EmStat Pico MUX16

16 or 256 channel multiplexer with integrated EmStat Pico

  • Great for prototyping a multiplexed EmStat Pico potentiostat module
  • 16 individual or 256 combined channels
  • Controlled via MethodSCRIPTTM

Description

The EmStat Pico MUX16 is a developer board equipped with an EmStat Pico potentiostat module and a multiplexer and can be used in two modes:

  • MUX16 mode where the WE, RE and CE are all switched at the same time. This allows for 16 individual cells to be connected to the board, each with their own WE, RE and CE.
  • MUX256 mode where WE and RE+CE combined are switched separately, allowing 256 channels to be addressed as a matrix.

The multiplexer is controlled using 8 digital IO lines, this effectively creates an 8-bit address for the multiplexer. The 4 LSB bits of the multiplexer address switch the WE, the 4 MSB switch the RE and CE.

The embedded EmStat Pico is a proven, tested and calibrated potentiostat module which enables rapid prototyping, no programming skills are needed. With our free-to-use software PSTrace you can perform electrochemical measurements using your own electrochemical sensor. PSTrace generates MethodSCRIPT to easily reproduce your experiments on the EMstat Pico MUX16 as well as on our Market-Ready OEM instruments, or on your custom PCB. Our tested and calibrated modules are used by over 100+ OEM customers in over 30 countries.

Controlling the EmStat Pico MUX16 with your own code

PSTrace 5.8 does not support automatic switching of the EmStat Pico MUX16 in measurements or manual control. Instead, the EmStat Pico module works with the MethodSCRIPTTM language. The following example script can be used to set channel 2. 

e\n
#configure all 10 GPIO pins as outputs, add "i" to indicate it is an integer \n
set_gpio_cfg 0x3FFi 1\n
#Select WE2 and RE2/CE2\n
set_gpio 0x11i\n
\n
New line and comments in MethodSCRIPT
Note that \n represents a newline and '#' is used for comments.

For more information on how to control the EmStat Pico MUX16, please refer to the Getting Started with the EmStat Pico MUX16 document. This script can be sent through the PSTrace MethodSCRIPT Sandbox window or any terminal emulator. Many examples for using MethodSCRIPT on different platforms are available on GitHub.

Overview of software development tools

Software Development Kits for .NET

The PalmSens Software Development Kits (SDKs) for .NET can be used with any of our instruments or OEM potentiostat modules to develop your own software. The SDK’s come with a set of examples that shows how to use the libraries.

PalmSens SDKs with examples are available for the following .NET Frameworks:

  • WinForms
  • WPF
  • Xamarin (for Android)
  • UWP

SDKs for .NET

MethodSCRIPT™ communications protocol

The EmStat Pico potentiostat module has an on-board parser for the MethodSCRIPT scripting language. This language allows developers to program a human-readable script for the EmStat Pico module on any platform or operating system. The simple script language allows for running electrochemical techniques supported by EmStat Pico and makes it easy to combine different measurements and other tasks.
