Problem with the LED

[nuwanr]

Hi,

I have made the decoder according to the schematic and instructions. The motor with the directions works fine but the light flickers ones the motor starts to work. The light stays on when the motor is at stop. My question is why does the light flicker once it starts to run the motor, is it because an issue with the voltage? or with a component? Where can I start to look for faults?

Thank you

The current firmware has a bug that prevents use of the LED for anything useful. I have spent some considerable time trying to track down the problem but have not yet found it.

The best place to look for faults is to examine the firmware in a PIC emulator. I am sure that your construction is OK.

Hi Nuwanr....I managed to get the function output working ok with a few tweaks to the code. It might be worth having a play with the modifications I outlined on the post at
