Hello All,

I trying to get a square wave out of PWM5 (pin 21). Is there any trick?

Currently I have a driver that support PWM 2 (p.7), 4(p.8), and 6(p.9) but when I try to use PWM5 there is no signal output.

Only major difference in the code, is that PWM5 PINSEL1 is used,

  if (channel==5)
  {
  VOLATILE(PINSEL1) |= 0x400;
  }

I'm using an Ashling EVBA7 board,

Any ideas?
 
Kind regards,

Solved!!!

  "Port line p0.17 to 0.21 are multiplexed with the primary JTAG debug"

Kind regards,
