Linux/MSP430G2553: UART communication using minicom

user5186658

Part Number: MSP430G2553

Tool/software: Linux

I am using minicom under the ubuntu to test UART of msp430_launchpad but did not get through it since I don't know how to setup the correct communication port of window 10. When I setup the tty0 the minicom works but it did not show me nothing. Do you have any suggestions?

Thanks,

Hi,

I'm assuming you are using the MSP-EXP430G2 launchpad development kit. This launchpad has an ez430 based debugger that facilitates programming the MSP430 and back-channel UART communication. Unfortunately, the ez430-tools are only compatible with Windows operating systems and they do not work on USB 3.0 ports. This is described in section 4.3 of the MSP Debuggers User's Guide.

Best regards,

Hi Caleb,
No. I am using msp430_launchpad under ubuntu and would like to use minicom by UART to send command to the msp430g2553.

Thanks,

Hi,

You're most likely using the MSP-EXP430G2 launchpad. Does it look like the image below:

Also, Ubuntu is a Linux based operating system so the ez430 tools will not work with it.

Hi Caleb,

Yes. I am working on this board msp430G2553 launchpad but not ez430 tools. I am using tools called msp430-toolchain and connected to msp430-gcc.

I hope we are on the same page.

Thanks,

Hi,

The MSP430G2553 Launchpad (MSP-EXP430G2) has an on-board debugger called the ez430. It is outlined in the image below. This debugger allows the device to interface to your comupter, be programmed, and communicate via backchannel UART.

Again, the ez430 is not compatible with Linux, so it will not work with your current setup.
