EB-LM4F120-L35 boosterpack interface to EK-LM4F120XL Launchpad

Other Parts Discussed in Thread: MSPWARE, BOOSTXL-K350QVG-S1

I bought the Booster from Mouser Electronics with the following details: K350QVG-V2-F Lot: MAEBIT04 I am trying to interface to stellaris –launchpad EK-LM4F120XL with no success thus far. Driver that comes with the grlib demo program is Kentec320x240x16_ssd2119_8bit.c and the introduction suggests it is written for a parallel interface to SSD2119. PS3 = 0 PS2 = 0 PS1 = 1 PS2 = 1 //Kentec320x240x16_ssd2119_8bit.c - Display driver for the Kentec // K350QVG-V2-F TFT display with an SSD2119 // controller. This version assumes an // 8080-8bit interface between the micro // and display (PS3-0 = 0011b). The physical board has PS3- PS0 all connected to 3.3V (PS3-0 = 1111b) and that would suggest a 4-wire SPI interface What am I missing?

    The MSPware BOOSTXL-K350QVG-S1 example for the MSP432P401R Launchpad, which does work, uses the kitronix320x240x16_ssd2119_spi.c driver.

    The TivaWare example which uses the Kentec320x240x16_ssd2119_8bit.c driver is for a different boster pack EB-LM4F120-L35 which uses a 8 bit parallel interface.

    It looks the SPI driver required for the BOOSTXL-K350QVG-S1 hasn't been ported to TivaWare. To use the BOOSTXL-K350QVG-S1 with the EK-LM4F120XL I think you will have to port the SPI driver yourself. The kitronix320x240x16_ssd2119_spi.c driver from MSPware should provide a starting point.

    Hello Chester,

    We have an action to change the drivers for serial interface for TM4C123x devices as well. Though not in the next TivaWare release.

    Hello John,

    There is a post on the forum where another member did port over the drivers from MSP to TM4C. May be a search on forum will help

    Regards
    Amit

    Thank you both. This clears up the issue. I have downloaded the SPI driver for the MSP432P401R example and I will work at porting the driver. I will also weigh it against setting the BOOSTXL communication protocol to 8080 8 bit parallel.
