Not able to generate 6 step pwm signal using timer1

[Ajadh.1]

Hi,

I am working with stm8s105c6 controller. I want to generate 6 PWM using timer1. For that I am using 6 step PWM sample. I am getting pwm at pc1, pc2, pc3 but complementry pwm at pb0, pb1, and pb2 is not available.

At pb0, pb1 and pb2 I am constantly getting 5V Dc. why?

will you plz help?

Thanks

If you get constant 5 V, something is wrong. Either your supply voltage if to high ( 5 V vs 3.3V) or your drive 5 V to a non-5 Volt tolerant pin.

PB2,PB1,PB0 has default function "analog input". You have to remap their function to TIM1 complementary outputs by programming option bits.

how should I program option bits?

Please guide

thank you!

I have set option bits too. Still I am not get complementary waveform at PB2 PB1 PB0. Now I am not getting 5v dc as am getting initially before option byte set.

But now only noise is present at this pins.

do i have to change anything else as hardware point of view or software

Thanks in advance

I have solved the issue, some changes I have done in hardware.
