F4【UART2】Turn On The NFC Screen Electric Bicycle Display 24V/36V/48V/60V

P01: Backlight brightness
P02: Mileage unit, 0: KM; 1: MILE;
P03: Voltage level: 24V, 36V, 48V, 60V;
P04: Sleep time: 0, no sleep; other numbers represent sleep time, range: 1-60; unit: minutes;
P05: Assist gear: 0, 3-speed mode:
1, 5-speed mode:
P06: Wheel diameter: unit, inch;
Protocol 2: Wheel diameter value: 5.0 - 50, accuracy: 0.1 inch
This parameter is related to the speed displayed by the instrument and needs to be input correctly;
P07: Speed sensor count: range: 1 - 100;
This parameter is related to the speed displayed by the instrument and needs to be input correctly;
If it is a regular hub motor, directly input the number of sensors;
If it is a high-speed motor, the reduction ratio needs to be calculated and the input data = sensor number × reduction ratio;
For example: Motor sensor number 20, reduction ratio 4.3: Input data is: 86 = 20 × 4.3
P08: Speed limit: Protocol 2, range 0 - 100 km/h, 100 indicates no speed limit;
Here, the input data represents the maximum running speed of the vehicle: for example, input 25 indicates that the maximum running speed of the vehicle will not exceed 25 km/h; the driving speed is maintained at the set value,
Error: ±1 km/h; (Assist, handlebar are speed-limited)
Note: Here the value is based on kilometers. When the unit is changed from kilometers to miles, the speed value displayed on the interface will automatically convert to the correct mile value, but the speed limit value set in this menu under the mile interface is not converted and is inconsistent with the actual displayed mile speed limit value;
P09: Zero start, non-zero start setting, 0: zero start; 1: non-zero start;
P10: Drive mode setting 0: Assist drive (the output assist amount is determined by the assist gear, the handlebar is invalid at this time).
1: Electric drive (driven by the handlebar, the assist gear is invalid at this time).
2: Assist drive and electric drive coexist
P11: Assist sensitivity setting range: 1 - 24;
P12: Assist start intensity setting range: 1 - 5;
P13: Assist sensor disk type setting 5, 8, 12 magnet steel three types
P14: Controller current limiting value setting default 12A range: 1 - 20A
P15: Controller undervoltage value
P16: ODO reset setting long press the up key for 5 seconds to reset ODO
P17: 0: disable cruise control, 1: enable cruise control; automatic cruise control is optional
P18: Display speed ratio adjustment range: 50% - 150%
P19: 0 enable position, 0: has 0 gear, 1: no 0 gear
P20: 0: Protocol 2 (not adjustable)
