Nigel, do you remeber your IR coding I was modifying to suit my application? (turning on LEDs using IR controller)?
I nipped out this evening to get the chips blown, and, loaded them into seperate prototyping boards to see if they work.
No.
1.) The assmebled transmitter board, the LED's constantly flash at a fast rate., "without" any of the buttons being pressed. (I put in some normal LEDS to see what was happening. note - I forgot to order the BC733, using 2n3904 instead. bc733 arrives tomorrow.
2.) If I replace one of the normal LEDs with an IR one, the normal LED appears to double in brightness, as if, the IR LED is drawing no current i.e. not working
3.) pressing any of the switches does nothing.
4.) Can't test reciever board, as, nothing is transmitted. However, have tried this in optimism.
attached modified asm's in Zipped format. Perhaps My code modification created some errors? Too new to this to spot.
Perhaps my mounting of components on the board is incorrect, but, I'm sure its ok.
Would really appreciate some guidance.
(new programmer in the post tomorrow, so I can re-burn)
