Teensy 3.6? #10

Open abdoh747 opened 5 years ago

abdoh747 commented 5 years ago

Hi I am trying to use the library with a teensy3.6 and the BNO055 and it doesnt seem to be producing any output when I open the serial monitor. I am using pins 16 and 17 on the teensy which correspond to SDA0 and SCL0 but still no output.

I dont get any errors when uploading the BNO_055Nano_Basic_AHRS_t3 script to the teensy board, but

Any help is appreciated...Thanks

How are you connecting to 3V3 and GND? What is the voltage showing on SDA/SCL?

I connected the 3V3 to the pin between 12 and 24, and the GND to the pin just below pin13. The voltage on SDA and SCL is showing 3.28V.

kriswiner commented 5 years ago

then there is something wrong with the way your I2C functions. Can you read any I2C device on the I2C bus with a scan? Maybe you have thee BNO055 address worng...

I used this script: https://playground.arduino.cc/Main/I2cScanner and the board was detecting an i2c device on 0x28....

kriswiner commented 5 years ago

And are you using 0x28 to read BNO055 data? Can you read the WHO_AM_I register of the BNO055?

How can I do that?

kriswiner commented 5 years ago

Huh? What device address are you using to talk with the BNO055?

Sorry, but am a newbie... I am using a teensy 3.6 running arduino.

kriswiner commented 5 years ago

You don't know which I2C address you are using to send commands from yout Teensy 3.6 to your BNO055?

Better ask at the Teensy forum then...or read the I2C tutorial at Sparkfun

abdoh747 commented 5 years ago

Oh sorry, misread your email, The address is 0x28 which is what the i2C scanner showed but also what was expected i think...

kriswiner commented 5 years ago

Is this the address you are using in your sketch?

I am using the BNO_055Nano_Basic_AHRS_t3 sketch, which seems to be using it on line 167

kriswiner commented 5 years ago

Nope

define ADO 1

if ADO

define BNO055_ADDRESS 0x29 // Device address of BNO055 when ADO = 1
