433M Wireless Controller - Slave

Overview

I. Wireless Controller Communication Method
The 433M wireless controller (hereinafter referred to as the wireless switch) adopts a one-to-many communication method, that is, one master communicates with multiple slaves through polling. This control system supports a maximum of 20 slaves. The PC-side host computer software can configure and acquire the status of the slaves.

STM32 some information
[i=s] This post was last edited by Polaris405 on 2015-1-20 18:12 [/i] Some basic information about STM32. Beginners can take a look at it.
About Communications
I measured a square wave at pin 13 of 232, but a high level at pin 12. I have replaced 232 and the surrounding capacitors, but it still doesn't work. What's the reason? Both boards are like this.
Please teach me how to wind a small inductor
I recently used an LC filter, but I don't know how to wind a small inductor? Is there a technical formula or empirical formula that has been proven in practice?
LPC2388 chip program re-burning
I am now burning a chip program for LPC2388. After burning is completed, I found that it is not the program I want. Now there is no way to burn the chip again. Does anyone know a way? Please give me s
After copper plating, many width constraint errors occur
As the title says: Since the default grid width is 8mil, and the minimum line width of the check rule is set to 10mil, many errors occur. Should I change the minimum line width of the rule to 8mil, or
