Here's the code I am using to control 5110. It uses USCIB (2553) but USI (2231) can also be use without any problem or major updates. There is still a lot of work to be done, but basic text and some g

I wrote some code for the nokia lcd using spi a couple of months ago and after seeing Robs post I thought I'd post mine as well. sorry about the video quality I lost my good camera in a drift boat ac

Updated original post with new code. Added simple graphic stuff, 8 x 8 pixel graphics can be displayed, rotated, and flipped. Rotating is not very efficient, maybe there is another way of doing it.

Hi there,

 

can somebody give me a little jump start to this Display.

I am using a Launch Pad with an G2553, CCS 6 with Win7.

If i copy Rob G's Code to a new Project (main.c and PCD8544.h) an Build it i am getting 34 Errors.

I will try to solve this problems, but i am wondering about that much Errors.

Maybe somebody can give me a advice. I think i made a basic error and the code is fine.

thanks for your help,

 

Max

Thats really weird. Finally it runs. But i think there is another error.

void writeToLCD(unsigned char dataCommand, unsigned char data) {
LCD5110_SELECT;
if(dataCommand) {
LCD5110_SET_DATA;
} else {
LCD5110_SET_COMMAND;
}
UCB0TXBUF = data;
while(!(IFG2 & UCB0TXIFG))
;
LCD5110_DESELECT;
}

In line 10 should be a { instead a ; ?

 

The Display now works nice.

Thanks for your help

Hi @@RobG ... 

 

If you have some additional advice on how to get your code working - I too have a huge number of errors - exactly like the poster on 3 aug 2015.   My CCS6 build looks the same as his screenshot with the first error starting at line 64 (   int c = 0x20;) then onwards.   I compiled the code today.

 

I followed your advice (see the note I cut / paste immediately below) but with no positive result.   It is very strange.

 

And, in fact, when I tried your ' 4 channel - voltmeter - on  - a 5110' - elsewhere in this forum -  but I got the same huge number of errors.     I had no time to investigate then.

But thought to bring it up now - I have 5110 displays on hand and would love to use them !

 

Thank you.

Cheers.

This is weird, I got the same error when I created new project.

Comment out line right above first error, //setAddr(0, 0); 

Build, then un-comment that line and build again, error should disappear.

Super big thanks.

I downloaded your main.c (5.49KB, your post just above) and replaced the old main.c with the new one.    But not PCD8544.h (so as to try one step at a time).

 

>>>>>    It worked.      It compiled and dowloaded into the 2553LP.  No 5110 attached at the moment.    No errors in the original PCD8544.h file.

 

I'm on two machines here:  Win10 and Vista.     Vista worked, next I'll try Win10.    I'm also on CCS = 6.1.1.00022 on the Vista, 6.1.3 on Win10.   (but I'm quite sure I got the same prob on the Win10 machine with CCS 6.1.3)

 

 

I have no clue at all why this happened ---   and FWIW, the same thing happened with your 4 channel voltmeter onto Nokia 5110.

Maybe the forum download put in non-printing chars?    But I'm not going to debug that one...

 

Anyway, thanks again.

 

Next step is to wire up the Nokia 5110 and try out your excellent code.

 

Cheers.

Yes, I am actually in the process of doing it.

 

But going back to the problem, looks like compiler doesn't like when declaration is in the middle of statement block and there's no white space before the type. Moving declaration to the top of block or adding white space fixes the problem.

void clearBank(unsigned char bank) {
setAddr(0, bank);
int c = 0; //<-- causes error
while(c < PCD8544_HPIXELS) {
...
void clearBank(unsigned char bank) {
int c = 0; //<-- OK, declaration at the top
setAddr(0, bank);
while(c < PCD8544_HPIXELS) {
...
void clearBank(unsigned char bank) {
setAddr(0, bank);
 int c = 0; //<-- OK with white space (that's why formatted code works)
while(c < PCD8544_HPIXELS) {
...

You can reproduce it in new project like this:

#include <msp430.h>
/*
 * main.c
 */
int main(void) {
    WDTCTL = WDTPW | WDTHOLD;	// Stop watchdog timer
int c = 0;
	return 0;
}
