At this point, capacitive touch technology is interspersed everywhere. Increasingly, we see it in places like electronic door locks, home appliances, video doorbells, and all sorts of control panels. But the thing with capacitive touch tech is that, you know, it obviously needs to work, right? We all know how frustrating it is trying to click on a touchscreen when the “touch” part isn’t operating properly.
Thankfully, TI has the solution. The Texas Instruments EVM430-CAPMINI is an evaluation board designed for the MSP430FR2512, which is a 16-bit capacitive touch MCU that comes with 8 KB of FRAM, another 2 KB of SRAM, and a 10-bit analog-to-digital converter.
Now, the EVM430 eval board itself also features four capacitive touch buttons that allow both single and multiple touch, LEDs that light up to indicate a touch event, and an onboard speaker for audio output and an integrated HID serial communications bridge for CapTIvate Design Center to PC communication.
CapTIvate Design Center is a GUI designed by TI to be a “one-stop resource” for their capacitive sensing MSP430 MCUs. This drag-and-drop style interface enables you to set up designs in just a few minutes, as well as create, configure, and tune capacitive sensors like the buttons on this guy without having to write any code yourself. When your design is fully created and tuned, CapTIvate Design center will generate the source code you need for each element that can then be transferred into code composer studioTM or IAR Embedded Work Bench® IDEs.
With the CapTIvate Design Center, you’ll also receive access to the CapTIvate Software Library, which includes loads of tools and software components to help with things like hardware abstraction, electromagnetic compatibility, sensor processing, etc.
You can purchase your own EVM430-CAPMINI evaluation board from Digi-Key for $20.73, or directly from TI for just $11.99. Of course, if you’d rather not spend the money, you can also enter the raffle linked above for a chance to win this board right here for free.
