The invention provides a DMA-based SPI communication method, comprising steps: after the processor is powered on, the SPI interface is initialized; the processor initializes the receiving and sending configuration of the DMA; When the data to be sent is reached, the DMA is started to send the data to be sent in parallel. When the data to be sent is sent, the DMA generates a transmission completion interrupt; the main program of the processor loops to detect the SPI interface. When the main program of the processor detects the data to be received, Start the DMA to receive the data to be received in parallel, and when the data to be received has been received, the DMA generates a receive completion interrupt. The invention relates to electronic equipment and a readable storage medium for executing the above method; the invention also relates to a DMA-based SPI communication device. The invention adopts the DMA technology and the interrupt generated by the DMA, so that the main program of the processor can quickly take and process the data in the interrupt service program, and obviously reduce the time resources occupied by the single-chip microcomputer.

The invention belongs to the technical field of edge trimming of lithium batteries, in particular to an edge trimming device for lithium battery production and a method thereof. The operation of the existing edge trimmer is complicated, and the lithium battery needs to be held by hand during operation, and the distance between the hand and the edge of the cutter is too close , there are potential safety hazards, and it is not convenient to fix the lithium battery. The following scheme is proposed, which includes the console. There are two knives, a vacuum cleaner is installed under the operating table, a cutting table is installed on the top of the operating table, and a lithium battery is placed on the cutting table. On both sides, the top of the cutting table is provided with a vertical plate, and a pressure plate is slidingly installed on one side of the vertical plate. The invention is easy to operate, convenient to fix the lithium battery, avoids stabilizing the lithium battery by hand, and can stay away from the cutter to avoid potential safety hazards.

The invention relates to a quick assembly type tent.
