When debugging the USART of STM32F103,after initialization of USART1, the data is sent normally in a while (1) loop. After changing the initialization configuration of USART1 to USART2, including the ...
Use CS2, the bit width is 8bit, the addresses of the 4 digital tubes are: 0, 1, 2, 3 CS is configured to GPCM mode. What does it mean to use cs2 when making a digital tube driver for an mpc8313 develo...
I just came into contact with single-chip microcomputers and digital tubes. My four-bit common anode digital tube driver circuit is shown in the figure. It uses a triode [img]data:image/png;base64,iVB...
I recently wanted to use uc3842 to make a step-down circuit that can achieve 24V--5V. I will not consider the specific ripple requirements, power consumption, and efficiency. I have consulted some inf...
In order to prevent traffic accidents, when the intelligent detection device of the car detects danger ahead, it must send a warning message to the driver. The voice alarm clearly reminds the drive...[Details]
