TiN Posted May 29, 2015 Share Posted May 29, 2015 (edited) 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.

Crew Trouffman Posted July 13, 2015 Crew Share Posted July 13, 2015 Any chance to compile this to run on the Odroid XU3 ? Shared Source code ? Quote Link to comment Share on other sites More sharing options...
buildzoid Posted July 14, 2015 Share Posted July 14, 2015 Any chances of doing this with an arduino? Quote Link to comment Share on other sites More sharing options...
Massman Posted July 15, 2015 Share Posted July 15, 2015 Yes, this is a relatively basic i2c communication. You can also use EVC. Any chance to compile this to run on the Odroid XU3 ? Shared Source code ? WiringPI is available for hardkernel: https://github.com/hardkernel/wiringPi Quote Link to comment Share on other sites More sharing options...
xxbassplayerxx Posted July 15, 2015 Share Posted July 15, 2015 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.

TiN Posted July 15, 2015 Author Share Posted July 15, 2015 Btw, it's not nvidia's to be precisely correct And I dislike arduino stuff regardless Pure C FTW! Quote Link to comment Share on other sites More sharing options...
RULE Posted July 15, 2015 Share Posted July 15, 2015 Hi Tin, is possible have a read out of the current? The CHL8318 should support this features, if i'm correct. Quote Link to comment Share on other sites More sharing options...

SimoFLC Posted December 25, 2015 Share Posted December 25, 2015 Hi,do i need EPower or i can use Raspberry straight to gpu? Quote Link to comment Share on other sites More sharing options...
buildzoid Posted December 25, 2015 Share Posted December 25, 2015 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? Quote Link to comment Share on other sites More sharing options...
SimoFLC Posted December 25, 2015 Share Posted December 25, 2015 thanks for answer, problem is find evbot, i tought was alternative way, but seems too difficoult for me Quote Link to comment Share on other sites More sharing options...
TiN Posted December 26, 2015 Author Share Posted December 26, 2015 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. Quote Link to comment Share on other sites More sharing options...

Where there is a TiN, there is a way! Quote Link to comment Share on other sites More sharing options...
