Soweit ich weiss sind die GPIO-Ports des Raspberry Pi nicht 5V-tolerant. Gibt es da keine Probleme mit dem angegeben Setup?
There are some errors in the scripts of Step 7:1. in function "sendToSlave" of the Master sketch there is an undefinied declaration used SEND_SIZE -> I guess it should be TO_SLAVE_SIZE2. In the Slave sketch there is a type in the declaration: #define TO_MASER_SIZE 3 -> must be TO_MASTER_SIZE ("T" missing)3. To begin of the loop there is a typo:(Wire.avaialable() == TO_SLAVE_SIZE) -> must be Wire.available ("a" to much)Unfortunately even after correcting these errors I got this not running. I can see the initial messages "MASTER" and "SLAVE #1" but no data transmission either way was possible. The hardware setup is correct because I could get a i2c transmission with a simpler sketch.
