Common block
Parameters
shutdown_longpress
A long press on BTN1 will shut down the display and controller. This is a delay for the long press in [ms].
If set to 0, the shutdown functionality on BTN1 is disabled.
This feature requires HW functionality called "flip-flop" to be enabled in the display and controller. (default in standard configuration)
main_scr_opts
Using this parameter, you can choose which main screens are available to the user.
| Bit | Name |
|---|---|
| 0 | Main screen 1 |
| 1 | Horseshoe speed |
| 2 | Horseshoe current |
| 3 | Speed with horizontal current bar |
| 4 | Stopwatch |
| 5 | Consumption |
| Bit position | Dec value | Description |
|---|---|---|
| 0 | 1 | Main screen |
| 1 | 2 | Horseshoe speed |
| 2 | 4 | Horseshoe current |
| 3 | 8 | Speed and horizontall current bar |
| 4 | 16 | Stopwatch |
| 5 | 32 | Consumption graph |
sub_scr_opts
Using this parameter, you can choose which sub-screens are available. Sub screen is the one-line text at the bottom of the screen.
| Bit | Name | Description |
|---|---|---|
| 0 | TRIP | Long press of BTN3 will reset the TRIP |
| 1 | ODO |
scr_elements_opts
Bitwise parameter
You can enable or disable some elements on main screens
| Bit | Name | Description |
|---|---|---|
| 0 | Time | Show time on some screens. Use this option if the display is with RTC battery. |
| 1 | Map | Show map number on screen |
| 2 | Motor temp | Show motor temp on some screens. |
| 3 | Controller temp | Show controller temperature on some screens |
- RTC battery is not present in standard display version
- Showing temperatures require LYNX v5.1.x and newer
- To properly convert motor temperature from resistance to degree, check parameters in
/mtempfolder.
options
| Bit | Name | Description |
|---|---|---|
| 0 | GPIO1 & 2 Turn signals | If voltage on GPIO1 it GPIO2 is higher thna 10V, turn signal LED is on |
| 1 | BTN 2 Map switch | This will enable switching maps by BTN 2 |
| 2 | GPIO1 and GPIO2 map switch | Using GPIO1 and GPIO you can change maps up and down. This disable map switch from BTN4(GPIO0) |
GPIO1 & 2 Turn signals
There are 2 posibilities how to controll turn signal LED. First is one hardware input dedigated for the LED. Second is let the MCU to controll the LED and use GPIO as input. The second option allows you to use 2 separate signals (left and right).
Please take attention to the display hardware configuration. If the turn signal LED is controlled by MCU or by 12V signal, is done by hardware configuration.
in_btn4
The display expects 4 buttons for control. One of them is external. The value of this parameter is the ID of the input for the external button.
The value must be the ID of the GDIN input on the display.
| ID | Name |
|---|---|
| 16 | GPIO0 - default value |
| 17 | GPIO1 |
| 18 | GPIO2 |
BTN4 is used as a map change button, or stopwatch start/stop button.
simulate
If you set this value to something other than 0, the display will simulate the controller connection. This is useful for testing the display without the controller.
| Value | Description |
|---|---|
| 0 | No simulation |
| -1 | Simulate connection |
| -10 | Freeze the simulation |
| Positive value | Simulate LYNX controller with given mode |
Motor temperature conversion
On some screen is option to show motor temperature. The controller is sending motor temperature in resistance and the display will convert it to the temperature in degrees.
/mtemp/R_25
Sensor resistance at 25°C in [ohm]
/mtemp/Bconst
Sensor constant.
- Use positive value if your sensor is PTC
- Use negative value if your sensor is NTC
Permanents
These permanents are for storage user settings.
If you want to change these values, use the display menu.
mph
mph/kph slelection
1 = mph 0 = kph
main_scr_id
The ID of the current main-screen. After the display reboot, it is restored
sub_scr_id
The ID of the current sub-screen. After the display reboot, it is restored
pin
User pin.
user_color
A user selected color.
no_regen_treshold
| Value | Description |
|---|---|
| > 0 | Show warning icon at full battery |
| -1 | The icon lits green in braking mode |
| -2 | The icon is disabled, SOC text is always large |
The icon will make SOC text smaller
