How to emulate this IC TL494 on ATMEGA128L using C programming

[kunal5959]

I want to write a code in C for microcontroller ATMEGA128L so that i can replace the complete functionality of TL494 IC with the code.

. Data sheet of TL494:-

Being a beginner in embedded programming i am a bit confused how and where to start with. Can anyone please suggest me some tutorials or links where i can learn the coding of such emulations.

This will end up being slower than the internal PWM hardware.

Have you tried to see what F you need and what pre-scaler changes can be made to default counter clock?

For standard Arduinos the system clock is 16MHz so that the timers are clocking at 250kHz by default. Phase correct 8-bit PWM mode takes 510 clocks to cycle and fast 8-bit PWM mode takes 256. This means a frequency of 490Hz for pins 5 and 6.

490 Hz is also ok for the project..!!!
