Hello, I meet some problem. The chip I used is nRF52810 QCAA, the softdevice I used is s112, I defined P0.09 as SCL and P0.06 as SDA, the TWI can't work and it stops in while(m_xfer_done==false){}.
However when I programed the same code into nRF52810 QFAA(only SCL changed into P0.18 and SDA changed into P0.14), the TWI work normally and can get data from mpu6050.
What's more, the button_0 event in nRF52810 QCAA doesn't work, although I have defined the touch, release and long push event. But when I changed the same I/O pin into button_1, button_2 or button_3 event, it works normally. All buttons are defined in same way. And when I programed the same code into nRF52810 QFAA, button_0 event can work normally.
All problem look like the code is suit for nRF52810 QFAA but not nRF52810 QCAA. What should I do, hoping for your help.
Some of the definition code is below
const nrf_drv_twi_config_t twi_config = {
.scl = 9,
.sda = 6,
.frequency = NRF_DRV_TWI_FREQ_100K,
.interrupt_priority = APP_IRQ_PRIORITY_HIGH,
.clear_bus_init = false
};
ret_code_t err_code;
uint8_t tx_buf[MPU6050_ADDRESS_LEN+1];
tx_buf[0]=register_address;
tx_buf[1]=value;
m_xfer_done=false;
err_code=nrf_drv_twi_tx(&m_twi,MPU6050_ADDRESS,tx_buf,MPU6050_ADDRESS_LEN+1,false);
while(m_xfer_done==false){}
if(NRF_SUCCESS!=err_code)
{
return false;
}
return true;
}
