As I write more and more stm32plus code I thought it might help people if I share small snippets of code to do common tasks in the spirit of the github gist. Feel free to contribute snippets yourself and/or comment on others.

Do you know some low cost mainboard with 4 CPU sockets for Xeon X5680?

I find out Supermicro X7QC3, but it still too much expensive.

About 2 CPU slots, did you take a look at Dell Poweredge R410 ? It has a low cost at eBay (lesser than Z800).

Hi Andy,
How are you, I hope fine.
I finished my project, but I decided to use TI DP83848 RMII instead instead of Micrel KSZ8081, see here:

You Oven Reflow project is very interesting.
I will try to replicate your reflow project and will let you know if it worked at 110V.
BR,
Alan

Hello, not sure if this topic has already been discussed before, but has anyone attempted to get correct ambient temperature readings so far ? It seems that the HP zx00 and xwxx00 (at least some) workstations read the ambient temperature via a sensor connected to pins 11-13 of the main connector. The sensor is embedded into the power cable assembly, at least for the xw8600 and similars (P/N: 349576-006). Here [1] is reported an equivalent schematic to build your own sensing circuit. It seems that the air temp sensor drives the speed at which the front fans spin, at least on xwxx00 workstation: getting correct temp readings should slow em without fancontrol. Another option would be getting a xw8600 cable and using the sensor contained therein.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

BTW If people are looking for easy to install aftermarket CPU coolers, the coolermaster hyper t4 requires no modification. The screws go directly in the current plate for the CPU. I will be posting picture of my rig soon.

Hi Guys,
turns out it was the psu. I RMAed it for a evga 1.3kw supernova g2. It starts up and recognises both processors.
void SysTick_Handler() __attribute__ ((weak, alias ("Default_Handler")));
extern void SysTick_Handler();
Quote from: yaqwsx on June 26, 2015, 03:25:59 amTo be clear: I am trying to use your library with GNU toolchain using Visual Studio and VisualGDB plugin, so I setup the project from scratch. It is possible, that I have ommited some steps necessary for the aliases to work. I attach the configuration of the project (the startup code and linker script are generated by VisualGDB).
/*
* SysTick_Handler in stm32plus is now marked 'weak' so that compatibility with other
* frameworks is made possible.
.weak SysTick_Handler
.thumb_set SysTick_Handler,Default_Handler
*/

Hello,
I am also trying to use your great-looking library for STM32F103C8. I tried to use the F1_HD settings with linker script from VisualGDB. The blink example hangs in Default_Handler. It seems like no handlers were defined - when I look inside the g_pfnVectors, all vectors have defined Default_Handler.
Could you please take a look at it?

So I got my rig up and running with windows 10 technical preview, dual xeon x5550, a gtx 295 and 24gb ram. My problem now is that hyperthreading isnt working. I have it enabled in the bios but it doesnt work when I am in the OS. If anyone has any advice it would be much appreciated. If not I will try and install windows 7 on one of the other hard drives to see if it is a problem with the OS. Thanks.
