What I am working on now is a digital display device, which uses a 12864 screen and an operating voltage between 4.5V and 5V. The circuit is very simple, controlled by a single-chip microcomputer and ...
Ladies and Gentlemen, this is my first time to use FPGA, and I am designing an image data acquisition system. The data collected by FPGA is transmitted to DSP for processing. DSP uses F28335, so the X...
I don't understand, is it the problem of the quarters version? The official ones are all 925 but the frequency division is biased. In addition, the system I compiled has this problem: 34.056675] mmcbl...
A potentiometer is needed in the production of a voltage-regulating power supply. However, the shaft of the purchased potentiometer is too large and the existing knob cannot fit on it. So I had to use...
I used assembly language to develop a F28035 project. When calling a function in an interrupt, a fault occurred after programming (it seemed to be running away). After eliminating the problem of savin...
