Hi everyone! happy to joined you in this forum :wink:
I want to have 2 single edge pwm (pwm6 and pwm1) in outputs of lpc2138. but I don't know why I have only one pwm signal!! I mean when I activate them only 1 output generate the signal. I want 2 signals that are inverted and non-inverted
whats wrong with the code ?
I use IAR as compiler.
in its library I have:
and in the main.c
