Hi, I just connected a "3D Hall 2 Click" module to a 3.3v arduino pro and appear to have i2c communication but all I receive is the value "0".
"X = 0.00 mT; Y = 0.00 mT; Z = 0.00 mT; Amount = 0.00 mT; Azimuth = 0.00 mT; Polar = 0.00 mT; Temp = -346.50 mT"

I'm using the Tlv493d-a1b6 library. version 1.0.3

and the "cartesian" example sketch.

Can anyone point out where I'm going wrong?

Thanks. Show Less

I am using STM32F303x microcontroller to established the communication with the TLE493D-W2B6 A0.
I made the reset commands as said in the manual (Start -> 0xFF -> Stop -> Start -> 0xFF -> Stop -> Start -> 0x00 -> Stop -> Start -> 0x00 -> Stop), and tried configuring the registers 0x10, 0x11 and 0x13.



I received acknowledgement from the sensor, thus confirming the correct usage of address. Also, I was able to turn ON/OFF the INT mode of the sensor, by changing the bits in 0x11 (MOD1) register.



Having said that, I was not able to read any register values and even if I read, it is giving me plain 0xFF (255) and nothing else. For example, once I configured the registers, I requested for 20 bytes (0x16 is the last register). I got 0xFF in response (20 times). This included the registers that I configured with different values. Each time I receive with an ACK from the sensor, confirming the communication being established.




I tried a working code (arduino) for the magnetic sensor with an Arduino Micro, and the result was same. The sensor that I used with arduino and STM32 are different but the results are quiet the same. I wasn't even able to read out the value from version register.

I even looked into your official GitHub library - https://github.com/Infineon/TLE493D-3DMagnetic-Sensor - where users commented about similar issue (reading 0xFF).

The configuration values that I used for each register are as follows (STM32)

0x10 - CONFIG - 0x10 (no trigger bits), 0x01 (parity bit set).
0x11 - MOD1 - 0x11 (no trigger bits), 0x85 ( Two Byte Master Mode with Clock stretching enabled and INT disabled and parity bit set).
0x13 - MOD2 - 0x13 ( no trigger bits), 0x40 (update rate of 24Hz).

I would like to add that I have tried other configuration settings -

- With and Without Parity bits (Config and MOD1)
- 2-byte and 1-byte mode
- Low power mode and Master mode
- INT enabled and disabled
- Different update rate

I will be glad to provide more information, if required. Thank you. Show Less

We were previously using your TLV493d sensor and had that working fine but the power consumption was too high for our needs, therefore, we are trying to move to the TLE493d with the Wake Up functionality.
It took a while to find the correct I2C sensor address of 0x22 but now I can finally talk to the sensor.
However, when taking readings from the senor it is sending a response of 0xFF for all registers.

I have tried using 2-byte read (supposed default) as well as 1-byte read just in case.

I really need to have this working as soon as possible so any help would be greatly appreciated!

Thank you. Show Less

I read data from tlv493 via i2c bus with xilinx fpga spartan6.
the setting procedure is:
for low power mode:
1. write data (0x00 0x80 0x00 0x60) to address 0xBC;
2. write data (0x00 0x85 0x00 0x60) to address 0xBC;

for fast mode:
1. write data (0x00 0x80 0x00 0x60) to address 0xBC;
2. write data (0x00 0x86 0x00 0x60) to address 0xBC;

After mode set， int is produced according power mode， it works well, then I read data follow INT signal after 12us.

For the data read from sensor, Bx is right all the time，but By and Bz and Temp is wrong sometimes，when it is wrong, the register 2 to 6 are 0xff.

The other question is that in low power mode FRAM COUNTER is not increment all the time, It even depends on magnetic field intensity, sometimes normal, sometimes abnormal.

I am totally confused!

Hi,

Although this question was asked previously by a member in this forum but no one in this forum explain the solution of it.

So, i am posting it again so that this type of configuration can be understand clearly.

The Question is:

Is TLE493D able to detect both 3D joystick position and angle rotation at a same application with only one chip and same magnet magnetization?

More specific, one joystick is placed above the sensor. When the joystick is moved to a certain position, then it is rotated. So in this application, could TLE493D be used as implementation of joystick position and angle check at the same time?

If not than what configuration can be used to achieve this type of application.

I hope the expert in this forum will be able to explain this:

Thanks in advanced.

regards,

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



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!
