Hi
I use the INT1 for data ready interrupt,But the I2C bus always become to busy error.And if unuse data ready interrupt, the error was not occur.
When the error occured, the I2C SDA was low . and the INT1 was did not reset to nomal mode.
Think for anybody help me.
Hi Sun,
First off, can you please confirm that you are using our 3-axis gyroscope FXAS21002?
Then to better understand where the problem might be, could you post here your source code and oscilloscope plots illustrating what is going on on the I2C bus? How many slave devices do you have on the bus?
I would also recommend you to look at our example project with the FXAS21000.
Best regards,
Tomas
Hi Tomas:
First off, can you please confirm that you are using our 3-axis gyroscope FXAS21002?
→yes,I am sure。
How many slave devices do you have on the bus?
→Only one: FXAS 21002。
I2C CLK frequency is 381KHz, I confirmed using an oscilloscope。
Timing is all Satisfy in addition to tf,tf is 2.2ns。But I think it not the reason 。
Could there have been no similar problems?
