WebSep 16, 2024 · In this project, you’ll learn how to communicate between two different CircuitPython boards using UART. UART, universal asynchronous receiver-transmitter, is a serial communication protocol that works asynchronously. Unlike I2C, it isn’t structured and does not require pull-ups. WebYou can only access USB Serial Adapters using pyserial (i.e., USB RS-232 dongles). If you want generic USB access you should be looking into "libusb". If it is RS-232 you are trying to access through USB then you should look for a file in /dev starting with cu.usb* (/dev/cu.usbserial-181 for example).
