I am trying to use the FT232R chip in order to allow for Serial communication between a board based on the ATMEL SAMD21 chip and a PC. I need this in order to obtain input from the user, and display some sensor output to the terminal to alert the user.
In the FT232R datasheet, it connects RTS and CTS of the FT232R to RTS and CTS of the microcontroller for it's UART example, but there are contradicting opinions about whether RTS and CTS are essential for proper communication. How do I know if RTS and CTS are used in this case, and whether my application would function properly without them?
Thanks
