As mentioned in my previous post CapSense Evaluation Kit - First Impressions, I planned to run through the user guide to familiarise myself with the board. I was particularly interested in understanding the configuration of the switch sensitivity and the SmartSense auto-tuning feature. I'd effectively run through parts 1 and 2 already so I returned at section 3 Kit Operation. I ran through the setup instructions 3.1 - 3.3 with no issues.   It's worth mentioning the kit features:   Fo ...
Intro The deadline for blog post submission is way too close to be ignored so let's get down to business. I've been lately busy with a lot of work-related stuff. All the hobby projects had to be put on hold. But since the summer vacation is getting closer, the calendar schedule for the people working at universities tend to show more free time slots. Here at Lodz University of Technology it's (luckily!) no different. The project The project I submitted for Wolfson Road Test has to do with the st ...
I volunteered for this road test because I thought that capacitive switches could be a good solution for front panels for CNC or measuring equipment in a workshop environment. I particularly liked the idea that you could design your switches on a PCB and then connect to a microcontroller via I2C with things like debouncing and calibration handled by the MBR3 chip. Alternativelty the GPO pins can be configured using to provide signals directly. This also means less wiring and no mechanical parts ...
