#135775 - keyboard clock & system clock Responding to: ???'s previous message |
I know this expression, so I just take a flag on the ISR and make my works on the main menu. I cant understand how cannt catch, because keyboard clock frequency is between 10 khz and 17 khz, but my microcontorller work with 22 mhz clock speed. Is ýt normal ? |
