Support for GIGA R1 WiFi with 3 x I2C
Closed this issue · 3 comments
Hi, been using your library successfully on a Mega (thankyou) but I'm now migrating to a GIGA and would like to use Wire1 rather than Wire. I notice other mpu6050 libs have the interface as an argument. Is that possible currently (maybe with a local hack) with your lib? If not, any plans to do this as I'd like to stick with this lib.
Thanks, Steve
Hi @megacct !
Sorry for the late reply. We really appreciate your support in this library and you bringing this to our attention.
At the moment there is no a “simple” way to set the library to use Wire1 instead of Wire as you mentioned. Nevertheless, there is a local hack and I just tested it out.
Here are the changes I made to make it work with the GIGA.
- Locate the relevant files:
- Go to the library folder. This is usually located at C:\Users<username>\Documents\Arduino\libraries.
- Locate the Electronic Cats MPU6050 library folder. This is usually named MPU6050.
- Open the
I2Cdev.cppfile in your preferred text editor. I recommend you Visual Studio Code to perform the following steps more effectively.
- Modify the code
- Search for instances where Wire is used directly.
- Replace those instances with a variable that can hold either Wire or Wire1 based on the chosen argument, or you can directly replace it Wire with Wire1. What I did is to use the find and replace function of Visual Studio Code to first find all the
Wire.definitions and the change them toWire1.this way I avoided changing the library Wire definition. - Replace the instances Wire to Wire1 in the Arduino sketch you are using.
- Test with Arduino GIGA.
I have tested this with the DMP6 example and the GIGA is able to communicate with the sensor and work with it. I will share this feedback with my colleagues since it would be great to find an easier way to implement this.
Hope it works for you. Let us know if there are any other questions.
