Upon launching the example "Adafruit sesaw>NeoTrellis>basic" I get the following response:
"Could not start trellis, check wiring?"
I investigated further into the code and it is failing the I2C initial connection in Adafruit_I2CDevice.cpp:
Code: Select all
bool Adafruit_I2CDevice::begin(bool addr_detect) {
_wire->begin();
_begun = true;
if (addr_detect) {
return detected();
}
return true;
}
"I2C address detection test
Did not find device at 0x2E"
All the boards have working 3.3V regulators. The problem I'm having is true for all 4 boards! What else can I check/test?
