I'm trying to read data from Infineons Tle493d_w2b6 sensor with an Arduino Mega2560. But their example code doesn't compile because of some error in a header file but i can't figure out how to fix it nor where the actual problem is.

Infineon provides a Arduino Library for their Tle493d_w2b6 sensor on GitHub (https://github.com/Infineon/TLE493D-3DMagnetic-Sensor). But when i try running their included Cartesian example it won't compile due to some problems in the "tle493d_w2b6_conf.h" file.

Cartesian example provided in Infineons Library:

#include <Tle493d_w2b6.h>

Tle493d_w2b6 Tle493dMagnetic3DSensor = Tle493d_w2b6();
void setup() {
  Serial.begin(9600);
  while (!Serial);
  Tle493dMagnetic3DSensor.begin();
  Tle493dMagnetic3DSensor.enableTemp();
}

void loop() {
  Tle493dMagnetic3DSensor.updateData();

  Serial.print(Tle493dMagnetic3DSensor.getX());
  Serial.print(" ; ");
  Serial.print(Tle493dMagnetic3DSensor.getY());
  Serial.print(" ; ");
  Serial.println(Tle493dMagnetic3DSensor.getZ());

  delay(500);
}

The lines that seem to be wrong in the tle493d_w2b6_conf.h ...

(These:

const RegMask_t regMasks[] = {

... all seem fine to me but somehow seem to be wrong.

Is there any obvious mistake i am making? Or any other library i can try to use?

Hello,

we purchased TLE493DW2B6A0 samples from digikey and built our system prototype.

everything works with multiple of TLE493DW2B6A0 sensors.  

the I2C address we used for TLE493DW2B6A0 is 0x6A / 0x6B.

now, we purchased TLE493DW2B6A1HTSA1  and used address 0x44 / 0x45 and it does not seems to work.

it seems to ignore the read/write command as if the address is not intended for it.

Can you please advise if there is anything else that we are missing besides setting the address to 0x44/0x45?

BTW, when driving to 0v on CLK and Data line, what is the minimum acceptable voltages?  is it 0.4v max?

our Output low Voltage is about 0.48v.  is it acceptable?

please see the attachment.

Thanks and Best Regards,

Henry

Hi

I am looking for a sensor that can measure the position of a flywheel of an engine.

Usually this is done with inductive sensors or hal sensors however my engine has 4 magnets on the flywheel so I think those would interfere with the signal I need.

The sensor would need to take over the ignition timing for my engine so I need one that is precise enough to do that..

I was thinking optical to measure teeth on the flywheel with one teeth grind out so it knows where the rotation starts/ends. Would this work for something like this? Rpm range would be up to 8000rpm and should work from standstill if possible for hand starting. Any help is echatrandom appreciated.
