I have a question: I customized a 28M system using wince5.0. My development board has 32M FLASH, 64M SDRAM, and 260M main frequency. I want to implement audio and video transmission, which has been im
Much has been written about how to terminate PCB trace characteristic impedance to avoid signal reflections. However, when to properly apply transmission line techniques is less clear. A proven guidel
Hey guys, I'm making a tool to test the consistency of a particle sensor. The main chip of the tool uses STM32F407. The MCU collects the data from the sensor and uploads it to the PC via USB. Labview
I would like to ask you seniors, STM32F103 SPI problem STM as slave (NXP's LPC2294 as host to communicate with it) (urgent) I encountered a problem in adjusting the SPI of STM32F103. I have been adjus
The AB32VG1 development board is equipped with a TF card slot, and its interface is shown in Figure 2. When a TF card is inserted, file-level operations can be performed with the cooperation of the fi
As shown in the figure, this is a commonly used charging circuit. The PMOS tube model used in Q411 is CJ3401, and the specifications are as shown in the figure. The working principle is that when 5V i
