Rx and Tx on Arduino go to Tx and Rx, respectively on FTDI board. I simply connect power, ground, Tx and Rx as shown here below. Using the Pro Mini, if you intend to connect the serial port to your computer using an FTDI board, do not connect the DTR line, as it will interfere with Atmel's Serial Wire Debug (SWD) interface. Plug the other side into the debugger's AVR port.įor the Arduino Pro Mini, use the mini squid cable as shown, again connecting the other side the debugger's AVR port.įor debugging with the Uno, you will need to cut the Reset-enable trace (you can always solder it back for using with the Arduino IDE): For the Uno, use the 6-pin ICSP cable.If you are on a budget, you can get it without the plastic case and be careful not to shock it. I recommend the Atmel ICE, as it provides debugging capabilities for AVR based arduinos (like the Uno, pro mini, etc) and the ARM based Arduinos, such as the Zero and Due. You can get by with a ISP programmer, but if you want debugging capabilities, which is one of the big advantages of using Atmel Studio, you will want a debugger. Download and install Atmel Studio 7 from here.
