Pressure Sensors

Our XENSIV™ family of digital absolute barometric pressure sensors gives designers the best choice when it comes to mobile and wearable devices. Highlights include small form factors to facilitate system integration, highest precision and relative accuracy over a wide temperature range, fast read-out speeds via the serial I2C/SPI interface, and low power consumption to ensure longer battery lifetimes. All of our air sensing solutions have a FIFO buffer that can store the last 32 measurements. Since the host processor can remain in sleep mode for a longer period between readouts, the FIFO buffer can reduce system power consumption further.

Speed (Magnetic sensor)

In this forum you can post your questions, comments and feedback about the XENSIV™ Speed sensors. This sensor family is based on integrated Magneto Resistive (ixMR) or hall-based technologies in order to determine linear and rotational speed. Our Speed sensors can be used with ferromagnetic gear tooth wheels or encoders to measure speed and position and they are essential components for the function of safety and powertrain applications like rotating shafts. Here you can also find the links to the latest board pages, documents and FAQs.

I have dual TLV493D sensors I've been trying to get working. I've used multiple configurations

MSP430 + TLV493D on perfboard
ATMEGA (3.3V) + TLV493 on custom PCB
XMC1100 2go + TLV493 on 2nd custom PCB

In each implementation I can get either of the two sensors to work on either of the two addresses but when I try to run the two concurrently one or the other addresses throw a NAK

2774.attach

My most recent code is attached (using the Arduino IDE 1.0.3 board/libraries front-end provided by Infineon 😞

#include 
#define SECONDARY_PIN 5               // P0.15

void setup() {
  Serial.begin(9600);
  while(!Serial);
  
  delay(2000);
  Serial.println("Initialization...");
  delay(500);
  
  pinMode(SECONDARY_PIN, OUTPUT);     // Sensor #2 Power Pin
  digitalWrite(SECONDARY_PIN, LOW);   // Force Sensor #2 off

  Serial.println("Starting Sensor #1");
  magnetic3dSensor_primary.begin();
  delay(100);

  Serial.println("Starting Sensor #2");
  digitalWrite(SECONDARY_PIN, HIGH);
  delay(10);
  magnetic3dSensor_secondary.begin();

  Serial.println("Setup complete");
}

void loop() {
  magnetic3dSensor_primary.updateData();
  delay(100);
  magnetic3dSensor_secondary.updateData();
  delay(100);

}

I assume I have tunnel vision now if you folks can get me out of the tunnel I'd appreciate it.

Thanks much and have a great weekend!
