My first try at PWM with an NXP chip but I am having trouble getting output on the pins as shown below.
Can somebody show me what I am doing wrong. The code is messy with different number formats, I have spent hours fiddling with it.
LPC1115F/303
#ifdef __USE_CMSIS
#include "LPC11xx.h"
#endif
//#include <cr_section_macros.h>
int main(void)
{
/*32B0MAT0*/
// LPC_IOCON->PIO1_6 |= 1<<1; //This works
LPC_IOCON->PIO2_5 |= 1<<0; //This doesn't work. No output on pin
/*32B0MAT1*/
// LPC_IOCON->PIO1_7 |= 1<<1; //This works
LPC_IOCON->PIO2_6 |= 1<<1; //This doesn't work
LPC_SYSCON->SYSAHBCLKCTRL |= 1<<9;
LPC_TMR32B0->PR = 0x0;
LPC_TMR32B0->MCR = 1<<10;
LPC_TMR32B0->EMR |= (1<<5 | 1<<7);
LPC_TMR32B0->CCR = 0x0;
LPC_TMR32B0->PWMC = 0x03;
LPC_TMR32B0->MR3 = 8191;
LPC_TMR32B0->MR0 = 4095;
LPC_TMR32B0->MR1 = 6000;
LPC_TMR32B0->TCR |= 0x03;
LPC_TMR32B0->TCR &= ~(0x02);
while(1)
{
}
return 0 ;
