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...

Hi Roberthh, my GNUjmakefile contents is ESPIDF = $(HOME)/esp-idf BOARD = GENERIC #PORT = /dev/ttyUSB0 #FLASH_MODE = qio #FLASH_SIZE = 4MB #CROSS_COMPILE = xtensa-esp32-elf- ESPTOOL=esptool.py MPY_CROSS_FLAGS = -march=xtensa include Makefile BTW, Is below is normal ? it seems as I've got non support...

Hi Roberthh, Thank you for your good suggestion again. It works well with my esp8266 both 4M and 16M flash sizes. I'm gonna play with my other esp32 and esp32 with PSRAM boards which I guess that I can just release make command on particular sub directory. I can not see separated directories so how ...

Hi Roberthh,
Thank you again for your suggestion, it's working I built, flashed and run it smoothly. My next trial is add my own modules in further firmware build. I left Windows for awhile then my host computer is native ubuntu 18.04. How can I pre-compile my module scripts to .mpy ?
best regards,

Hi Robert, Yes,I've read thru on your provided link which it's same as instruction list that I did. Anyway once I tried your provided link it's responded that all tools/directory has been done then nothing is recreated. I could go to those instruction until I stuck at $ make -C mpy-cross which it re...

I tried to build first 8266 firmware as first time following http://www.microdev.it/wp/en/2018/06/25/micropython-micropython-compiling-for-esp8266/ web on my ubutu 18.04.2 desktop 64bit. Most instructions were fine until stuck at make final firmware_combined.bin file as below list. wr30000@E6430:~/M...

Thank, mattyt...I can move on now..
thank again,

Is there any kind ETA for using ADC function on ESP32? I'm using both with PSRAM and w/o PSRAM boards. Still can not be initialized ADC pin 35. (using pin 35 to avoid conflict of Wifi connection and hall sensor and also Lolin D32 pro V2 had wired pin 35 on battery voltage measure internally) MicroPy...
