LAUNCHXL-CC1312R1: LCD display

Part Number: LAUNCHXL-CC1312R1
Other Parts Discussed in Thread: CC1312R, SYSCONFIG

Hello,

I got the BOOSTXL- SHARP128 and connected to the Launchpad. The LCD display worked successfully when I used the example of "display" from online resource.

But when I was tried to change the UART display to LCD display in the example of "i2ctmp":

https://dev.ti.com/tirex/explore/node?devtools=LAUNCHXL-CC1312R1&node=AOLnDlPfr.g9W8QwojjsWA__pTTHBmu__LATEST

the origin code in line 111 is:

Display_Params params;
Display_Params_init(&params);
/* Open the UART display for output */
display = Display_open(Display_Type_UART, &params);

And the result in the terminal is OK:

Now I just simply change the last line to:

display = Display_open(Display_Type_LCD, &params);

which should show the content on the LCD screen.

But no result. Is that something about the configuration?

Since I work on the CC1312R, I always have question that even you copy the same code from the example to another example code, it successfully run but outcome results are not the same.

I check every code file in both projects that are totally same, but results are not. I think it is possibly relevant to the project configuration. But I don't know where I should set up.

Did you configure the SPI bus correctly?

Could you post the ti_drivers_config.c/.h (generated files in the SysConfig folder)?

Hello,

Thanks for your reply.

I already check the ti drivers configuration as you suggested.

But I don't have the ideal to configure the setting.

So can you please tell me which files I should edited?

The files under the Generated Source or Debug ?

I tried to set up the .syscfg but one question I can't detect and select the Sharp LCD Display that connected the launchpad (already connected)?

While I checked the .syscfg in the example of Display which indeed can select the option of Sharp LCD Display.

Can you please tell how to configure it?

Hello,

As I found, the configuration of hardware is actually different. The example of Display has the options of BOOSTXL SHARP128 while another project just has the temp sensor.

How can I add or configure the BOOSTXL display hardware into the temp project for LCD output?

Is there any method to add the hardware in the project configure if required?

Best Regard

I have sent off a mail to the syscfg team to see if they can give me a guide on how this could be done.

One potential workaround is to disable syscfg and add the required code (copy/ paste from the display project)

TI__Guru**** 317180 points

I forgot a detail here. The "Use Hardware" is just to simplify setting up the required pins. If you set the "Display Type" to LCD you can set the required SPI pins manually (use the Display example as a guide)

Thanks for your help.

I think syscfg is actually the visual interface to configure the ti_drivers_config.c/.h. Because the code was changed in .c/.h once I configured in the .syscfg interface.

You can see the code in the ti_drivers_config.c for display is actually the same both example of Display and i2ctemp (I can't totally copy/paste the code becuase the i2ctemp requires the i2c configuration to detect the connected sensor, otherwise the sensor communication will not work).

The code is completely same except the comments (comments not affect the program).

I think the current issue is the configuration of .syscfg that is allowed to add the new peripheral like LCD display or i2c sensor for the project.

Can you please inform the syscfg team about this issue and tell me the solution?

See my last post, you should be able to add the required pins in syscfg.

Hello,

Which options you mean to set the pins?

The display sections?

or SPI section? (All the options here I checked are same as the example of Display)

The SPI sections configuration like below:

TI__Guru**** 317180 points

Have you set the pin mux part of these to be the same as in the display example?

I don't have the required hardware to test this with me at the moment.

0 Yuxiang Huang over 4 years ago in reply to TER

Prodigy 230 points

Yes. Everything is same as I checked.

I think the basic issue is still that the hardware of BOOSTXL LCD display is not detected in the i2c project.

According to the Introduction below, SysConfig can custom the TI launchpad and Booster Packs like my BOOSTXL LCD display.

http://dev.ti.com/tirex/explore/node?a=Zj4YMtc__5.6.1&node=AIouI6g4ejAMCyOe10iMKQ__pTTHBmu__LATEST&r=Zj4YMtc__LATEST&r=fc2e6sr__3.30.00.04&r=pTTHBmu__3.20.00.68

So is that SysConfig detect the hardware automatically (I always connected with launchpad and LCD), or set up manually?

How to add a hardware component?

TI__Guru**** 317180 points

You have to set the hardware manually. But the important thing is the pin mapping which looks correct.

Could you post the files that get generated under Debug/syscfg? (ti_drivers*)

Have you tried to monitor the SPI interface to see if you have any traffic here? Have you tried to step into the function to see what is happening?

0 Yuxiang Huang over 4 years ago in reply to TER

Hello,

As you can see, ti_drivers_config is actually the same as the example of Display, and I checked all the files.

You are right that the pin mapping is correct because all the setting in SysConfig are configured correctly.

But the SPI to the peripheral of LCD is not work, I think mainly because the SysConfig did't recognize the hardware component of LCD.

So I think maybe you can post this question to SysConfig team and ask team member that how to add the hardware component in SysConfig?

That will make the LCD peripheral recognized and configured.

Thanks for your help.

I plan to look further into this but haven't had the time yet due to other cases.

Hello,

Thanks for your help. Please update the solution when you will be available to figure it out.

Looking forward to your reply.

Thanks again!

Did you set up your defines correctly?

Hello,

I checked it and made it same for two projects of Display and i2ctmp.

But the result is same that Display can show data in the LCD while i2ctmp can't.

I think that is not point, cause SysConfig didn't show the BOOSTXL-SHARP in the hardware.

I managed to get it to work without issues. I took the empty example and added the following code in the main:

    Display_init();
    /* Initialize display and try to open both UART and LCD types of display. */
    Display_Params params;
    Display_Params_init(&params);
    params.lineClearMode = DISPLAY_CLEAR_BOTH;

    /*
     * Open both an available LCD display and an UART display.
     * Whether the open call is successful depends on what is present in the
     * Display_config[] array of the driver configuration file.
     */
    Display_Handle hLcd = Display_open(Display_Type_LCD, &params);
    /* Check if the selected Display type was found and successfully opened */
    if (hLcd) {
        Display_printf(hLcd, 5, 3, "Test my Display");
    }

In the syscfg file I did the following: (I have an old 96 display, hence the 96):

Did you set up the SPI interface?

Hello,

Thanks for your solution.

That's so weird that no results was shown in the LCD, even the same setting and code with you.

Strange. Could you try to start from the empty example like I did? Not sure why that should make a difference but I got it up and running from the empty example fast without any issues.
