Please help me analyze the operation of this circuit.There should be a sine wave output on the left side of R2, but I can't see it in the simulation. I don't know what the problem is....
This is mainly used to debug the G2452 RTC chip I made a while ago. I didn't have any ready-made tools, so I came up with this solution. I also learned about the USCI UART module by the way. In the en...
Under WINCE, I want to complete the CAN bus communication function by calling WIN32 functions, that is, get the handle of CAN1 through CreateFile(), and then perform send and receive operations by cal...
I have a device made with STM32F103VC. I used to use injection mode (all three ADs were used). The sampling zero drift was very small, basically within 1 LSB (most of them were 0). Now I use DMA mode ...
After writing the address to 430, the power is turned off, and then the power is turned on again, a small part of the address will change. What's going on? ? ? ?...
