通过比较,介绍了一种具有同步串行外设接口(SPI)特点的8 位新 型LED显示控制驱动器——PS7219,介绍了其芯片,描述了与单片机及发光二极管的硬件连 接。指出用此显示器可克服以前常出现的干扰、显示错码、显示闪烁等问题。
By comparison, a novel 8-bit LED display control driver with synchronous serial peripheral interface (SPI) is introduced, which is called PS7219. Its chip is described, which describes the hardware connection with MCU and LED. Pointed out that the monitor can be used to overcome the interference often appear before, display error code, display flashing and other issues.
