Re: How to connect USB keyboard to ESP32?

It works! This is video of wireless USB keyboard connected to native Arduino Due port, its key presses being forwarded to ESP32 MicroPython REPL with Oled display. The video shows all, but the Oled display cannot be seen detailed enough. The sketch does use Arduino USBHost library KeyboardController...

Re: How to connect USB keyboard to ESP32?

It is so simple to drive ESP32 (MicroPython) from Arduino Due. Due has 4 hardware serial interfaces, I used Serial1 and connected Pin 18 TX1 to ESP32 RX (and GND/3V). This sketch just triggers several MicroPython calculations: void setup() { int a,b,c; Serial1.begin(115200); for(a=2; a<=5; ++a) for(...

Re: How to connect USB keyboard to ESP32?

I found a way to use wireless USB keyboard with ESP32, just use Arduino Due with its USBHost library: https://www.arduino.cc/en/Reference/USBHost https://stamm-wilbrandt.de/en/forum/IMG_181218_093906.jpg I ordered two <4$ "USB host mini shield" for Arduino Pro Minis I have for much smaller (and chea...

Re: Getting the uptime

Interesting. I looked into ESP32 (and ESP8266) overflow for MicroPython utime module ticks_ms() and ticks_us() functions: https://forum.micropython.org/viewtopic.php?f=2&t=5528&p=31855#p31855 Both do return uint32_t, so overflow after 71 minutes / 49 days. Interestingly ESP8266 MicroPython implement...

Re: How to connect USB keyboard to ESP32?

> Can you confirm it is ble keyboard on that picture? > It is not, it has USB dongle, so it is a USB keyboard. I was fine with no keyboard for ESP32. Until I just now was able to use boochow's gist for 128x64 Oled console and redirecting MicroPython REPL to it. https://forum.micropython.org/viewtopi...

These are the steps to get MicroPython with OLED setup with just WebREPL and WebREPL tools: https://github.com/Hermann-SW/webrepl flash any ESP32 MicroPython to module with esptool.py https://micropython.org/download#esp32 open screen session screen /dev/ttyUSB0 115200 do "import webrepl_setup", ena...

Re: Micropython as debug shell for ESP32 (and its OLED)

A year is gone, and lately I worked a lot with ESP-01s modules (the 1MB new version of ESP-01) running MicroPython. Reason for ESP-01s instead of ESP32 is ESP-01s module 1.5g weight. It is part of remote servo bomb drop mechanism and will be attached to flying drone. The ESP-01s MicroPython will be ...

Re: How to connect USB keyboard to ESP32?

Because you can't connect USB keyboard that doesn't mean you can't use keyboard at all. True. You can use 4x4 matrix keypad I thought about that, and using its "#" key as "E" and "*" key as "F" I could enter one ASCII character for ESP32 MicroPython console with two key presses hexadecimally. But t...
