use i2c scanner issue.. about ambpro2_arduino HOT 18 CLOSED

Reminder everyone, if using pin 12.13, please change Wire1. begin() to Wire. begin(), and you will find that it is working properly

Dear @Oliver0804 ,
Thanks for reporting this issue.
I have verified that AMB82-MINI does not support examples such as "I2C - Scan I2C devices" nor "I2C - Display Data on LCD_Screen" at this point of time, we will update you again upon deploying the bug fix.

Hi @Oliver0804 ，

Example will be provided on v4.0.6 early release (dev branch) V4.0.6-QC-V01, lower level including HAL and ROM code have been modified, thus we need to update the archive libraries as well.

The glance of the code can be found below:
Open the example in “File” -> “Examples” -> “AmebaWire” -> “I2C_Scanner”.

When the I2C bus detect any I2C device, the serial monitor will show the address of the I2C device as shown below:

 
When there is no I2C device connected to the board, the Arduino IDE serial monitor will show the message below:

Thanks

Thank you. After I updated the library functions at the same time, the problem was resolved

from ambpro2_arduino.

I have also used the 'wire' from the Ameba2 mini examples, and verified with an oscilloscope that there is no output change in every GPIOs pin.

This issue is stale because it has been open for 14 days with no activity.

It has been tested and the problem still exists. When no i2c device is mounted, a pile of addresses will still be scanned

from ambpro2_arduino.

I used amb82 for testing

@Tomi-ren,
Glad that your issue has been solved.

@Tomi-ren, Glad that your issue has been solved.

But I tried multiple i2C devices, but the amb82mini couldn't scan their addresses and kept saying "No I2C devices found". On the contrary, using Arduino Uno to run the scan example made it easy to scan the devices, which I find difficult to understand

from ambpro2_arduino.

@Tomi-ren,
Sorry that since it's the development branch, while I was doing the commit, I didn't change from Wire1 to Wire and it might cause potential confusing.
Anyway, glad that you have solved your problem, this will be fixed in the final master branch release, and I will proceed to close this issue.
Thanks

I will wait for it to be merged into the release version before I proceed with testing.
and I think the problem won't be considered resolved until the official version is released.

This is very good, i2c support has been a real issue with using this board for any projects.
