In the past two weeks, I have used two ICs (PIC16 series and STM8S series) to make a product. It is my first time to use them and I encountered some problems. The summary is as follows: 1: PIC16 si...[Details]

There is a problem when using STM8 microcontrollers. If you want to use the second function of some pins, you need to set the option word. The option word can be set through code. However, it is trou...[Details]

Offset and gain errors (see Figure 7) are the most common errors in CV measurements. The X-axis gives the true value of the capacitor on a logarithmic scale, ranging from pico-farads to nano-fara...[Details]
