Embodiment Construction
[0027] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.
[0028] Such as Figure 1 to Figure 4 As shown, a method for multiplexing connections between a microcontroller programming interface and a circuit board described in the present invention is carried out in the following steps; step 1, when the operation board needs to update the program, the operation board connection line 3 on the operation board 1 Choose to connect to the function adapter board 7 or the programmer 8; Step 2. When programming is required, pull out the operation board connection line 3 from the function adapter board 7 a...

The invention particularly relates to a microcontroller burning interface and circuit board connection multiplexing method. The method includes the steps that 1, when whether an operation panel needs program updating or not is judged, an operation panel connecting line on the operation panel is selectively connected to a function adapter plate or writer; 2, when burning is needed, the operation panel connecting line is pulled out of the function adapter plate and plugged into a burning port of the writer, and a microcontroller in the writer is in a burning state through a communication protocol; 3, program updating is carried out on a storage on the operation panel through the writer; 4, after program updating is completed, the operation panel connecting line (3) is connected to the function adapter plate (7) again, and after being powered on, the operation panel operates according to a new program. The method has the advantages that firmware updating of installed electric appliance product is simplified through multiplexing of the operation panel connecting line, and in addition, loss caused by large-scale assembly and disassembly due to firmware updating of the electric appliance is prevented.
Description
technical field [0001] The invention specifically relates to a connection multiplexing method between a microcontroller programming interface and a circuit board. Background technique [0002] In the stages of R&D, trial production and mass production of household appliances, due to design changes, design defects, changes in user needs, etc., it is necessary to reprogram the firmware of the microcontroller on the control board to update. [0003] The current common practice is to disassemble the whole household appliance, take out the control circuit board, and reprogram with the programming work fixture or the reserved separate programming interface. [0004] The firmware update of the current household appliances generally adopts the following methods: [0005] 1. Arrange the pads for programming on the control board. When the firmware update is required, completely remove the control board from the whole machine, place it on the special burning tool to complete the firmw...
