Hi there,
I am trying to achieve communication between my pc and AVR (atmega 8) using UART. For testing a LED must glow for some byte sent
The communication takes place through a usb-vritual com port-uart device (usb to mcu serial link) (basically using the chip pl2303Hx).
But the receiving MCU does not respond to the data being sent as if nothing is being transmitted.
I have all the proper drivers and cables. I tried using hyper-terminal and even my own custom made app in vb.net
However the MCU can talk with other MCU flawlessly over UART but not with the usb serial link.
here are the settings
data size 8bits
stop bits 1
parity none
baud rate 4800 (gives UBBR value 12 for atmega 8)
I've connected the Txd pin from the usb to serial adapter to Rx of the MCU uart with a common ground. Also the adapter takes care of level conversions (if any)
