A fix is to set register 0xF4 to 1 which would send the writes to the shadow SRAM, instead of the EEPROM. A fix for this is to connect an external raspberry pi to the I2C External pins and reset the registers. |

 ## Todo
 - [ ] Verify that the node register values are valid.
 - [ ] Create install and uninstall scripts and/or deb package.
-- [ ] Move `nodes.cfg` to `/etc/turing-pi-scripts/` directory.
