When slave 1 sends data, Tx low level will pull down host Rx, while slave 2 Tx remains high level without affecting communication. It didn’t emphasize performance, it didn’t emphasize a thrilling driving experience, it didn’t emphasize sportiness. I should be clear by going directly to the block diagram: By modern standards, the Mark VIII’s layout was also unusual: a rear-wheel drive, V8 -powered luxury coupe that isn’t sporty, that doesn’t use a turbo engine, that isn’t anything but cushy or huge. Obviously, it can be solved by using one diode.

In connection, we know that only one serial port of raspberry pie is led out by pin, so I hope to control two stm32 boards at the same time through one serial port, so the idea of a master-slave custom serial communication protocol comes out.įirst of all, we need to solve the connection problem: we know that Rx and Tx of the serial ports of two devices need to be connected reversely when connecting, but a small problem needs to be solved when two slaves are connected: The Tx of two slaves are connected to each other, so that one slave cannot send data when it needs to send dataīy checking the data, we know that the serial port of mcu takes the low level as the effective value, so the problem is how to avoid the influence of the high level of Tx of slave 2 when the Tx of slave 1 becomes low.

The DDM also communicates with the driver seat module (DSM) to control the power mirror and seat memory functions. The DDM controls many functions including power windows, power door locks and remote keyless entry. Everyday low prices and free delivery on eligible orders. I will show them when I have a chance in the future The driver door module (DDM) is connected on the standard corporate protocol (SCP) communication network. Buy Serial Communication Protocols and Standards: RS232/485, UART/USART, SPI, USB, INSTEON, Wi-Fi and WiMAX (River Publishers Series in Communications) by Dawoud Shenouda Dawoud (author) (ISBN: 9788770221542) from Amazons Book Store. The latter two are boards made by myself with stm32f103rct6. In general, there are three main modules for communication in my Bi design: Raspberry pie as the main control board, sensor acquisition board and power drive board. As for why I didn't use modbus, it's just because I didn't use it. This article mainly records a communication protocol based on serial communication customized in Bi Shuli. This is a small record similar to the development log.
