Hello friends
i am new to this group and also new to Rabbit microprocessors..
i am trying to monitor TX pin using SPI interface...
I am using serial port B and SPI Dynamic C commands SPIwrite..
i have enabled my device as master clocked SPI mode..
Clock and CS line is functioning as per code..but i am not getting any output on
TX pin,,it is always high..
1 more thing ..i have not attached any SPI device to it..
i am just trying to monitor TX pins with different data..
I am very new to Dynamic C..so i may be making sily mistakes..
kindly help
SPI TX pin is always high

Have you tried the example SPI program supplied with Dynamic C?

Thanks friends
i was using Dynamic C sample program itself.By enabling PC4 pin for alternate function by writin in PCFR register program got working..
