np0_hal_read Example

Description

This example demonstrates the usage of the nPZero driver to setup the ADC and there threshould's. Booth ADC's (Internal and External) are set in the example code, the ADC_IN pin for this example is connected to VDD.

Code nPZero HAL read example

Code snippet ...

np0_status_e np0_hal_read(uint8_t slave_address, uint8_t slave_register, uint8_t *pData, uint16_t size, uint32_t timeout)
{
 uint8_t transmitData[] = { slave_register};
 
 if (HAL_I2C_Master_Transmit(&m_hi2c1, slave_address, transmitData, sizeof(transmitData), timeout) != HAL_OK)
 {
    return ERR;
 }
 
 HAL_Delay(I2C_DELAY_MS);
 
 if (HAL_I2C_Master_Receive(&m_hi2c1, slave_address, pData, size, timeout) != HAL_OK)
 {
    return ERR;
 }
 
 return OK;
}

Note

• Adapt the code to match your MCU throw np0_hal_init.
• Consult the nPZero driver function documentation for precise function usage.
