FET430UIF + CC430F5137 + Serial UART Communication

Other Parts Discussed in Thread: SIMPLICITI, CC1101, CC430F5137, CC2500, CC2510, CC2520

Hello,

I am trying to open communications between a C# application on a Windows 7 PC with a EM-CC430F5137-900 attached to a MSP-FET430UIF Debugger, but the C# application throws an exception saying "Access to the COM port is denied" when trying to open the port.

I have previously utilized the .NET SerialPort class with the EZ430RF dongle with a MSP430x2xx device's UART controller with no problems, so I am inclined to think there is something different in hardware concerning the FET430UIF.

I also deployed the TI example C program cc430x513x_uscia0_uart_04.c which echoes a received character, but the same exception is thrown.

Has this been done before? Does the FET430UIF support serial communications to a PC? Is there an application note?

Thanks

Andrew,

Your observation is correct. The FET430UIF does not support a UART link at the same time, where the eZ430 does support a simple 9600 baud rate only link. You will need a separate UART to USB board to accomplish what you are looking for. A TUSB3410 or a FTDI chip can do what you need.

Look what this thread has made.

Ah I see. Thank you for the response.

In that case, is it possible for a EM-CC430F5137 End Device to link to a EZ430 Access Point using SimpliciTI radio comms? I have been trying to get them to link but with no success yet.

Thanks

Andrew,

I am not sure exactly what you mean, when you say Ez430 Access Point. The only solution I know if using a kit from one of our module partners.

This uses a CC1101 radio (same as inside the CC430) and then it connects to a simple UART to your PC.

Its a EZ430RF2500, MSP430 based device which supports the SimpliciTI API.

http://www.ti.com/tool/EZ430-RF2500

Our SimpliciTI Access Point needs to communicate with a PC, so this tool might be serve that purpose best since we have already developed code for it initially.

Our End Devices are switching from the EZ430-RF2500 to the CC430F5137 (http://www.ti.com/tool/em430f5137rf900) and will use the MSP-FET430UIF to program and debug them.

So both devices support SimpliciTI and I am wondering if SimpliciTI supports communication between different devices, these two in particular.

I think I have found a conflict though. EZ430-RF2500 uses 2.4GHz while the CC430 uses approximately 900MHz.

Andrew,

You are correct in your finding, the CC430x is based on a Sub1GHz radio where the RF2500 contains a CC2500 which is a 2.5GHz radio. They will not talk to each other, however the kit I proposed earlier is very similar to the Ez430-RF2500 it just contains a Sub1GHz radio called CC1101.

So to summaries;

The CC430, CC1101, CC1110 and CC112x work together if setup correctly
The CC2500 and CC2510 work together
The CC2520 and CC253x are Zigbee radios and all work together
