The NTC on the expansion board is connected to the A0 interface of the development board, which corresponds to the PA3 pin, the ADC of the 8th channel.
This time we use the ADC_MultiChannelSingleConve...
First of all, I have to say that this board is very beautiful. Since there are relatively few external interfaces, and I am familiar with FPGA (ALTERA and XILINX) before, I didn't do any experiments a...
1. dBm dBm is a value that measures the absolute value of power, and the calculation formula is: 10lgP (power value/1mw). [Example 1] If the transmission power P is 1mw, it is 0dBm after conversion to...
1. I don't understand this point either. When SPIFFRX is initialized, bit12~8 (RXFFST) = 0, bit4~0 (RXFFIL) = 8. According to the documentation, a receive interrupt occurs when RXFFST >= RXFFIL, and d...
My graduation project is to design an aluminum can recycling device. I want to know what kind of sensor can identify and distinguish aluminum cans from tinplate cans? Different materials are detected ...
