Hi,
While I was testing a Grove LCD RGB display using an AXE118 (20M2 V8.A) I came across an I2C problem.
SDA (B.5) and SCL (B.7) are tied to +Vcc using 4.7K resistors.
Blockly program :
On the scope both lines remain to 1 ; there is no sign of I2C activity.
When I set both lines to 0 (low), it works. Seems there is no electrical problem.
Did I miss something?
