Typical implementations of distance measurements use expensive rare-earth magnets. To lower overall system cost, this reference design walks through the implementation of industry’s first inductance-to-digital converters from TI for linear position sensing without the use of any expensive rare-earth magnets. Linear position sensing determines the position of a target that moves laterally across an inductive sensor that is generating a magnetic field. An inductance-to-digital converter (LDC), like the LDC1000 or LDC1101, senses inductance changes of an inductor that comes into proximity with a conductive target, such as a piece of metal. The LDC measures this inductance shift to provide information about the position of a conductive target over a sensor coil. The inductance shift is caused by eddy currents generated in the target due to the magnetic field of the sensor. These eddy currents generate a secondary magnetic field that opposes the sensor field, causing a shift in the observed inductance.

Описание:

Емкостные сенсорные дисплеи, как правило, представляют более высокое качество и большие возможности для пользователей, чем традиционные дисплеи с резистивной сенсорной панелью. Этот референс дизайн показывает, как подключить емкостной сенсорный дисплей к процессору Sitara AM437x. Дисплей имеет встроенный контроллер сенсорной панели, который подключается к AM437x по интерфейсу I2C.

 

Возможности:

  • Цветной 7-дюймовый TFT LCD дисплей с емкостной сенсорной панелью;
  • WVGA 800x480 разрешение пикселей с 24-битным RGB интерфейсом;
  • LCD интерфейс, подключенный к встроенному DSS (Display Sub-System) Sitara AM437x процессора;
  • Емкостная сенсорная панель подключена к процессору Sitara AM437x по интерфейсу I2C;
  • 27 белых светодиодов для подсветки, управляются ШИМ контроллером TPS61081;
  • Необходимое питание для ЖК-дисплея обеспечивается линейным стабилизатором  TPS65105;
  • Полная опорная подсистема с принципиальной схемой, BOM, проектные файлы и руководство пользователя.

Описание:
The Sitara AM437x simplified power sequence feature provides flexibility to power designers. This reference design implementation is a BOM-optimized discrete power solution for the AM437x processor with a minimal number of discrete ICs and basic feature set. The solution represents a baseline of a discrete power solution that can be extended for additional features and capabilities of the AM437x processor.

Возможности:

Simplified, BOM-optimized discrete power solution for the Sitara AM437x processor. AM437x includes an integrated LDO that simplifies processor power sequencing requirements. Systems without controlled power down can greatly benefit from this feature since the integrated LDO always ensures power up/down sequencing is met for VDDS and VDDSHVx supplies The TLV62565 step down converter provides the 3.3 volt supply and the TLV62080 provides the 1.1 volt supply. Two TLV702xx low drop out regulators (LDOs) provide the 1.5-V and 1.8-V supplies. TLV803M voltage supervisor keeps the processor in reset until all rails are operational and to reset the processor when input power is lost. This design is tested and includes schematics, BOM, design guide, and test data.

The Noise Tolerant Capacitive Touch HMI design (TIDM-CAPTOUCHEMCREF) is a reference design for implementing noise tolerant capacitive touch human-machine interfaces (HMIs). It integrates TI's MSP430FR2633 microcontroller (MCU) featuring high performance CapTIvate™ touch technology with the TPS7A4533 linear regulator and UCC28910 flyback switcher. This reference design demonstrates how to design hardware and software that can pass challenging system level tests for conducted RF immunity, electrical fast transient/burst immunity, and electrostatic discharge immunity by applying a three-sided design approach consisting of hardware design techniques, CapTIvate technology peripheral features and software signal processing.
Возможности:

MSP430™ MCU with CapTIvate™ touch technology for noise-tolerant capacitive touch sensing IEC 61000-4-6 conducted noise tolerance up to 10Vrms IEC 61000-4-4 electrical fast transient/burst tolerance up to ±4kV IEC 61000-4-2 electrostatic discharge tolerance up to ±8kV contact discharge and ±15kV air discharge Mutual and self capacitance sensing panels with universal AC and 12V DC power supplies for multiple test configurations
