Simple Python tools for the Raspberry Pi embedded in the SuperBIT Data Recovery System

DRS_Python_Tools

Simple Python tools to control the Data Recovery System:

• DRS_tx_off.py pulls the Pi's serial Tx pin low to prevent it from supplying parasitic power to the SAMD processor. This will run automatically on boot if added to /etc/profile.
• DRS_on.py will set the GPIO pins to enable the latching relay and provide power to the SAMD processor. The code also restores the serial Tx pin to alt5 mode.
• DRS_log_serial.py runs for 5 seconds and appends any incoming serial data to DRS_serial_log.txt. You can then tail the log file to see if the GNSS receiver has established a fix.
• DRS_GoGoGo.py sends the GoGoGo command to the SAMD processor. Confirm with y or Y.
