I encountered a low-power operational amplifier MCP6002 when designing a circuit. The reference circuit uses a square wave power supply. Is there any reason for this?
Through the schematic diagram, we know that the control chip of OLED is SSD1309, which is connected to SPI1 interface. According to the source code, we can also see that SPI bus is also used. So we us

In the previous article, we introduced the hardware schematic diagram of the AC7801x motor development board. Now let’s complete the construction of the development environment.
First, we come to the
