设置SPI多个片选引脚除了config里面定义的其余引脚是否需要用GPIO虚拟,同时虚拟出来的引脚对传输速率是否有影响 可以使用GPIO模拟,在每次SPI发送之前,对SPI的片选信号也会进行控制,所以SPI的片选信号就是在每次需要发送到某个设备的时候,将CS片选端进行 ...
我当前MCU与TCAN4550双向CAN通信OK:上位机通过CAN调试器链接到TCAN4550连接至MCU,,MCU与CAN调试器双向CAN通信正常,能成功发送也能成功接收。但是MCU接收TCAN4550是通过中断查询的方式,在主循环中查询接收中断标志,如果有新消息,则能够成功读取消息。 目的 ...

I'm in need of a synchronous (for high efficiency) DC-DC buck converter with a 120V (max) input and 3V output. Is it possible to use TPS40041 where VDD is initially generated from 120V through a ...
I have a question related to security of F280049 device. Question is about when system needs to disable JTAG in the product version. I checked TRM and I found the below description. However, I would ...
Customer don't know how to calculate output data code. In the event of an input voltage overdrive, the digital outputs go to the appropriate full-scale level. For a positive overdrive, the output code ...
When customer doing short-circuit test, find the device will be damaged and gate pin has no output. It can be solved by add a 200ohm resistor in series on IN pin. Could you please help provide a ...
