I have just started to learn embedded systems and I feel that the leap is huge. Some start with hardware design and use assembly and C to program a single-chip microcomputer. Some very complex hardwar...
I don't have any C language foundation. I learned microcontrollers by myself out of interest. According to the timing diagram of 1302 and my own understanding, I wrote the following program. Please he...
1. This is a discrete convolution algorithm. Since digital images are represented in the form of discrete pixels, the essence of digital image processing is the processing of discrete numbers.2. The s...
The TPS55340 is a monolithic synchronous switching regulator with integrated 5-A, 40-V power switch. It can be configured in several standard switching regulator topologies, including boost, SEPIC and...
I now need to fetch 16 data from sdram and store them in a 16-depth array, and then use the fourth number of the array as the basis for setting the working mode. The programming method is shown in the...
This program is written to simulate the serial port hardware mechanism. When used, a timed interrupt can be set with a time interval of 1/4 baud rate. The receiving function is called once for ea...[Details]
