipper Zero's SD card reader and connecting/disconnecting external modules that use this pin while the Flipper Zero is on can potentially corrupt the SD card. So, if everything went according to plan, your Marauder module should boot up and everything should look like below.

NOTE: If your Marauder boots up, but when you try to touch the screen and get no response, try tapping around the bottom part of your screen and see if the touch panel seems to be in inverted position from the actual display. Should this happen to you, just flash your ESP32 module again following the steps above, but use the v6 firmware. This should resolve the issue.

In this build, I just prototyped this on breadboard, but you can of course make it permanent by soldering it on to a prototype board and 3D print a case for it. This setup is essentially just using the Flipper Zero as a battery pack, instead of using the Flipper Zero to control Marauder. The large screen does make some things easier to do, compared to the small screen of the Flipper Zero, and there may be some functionality (not much) that is not currently in the Flipper Zero Marauder companion app. Here is a video showing the different menus in Marauder.

Personally, I don't think I will actually want to bring something so big around with me, along with my Flipper Zero. I think what makes Flipper Zero special is just how compact it is and all the different functionality cramped into it. This would probably be better off as a standalone unit by just hooking up a battery, but that's just me. Well, that's it for this tutorial. I hope you found this helpful. If you haven’t already done so, check out my Makers & Hackers Exchange Facebook group to learn more from other Flipper Zero users.

Here's a good intro to Marauder if you are unfamiliar.

Arduino IDE wieder nutzen: Deinen Mikrocontroller von MicroPython befreien

Im Beitrag Programmieren des Arduino Nano ESP32 im Arduino Lab habe ich dir gezeigt, wie du den Arduino Nano ESP32 für MicroPython mithilfe des MicroPython Installers flashen kannst. Hier soll es nun darum gehen, wie du dieses wieder rückgängig machst und so deinen Mikrocontroller in der Arduino IDE wieder programmieren kannst.

Es gibt hierzu eine offizielle englische Dokumentation unter Reset the Arduino bootloader on the Nano ESP32, auf welche ich mich hier beziehe. Du findest somit hier die deutsche Anleitung dazu.

Was wird benötigt, um den Mikrocontroller zurückzusetzen?

Du benötigst lediglich zusätzlich: - ein 400 Pin Breadboard, - ein Breadboardkabel, 10 cm, männlich-männlich Und natürlich die Arduino IDE. In meinem Fall nutze ich die Version 2.1.1 welche du unter https://www.arduino.cc/en/software kostenfrei für Microsoft Windows, Linux und macOS herunterladen kannst.

Aufbau der kleinen Schaltung

Bauen wir zunächst die Schaltung auf und klemmen das Breadboardkabel zwischen den Pin GND & B1 vom Board.

Arduino Nano ESP32 mit Brücke zwischen GND & B1 Im nächsten Schritt wird jetzt der Mikrocontroller mit dem PC verbunden und die RESET Taste betätigt. Wenn dieses gemacht wurde, dann kann die Brücke mit dem Breadboardkabel wieder getrennt werden und die RGB LED sollte jetzt von Grün auf Lila wechseln. Jetzt können wir zur Arduino IDE wechseln.

Zurücksetzen über die Arduino IDE

Zunächst stellen wir sicher, dass der korrekte Mikrocontroller "Arduino Nano ESP32" sowie der COM-Port ausgewählt wurde. Zusätzlich muss noch unter Werkzeuge > Programmer der Eintrag "EspTools" angehakt sein.

Einstellungen für das Zurücksetzen des Mikrocontrollers Wenn diese Einstellungen getroffen sind, können wir ein leeren Sketch über Sketch > "Upload using Programmer" starten.

Arduino IDE - Upload eines Sketches mit einem gewählten Programmer Sobald der nachfolgende Text angezeigt wird, können wir den Mikrocontroller über die RESET Taste neu starten und damit ist der Vorgang abgeschlossen. Leaving... Hard resetting via RTS pin... Nun kannst du deinen Arduino Nano ESP32 wieder wie gewohnt über die Arduino IDE programmieren. Read the full article

SWORDSOFT LAYOUT SERIAL NUMBER HOW TO

SWORDSOFT LAYOUT SERIAL NUMBER CODE

However, if you have peripherals connected to those pins, you may have trouble trying to upload new code, flashing the ESP32 with new firmware, or resetting the board. More information on the ESP32 Boot Mode Selection can be found here. The board puts the pins in the right state for flashing or boot mode. On most development boards with built-in USB/Serial, you don’t need to worry about the state of these pins. These are used to put the ESP32 into bootloader or flashing mode. The ESP32 chip has the following strapping pins:

SWORDSOFT LAYOUT SERIAL NUMBER HOW TO

Learn how to use interrupts with the ESP32: Learn more about SPI communication protocol with the ESP32 using Arduino IDE: ESP32 SPI Communication: Set Pins, Multiple SPI Bus Interfaces, and Peripherals (Arduino IDE) InterruptsĪll GPIOs can be configured as interrupts. Learn more about I2C communication protocol with the ESP32 using Arduino IDE: ESP32 I2C Communication (Set Pins, Multiple Bus Interfaces and Peripherals) SPIīy default, the pin mapping for SPI is: SPI If you want to use other pins when using the wire library, you just need to call: Wire.begin(SDA, SCL) When using the ESP32 with the Arduino IDE, the default I2C pins are: The ESP32 has two I2C channels and any pin can be set as SDA or SCL. Learn how to use ESP32 PWM with Arduino IDE: ESP32 PWM with Arduino IDE I2C GPIO where you want to output the signal.To set a PWM signal, you need to define these parameters in the code: All pins that can act as outputs can be used as PWM pins (GPIOs 34 to 39 can’t generate PWM). The ESP32 LED PWM controller has 16 independent channels that can be configured to generate PWM signals with different properties. Learn how to use the RTC GPIOs to wake up the ESP32 from deep sleep: ESP32 Deep Sleep with Arduino IDE and Wake Up Sources PWM The following GPIOs can be used as an external wake up source. These RTC GPIOs can be used to wake up the ESP32 from deep sleep when the Ultra Low Power (ULP) co-processor is running. The GPIOs routed to the RTC low-power subsystem can be used when the ESP32 is in deep sleep. There are 2 x 8 bits DAC channels on the ESP32 to convert digital signals into analog voltage signal outputs. View source Digital to Analog Converter (DAC) You’ll get a behavior similar to the one shown in the following figure. You need to keep that in mind when using the ADC pins. You’ll probably won’t be able to distinguish between 0 and 0.1V, or between 3.2 and 3.3V. The ESP32 ADC pins don’t have a linear behavior.

SWORDSOFT LAYOUT SERIAL NUMBER CODE

You can also set the resolution of your channels on the code and the ADC range. This means that you can get analog readings ranging from 0 to 4095, in which 0 corresponds to 0V and 4095 to 3.3V. The ADC input channels have a 12-bit resolution. So, if you’re using Wi-Fi and you’re having trouble getting the value from an ADC2 GPIO, you may consider using an ADC1 GPIO instead. Note: ADC2 pins cannot be used when Wi-Fi is used. The ESP32 has 18 x 12 bits ADC input channels (while the ESP8266 only has 1x 10 bits ADC). These are the GPIOs that can be used as ADC and respective channels: Learn how to use the touch pins with Arduino IDE: ESP32 Touch Pins with Arduino IDE Analog to Digital Converter (ADC) Those internal touch sensors are connected to these GPIOs: The capacitive touch pins can also be used to wake up the ESP32 from deep sleep. These pins can be easily integrated into capacitive pads and replace mechanical buttons. So they can detect variations induced when touching the GPIOs with a finger. These can sense variations in anything that holds an electrical charge, like the human skin. The ESP32 has 10 internal capacitive touch sensors. So, don’t use these pins in your projects: However, these pins are connected to the integrated SPI flash on the ESP-WROOM-32 chip and are not recommended for other uses. GPIO 6 to GPIO 11 are exposed in some ESP32 development boards. They can’t be used as outputs, so use these pins only as inputs: These pins don’t have internal pull-up or pull-down resistors. GPIOs 34 to 39 are GPIs – input only pins. GPIOĬontinue reading for a more detail and in-depth analysis of the ESP32 GPIOs and its functions. The pins highlighted in red are not recommended to use as inputs or outputs. The ones highlighted in yellow are OK to use, but you need to pay attention because they may have an unexpected behavior mainly at boot. The pins highlighted in green are OK to use. The following table shows what pins are best to use as inputs, outputs and which ones you need to be cautious. Additionally, there are pins with specific features that make them suitable or not for a particular project.

ESP32-C6 Trinkey is a USB Key with Wi-Fi/BLE/ZigBee 🔑🌐🔧

Having wrapped the feather ESP32-C6 (https://github.com/espressif/arduino-esp32/pull/9961) we think it would be neat to have a USB key 'Trinkey' board for the 'C6 because with WiFi+BLE+ZigBee and USB support, this could act as a low-cost gateway or relay board. We kept it simple here: USB type A in, two buttons for resetting and bootloader-select or user input, one red LED, one NeoPixel, Qwiic/Stemma QT I2C port, and a 3-pin JST SH with gpio #0, which can do PWM/ADC/digital in case you want to add another potentiometer, relay, servo or NeoPixels (on the back you can select if you wish to 3V or 5V power). The goal here is to keep it small, cheap, and extensible. We think we did a good job; what do you think?
