Introduction

The BETFX module communicates with an external MCU via UART, with a physical format of 115200-N-8-1. F10 uses little-endian data stream transmission, allowing data interruption and retransmission. The protocol designates 0x54 and 0x55 as protocol keywords; any keyword appearing outside the SOF will be converted to the form 0x54 + N at the transport layer before transmission, and all keywords except the SOF will be restored at the receiving end. The frame structure consists of: SOF (0x55, designated as the SOF keyword; all keywords appearing in the application data are split into the form 0x54 + 1 by the transport layer, a process transparent to application-layer programming); ADDR (DE101 supports 4 device addresses, determined by the pin voltage of PA1 (Pin15) at power-up, defined as follows: AD1 < 0.5V: 0xA0, AD1 < 1.0V: 0xA1, AD1 < 1.5V: 0xA2, AD1 < 2.0V: 0xA3); INDEX (message number transmitted from 0 to 127; when the command is a write operation, DE101 sets bit7 of INDEX to 1 and returns it to the host; when the command is a non-write operation, INDEX is returned with its original value); LEN (data length of the PAYLOAD segment; a length of 0 is permitted, indicating a NOP FRAME; upon receiving each NOP FRAME, the slave...).
