My docker server on Pi journey

The idea is to have a Pi Zero 2W for experimenting with dockerization

  • standard RPi Bookworm installation, flashed on 16gb card with the RPi imager

SSH

  • ssh fails because maybe of the ip being alredy registered in ~/.ssh/known_hosts from an earlier installation
  • so I delete all entries there
  • still fails. turns out I forgot to check the ssh box during flashing

I2C on pin 8 and 9

When using the EXT 2.54-14P expansion bus with I2C in Bus Pirate, pin 8 and 9 although marked as SDA and SCL do not work as intended. I assume this is related to being used with the keyboard and the BMI270 on another bus I switched to pins 40 and 14 (above 8 and 9 on the expansion bus) and it works fine

font size in Standalone Terminal Mode

standard font size is very small, tried to fix this

  • installed platform.io extension in VS Code, cloned https://github.com/geo-tp/ESP32-Bus-Pirate.git to local
  • setTextSizein /src/views/CardputerTerminalView.ccp to 1.5 at four positions
  • works but rows are overflowing
  • set charW = 9; charH = 18; in CardputerTerminalView::recomputeMetrics() which worked but now the line heigth does not fit any more so keep `charH = 12
