There are several reasons that may cause your problem. 1. The grayscale data of a pixel is actually 0-255. Is the data you encode encoded in the range of 0-255? 2. is it your data is code in byte insted of uint32_t or other thing else? 3. When writing to the memory of the display, is the data flow consistent with the data you encoded? 4. Whether the writing clock of the display screen used is correct? 5. Whether the display screen is matched with a suitable capacitor?
i suggest you buy a logic Digital Logic Analyzer to test your data stream into your screen.
有好几个原因可能会导致你这样的问题,1. 一个像素点灰度数据实际上就是0-255,你编码的数据是不是按0-255范围编码的。2. 你的字节流是不是按uint8_t编码的,而不是uint32_t或者其他 3. 当写入显示屏的内存时,数据流是否与你编码的数据一致。4. 使用的显示屏的写入时钟是否正确 5. 显示屏有没有搭配合适的电容
我建议你买个逻辑分析仪测一下你输入到显示屏的数据。

大佬你好,这个图片格式是通过什么方式转换来的?我用仓库里的这个图片demo_black_and_white.jpg,用image2lcd工具 水平扫描 单色 400*240 转换出来的是这样的:

哈哈哈哈哈 ,太久远了,我也忘了,应该是自己写的python脚本转的。不好意思,现在才搞定两步认证登上来回复
