Trouble with programming Atmega328p with CP2102 usb to ttl module #41

Open BinaryBark27 opened 2 years ago

BinaryBark27 commented 2 years ago

hello, I need to program the Atmega328p with a USB to TTL module (cp 2102). my module does not have a DTR pin and I am not able to program using it. whenever I try programming the atmega chip it displays an error stating that "attempt 10 of 10, not in sync".

please can anyone help me with this?

If you have an Arduino Uno with a socketed chip you can program a new chip in the socket by using an ICSP programmer such as USBtinyISP. Alternatively you can build it up on a bread board and program it via a regular Arduino ( https://www.electronicshub.org/burn-bootloader-on-atmega328/).

If you have an EPROM Programmer such as Minipro TL866, you can add bootloader using it as well (hex file is buried somewhere in Arduino IDE installation).
