In the project, we used the EA DOGM1602W-A display screen, which uses st7036 as its core. After initializing the screen according to the manual, we found that the contrast was too high and the charact...
I came to the company to work overtime today with great interest. I want to get the development environment of this programming model. I had all kinds of problems with it on Mac at home before?
Do I n...
Hello everyone, if I want to speed up the booting of WINCE5.0 XIP, MULTIBIN is XIPKERNEL.BIN and DRIVERS.BIN, etc., right? If I download XIP.NB0, will it only load a small part into the memory to spee...
I have had the honor to experience other boards of Mil before. This is a brand new experience. It is the first time to test the domestic Allwinner platform. In fact, Allwinner, a domestic brand, has m...
