Hi to all engineers. I am working on project based on multiplex display, keypad, and DAC. Every thing is fine except one thing. I want to add blinking led like when you hit enter the led will blink plus it will display what you want. right now when I hit enter led will turn on in same loop when I add delay after led like bsf led call delay bcf led call delay this code will effect the display frequency because of it is in same loop. my question is . in your code if you want to add any led to blink how do you do this without effecting your code. if I use hardware timer TMR0,1,2 and instead of using software timer do you think it will solve this problem.
