Started using the Tiny 3250 which i received from Digikey.
One of the things I tried doing is using the QW / ST connector. I attached a Qwiic board (from Sparkfun ( STTS22H ) and tried the following MicroPython code:
if devices:
for d in devices:
print(hex(d))
else:
print(“None found”)
I kept getting the “None found” response when IO was expected the I2C address response.
I suspect that it may be the SDL aqnd SDA pin number used or (maybe) defaulting on freq (?)
It’s pretty easy to swap the physical pin number in instead of the GP number, etc. Been there done that. Plus, the pins used move around from device to device. I find the pinout diagrams a lot easier to use versus the schematic. For stuff like i2c and SPI anyway. The other gotcha is what pins are used for an onboard RGB LED or buttons, if present. Saving said info in a text file for said device can save you time latter on down the road. I’m switching devices quit often and it saves me looking it up all over again. :)
