I am running the oscillator of a 32Khz external oscilator, but the lp and xt setting are for a external crystal!!

I currently have the internal and external switchover enabled and low power timer1 is disabled.

Thnaks for all your help. I still have not been able to get it working. According to the data sheet for the 18f2523 timer1 can be used in sleep mode.

try using a string manipulation box and putting m_Send = "test," in it, instead of doing the c command box with FCV_M_SEND = 'T'.....

Here is the C code generated from the flowcode project. Can anyone see anything that im am doing wrong. The PIC never wakes from sleep mode, even though I am interupting the PIC using an external timer1 osc. //Internal functions #include "C:\Program Files\Matrix Multimedia\Flowcode V4\FCD\inter...

Thanks for your reply. I tried using a nop(); before and after the sleep command, but it still doesn't wake from the sleep command. It does wake from an idle sleep, but not from a true sleep instruction.

Hi, Having trouble using an external timer1 connected to the T13CKI pin to get the PIC to wake from sleep mode. I am basically trying to build a pulse generator. I have a 32Khz oscillator connected to the T13CKI pin. I then set up an interrupt in flowcode using the built in TMR1 interrupt function. ...
