Hello all.
I have the lpi2c_master-s32k144 example compiled and running, i have added an infinite loop to keep sending a packet out on ID 0x01 which i can see on my picoscope fine, but i have tried to add some data to the buffer to send and regardless of how try to load the buffer up, i still get no data in the buffer.
Modified code below if someone can point me in the right direction please.
Thanks
Rich
