I have just started using Linux and Arm and there are many things I don't understand. I hope you can give me some advice. What I want to know most now is which book is the best to get started with?...
The microcontroller controller I want to use is the STM32 series processor, the specific model is STM32F103VCT6. By understanding the information of the STM32 series microcontroller and comparing it w...
I have recently been studying the stm32L152 series of microcontrollers, using PVD to monitor the power supply voltage. When the voltage is lower than 2.9V, it enters the low-power stop mode. Now I can...
I need to convert the 5v power supply to 3.6v. I searched for a step-down IC but didn't find one. I only found one that is 3.3v. Now I use two 4007s in series and find that the voltage is 4.1v. The mi...
There is no "Enable Advanced Power Management" item in my mind. What is the reason and how to solve it? Before I came here to ask questions, I tried the following methods but they didn't work: 1. In t...
Emergency hand-held lamps powered by 6V maintenance-free batteries are widely used in rural areas. The charger used is a transformer step-down and single diode half-wave rectifier, and the charging...[Details]
Assume that data is read from 8-bit AD (if it is a higher-bit AD, the data type can be defined as int), the subroutine is get_ad();
