I haven't been to the forum for a long time. Today I came to ask for your help. I have another problem and I need help from netizens. I use STM32F407 chip and SPI communication. Now the program is stu...
I recently went to a friend's house to help him move. My friend gave me a few JM38510/12908BPA to play with. When I went home and checked the specification, I had no idea what gate circuit chip it was...
I have seen some designs add matching resistors of around 50 ohms at memory interfaces such as SRAM and SDRAM.It can be seen as reducing overshoot and sitting phenomenon, but there are also many desig...
I have visited many forums and read many posts, but never replied to any of them. However, eeworld is the first place that makes me want to reply. So I decided to settle down here. Here are two small ...

Wireless Sensor Network (WSN) monitors the target by deploying a large number of sensor nodes in the target area. WSN realizes the positioning and tracking of the target, determi...[Details]
One in five car failures are caused by batteries, a problem that will become more serious in the coming years as electric-by-wire, start/stop engine management and hybrid (electric/gas) vehicles be...[Details]
DCDC means DC to DC (conversion of different DC power values). Anything that meets this definition can be called a DCDC converter. Specifically, it means converting the input DC into AC through a s...[Details]
This paper describes the design method of electronic multifunctional watt-hour meter, the key technology of hardware design and the software design process. Taking NEC's μPD78F0338 microcontroller ...[Details]
The principles to be followed are as follows:
(1) In terms of component layout, related components should be placed as close as possible. For example, clock generators, crystal oscillat...[Details]
Preface
DS18B2 is generally used in conjunction with a single-chip microcomputer, and there are few reports on
the interface between
