Sometimes I want to check out the posts I participated in before, but it’s not easy to find them! I can just add this function to the bottom of my posts. I wonder if the website has considered this as...
Recently, the project needs to use mqtt on stm32. I searched on Baidu and found that there is still very little information on the Internet, although there are several relevant materials. After downlo...
[b][size=4]Recently, a new project has started. I worked overtime for 7 days during the National Day holiday. I sent out the boards I had drawn before. In order to save money, I put together 6 boards....
I was reading the IIC section in Professor Xia Yuwen's book, which describes how the data on the SDA data line is stored in the register. The data is valid when SCL is at a high level (that is, SDA mu...
1: I am using C6424, which is in little-endian mode. I saw that the CCS configuration platform can be set to big-endian mode, so I set it to big-endian mode, and everything can be compiled. Finally, w...
Does anyone have a small signal model for buck dual-loop control? The outer loop voltage loop, the inner loop current loop, and the average current model?...
