Hi friends ,I encountered a problem with serial terminal and ftdi.Let me explain.Stm32f103 is sending data to Ftdi and Ftdi is sending this data to serial terminal and I can see data, but I couldn't manage to send data to Ftdi from serial terminal.If I try with ESP8266(this is module with usb) I can send AT and I receive OK also I can see my data on terminal that I want to send ,but if I try with ftdi stm32f ,when I try to enter any key on keyboard I can see led activity on FTDI but there is no any command on terminal and stm32f doesn't receive any command from terminal.
Did you check the electrical connection between FTDI and the STM32?
I handled it,it was about terminal settings.I didn't know it.But when I use ESP8266 module it worked ,it has different usb to ttl converter,but no problem.I used hyperterminal file->options-settings->asci settings and show chars
