MSP430FR6989: Serial port monitor is not working

Salibensuleiman · May 31, 2018

Dear all,

I have the following code , I want to display the value of the variable y22 but nothing shows up in the serial monitor (com16), I tried to dispaly it in LCD but nothing shows up as well, I'm using Energia 1.6, the folder under C and I reorient the jumpers TXD and RXD.

I want also to display the value of IN22 inside analogWrite(35,IN22).

Could you please verify that for me.

Thank you.

Concentrate on one problem at a time.

Create a new project.

Write a program that tests out only the serial port.

Create another project that tests out only the LCD.

Divide and conquer!!!

Once you have those working then you can get back to that crazy math you are trying to do!

Salibensuleiman · June 1, 2018

Thanks for the replies, yes it is a lot of calculations, I posted the whole code because I thought it might help but the issue is :

I want to display two voltages, one of them I read it through analogRead function "y22" and the other I calculated it inside the code "IN22" , in serial monitor but I found the serial monitor is empty.

I tried this small code from Energia examples but nothing shows up, I just changed the pin A3 to A8

void setup() {
Serial.begin(9600); // msp430g2231 must use 4800
}

void loop() {
int sensorValue = analogRead(A8);
Serial.println(sensorValue);
delay(1); // delay in between reads for stability
}

Couple quesitons:

You mentioned "I reorient the jumpers TXD and RXD.". In what way did you reorient them? If you are indeed using the MSP430FR6989 LaunchPad then you do _not_ need to change the jumpers.
Are you sure about the COM port number?
What version of the MSP430 core do you have installed. Make sure you update to the latest (1.0.3) using the Energia boards manager.

Salibensuleiman · July 13, 2018

Thanks for the reply, I'm still have the same issue, I attached the photos of the Energia version and the the port names, I tried different ports but no success. My main issue now is the serial print

energia · July 13, 2018

Tools->Board->Boards Manager...

Not that this is only available in Energia 18 and later.

Thanks for the reply, I'm still have the same issue, I attached the photos of the Energia version and the the port names, I tried different ports but no success. My main issue now is the serial print

You should be using COM16. What baudrate do you have set in the Sketch (the number in Serial.begin(....)) and does that match the baudrate in the Serial monitor (lower right corner).

Can you please try the Sketch "File->Examples->04.Communication->ASCIITable". The baudrate is set to 9600 so make sure that it matches the baudrate set in the Serial monitor.

I just verify it I'm using COM16 and the baudrate is 9600 in both Serial.begin(....) and in the monitor.

I tried the example but nothing shows up in the monitor.

Does the USB version in the laptop has any effect? please check the attached file, if so how to know my USB version? and does the existence of CCS has any effect as well.

Also does the eZ-FET REV 1.2 that is written on the board has any effect?

I think the issue is resolved now, so the first thing is to update MSP430 core as you mentioned before.

The 2nd thing is I put pack the jumpers TXD and RXD in their original orientation as when I bought the board first time.

Thank you so much for your help.
