What I did was to use S3C2410 to drive the ZLG500B card reader module to realize the card reading function. The communication between them is UART. Question: How to use C to write the interrupt initia...
For my graduation project, I am working on a CAN multi-point communication protocol using Freescale's DSP56F8037 (the main content is the transceiver program plus the upper-layer network protocol). Ho...
Now there are two dialogs opened, one is CMain, which is always open and will not close, and the other is CXXX, which is above CMain and is uncertain. When CXXX is opened, how to capture the messages ...
Photovoltaic inverters are the core equipment of photovoltaic systems. Their main function is to convert the direct current generated by photovoltaic modules into alternating current that meets the...[Details]
Event: The company simultaneously released its 2017 annual report and the first quarter report of 2018. In 2017, the company achieved revenue of 8.886 billion yuan, a year-on-year increase of 48.01...[Details]
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 status of interrupts in developing embedded systems is absolutely unquestionable. In the era of C51 microcontrollers, there were only 5 interrupts, including 2 external interrupts, 2 timer/counte...[Details]

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]
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]
This is a "cooperation" that is related to the future development of China's semiconductor industry. Let's follow the embedded editor to learn more about the relevant content.
Last week, a...[Details]
A crystal oscillator can be electrically equivalent to a two-terminal network consisting of a capacitor and a resistor in parallel and a capacitor in series. In electrical engineering, this network h...[Details]
Assume that the crystal frequency of the microcontroller is 6MHz. It is required to use timer 1 in mode 0 to generate a continuous square wave pulse with a period of 500us, and output it from P1.0. T...[Details]
Design a program for the 51 single-chip microcomputer. It is known that the crystal oscillator frequency of the 89C51 single-chip microcomputer is 12MHz, and it is required to use T1 timing to output...[Details]
Unfortunately, my serial port has some problems and I can't print information. I can only debug to view variables and see the values. Fortunately, there is not much AD conversion code, and I can use ...[Details]
