MSP-EXP432E401Y: Migrating Programs written for the MSP-EXP432P401R to MSP-EXP432E401Y

Part Number: MSP-EXP432E401Y

Tool/software:

Hello!

I recently purchased an MSP-EXP432E401Y after I completed a semester at Virginia Tech using MSP-EXP432P401R along with the BoosterXL MK II. My first point of trouble is that there does not seem to be an LCD Driver folder for the E401Y. I wanted to make my own LCD Driver, but the commands that come with the SDK are completely different from the P401R. To add to this frustration, the implementation of these commands are not 1 to 1 either. On the P401R, one command can be used to initialize a GPIO pin and set it as an input with a pull down resistor. The E401Y requires 2 to 4 additional commands to implement this function. Does anyone have any advice on this matter; otherwise, I will likely have to source a P401R for my own use.

Sincerely,

Daniel

    MSP432P is an obsolete device. It is a very different MCU from MSP432E in terms of SDK collaterals. MSP-EXP432E401Y does not come with a LCD controller. However, the SDK does come with LCD driver. You can find them in C:\ti\simplelink_msp432e4_sdk_4_20_00_12\source\ti\grlib.
