[b][font=微软雅黑][size=6]I have two idle ARM development boards (LM3S811), one of which is brand new and has not been opened yet, ready to be transferred. If you are interested, you can q me:) 821081701:...
Continuing from the previous post [url]https://bbs.eeworld.com.cn/thread-508526-1-1.html[/url] I saw the award ceremony for telling NI stories, but I didn’t win. I feel bitter, but I don’t say it. I q...
I recently made a NRF24L01 transceiver module controlled by LM3S8962. I transplanted the 51 code and many problems occurred. I couldn't find any related posts in the forum. Has anyone made this module...
Hello everyone, I am currently working on a three-phase PWM rectifier dual closed-loop control system controlled by DSP2812. When programming, I saw many people saying that the system should be normal...
I searched the Internet for a long time but couldn't find the 430 driver for the OLED screen. I had to spend an evening writing it myself. It has been written in the form of a header file. You can use...
