I have already had several fake hardware engineer friends exposed by this question.
It is known that the initial voltages of capacitors C1, C2, and C3 are all 5V before K1 is closed. What are the pote...
V = 10/4095 * (( Code + 2048))0x00FFF) - 5The code is parsed in unsigned format, not in signed format. For example, if parsed in unsigned format, the sampling result is 2047 (7FFh) at 5V, 0 (0000h) or...
