    help with UART ISR

    cathal.ferrydl_1479341

      Hi,

         

      Ive been messing around with the UART function..... again. Ive implemented a simple ISR so on RX byte received which when triggered shows pn the LCD a message ISR, just to show it works.

         

      I wanted to use the ISR to fill a buffer because i dont want other code to stop running while the PSoC is polling the uart rx.

         

      I have a simple isr function and was wondering what would be the best way of filling a char array of size maybe 20 with some data in the correct order, then have the ISR exit and return back to code after that.

         

      I can send a string to the PSOC with a  specific start command i.e an 'S' followed by a number but Id need to get that data into an array first before acting on it.

         

      thanks guys
