dwm_gpio_value_get

Reads pin value.

void dwm_gpio_value_get(uint8_t gpio_idx, uint8_t *value);

Parameters

• gpio_idx – ? 8-bit integer ? (see the section gpio_idx for allowed values)

• output – err_code [, gpio_val].

• gpio_val – ‘0’ | ‘1’

C code example

uint8_t value;
dwm_gpio_value_get(DWM_GPIO_IDX_13, &value);
printf(“%u\n”, value);

SPI/UART example

TLV request
type	length	value
		pin index
0x2b	0x01	0x0D

Type 0x2b means command dwm_gpio_value_get

TLV response
type	Length	value (see error codes)	type	Length	value
					pin Value (0,1)
0x40	0x01	0x00	0x55	0x01	0x00

Type 0x40 means err_code of previous command Type 0x55 means pin value
