This is a display screen I made recently, made with LM3S9D92, and driven by SSD1963. Many source codes are referenced from zhengjiewen. I read many of his posts and learned a lot.But my screen has hor...
I wrote a program to sample AC voltage using AD. I found that the first sampled data after each program run is wrong. For example: The samples matrix is used to store the sampled result values. Sample...
Hi, I am a humble man, but I want to ask a simple question: To use the GPRS module to dial up to the Internet in Linux, do I only need the driver of the interface (such as the serial port) and not the...
The formation of slots in the PCB design process includes:Slots caused by the division of power or ground planes: When there are multiple different power supplies or grounds on a PCB, it is generally ...
I just started learning ARM. Can you share some experience? Thank you! For example, is IAR or ADS a better development environment? I think ADS is too complicated. I started with ARM7TDMI. Are assembl...
