MCU-PLUS-SDK-AM243X: How to configure sysconfig EPWM driver for trip zone?

Hi Traveler

We will try to enable this in SYSCONFIG in subsequent releases.

Action taken: MCUSDK-12663

For the meantime, you may set the pin-mux config manually:

AM243x LaunchPad Development Kit User's Guide

For example, if you need EHRPWM_TZn_IN0 for your purpose.
Set the required pin ‘GPMC0_AD2’ in SYSCONFIG.

Open ‘ti_pinmux_config.c’ from the generated files section and check the PIN_MODE set.

It’s set to 7, thus, PIN_MODE needs to be set to 3 for EHRPWM_TZn_IN0.

This can be done by adding a function with your required config and calling it in your codebase.

static void App_pinmuxConfig()

{

 

    /* Pinmux configuration to use TZ0 for ePWM trips */

    static Pinmux_PerCfg_t App_PinMuxMainDomainCfg[] = {

            /* TZ0 pin config */

 

        {

            PIN_GPMC0_AD2,

            ( PIN_MODE(3) | PIN_INPUT_ENABLE | PIN_PULL_DISABLE )

        },

 

        {PINMUX_END, PINMUX_END}

    };

 

    Pinmux_config(App_PinMuxMainDomainCfg, PINMUX_DOMAIN_ID_MAIN);

}
