CCS/MSP-EXP430F5438: MSP430 : Graphic text on LCD with Variable value instead of contrant

Intellectual 375 points

Part Number: MSP-EXP430F5438

Tool/software: Code Composer Studio

Hi ,

I am working MSP-EXP430F5438 experimenter board.

I have learned to develop LCD , Audio and Timer code with Grlib and other example codes.

I was able to disaply graphic Images and Texts on LCD. Text displax with below finction.

Graphics_drawStringCentered(&g_sContext,"Welcome ",AUTO_STRING_LENGTH,69,27,TRANSPARENT_TEXT);

However, here the text is alway a constant like "Welcome " in above function. I would like to Change the text depending on the data received over UART or ADC.

So, I will know what data has been recieved over UART or ADC. Or depending UART command/data, I would like to Display different text.

Please let me know if we can Change text as per my requriement.

just create a string buffer and make sure that the string is terminated with a '\0':

char msg[32] /* Sets aside 32 bytes for a message */

strcpy(msg, "Hello");

strcat(msg, ",World!\n"); /* these functions make sure the string ends with '\0' */

Graphics_drawStringCentered(&g_sContext,msg,AUTO_STRING_LENGTH,69,27,TRANSPARENT_TEXT);
