STMicroelectronics, a global semiconductor leader serving customers across the spectrum of electronics applications, and Fieldscale, an ST Authorized Partner and provider of simulation software, have joined forces to simplify development of touch-enabled user interfaces for smart devices containing ST's STM32 microcontrollers.
Touch-sensitive controls are convenient and attractive for end users, and can enhance product reliability, ingress protection, and cost-effectiveness. On the other hand, development can be challenging. Using a conventional iterative design approach, optimizing to eliminate unwanted effects and ensure consistent responses for touch sensing in all operating conditions can involve building multiple prototypes. For more information see the IDTechEx report on Printed, Organic and Flexible Electronics 2020-2030: Forecasts, Technologies, Markets.
ST and Fieldscale now enable STM32 customers to take a faster and more efficient route to market by introducing support for ST's Arm® Cortex®-based 32-bit microcontrollers to Fieldscale's SENSE development platform.
Fieldscale SENSE is an end-to-end solution for the design, schematic capture, and system-level simulation of capacitive touch sensors. The latest version lets STM32 users design the graphical appearance of the touch sensor and the PCB layout, and easily build a virtual system model for simulation.
The cloud-based development platform implements sophisticated electromagnetic algorithms which drives accurate prediction of the system performance. Users can optimize the design and quickly re-simulate to fine-tune the performance before committing to hardware. With greater assurance that first prototypes will deliver close to the desired performance, users can lower development costs and accelerate time to market.
"We are thrilled to partner with ST and work as an ST Authorized Partner.In Fieldscale, our goal is to offer to all capacitive-touch design engineers, a complete software solution supporting them end-to-end, from the early design up to the tuning of the final system. Integrating STM32 support is a major achievement towards this goal and we couldn't be more satisfied." said Yiorgos Bontzios, PhD, Fieldscale CEO and Co-Founder.
Patrice Hamard, Microcontroller Product Marketing Manager, STMicroelectronics, added, "Customers using our STM32 microcontrollers can now take full advantage of Fieldscale SENSE to implement simple and intuitive touch-based controls for smart devices and give their products a competitive edge."
Fieldscale SENSE is available now as an online service and comes with a flexible pricing model to meet your requirements/needs. Please contact Fieldscale for further information.
Further technical information:
As a cloud-based development platform accessed via an intuitive web interface, Fieldscale SENSE enables users to online evaluate their touch sensors using powerful proprietary field solvers and algorithms. Unlike conventional PC-based software, there are no installation challenges or system-performance limitations.
Fieldscale SENSE simulation results have been validated against measurements from actual touch-sensor manufacturers, confirming the results are accurate to within 2%.
Before committing to building physical prototypes, with Fieldscale SENSE users can:
- Design or import capacitive touch sensor layout as a standard DXF or Gerber file(s).
- Easily create the complete 3D model of the sensor by simply clicking their way through material and connections assignment. Fieldscale SENSE applies the appropriate boundary conditions automatically.
- Simulate the touch-sensor performance including the effects of using a stylus or wearing gloves.
- Add RF conducted noise into the system, to simulate the testing procedure as specified in the IEC61000-4-6 standard, to evaluate the noise immunity of your system
- Understand effects such as coupling between traces and electrodes that can interfere with the touch-sensor performance, to identify required modifications.
Fieldscale provides simulation software that helps IC makers and touch sensor manufacturers scale capacity, reduce product development cycles and go-to-market 10X faster. Using Fieldscale SENSE any engineer can make informed design decisions, starting from day one. For more information, go to www.fieldscale.com .
