The errors reported by the board are in the form of audible beeps: The errors reported by the board are in the form of audible beeps.<br>
- **1 beep (low pitch)**: Motor error (see [possible causes](https://github.com/EFeru/bldc-motor-control-FOC#diagnostics)). Are you using a [single wheel](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Parameters#cd-single-wheel-use) ?
- **2 beeps (low pitch)**: ADC timeout triggered by the [ADC protection](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Input-Calibration#adc-protection)
- **3 beeps (low pitch)**: Serial communication timeout. Check possible reasons/troubleshooting tips in the wiki section for [USART variant](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Variant-USART#toolbox-troubleshooting)
- **4 beeps (low pitch)**: General timeout (PPM, PWM, Nunchuk). Check possible reasons/troubleshooting tips in the wiki section for [PPM variant](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Variant-PPM#toolbox-troubleshooting)/[PWM variant](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Variant-PWM#toolbox-troubleshooting)/[Nunchuk variant](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Variant-Nunchuk#toolbox-troubleshooting)
- **5 beeps (low pitch)**: Mainboard temperature warning
- **1 beep slow (medium pitch)**: Low battery voltage < 36V. More details in the [battery](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Battery) section.
- **1 beep fast (medium pitch)**: Low battery voltage < 35V. More details in the [battery](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Battery) section.
- **1 beep fast (high pitch)**: Backward spinning motors
### 1 beep (low pitch)
The motor is constantly monitored for errors. These errors are:
- **Error 001**: Hall sensor not connected. At any moment, at least one Hall should be high.
- **Error 002**: Hall sensor short circuit. At any moment, at most 2 Halls should be high.
- **Error 004**: Motor NOT able to spin (Possible causes: motor phase disconnected, MOSFET defective, operational Amplifier defective, motor blocked)
If you are using a [single wheel](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Parameters#cd-single-wheel-use), you can disable the unused wheel.<br>
Motor diagnostic is enabled by default, it can be disabled in config.h with DIAG_ENA parameter.
### 2 beeps (low pitch)
ADC timeout triggered by the [ADC protection](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Input-Calibration#adc-protection)<br>
### 3 beeps (low pitch)
Serial communication timeout. Check possible reasons/troubleshooting tips in the wiki section for [USART variant](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Variant-USART#toolbox-troubleshooting)<br>

### 5 beeps (low pitch)
Mainboard temperature warning. This warning is not enabled by default.<br>
### 1 beep slow (medium pitch)
Low battery voltage < 36V. More details in the [battery](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Battery) section.<br>
### 1 beep fast (medium pitch)
Low battery voltage < 35V. More details in the [battery](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Battery) section.<br>
### 1 beep fast (high pitch)
Backward spinning motors.<br>
Please also note that with `BEEPS_BACKWARD = 1` (default setting) the board also makes a beep when the motors go backwards. If running [hoverserial.ino](/Arduino/hoverserial) from Arduino the backward beeps are normal, unless you intentionally disable them.<br> Please also note that with `BEEPS_BACKWARD = 1` (default setting) the board also makes a beep when the motors go backwards.
