CCS/MSP430FR2433: Impossible to print in the console variable value

PA Juglaret

Part Number: MSP430FR2433

Tool/software: Code Composer Studio

Good morning, everyone,

I use the MSP430FR2433, my purpose being to transmit information between two MSPs, I need to monitor the progress of the program implementation during the transmission. For this reason, in order to debug my code, I would like to display the value of some variables, to see if loops execute well for example. However, after several searches I still can't display the output of my "printf" in the console. However, I followed the steps mentioned on the page. (http://processors.wiki.ti.com/index.php/Printf_support_for_MSP430_CCSTUDIO_compiler) nothing is displayed in the console. Cannot find to modify the "Library Function Assumption " section as in the tutorial. However, I managed to find some parts of the values I'm looking for in a UART_analog.out file, but having a clean feedback would be more interesting for me.

Hi PA,

Are you using the MSP430FR2433 launch pad or is this a custom board?
What interface are you using between the MSP430FR2433 and other MSP? UART, I2C, SPI?

Hello Denis,
I'm using the MSP430FR2433 launch pad, my target is to send information between two MSP using a laser. But first, before working on the transmission circuit, I test my code by sending and receiving on the same MSP using the UART interface.

I remain at your disposal for further information.

Ok, sounds interesting.

On the MSP430FR2433 Launchpad, it is possible to use one UART that is connected to the launch pad header pins and another UART that can be selected with jumpers to connect to the "back-channel uart" feature on the programmer side of the Launchpad. Which one are you attempting to use?

Indeed, I use what you mention, I connect the UARTs by the pins with jumpers. I'm not sure to understand your question, but I use the Eusci of the MSP.

Ok,

Make sure you following the instructions from this wiki page.

Especially setting your heap size >=300.

Here is my code - it worked.

#include <msp430.h>

#include <stdio.h>

int main(void)

{

WDTCTL = WDTPW | WDTHOLD; // stop watchdog timer

printf("hello\n");

return 0;

}

Good afternoon,

Thank you for your help, I succeed to printf what I wanted, So now I can debug my code correctly.

Regards,

PA
