fanja Posted February 6, 2017 Share Posted February 6, 2017 I am starting with UART communication in PIC32MX795F512l(DATASHEET HERE: http://www.kynix.com/uploadfiles/pdf8798/PIC32MX795F512L-80I2fPF.pdf). This UART will communicate with PC. I was just wondering that it is important to connect RTS & CTS or just connecting Rx Tx GND will make the communication? Some websites say RTS & CTS are also important but some say that its not important. I am really confused. Please help.! Link to comment Share on other sites More sharing options...
helpifIcan Posted February 9, 2017 Share Posted February 9, 2017 RTS request to send CTS clear to send It depends on the software if it is looking for CTS RTS then it will not communicate. If the software id not looking for those terms then it will work fine. goretsky 1 Share Link to comment Share on other sites More sharing options...
