I couldn't stand the days without a screen, and the original plan was to make a GUI menu. The original board didn't have a screen, so I prepared a SPI-driven monochrome screen. When the board came out...
The video frame buffer with param IP provides a reference design. The default model in Gowin_VFB_PSRAM_RefDesign is GW2A. When I changed the model to GW1NR-9, the compiler prompted the error "ERROR (P...
Abstract: For the first time, a new idea of duty cycle extended high frequency pulse DC link inverter is proposed, and the working principle of the soft switching inverter and the three-state discrete...
Technology lies in accumulation! The first time I came into contact with LED drivers was from a DEMO board: DC input, the output is a low current of about 200MA; Due to customer needs, the company lat...
