Description

technical field [0001] The invention relates to the technical field of remote control, in particular to the technical field of learning remote control, in particular to a learning remote control circuit structure and a learning method with a built-in programmable memory for multiple times. Background technique [0002] Most of the existing technical solutions adopt an MCU (Micro Controller Unit, microcontroller) main control circuit and an EEPROM (Electrically Erasable Programmable Read-Only Memory, Electrically Erasable Read-Only Memory) circuit, and communicate through two IO ports; The learned button code data is stored in the EEPROM circuit, and then read from the EEPROM circuit to the main control circuit when sending the code; [0003] Another newer solution encapsulates the EEPROM circuit and the MCU main control circuit in the same plastic package, and the serial data communication port is connected together through a bonding wire to reduce the cost of the solution. ...
