Finally after much back & forth, I am getting very used to Tasmota flashing and even compiled my own binaries for the stepper motors and MCP23017 support!
While I am getting comfortable using these boards (Sonoff, NodeMCU, D1 Mini) around my house, I am curious if there are any documented limits or expected points of hardware failure based on read, write, CPU cycles etc.
If anyone has deeper knowledge of these hardware(s), please point me to the right resource.
Thanks,
So retaining messages on MQTT could be a good way to not write state in flash, please correct me if I am wrong here as I have been using more and more of MQTT retain options for switches.
I’m smashing my head against the wall trying to use some stepper motors (L293D) thru an MCP23017 and ESP32, did you manage to make it work? If so, could you help me point out how you managed to do it?
thanks a lot
I’m creating an open source hydropnics system and its for that =) GitHub - jnrivra/QiU
You can use ESPHome instead of Tasmota and may not have to compile custom binaries for motor’s driver board
First try the motor with a ESP board without the complexity of MCP23017, as MCP23017 requires compilation of custom binary and lot can go wrong with those steps.
