TangNano is the orignal board for GW1N-1 FPGA.
The new TangNano-1K is based on GW1NZ-1 FPGA, refer to: https://github.com/sipeed/TangNano-1K-examples
TangNano have shared 24M clk for FPGA, and 4MB SPI psram chip, use CH552 as programmer chip.
example include: RGB led RGB LCD
使用的是Tang Nano,最原始的那个，用到CH552做的下载接口，没有相关驱动，导致一直不能使用板子，想知道驱动的下载链接
Can you please explain how PixelCount can reach PixelForHS?
Could you please publish really working code?
Thank you!
Regards ~
The example_lcd sample does not seem to work because the PixelCount register is not incremented in example_lcd/lcd_pjt/src/VGAMod.v.
It worked by incrementing PixelCount.
I am trying to program the tang nano board via USB on linux, but the board doesn't enumerate.
Are there some solution for the problem?
lsusb doesn't return anything.
dmesg returns:
