## Application Development

This section mainly describes how to set up the hardware and software, flash firmware to the development board, and develop applications.

### Required Hardware

- 1 x SF32LB58-DevKit-LCD (including the SF32LB58-MOD-N16R32N1 module)
- 1 x display module (MIPI-DSI or DPI/RGB888)
- 1 x USB 2.0 data cable (standard Type-A to Type-C)
- 1 x computer (Windows, Linux, or macOS)

```{note}

1. If you need both UART debugging and the USB interface, two USB 2.0 data cables are required;
2. Make sure to use an appropriate USB data cable. Some cables are for charging only and cannot be used for data transfer or firmware flashing.

```
### Optional Hardware

- 2 x speakers
- 1 x TF Card

### Hardware Setup

Prepare the development board and load the first sample application:

1.	Connect the display module to the corresponding LCD connector interface;
2.	Open SiFli's SifliTrace tool software and select the correct COM port;
3.	Plug in the USB data cable to connect the PC to the USB-to-UART port on the development board;
4.	The display lights up, and you can interact with the touchscreen using your finger.

Hardware setup is complete. You can now proceed with software setup.


### Software Setup

### Power Supply Description

The SF32LB58-DevKit-LCD development board supports USB Type-C power input.

Both onboard USB Type-C ports can power the board. For flashing and debugging, use the USB-to-UART port.


### Flash the test firmware

#### Download the Impeller firmware flashing tool
Connect a USB cable to the USB-to-UART port, open SiFli Technology's firmware flashing tool, and select the corresponding COM port and firmware.
1.  Download Mode
- Install the Mode jumper cap, power on, and after startup the board enters download mode, allowing the program to be downloaded.
2.  Software Development Mode
- Remove the Mode jumper cap, power on, and after startup the board enters serial log printing mode, which is software debugging mode.

**For details, refer to&emsp;[Firmware Flashing Tool Impeller](../tools/烧录工具.md)**

#### J-Link SWD tool download and debugging

As shown in the two figures below, use DuPont wires to connect the corresponding IOs.

<div align="center"> SF32LB58-DevKit-LCD Jlink Debug Wiring Diagram </div>   <br> <br> <br> 

 
<img src="assets/58KIT-JLINK-Adapter.png" width="80%" align="center" /> 

<div align="center"> Jlink Debugger Wiring Diagram </div>   <br> <br> <br> 

 
For convenient connection, the development board comes with the adapter board shown below. The adapter board can be connected to the JLink debugger in the direction of the notch. Then plug in the included DuPont wires, and connect the other ends of the DuPont wires to the corresponding pins in {numref}`SF32LB58-DevKit-LCD-Jlink-PIN`, where VCC is the 3.3 V pin.

### LCD Display Interface

The SF32LB58-DevKit-LCD development board supports:
- MIPI-DSI interface (30p, 0.5 mm-pitch FPC connector), supporting up to 2-lane data transmission and up to 1280*800 resolution
    * Supported display model: [TFT-H080A11HDIFT4C30_V0-1](鑫洪泰)
- RGB interface (40p, 0.5 mm-pitch FPC connector), supporting up to RGB888 24-bit data transmission and up to 1280*800 resolution
    * Supported display models:
        * [IPS Version 7-inch RGB Display Module 1024*600 (ALIENTEK)](https://detail.tmall.com/item.htm?abbucket=17&id=609758563397&rn=b8068af8e33ece4aa2c043b54a77a153&spm=a1z10.5-b-s.w4011-24686329149.72.255354adb0S1oV)

### Audio Interface

The SF32LB58-DevKit-LCD development board supports:
- 1 onboard microphone input
- 2 audio ADC inputs (one is multiplexed with the onboard microphone and selected via a resistor jumper)
- 2 SPK outputs (support up to 3 W/4-ohm speakers)
- 1 PDM signal (multiplexed with the RGB signal and unavailable when the RGB display is operating)

<div align="center"> Audio Debug Wiring Diagram </div>   <br> <br> <br> 

 
### CAN interface

The SF32LB58-MOD module has a built-in CAN controller. The development board routes out a CAN interface, which requires an external CAN bus transceiver for use.

Refer to &emsp; [CAN Bus Transceiver Module](https://www.waveshare.net/shop/SN65HVD230-CAN-Board.htm)
