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]
In the project, CPLD is needed to complete part of the algorithm design. The parameters are given by AVR, so the communication between AVR and CPLD needs to be completed. Therefore, a test program is...[Details]
With the development of information technology, intelligence, informatization and networking have become the development trend of modern industrial control. Since the 1980s, the rapid development...[Details]
From the functional classification, it can be divided into: 1. Active control ADAS: ACC/AEB/LKS, etc. 2. Warning ADAS: FCW/LDW/PCW, etc. 3. Other auxiliary ADAS: BSD/ADB/panora...[Details]
Notes on inverter installation and maintenance:
1. Before installation, you should first check whether the inverter is damaged during transportation.
2. When selecting an installa...[Details]
Note: This STM32 microcontroller is the STM32F103 series. The ADC of Stm32 has DMA function. This is beyond doubt and is what we use most! However, if we want to sample a signal (such as a pulse sign...[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]
