Determine the cause of Wemos external LED malfunction #41

Open platisd opened 6 years ago

platisd commented 6 years ago

The LED connected to the WiFi module is misbehaving (i.e is constantly turned on) regardless of the WiFi Module's pin output.

DoD:

Determine the cause of this defect (it is hardware/electrical related)
Apply corrective action (removing the LED completely is not a bad option)

This is probably related to #65

I am almost sure the problem stems from the fact that we are using software for a newer hardware version (i.e. R2 and R3) than we actually have (R1). It looks like the mapping of Arduino pin numbers to ESP8266 pins has changed between the versions! For example, for R1 hardware, pin D4 in code is actually D2 on the board!

I shall investigate this further soon to determine the cause of this defect with greater certainty, regardless of whether we maintain the specific LED on the board or not.
