In order to solve the common problems of engineers, Texas Instruments launched the world's first wireless MCU CC1350 that supports both 2.4GHz and Sub-1GHz dual-bands. It integrates multiple IoT wirel
The design of eCall in automotive applications is still relatively complicated for many engineers. Today, let’s talk about how to design enhanced eCall cars more simply and share some RF design expert
Debugging two boards STM32 SPI DMA master-slave communication, the master is STM32F107 SPI3 DMA2 channel 2. The master sends the clock and MOSI waveforms normally. The slave stm32f103 SPI2 DMA1 channe
Some time ago, I saw several netizens encountering problems when doing I2C. I recently took some time to learn. Here are some places in the routine that are prone to errors. #define I2C_SLAVE_ADDR 0x5
For single-chip microcomputers, GPIO is often used. Here, an oscilloscope is used to test the IO flip rate to see how fast it is.
The manual gives some characteristics of GPIODirectly flip GPIO progra
1. In the newly created PCB, press the "O"-"O" (Option-color) shortcut key to set the color of each layer of the PCB: Three principles for setting layer color: ① Close to nature and looks comfortable;
