I bought the micro2440sdk development board from Friendly Arm around July last year. I am now transferring it to you. I am willing to answer questions about bootloader and wince driver. I will also gi...
I seem to have found a solution in the previous post, but unfortunately, this problem occurred again, and the previous method did not work. This time, after clicking Query, the Programmer will crash a...
When I was reading the program, I suddenly found that volatile GPIO PA @ 0x5000; volatile GPIO PB @ 0x5005; What does the @ symbol mean? I would like to ask you experts! It would be better if you can ...

The two programs each have static variables or static areas. What is the difference between their static areas and the static areas of the operating system (where events and mutexes are stored)?...
1. Principle 1. Infrared emission protocol The infrared transmission protocol has been written in the previous article , so I will not repeat it here. 2. Timer counting and input capture A timer...[Details]
The day before yesterday, I learned about STM's Systick and found it quite useful for precise timing. When I used CVAVR before, I found that the delay.h in it was very useful. So, I used STM32's...[Details]

This is my first time writing an STM32 program. I have many questions to ask. I want to convert the data of the SO of MAX6675 into the actual temperature and read it out using the serial port tool. I...[Details]

The role of the watchdog: Since the operation of the microcontroller is often interfered by the external electromagnetic field, the program may run away and fall into an infinite loop. The normal ope...[Details]
STM32 has two watchdogs: independent watchdog and window watchdog. This article mainly introduces the use of independent watchdog. Independent watchdog (IDWG): driven by an independent 40KHZ low-sp...[Details]
How to convert the pin voltage value into V using the built-in ADC of STM32? V(ADC) = Value(ADC) * V(ref)/4096 (The ADC of STM32 is 12 bits, so the maximum value of the AD word is 4096)
Where V(ADC...[Details]
