Hello All,
I am working on a Universal infrared receiver using QG8.
As VCC i have dropped 5V to 3.6V using 2 diodes in series. The output pin PTAD1 drives a relay through a transistor.
The transistor turns on when the code is run through USBSPYDER and subsequently turns OFF also, as intended. But when i connect my circuit to independent 3.6V(which i generate from 5V), the transistor turns ON but it never responds after that. Is this something related to RESET? i have disabled COP.
Kindly help me as always.
Thanks and Regards,
Ameya
You should try to use a voltage regulator instead of series diodes (e.g. fixed 3.6 volt output, low drop, like LP2981).
Please write again, if problem persists.
