Hi
I have 2 FRDM Kit ( KL25Z and K20D50M). I try to connect them by SPI ( one is Master, one is Slave, code of them i follow the help in CodeWarrior , see beelow).
When i debug the Salve kit. How can i know ( or see ) the Value which Slave receive in CodeWarrior program ?
it mean : how can i view that Value of InpData[BLOCK_SIZE] in codewarrior ?
