Dear all,
I really need to talk to a ADT7470 fan controller.
All I need to do is read the RPM, and set the PWM speed manually.
There is no Arduino / AVR code available for this chip.
Is there a guide for making a custom library? Perhaps something for a similar chip?
Absolutely any help or pointers is greatly appreciated!
Many thanks,
Paul
Looks like a fun chip. As I made more I2C classes I can help develop a library. I have to go through the datasheet to see the details.
Q: if you connect the chip to an Arduino, can you see it with an I2C scanner?
Thank you very much for your kind offer to help!
As the package is so small, I ordered an adapter off ebay, waiting for it to arrive any day now.
Will post the results as soon as I will be able to connect it to my Arduino.
Thanks again!
Took some time this evening to try to make a lib, however it is quite an extended chip with a lot of functionality, got a first beta for a part the temperature functions. Not ready to share. It will take a few days to get a basic library, hope to do some FAN functions tomorrow (after work).
First BETA of the ADT7470 library, there is a lot not in the lib but it might just do the job.
Everything need to be verified if it works as this lib is pure written on the PDF.
See attachment.
Remarks and comments are welcome.
