[size=6]Heroes, brothers, I refer to Zhou Gong's TinyM0 routine, why can't the UART project communicate, but ISP can program HEX files. I uploaded the project, please help me take a look. The question...
I have an ARM-7 development board with a CD that contains the 44b0test test program and a GPRS module. How can I modify the program so that I can send data to a specified IP via a serial port call GPR...
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...
UHF and HF are both general technology categories, but each category has independent supporting protocols. HF is more consistent in the 13.56MHz frequency band, although there are many internation...[Details]
Medicines are special commodities. If patients are given the wrong medicine, fake medicine, inferior medicine or expired medicine, it will pose a threat to people's health and lives.
In recent...[Details]
Many medical applications require portable, self-powered devices that do not require external power and data cables. The most obvious example is a portable data logger that patients carry with them to...[Details]
This summary will introduce the transmitter characteristic test of TD terminal products - uplink power control. According to the 3GPP TS34.122 standard, UE uplink power control is divided into uplink ...[Details]
