Hello AVR Freaks,
this is my first post, so I hope, that I'm doing it right.
I had projects with FTDI (FT232RL) chips, which were buit in training boards, but now is time, to create some simple schematics by my own, so I bought this chip on ebay. It seems to be campatible with FTDI Basic Beakout 5V from Sparkfun.
Connections:This chip provides 5V power supply to my ATmega644(pins Vcc and GND). Pins RX and TX are connected to MCU in crossover mode. CTS and DTR aren't connected.
Problem: I can't send/receive data from/to MCU by means of USART via this FTDI chip. At the same time, leds TX and RX on chip are blinking, when I'm trying to send data form MCU to PuTTY terminal or send characters to MCU from terminal.
Although, USART code is working fine when I'm sending data to another MCU (traning board) from my ATmega644. Same code works well with training board and PuTTY terminal. As I understand, something is wrong with this FTDI chip...
FTDI driver 22.214.171.124 is up-to-date.
I spent time making search in google, unfortunaly no results. Any ideas, please?
Thanks in advance!
