Interupts going mad with 18F46K22
Posted: Thu Apr 15, 2021 6:17 pm
Hi team
Further to my ongoing investigations with the timer
viewtopic.php?f=76&t=22661[url]
I've hit another funny.
Same program, but now I've hooked up 4D Systems displays using UART channel 1 and UART channel2 instead of the 4x20 LCD.
When running the program without using Channel 1 alls well but if I enable channel 1 the interrupts cease to work. Changing channel 2 has no effect so either I'm going mad or UART Channel 1 (Port C6 and C7) is upsetting the interrupts somehow.
I've swapped the displays around but the issue follows the port, not the display.
Any ideas would be greatly appreciated
Thanks
Chris
