The physical object has been verified to prove that the design of the interface between CPLD and MCU is completely correct. MCU and CPLD are highly complementary: MCU has irreplaceable advantages in t...
I have been using CCS for a while, but my machine was too bad (a 2006 laptop), and it took nearly 2 minutes to start debugging in CCS. …… :funk: So I switched to IAR5.10, and the speed has indeed incr...
I want to know the manufacturer of Nokia's built-in camera, for example, what is the model of the built-in camera of Nokia 3220? Manufacturer, and how to obtain the detailed datasheet of these mature ...
A small project I'm working on recently requires saving AD sampling data to EEPROM. The requirements are: 8-bit AD, 5k sampling rate (tentative, may be higher), sampling for 10s, that is, 50,000 bytes...
Recently, the first Digital China Summit was held in Fuzhou, attracting many domestic ICT industry giants to participate in the exhibition. The long queues outside the venue, the noisy and exciting...[Details]

Function List and Notes (lower-level driver part) 1. IO port initialization: control IO and communication IO. Control includes power control, reset and low power mode. Communication is the serial po...[Details]
introduction In the general project development process, two or more microcontrollers are often required to communicate to complete data transmission. For example, a quadcopter wirelessly transmits d...[Details]
The implementation of CAN driver under embedded operating system Android requires not only adding CAN driver device in Linux kernel, but also implementing the call of Android HAL layer. Taking S5...[Details]
Using the WWDG of STM32F030, it is found that the MCU will not be reset under STOP, just like the sleep mode of STM8S. Paste the watchdog code: /******************************************************...[Details]
1. Function and purpose There are two pins BOOT0 and BOOT1 on each STM32 chip. The level status of these two pins when the chip is reset determines which area the program starts from after th...[Details]
Summary of STM32 peripheral DMA usage: 1. Select DAM mode according to your needs: (1) Circular mode—DMA_Mode = DMA_Mode_Circular (2) Normal mode—DMA_Mode = DMA_Mode_Normal 2. For Chanel3 of DMA1, t...[Details]
1. What is PWM What is PWM? Professionally speaking, it is pulse width modulation. In layman's terms, it is the continuous output of high and low levels. For example, the microcontroller outputs...[Details]
Using AT89S51 microcontroller, modify the original one to turn the LED on for 4s and off for 2s. Thank you. Use a timer. (The program is written in the answer, omitted here - just a note) The origi...[Details]
Requirements: Set timer T1 as an external event counter, count 500 pulses every time, then switch T1 to timing mode and output a positive pulse with a width of 10ms at P1.2. Over and over again. A...[Details]
