Starting a new bioreactor

When you have a new bioreactor you should start by configuring it. You may connect using a terminal through the serial port.

You may as well use the Visual Studio Code (with PlatformIO extension) application to directly connect to the bioreactor through serial (press (Mac) ⌘+⇧+P or (PC/Linux) Ctrl+⇧+P and search for serial).

The menu is accessible using the h instruction.

important

If you can't open the serial monitor in VSCode with PlatformIO extension, please make sure that you have opened the project.

caution

You should not forget to add a CR + LF after each instruction, this is automatically in VScode Serial Monitor but you need to consider it if you don't have an answer in the serial monitor.

Initializing parameters​

Connect via the terminal and reset all the parameters to the default parameters:

ur1234

It is also important to set a unique qualifier for the bioreactor. You should fill the list with a free code.

Setup the weight​

There is now a special menu for the weight calibration w.

You should do the following step in order to callibrate the weight:

  1. Empty bioreactor : we
  2. Empty bioreactor + 1kg : wk
  3. Bioreactor filled at high level : wh

You may now check the reproducibility and the weight in g of any object using wt

It is important to note that an error (stored in PARAM_ERROR) will be generated if the weight is either 20% under the minimal value or 20% over the maximal value and this should stop all the functions.

The main parameters​

In order to activate the bioreactor you need to enable functions. Currently there are 3 functions:

  • Agitation (value 1)
  • Food control (value 2)
  • Temperature control (value 3)

You may enable the functionnablities by setting the parameter AZ. To activate all the functionnalities enter AZ63.
