Pinmux Configuration file - how to add ADC in-channels declaration?

Jacek Jaworski

Hello,

I have a set IDK AM437X with SYS/BIOS SDK and launched an example 'motor_control'.

In taskFxn there is a Board_pinMuxConfig function responsible for peripherals init declared in structure 'am437xIdkMux'. One of them is ADC0, however after writing a very basic configuration (I wanted to use a few channels from Industrial Connector) the ADC_AINx channels doesn't give any measure - it seems the module works anyway so I think the AIN pins weren't initialized properly (except for detailed ext_hw_trigger)...

Could you tell me where I can check the pinmux 'hardware' configuration? I've found only am43xx_idkevm_pinmux_data.c but this file doesn't seem to be included in motor_control project. Moreover, the pins ADC0_AIN0 - ADC0_AIN7 are not declared in am43xx_pinmux.h file so I don't know how to add appropriate pins in gAdc0PinCfg structure located in am43xx_idkevm_pinmux_data.c...

Thanks!

JJ
