CAN bus development board

Overview

The magnetometer data transmission system based on CAN bus adopts STC89C52RC microcontroller as the core for expansion design, combined with

The software program for CAN bus communication implements communication tasks such as receiving and sending data. To enhance the CAN bus

For anti-interference capability, the TX0 and RX0 pins of SJA1000 pass the high-speed optocoupler 6N137 with the CAN driver PCA82C250

TXD and RXD are connected to achieve electrical isolation between CAN nodes on the bus . In order to realize the communication between the magnetometer data transmission system and the computer,

The USB to serial port chip CH340C is used as the power supply circuit , and at the same time it realizes the transmission function of CAN bus to serial port data .

The debugging assistant can see the CAN data being transmitted.

Altium and other long-term design
When designing equal-length lines in Altium, if there are vias, because the lengths of the vias to different layers are different, will the via lengths be automatically added to the equal-length calcu
What is the difference between edge triggering (rising edge, falling edge) and level triggering (high level and low level) in digital circuits?
What is the difference between edge triggering (rising edge, falling edge) and level triggering (high level and low level) in digital circuits? Why do some have to use edge triggering and some have to
About adding components when making schematics in protel99se
When adding components to protel99se while making schematics, it always fails to add them and displays "File is not recognized". I searched online and everyone said that this software is not suitable
S3C6410 development board transfer
I have a S3c6410 development board. If you are interested, you can contact me on QQ 941012879. There is a Taobao link, which is exactly the same as this board [url]http://item.taobao.com/item.htm?spm=
Hello everyone, I am a novice and have some problems. I need your guidance.
I am using Quartus 11.0, which does not have simulation capabilities. When I call Modelsim, I can only perform Gata level simulation, but not RTL level simulation. I am very confused. What is going on
TM1804 DEMO
It is better to have more LEDs for running water lamps to make them feel better, so I add another string to make a total of 14 LEDs. TM1804 can be directly cascaded for expansion. The MCU uses a 1T 51
