Serial monitor bugging out on all examples #12

Open jonmccon opened 4 years ago

jonmccon commented 4 years ago

Well I thought I wired my array of v2.1 encoders correctly but the serial monitor is getting a constant signal:

Increment: 255
Increment: -256
Max!
Max!
Push: 
Increment: 255
Increment: -256
Max!
Max!

I tried using an i2c scanner for my teensy 3.2 and unfortunately I'm getting:

Scanning...
Unknown error at address 0x01
Unknown error at address 0x02
...
No I2C devices found

I've got 4.7k resistors on the i2c wires but do I need to solder the onboard resistor as well for the chain? Or should a single onboard pull up resistor be enough for a chain of 24?
