Hey ESP no worries.
I’m sadly still struggling getting I2C working. I’ve tried the default sketches on my Seeeduino and RainbowDuino and they dont seem to be talking. The RainbowDuino, per the example Sketch, is on addr 10. I decided to explicitly state that within the sketch and no differce.
From what I can surmise the pin out goes like this:
[b]Female connector J1[b]
From the top down (ie going towards the power connector)
[7] VCC
[6] Unknown (I2C Data?)
[5] Unknown (Ground)
[4] VCC
[3] TXD (Serial Transmit, AKA Arduino Pin 1)
[2] RXD (Serial Recieve, AKA Arduino Pin 0)
[1] GND
[0] DTR (Rainbowduino reset)
If both connectors, male and female, are mirrors of each other.
[7] I2C Data (AKA Arduino Analog 1)
[6] I2C Clock (AKA Arduino Analog 0)
[5] Ground
Can you confirm?
Is it possible you could release the Serial version of the Rainbowduino sketch?
Do you have any thoughts as to why my Seeeduino and Raindbowduino arn’t talking?
