Note

Error code:RP2017

When you meet error code PR2017, just enable corresponding IO as regular IO.

Click Project in top menu bar and choose Configuration, then enable the corresponding Dual Purpose Pin to deal with this error.

Lite-bottom_test_project

This is the test project which is used for testing Lite-bottom and core board(Factory test). Including the DDR-Test project and another demo containing all other usable IO blink.

DDR-Test

Thanks ZiyangYE providing this example. Using serial-communication with 115200 baudrates to shows result.

SPI_lcd

This is an example driving 1.14 inch spi screen.

RGB_lcd

Screen datasheet: Click me

Cross colorbar on the screen.

480x272_4.3inch_lcd	800x480_5inch_lcd

Colorbar on screen

rgb_lcd_4.3inch_colorbar	rgb_lcd_5inch_colorbar

Cam2lcd

There are 4 projects, their name rules are as followings:

Folder name	Camera	Screen resolution	Frame storge mode
OV5640_LCD480_DDR3	OV5640	480x272	DDR3
OV5640_LCD800_DDR3	OV5640	800x480	DDR3
OV5640_LCD480_FIFO	OV5640	480x272	FIFO
OV5640_LCD800_FIFO	OV5640	800x480	FIFO

These are only for testing, and if you want better results, you need program on yourself.

After burning the .fs bitstream into fpga, press S0 button to reset fpga chip to get right display.

Micarray

There is demo for micarray board.

rocket

This runs a rv32ic rocket core with a UART peripheral attached. This example system outputs A via UART infinitely.

WS2812

A demo for onboard ws2812 led.

USB

Demo for onboard USB3317 Hi-Speed USB Transceive based on LUNA.

UART

A demo of UART, set baudrate and open the onboard COM port to see the message.

Tang Primer 20K Dock pin constrain

Clk pin

The clock pin on primer 20K is H11

Reset pin

The reset pin on primer 20K is T10
