Hi! I have problems with mcb2100 !Iam trying to use SPI on this board,sck is working well but problem is, that i don't ever get anithing in S0SPDR or out of this register.Is it posibel that i physically destroyed MIOS pin on chip!i have external pullups on SSEL! This is the code!
#include "lpc21xx_keil.h" int main(void) { int i; PCONP |= 1<<8; S0SPCCR = 0X80 ; PINSEL0 |= 0x5500; S0SPCR |= 1 << 4; S0SPCR |= 1 << 5; while (1) { while (!(IOPIN0&0x20)){} //(MISO mora biti 1) must be 1 S0SPDR = 0x0; //start SPI transfer 1st byte while (!(S0SPSR & 0X80)){} // cakaj na koncan SPI transfer i=S0SPDR; } }
