Since China began to try to produce panels independently in 1998, in 2018, China's panel industry has gradually upgraded from a marginal industry to the largest production scale. Especially in the ...[Details]
I rewrote the main part of this program. The program uses the watchdog as a normal timer and scans the digital tubes in the watchdog interrupt. In addition, I added a display buffer. If you want to d...[Details]
STM32 uses FSMC to read and write CPLD programs. CPLD is hung on the address line and data line of STM32. CPLD is regarded as an off-chip RAM for reading and writing. On the board I made, CPLD is hun...[Details]
With the development of the automobile industry, more and more automotive electronic components are being used in modern cars, providing better safety, comfort and economy for cars. In the past, cars...[Details]
As shown in the figure, the author soldered a STM32F207VET6 board using a TQFP (32-100PIN) 0.55MM to direct plug adapter board. The board leads out the SWD debug interface (only PA13 and PA14 are occ...[Details]
The STM8L contains a 12-bit ADC with 25 input channels, including an internal temperature sensor, an internal reference voltage As can be seen from the figure above, there is an internal re...[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]
DMA： 1. When using DAC, when the converted analog signal is output through the IO port, why is the IO port also configured to input mode? PS: The stm32 manual defines that PA4 and PA5 are connected...[Details]
