Hi Vport,
Did you follow the guidance when you buil the library (https://github.com/andysworkshop/stm32plus/blob/master/INSTALL.md) ?

For me, I used Cygwin and build with no matter. Also success when I build with Eclipse IDE

You should post the details error screen snapshot to figure out the error

Dear all,
After we declare a can and use with below information for filter ability:
void initialise() {

      CAN_FilterInitTypeDef CANFilterInitStruct;


 Could you please show with me how to change these parameters in case we need?

Thanks so much

General discussion / Asus Z10PE-D16 WS 4101 BIOS mo...

I've recently been upgrading my PC from one based around the HP Z800 motherboard to a new one based on a pair of cheap Xeon E5-2678 v3 CPUs in an Asus Z10PE-D16 WS board. As part of that upgrade I've installed an Asrock Ultra Quad NVME PCIe card adapter. Like the equivalent Asus Hyper card this requires bifurcation of the PCIe slot which means splitting it from fixed x8 or x16 lanes to x4/x4 or x4/x4/x4/x4.

The Asus BIOS doesn't expose this option, but it is there if you load the BIOS into AMIBCP. I've done that, and made the option visible. The modified BIOS can be downloaded here:


I have confirmed that the option is now visible but as yet I only have one NVME drive on the Asrock card so I can't confirm if it actually takes effect when selected. I'm posting this here in the hope it's helpful for someone.

I flashed this BIOS by writing it to a USB drive and using the BIOS flashback option where you hold down the button on the back of board where the IOs are and boot the machine.

Quote from: hen6e on February 13, 2018, 07:04:53 pmAs I have learnt, the p1 connector pinout should be as shown,but I need your confirm.
The 10、1 Pin is output for 5V equipment like sata from VRMs on the motherboard.
The 16 pin is a POWER_GOOD signal,which trun to HIGH when the PSU finish startting period.
The 17 pin is a 5v stand_by voltage which is different from z420's 11V.
The 18 pin is a negative 12V input for RS232.
The 8 pin is PS_on,connect this pin to groung will trun on the PSU.
The 9 pin PSU_ID tells the motherboard which psu is installed ,it is different from standard ATX psu.
If you have oscilloscope or logic analyzer, please capture the waveform of PSU_ID.
Thank you!

I come from China
24pin -> 18pin
Is this correct?

Keeping it simple, can anyone provide me a complete bios dump from a z600 (rev3)? I am planning on replacing the bios chip (rev1) with the replacement bios (rev3) for that updated block date. please correct me if it is possible.

Have a progect that I don't know what to do with

I traded for a i7-6800k not realizing I needed a x99 Chipset so went on line and found a few blogs were they used a hp z440 motherboard even though it has a c612 chip set so I ordered it didn't realize it had a proprietary psu hook up but with so research and so passionce I moded my 1300 watt psu 20 pin motherboard connector to the motherboards 18 pin according to the diagrams I found and on the side in the 12 pin CPU memory power connector I placed an 8 pin and a 4 pin cpu connections put in my memory non ecc memory into slots 2 4 5 7 installed the cpu and my Vega 64 gpu and tried to boot but no sign of power double check the 18 pin connector with the multi meter and its correct

Compare the pinouts of the adaptor leads with the HP documents and ATX standard. I bought them leads and the PS_OK and 5Vsb pins were reversed. You should also disconnect the 5V between the motherboard and the power supply, that should not be connected. The motherboard generates it's own 5V and what the lead is doing is connecting that to the power supplies 5V output.
