Hi Peter, I've got TSOP4838 38kHze receiver on my breadboard wit ESP32-PSRAM including copy ir_rx directory application already to test your ir_rx driver but unfortunately, upip could not find this package. see below message. >>> upip.install('pystone_lowmem') Installing to: /lib/ Installing pystone...

Normally I use screen to enter REPL. I recently use rshell as IDE rshell -p /dev/ttyUSB0 --editor nano --buffer-size=30 /home/wr300000> repl <---- get in repl and release machine.reset() to rerun my main.py Below is result from my main.py showing normal /sd directory and other configured variables. ...

Roberthh, yes you are right. I use bash's alias command as one character represents typing tails for erasing the chip. This time I can interrupt them within an assigned sec period. Thank you again...

@Roberthh
Because of my prior code is not successful and keep looping by sending esp O/S debug message every second to interfere the communication on UART port which making fail to connect to board anymore..

Hi Jimmo, My case is quite different, I built 8266 firmware and ran correctly. Everything is fine until I test some wifi connectivity but I forgot to disable esp O/S debug in boot.py. >>>import esp >>>esp.osdebug(None) This board always reply readable error response message from my incomplete previo...

I've just build and flash the latest uPython firmware on my ESP32 board but I still can not see uasyncio.py to import . Could you explain more on how can I get asyncio.py modules from ?
appreciate in advance,

@kevinkk525, I normally build/use micropython on esp8266 and esp32 only and I currently head up for learning on asyncio and mqtt modules to implement on mostly concern with home automation which prefer smallest configuration per ESP's chip. I've got 2x esp8266 8MB FLASH, esp32 WROOM-32 4MB Flash and...

I plan to make my either ESP8266 or ESP32 module to control bipolar stepper motor thru L298N driver board. I've got an idea to send out 4 binary bits thru 4 ESP GPIO pins directly to synchronize both coil sets inside stepper motor. My question is how to I bind 4 bit together within a half byte of uP...

Hi Roberthh,
Thanks, you are great....

hi Roberthh, After send make it then those error disappeared, could get 3 bin files and then make deploy to flash it. It seems to be fine as below response (uPython) wr300000@E6430:~/micropython/ports/esp32$ make deploy Use make V=1 or set BUILD_VERBOSE in your environment to increase build verbosit...
