Format Arduino-Compatible Touch-Enabled Display Shield Delivers
5" Format Arduino-Compatible Touch-Enabled Display Shield Delivers Abundance of Added Value

Having already seen strong market uptake of the initial CleO smart display solution for rapid development of human machine interfaces, Bridgetek and FTDI are now expanding this product family to include a higher end version. Based on the widely-praised Embedded Video Engine technology, the new CleO50 shield has a larger 5.0” diagonal 800 × 480 pixel resolution TFT with built-in resistive touch screen, plus enhanced audio capabilities...

Versatile Voltage-to-Pulse Train Converter Supports Sensor
Versatile Voltage-to-Pulse Train Converter Supports Sensor Data I/O

When the need arises to convert voltage readings from an analog sensor into a pulse train, a low-end microcontroller offers a versatile solution. The design uses an 8-pin PIC12F683 to provide a pulse train that’s proportional to the sensed input voltage. This is useful, for example, when transforming a sensor signal into a format that’s compatible with a basic digital or GPIO input...

NXP Quadruples Computing Power for Automotive Radar to Enable New Range of Semi-Autonomous Capabilities

NXP Semiconductors announced a new automotive radar microcontroller, the NXP S32R27, that will deliver the features and performance required for making safe, automated driving a reality. NXP is the leading supplier of radar-based ADAS semiconductor solutions...

Fast-settling synchronous-PWM-DAC filter has almost no
Fast-settling synchronous-PWM-DAC filter has almost no ripple

An inexpensive way to implement high-resolution digital-to-analog conversion is to combine microcontroller-PWM outputs with precision analog-voltage references, CMOS switches, and analog filtering. However, PWM-DAC design presents a big design problem: How do you adequately suppress the large ac-ripple component inevitably present in the switch’s outputs?...
