Hello,
I would like to use PD7 as a GPO pin, more precisely as an SPI CS pin in TI RTOS environment. First I tried in:
GPIO_PinConfig gpioPinConfigs[] = {
...
// ADC1_CS
GPIOTiva_PD_7 | GPIO_CFG_OUT_STD | GPIO_CFG_OUT_STR_MED | GPIO_CFG_OUT_HIGH,
...
}
but does have any effect even if I disabled the USB module to work. ( I mean during the main function I do not call any usb module initialization methods.). On the LP user manual, the pin has NMI function:
B1 7 Analog PD7 128 AIN4 U2CTS - T4CCP1 USB0PFLT - - NMI - - - SSI2XDAT2
Do you think that I need to unlock NMI to use PD7 as a GPO? Do you have any sample code or snippet for my problem?
Thank you in advance,
