Hello All,
I want to generate VGA signal with microcontroller. But I have hard time finding solution online how to generate them in software. For e.g. Usually all online VGA signal generation just explains timing requirement for HSYNC and VSYNC along with back and front porch timing with for some fixed values like 640x480@60Hz or 1024x786@70Hz etc. But what is not given is how to calculate them and pixel clock and other things. So, how to calculate timing for VSYNC and HSYNC along with front and back porch for any random resolution at some random refresh rate for e.g. 480x240@60Hz?
Thanks for answers.
