Hi.
I have a problem with MOD-USB-RS232 and MSP430-CCRF. I don't get serial port communication on PCs virtual COM port. On MSP430-CCRF I'm running a program derived from example "Blinking Led sourced by RTC and USART Echo". If I connect pin 1.6 to a different USB2Serial converter I get the expected results.
What could be wrong with MOD-USB-RS232 or the configuration?
I am looking at the jumper descriptions of MOD-USB-RS232... By default they are configured for device mode.
Should I change this?
What is the intended use of MOD-USB-RS232? Is it meant to be used with CCRF?
Hello Zeronio,
By the initial way both boards are configured there would be a collision on the RX/TX lines. To have a proper communication on the UEXT you need the RX line of one boards to go to the TX line of the other.
You need to change the jumpers on MOD-USB-RS232 or the jumpers of MSP430-CCRF (BUT NOT ON BOTH BOARDS!).

Yes.

MOD-USB-RS232 is a simple board that has a CDC firmware and a UEXT connector. It can be used with any Olimex board with UEXT for testing or powering purposes.

I get it, I will try it. Thank you for your answer!
