In this example, the port name is /dev/tty.SLAB_USBtoUART. 2.3. Flash the Spresense board bootloader You need to flash the bootloader the first time you use Spresense. If you already flashed the bootloader to your Spresense board, you can skip ahead to Flash the CircuitPython image to...
The lineuart.write(b"h")writes the byte array string ofh(for humidity) to the Plant Monitor. If you are not getting responses, check your wiring. To read the Plant Monitor's response useuart.read(). In this case, you can see that the response message contains the humidity value of33...
Python UART Wiring If you wish to use UART, you can enable the UART mode by pulling the P1 pin high and connecting the sensor to your RX and TX pins: Pi 3V3 to sensor VIN (red wire) Pi GND to sensor GND (black wire) Pi TX to sensor SCL (yellow wire) Pi RX to sensor SDA (...
There's a hardware SPI port, hardware I2C port and hardware UART. Logic level is 3.3V Native USB, there's no need for a hardware USB to Serial converter as the Metro M0 has built in USB support. When used to act like a serial device, the USB interface can be used by any computer...

UART.write(...) no longer allows strings to be written. The bytes written must be bytes or bytearray or an array.array. framebufhas been removed.displayiois its replacement, and will be enhanced after 4.0 to includeframebuf's functionality. Thanks to@tannewt. ...
