Hi,
On my system (nRF52832, NCS 2.2.0), I have a pin that I have connected to a GPIOTE task that is usually triggered from a timer through PPI (see code below).
At one point in my code, I need to manually set the output state of this GPIO without using the timer.
Is there a way to manually trigger the GPIOTE task ? or should I disable the GPIOTE task and set the output pin state manually ?
/* Configure TX pin as gpiote output event using nrfx driver */
uint8_t gpiote_out_channel;
ret = nrfx_gpiote_channel_alloc(&gpiote_out_channel);
if (ret != NRFX_SUCCESS)
{
LOG_ERR("Failed to allocate out_channel, error: 0x%08X", ret);
return -EIO;
}
static const nrfx_gpiote_output_config_t output_config = {
.drive = NRF_GPIO_PIN_S0S1,
.input_connect = NRF_GPIO_PIN_INPUT_DISCONNECT,
.pull = NRF_GPIO_PIN_NOPULL,
};
const nrfx_gpiote_task_config_t task_config = {
.task_ch = gpiote_out_channel,
.polarity = NRF_GPIOTE_POLARITY_TOGGLE,
.init_val = 0, // TODO Define initial state of TX pin
};
ret = nrfx_gpiote_output_configure(ctx->hal->txPin.pin, &output_config, &task_config);
if (ret != NRFX_SUCCESS)
{
LOG_ERR("nrfx_gpiote_output_configure error: 0x%08X", ret);
return -1;
}
Regards
