Using Raspberry Pi instead of EVBOT to adjust EPOWER's.

Recommended Posts

Well, since EVBOT having transition state currently, here's alternative solution for you, EPOWER people.

Since controller accepts controls from PMBus, attached Raspberry Pi can talk to EPOWER and adjust voltages. Voltage range is 0.6 to 2.0V

 

Tested with Model B Rev2.0 (not plus), but should work with any Pi.

 

Details in this article for those who interested.

Try it, and let me know if any problem :)

 

Also old-school hardware-only way with trimpot resistor is covered too. :rolleyes:

 

:D

I asked TiN the same thing over at KPC and he said it would be possible to do it but he cannot release NVidia's voltage tables for Arduino since they wouldn't be compiled in .exe form and would essentially be out in the open.

Btw, it's not nvidia's to be precisely correct :)

And I dislike arduino stuff regardless :D Pure C FTW!

Hi Tin, is possible have a read out of the current? The CHL8318 should support this features, if i'm correct.

Hi,do i need EPower or i can use Raspberry straight to gpu?

 

This whole thing is about using the RPi to control the E-power. What do you want to hook the RPi to?

Here I showed example of using RPI directly to VGA to control voltages.

So yes, you can directly control VGA, if you know what to send to control voltages/settings on I2C.

:D Where there is a TiN, there is a way!
