I have to integrate a LCD touch display with the TI Hercules development board having tms570ls3137 microcontroller.

Could you please suggest a compatible displays. It is used for automotive application like multimedia.

Thanks in advance

Thanks Martin for the reply.

I have to procure a display. Could you please a suggest a compatible one specifically for TI-Hercules TMS570LS3137 development board.

The link that you specified is corrupted hence I couldn't get much details from it. Also as mentioned it is for RM457. Is it the same as TMS570LS3137

yep,the libraries are compatible with all versions of Hercules RMx, but first you must take into account the number of pins that the LCD TFT requires.

attached here, some images and the program code.

for use on your own you should rename the pins.

Thanks Martin. I was able to download the library file.
Which brand did you choose for a 3.2" display? Even I am in need of similar display for my experimental setup

Martin,

Do the drivers account for the endianness swap? RM devices are little endian and TMS570 devices are big endian so there may need to be some data swizzling to make the drivers work on the TMS570 devices.

Hello again, you can acquire the display of the next page.

3.2 inch 3.2 "TFT LCD module Display + Touch Screen Panel + PCB SSD1289 blue adapter with SD card slot 65 K colors

I don't have Hercules TMS as for testing and that allow me to give a conclusion on endian format.

but if you need help once implemented, we can make the necessary changes to the libraries.

Hello David,

I used the LCD display from an older TMS570 kit (http://www.ti.com/tool/tmdx570ls20smdk) and connected it to RM42, RM46 and TMS570LS1227 LaunchPad's.
The LCD is from the company AMPIRE the part number is AM-240320LDTNQW-00H. The beauty of the LCD is, that you can connected it via a parallel bus or SPI. As parallel bus you can use the EMIF on Hercules devices as it is done on the MDK kit I mentioned above. The AM240320LD seems to be EOL and be replaced by the AM240320LG which they say has the same interface.
I ported the TIVAWARE graphics library to Hercules (endianness swizzling) and modified the driver from the MDK for this purpose (SPI interface + graphics lib calls) to be able to use the LCD with the LaunchPad's

Best Regards,
Christian
