Part Number: EK-TM4C123GXL

Hi,

The EB-LM4F120-L35 does not appear to be reasily available. Is there a more up to date LCD Tochscreen booster pack available in the UK?

Best regards,

Nigel

    Hello Nigel,

    This is the LCD BoosterPack supported for EK-TM4C123GXL: https://www.ti.com/tool/BOOSTXL-K350QVG-S1

    This app note talks a bit more about LCD applications for TM4C MCUs and may be helpful to read: https://www.ti.com/lit/pdf/spma082

    Hi Ralph,

    It appears that the K350GVG is on a very long lead time everywhere.

    The TM4C123G launchpad workshop I am working through appears to be accessin the display using an 8 bit wide parallel mode, I could be wrong as the elecronic connections are not described. The K350GVG appears to be SPI only. So there will probably be issues I need to solve.

    I will skip this part for now and come back to it if needed.

    Do you know of any doccumentation covering the EK-TM4C123GXL with the K350GVG display?

    Best regards, Nigel

    Hello Nigel,

    I don't know about a K350GVG display, but for the K350QVG display we have the app note I linked previously and our TivaWare examples.

    Those examples should be using SPI and not the parallel mode.

    You can find them at [Install Path]\TivaWare_C_Series-2.2.0.295\examples\boards\ek-tm4c123gxl-boostxl-kentec-s1

    They come with the SPI driver, Kentec320x240x16_ssd2119_spi.c.

    Best Regards,

    Hi Ralph,

    Yes, I probably need better glasses.. :-)

    If the display is SPI driven in the example then it would make sense for me to adapt one that I already have. That will teach me a lot of things and may well be very useful.

    Thanks again for your help.

    Best regards, Nigel
