Issues sending and receiving data

[Ioannis]

If you instist on using ISR for the USART receiver, why not use the USART Interrupt directly? It will not work otherwise as Richard noted.

Test your circuit and logic of the communication first with no interrupts and then decide what to do next.

Greetings Ioannis,

Yes, I know...

the problem is that, although the TX PIC 16F1508 is equipped with a EUSART module, the receiver PIC 16F1503 is not
The IOC was a workaround that i came up with to trigger the debugin command on the RX PIC.

Best regards

wow, no hardware usart is serious..... your 1503 has mssp interrupt..... if you can make all that work, you are very skilled indeed !

[Ioannis]

Then you have to run a fast loop and make sure you won't miss any byte.

Are you sure you cannot change that 1503?

Hi guys,

sorry for the late reply...

After some testing, I decided to change my 16F1503 receiver PIC to a 16F1508 which is equipped with an USART module. It's much easier to implement this way.

Thank you all for the support!
