12/17/2022 0 Comments How to use serial port in raspberry piA lot of people are looking online for the Raspberry Pi serial communication python method. When one does the placement of the Serial Expansion HAT on the Raspberry Pi serial port that it needs to be programmed for the task. The user needs to give the power to serial expansion HAT by the power cable to start it. One needs to connect the serial expansion HAT with the Raspberry Pi 4 serial ports or any Raspberry Pi variants that would enable multiple devices to connect with a single Raspberry Pi. Serial expansion HAT is a revolutionary product that assists the user to connect multiple serial devices with single Raspberry Pi that helped the user to modify the assemble. One of the common questions that come from the user is “How to connect multiple serial devices to Raspberry Pi?” that became a problem from the start of the Raspberry Pi. Steps To Connect Multiple Serial Devices To Raspberry Pi Work position - There are multi LEDs that are connected onboard for indicating the position of work of UART which makes the user understand the status of the device.It would enable the user to stack the devices that enhance the efficiency of the task. Easy stacking - It is arranged together up to 16 of these modules by setting the address jumper A0 and A1 that would make 32-ch UART.I2C - There is an onboard SC16IS752 that expands UART of 2-channels and 8 GPIO, programmable, through I2C. Connectivity - Raspberry Pi connectivity with standard 40 pin GPIO header, compatible with all the Raspberry Pi variants Zero/Zero W/Zero WH/2B/3B/3B+/4B.Many people use the serial ports for the serial communication between two Raspberry Pi but for the multiple connections, Serial expansion HAT performs the system with higher efficiency. Raspberry Pi Organization designed the device Raspberry Pi with only a UART port to transmit and receive data over serial communication. Serial Expansion HAT developed to avoid this problem from the usage of Raspberry Pi multiple UART devices that makes the transmission possible to more than one device. It becomes impossible for a user to plug in two or more devices simultaneously with the Raspberry Pi.
