Useful Commands

• esptool.py -p /dev/ttyUSB0 erase_flash

• esptool.py --chip esp32 --port /dev/ttyUSB0 write_flash -z 0x1000 firmware/esp32-idf3-20200902-v1.13.bin

• ampy --port /dev/ttyUSB0 ls

• ampy --port /dev/ttyUSB0 get boot.py

• cu -l /dev/ttyUSB0 -s 115200 ~.

Quick Routines

• Quick board reflash:

esptool.py -p /dev/ttyUSB0 erase_flash
esptool.py --chip esp32 --port /dev/ttyUSB0 write_flash -z 0x1000 firmware/esp32-idf3-20200902-v1.13.bin
ampy --port /dev/ttyUSB0 ls

The final return of this routine should be

/boot.py

• Quick project upload to board:

ampy --port /dev/ttyUSB0 mkdir grid
ampy --port /dev/ttyUSB0 put o_src/grid/Grid.txt grid/Grid.txt
ampy --port /dev/ttyUSB0 put o_src/lib
ampy --port /dev/ttyUSB0 put o_src/boot.py
ampy --port /dev/ttyUSB0 put o_src/main.py
ampy --port /dev/ttyUSB0 ls

The final return of this routine should be

/boot.py
/grid
/lib
/main.py

Important: This routine does not overwrite files of the lib directory that have been already uploaded.

To Do

• Optimice and develop a lighter version of the code

Idealy work only with streams of states ands light transitions

Improvements:

• Addition of args handling in set_state_element_by_num and set_state_element_by_pos methods in order to decrease the data_structures.py module length.

Maybe MicroPython does not handle args and kwargs
