Experimental device based on STC MCU (micro controller unit) teaching

The utility model discloses an experimental device based on STC MCU (micro controller unit) teaching. The experimental device based on the STC MCU teaching is applied to the field of MCU teaching, and comprises an STC MCU, a power circuit, an oscillating circuit and a reset circuit, a man machine conversation channel configuration unit, a forward channel configuration unit, a backward channel configuration unit and a mutual channel configuration unit. The experimental device based on the STC MCU teaching uses the MCU to function as a core controller, is capable of being used for teaching traditional 80C51 MCU and other relevant contents, further enables students to learn novel function of mainstream MCU, and is beneficial for transitional learning of students from traditional 8051 MCU to the novel mainstream MCU.
