Nigel Goodwin Tutorial 5

[Number17]

Hi

Ive been looking at Ir communication from tutorial 5. Ive used the code to make a transmitter and a receiver with 8 LED's. TX seems to work fine. I cant test it cuase I dont have a Sony Tv ( I looked at the ir Led through my phone camera, and it was on ). When I programmed the Rx pic, it doesnt seem to respond. All the leds stay on, no matter what I do.

On TX: Switches 1-4 on porta bits 4-7
IR LED porb bit 1
I also changed the volume up, down etc.. to numbers 1-4

On RX: IR module is on porta bit 1
LED's is on portb



Thanks

Have you altered the tutorial code at all?.

I only changed 1 part in TX

Switch1		movlw	But1
		call	Xmit_RS232
		retlw	0x00

Switch2		movlw	But2
		call	Xmit_RS232
		retlw	0x00

Switch3		movlw	But3
		call	Xmit_RS232
		retlw	0x00

Switch4		movlw	But4
		call	Xmit_RS232
		retlw	0x00

From what I understand, tutorial 5.3 read the numbers 1-9, and TX was originally transmitting vol up/down and prg up/down. So I changed it to transmit numbers 1-4
