I tried the serial port terminal of ART-PI today, and found that using the serial port can send shell commands to the board. This may be his operating system! It's not very clear yet, and then explore what is going on with this operating system? Successfully drive the OLED display. The example found on the Internet seems to be wrong. Pressing his does not work. I fiddled with it and found it. The OLED display is too low and may not be suitable for this board. I plan to buy an RGB display. On Taobao, it’s almost two hundred dollars. Qunyou plans to offer a second-hand display. The total of OV6070 camera, shipping, and adapter board is about 150. Although it is not very cheap, they have already done it on ART. Tested, it works normally, he doesn’t give the code, he still has to study it himself
