MSP430 MCUs featuring CapTIvate technology are the most noise-immune capacitive touch MCUs, and first to feature an IEC61000-4-6 certified solution. These MCUs feature the most configurable combination of buttons, wheels, sliders and proximity sensing interfaces, as well as support for metal touch, glove-proof and moisture-tolerant designs, all at the world's lowest power.
This training series details the key features of MSP430 MCUs featuring CapTIvate technology, enabling you to get started on your next great capacitive touch design and get to market more quickly.
This training series covers LEA or Low Energy Accelerator a vector math co-processor, the performance benchmark, and how to get started on the new MSP430FR599x. LEA is capable of performing various signal processing tasks efficiently without any CPU intervention. For example, LEA can perform a 256-point complex FFT in just ~5k cycles whereas a Cortex-M4F would take approximately 17k cycles (3.6x improvement).
Delta-sigma analog-to-digital converters (ADCs) are oversampling converters typically used in applications requiring higher resolution. However, ADCs do not work by themselves. In fact, they require several key components around them, including a front-end amplifier, a voltage reference, a clock source, power supplies, and a good layout. Many devices integrate these features together with the ADC to offer a complete system solution, which simplifies the design for customers and minimizes board space.
This training covers the fundamental design techniques required to implement a successful capacitive sensing hardware design. This series will explore a number of design topics, including: Basic layout guidelines overlays, back lighting; Dealing with moisture; Self capacitance sensors; Mutual capacitance sensors; and Proximity sensors.
These videos provide understanding of the fundamental functions used for rapid prototyping on TI solutions with minimal or no programming, including the following:
- Implementing necessary prototyping functions such clocks/GPIO, Read A/D, I2C/SMBus, etc.
- Seamless interface of various analog EVMs for customer “proof of concept”
- Standalone UI – Button, (GP Input - GPIO), LCD Display (“Hello”), Music, Serial Interface (Putty, Echo)
How many times have you said, “I would like to prototype an idea with TI silicon but I can not get software resources" or “I don’t know how to prototype/program.”
This training shows you how to get started prototyping on TI solutions with minimal or no programming, including the following tasks:
For anti-tampering, it is common to try to detect the presence of a strong magnet. In this section, we will cover the use of hall sensors for low-power detection of strong magnetic fields in three dimensions. Details on our magnetic tamper detection reference design, TIDA-00839, will be provided as well as some of the design considerations that were kept in mind when creating this reference design.
In this section, we will cover how to harden a meter against these magnetic tamper attacks by using shunts for current sensors. For poly-phase implementations, I will go over how to use isolated delta sigma modulators to add the necessary isolation to use shunt current sensors and create magnetically immune poly-phase energy measurement systems. The TIDA-00601 and TIDA-01094 reference designs, which show how to implement a poly-phase isolated shunt measurement system, will be discussed as well as the associated AMC1304 high-side power supplies used in these designs.
