Error i2c with multiplexor #87

Closed 9acca9 closed 3 years ago

9acca9 commented 3 years ago

Hi. Im using the ht16k33 after a multiplexor in the multiplexor is on the channel 2

So i always do this I2C_address = 0x71 bus.write_byte(I2C_address,2)

But, how i cant pass that to the: " example:

matrix = matrix.Matrix8x8(i2c, address=0x70)

"

I try matrix = matrix.Matrix8x8(I2C_address,2) That dont work i get:

No worries. We can just close the issue. Seems like you've figure it out, but if you haven't, try posting the forums: https://forums.adafruit.com/ That's a better place for general project help.
