I have configured my board to use ADC on IDIO 8. I have commented out and removed pins 7 - 14 in the Board.h, CC2650_LaunchXL.h/c files. This works accordingly. However, when I then try to use IOID 12 as GPIO out it fails. Also while debugging I can see that adc on IDIO 8 is not working. Is there something really basic I missed with configuring the pin? Snippets below ->
1. Board.h ->
/* Discrete outputs */
/* These #defines allow us to reuse TI-RTOS across other device families */
#define Board_LED0 Board_RLED
#define Board_LED1 Board_GLED
#define Board_LED2 Board_LED0
#define ChargePin CHARGE_CONTROLLER
.....
2. CC2650_Launchxl.h
/* Discrete outputs */
#define Board_RLED IOID_11
#define Board_GLED IOID_13
#define Board_LED_ON 1
#define Board_LED_OFF 0
/* Charge outputs */
#define CHARGE_CONTROLLER IOID_12
....
3. CC2650_Launchxl.c
const PIN_Config BoardGpioInitTable[] = {
Board_RLED | PIN_GPIO_OUTPUT_EN | PIN_GPIO_HIGH | PIN_PUSHPULL | PIN_DRVSTR_MAX, /* LED initially off */
Board_GLED | PIN_GPIO_OUTPUT_EN | PIN_GPIO_HIGH| PIN_PUSHPULL | PIN_DRVSTR_MAX, /* LED initially off */
ChargePin | PIN_GPIO_OUTPUT_EN | PIN_GPIO_HIGH | PIN_PUSHPULL | PIN_DRVSTR_MAX,
PIN_TERMINATE
};
