1. Last year, the process operating system RTthread was still very popular. Here, the fans are accelerating innovation and launching new concepts. How about combining arm-m4 and FPGA? Take a look at t...
I just saw a fun thing online, called a sun jar. The principle is very simple. Get a solar panel to charge a NiMH battery, then use a photoresistor to detect the external light, and turn on the LED wh...
I have only been in contact with Zigbee for a short time, but I want to use Zigbee to collect some temperature, humidity, smoke and infrared data. Here, three nodes and a coordinator are used. A probl...
I used to use stm32f103, but now I need to use LM3S8962. I have a TI evaluation board, but I can't download the program using MDK, so I use IAR instead. Since I don't have an IAR project, it's very tr...
