Hi,
trying to interface a 3D compass (HCM6343) board (I2C interface, running 3.3V) with a PIC running at 5V, so I used the LL converter from SparkFun, connecting both SCL and SDA to the Tx pins of the converter board (SCL channel 1, SDA channel 2).
As usual, nothing works as it should… (the compass board worked before, when connected directly to a 3.3V controller)
Any tips/ideas before I get out the scope and start debugging this (woaw, I just hate that!!!) ???
Regards
Phil
