Check if I belongs to dialout group (Linux command)

Tested on Linux Mint 21.2, to check if I belongs to any group, Linux command id and groups can be used.


id: Print user and group information for each specified USER, or (when USER omitted) for the current user.

id
id <user>

groups: Print group memberships for each USERNAME or, if no USERNAME is specified, for the current process (which may differ if the groups database has changed).

groups
groups <user>

boochow/MicroPython-ST7735 is a modified version of GuyCarver's ST7735.py ST7735 TFT LCD driver , for micropython-esp32. This video show steps to prepare boochow/MicroPython-ST7735 driver and font files. Tested on  Espressif ESP32-C3-DevKitM-1 running MicroPython v1.19.1, to display on  1.8 inch 128x160 ST7735 SPI TFT . Connection VCC 3V3 GND GND CS 4 RESET 5 A0 9 SDA 7 SCK 6 LED 3V3 Exercise graphicstest.py , modified to match our connection. from ST7735 import TFT from sysfont import sysfont from machine import SPI,Pin import time import math tft_CS = 4 tft_RESET=5 tft_A0=9 tft_SDA=7 tft_SCK=6 spi = SPI(1, baudrate=20000000, polarity=0, phase=0, miso=None) tft=TFT(spi,tft_A0,tft_RESET,tft_CS) tft.initr() tft.rgb(True) def testlines(color): tft.fill(TFT.BLACK) for x in range(0, tft.size()[0], 6): tft.line((0,0),(x, tft.size()[1] - 1), color) for y in range(0, tft.size()[1], 6): tft.line((0,0),(tf
