The aim of this project is to understand the Tecan wire protocol so we can control the robot using a python app.
Source code will be here https://github.com/london-biohackers/python-tecan-genesis
Aims of the project are
connect to the machine over serial from python (hardware handshake etc)
$ python tecan_stuffs.py The Tecan Reports FIRMWARE version: AYM1@GENESIS-V1.61-07/2001A
initialize the machine
This requires to send the firmware command to the Roma "PIA" position initialization, and then send "PIS" to the main initialization
$ python tecan_stuffs.py init Initialization complete
- read the current position of the Liha (liquid handling module and tips)
- this is kinda working.
- read the current position of the Roma
- this is kinda working.
control the Lihi- this is kinda working.
control the RoMa- this is kinda working.
- handle collision condition from robot
We used portmon to dump the data from the serial port
