The LEA-Control-Board (LCB) is a construction kit to provide power electronic converters with a control board.
6-
7-
The basic module is the control board itself. It contains a powerful dual-core processor, error latches and various predefined low-pass filters to respond to input signals. An XDS100v2 debugger is directly integrated on the board.
8-
9-
The docking board is suitable for initial operation. This contains various input options (switches, buttons, potentiometers) as well as LEDs for output.
10-
11-
The external hardware monitor is for viewing internal counter variables on the oscilloscope and is mainly used for troubleshooting the control board in the overall system (control board + power converter).

### Symbol library and footprint libary
15-
The libraries are included by default. Open Kicad, load one of the projects and see the libraries:
16-
* `symbol editor` -> Search for `LEA_SymbolLibrary`
17-
* `footprint editor` -> Search for `LEA_FootprintLibrary`

### Set environment variable for 3D models:
20-
![](documentation/3d_model.png)
21-
In the main menu, first select "Preferences" and then "Configure Path".
22-
Replace the environment variable `MODEL_3D` with the current location of the 3D-models, e.g. `/path/LEA_control_board/hardware/KiCad_Library/Footprint_Library/3D_Model`.
23-
24-
Note: if you are using KiCAD6, and there is a variable `KICAD6_3DMODEL_DIR`, ignore this variable and add `MODEL_3D` as mentioned above.

## Flash XDS100 Firmware to FTDI Chip:
29-
* Watch this [video](https://www.youtube.com/watch?v=vZaF5ckf3OQ) first
30-
* Download FT Prog [here](https://ftdichip.com/utilities/)
31-
* Load the configuration file for XDS100v2 programmer: `File` -> `Open template` -> [Modified template](/software/01_Control_boards/XDS100v2_UART.xml)
32-
* Right click on `Device: 0` -> right click -> `Apply Template` -> `Template: XDS100v2_UART.xml`
33-
* Flash file: `Programm Devices` -> `Program`
34-
35-
Note:
36-
It is very important to click on "Apply Template" as shown in the video. Otherwise the controller will not be programmed correctly!
37-
38-
Note:
39-
The modified file has the `Virtual COM Port` enabled to provide UART communication. This is not implemented as in the video. To enable this, see the figure.

* Minimum PCB thickness is 2.3 mm due to the position-pin overlapping of J501/402 and J502/J403.
57-
* For automated placement, the position pin holes of the connectors J501/402/J502/J403 should be milled with a depth of minimum 1.3 mm.
