[North China Electric Power University] Simple amplification circuit tester

Overview

Press KEY1 to measure the first input voltage

Press the DIP switch on the left, press KEY1 again, measure the second input voltage, and measure the initial input impedance at the same time

Press KEY2 to measure the first output voltage

Press the DIP switch on the right and press KEY2 again to measure the second output voltage and at the same time measure the initial output impedance and amplification factor.

The OLED is connected to the PB6 and PB7 pins of the STM32FZET microcontroller to display the current Ui and Uo measurement values in real time. After detecting that Ui and Uo data exist, the amplification factor will be automatically calculated.

Ask a LoadString question
I saw a piece of code and I don't understand PBYTE pRes; pRes = (PBYTE)LoadString (hInst, IDS_DOITEXT , NULL, 0) // Get the length of the string resource int nLen = *(PWORD)(pRes-2) * sizeof (TCHAR);
