Hi,
We are currently attempting to migrate our nrf5 SDK code to NCS, on a custom board based on nrf52833.
We have an accelerometer on the device with configurable interrupt pins, and we know they are configured correctly because if we read the relevant interrupt register, we can see when a movement happens or not.
However - we have been unable as of yet to get the interrupt to trigger on the MUC level.
This is our code currently - note that I have tried several different flags of GPIO_INT_* on gio_pin_interrupt_configure_dt, as well as adding to gpio_pin_configure_dt:
const struct gpio_dt_spec int1_spec = {
.dt_flags = GPIO_ACTIVE_HIGH,
.pin = 10,
.port = DEVICE_DT_GET(DT_NODELABEL(gpio0))
};
bool init_acc_gpio_and_int(void)
{
int err = gpio_pin_configure_dt(&int1_spec, GPIO_ACTIVE_HIGH | GPIO_INPUT);
if(err){
printk("int1 input init failed (%d)\n",err);
return false;
}
printk("Pin is %u\n",int1_spec.pin);
err = gpio_pin_interrupt_configure_dt(&int1_spec, GPIO_INT_EDGE_RISING);
if(err){
printk("int1 interrupt init failed (%d)\n",err);
return false;
}
printk("Pin is %u\n",int1_spec.pin);
gpio_init_callback(&cb,int_cb,BIT(int1_spec.pin));
err = gpio_add_callback(int1_spec.port,&cb);
if(err){
printk("Failed to add int1 callback (%d)\n",err);
return false;
}
return true;
}
Is this the correct mode of operation? Do I need to add something to the devicetree (.dts) for this to work?
Thanks!
Roi
