Lecture 1: Mainly explains the basic concepts of CPLD system development, introduces the respective characteristics of CPLD and FPGA, their manufacturers and corresponding software as well as developm...
About viper50 I recently used viper50 to make a 16.8V2A constant current and constant voltage power supply. The constant current and constant voltage functions are good, and the voltage can be stabili...
Platform: S3C2440 + WINCE5.0 The driver uses interrupts EINT0 and EINT5, and there is an interrupt every 20ms. After the interrupt comes, 300Bytes of data is read from 3 GPIO lines in IST. The test fo...

Hello everyone: I have been studying the knowledge of driver design of DM642 recently. In the process, I encountered some problems. There is one problem that I can't figure out! According to the infor...
1. Problem When developing STM32 with IAR, I found that I could not print floating point numbers by redirecting printf to the serial port. The code is as follows: The output is as follows: It can...[Details]
Recently, the " ZTE

Independent watchdog (IWDG) and low power mode are often used in STM32 development. The watchdog is to detect and solve faults caused by software errors, and the low power mode is to enter sleep mode...[Details]
The STM32 watchdog has two WWDG and IWDG. The biggest difference between the two is that IWDG has only one lower limit for feeding, while WWDG, as the name implies, must be fed within a range to ensu...[Details]
STM32 ADC multi-channel conversion Description: Use ADC to continuously collect 11 analog signals and transfer them to memory through DMA. ADC is configured to scan and continuously convert mode,...[Details]
Here is the temperature added in the previous chapter The above figure is the temperature calculation formula: where Vsense is the ADC value collected from the temperature channel. The stm32f407 ...[Details]
1) ADC multi-channel acquisition: (Multi-channel acquisition must use scanning mode. In scanning mode, the channels of the rule group share a register, so DMA transmission must be used; to prevent da...[Details]
