Problem runing my code

[Gusse]

Hi Mus.me,

I think you should turn on global interrupt enable (GIE) bit.

INTCON.7 = 1

Isn't that the master switch for all interrupts?

hello Gusse thank u for help , i did that not working, i think i have problem in slave senchronous or somethings goes off when sleep mode .im sending 4 numbers from the pc and it works great .but in sleep mode it doesntwake it up

Mus.me, HSERIN is an asynchronous serial function. You cannot awake from sleep the mcu with HSERIN you should search another way. If you have PortB.0 available then you could use the interrupt on portB.0, for instance you could connect RTS pin to portB.0 (via a level translator) and before TX you pull high RTS to wakeup the pic.

Actually on a 16F628, the USART can wake the PIC from sleep... I'd handle it outside of HSERIN though (you wouldn't be able to put the PIC into SLEEP initially from inside HERSIN anyway).

Hi, Mus

I played a bit with the HSERIN Command ... but Wake up only works in Synchronous mode ( roughly consider USART is disabled when sleep mode ... as the system clock is ... down !)

sooo ...

last option is to use a comparator interrupt: tie the comparator input to RX Pin ( seems Porta is unused ...) and use the comparator interrupt for wake up ...
