Will changing the Switching Frequency, i.e Timer Value affect how long the counter will count for. I am having trouble where the counter will count to 255, but still be at 188 and switch duty cycles which causes a high. So it does not finish counting to 255 and resetting.

Hey, nice video and explanation!! Can you show us the hidden code from the timer module at 27:01 under the picture ?:D I see an assign and always block but the code is hidden :D
Thank you!

Should the timerbit in your code should be equal to TIMER_bit=16 ? because the resolution R is 8bit. The way you have it I am afraid might not be strict 50%duty cycle? Correct me if i am wron

Timer Final value is negative if we scale from 50mhz to 1 mhz

Hello, I think the equation in the vid, (duty - 1) / 2^R = 0.5, is not quite right. When you solve it for 'duty', you would get 129 for duty, which should be 128.

very nice informative and helpful video thanks very much. Please my question is in regard to the number of counts and bits choice. Can i just decide to count to any number let say 0 to 99 in my project or is there an idea behind the number of counts to be chosen for a specific application and how is that related to the frequency?

In trinary operator (x>5 && x<50)?1:0
I need to get the 1 value from 6 to 49 and remaining values 0.
Can you please guide me to get the code in verilog

hello!
can you create a digital pwm without coding?

Please answer me because I want help about PWM
