stm32plus C++ library / Setting up a project without a...
Last post by simon - October 29, 2019, 04:16:47 am
Hello

So, looking into stm32plus for a quick project I'm cooking up using one of the "Baite" Maple Mini clone boards (STM32F103c8t6, 64k or 128k ROM, 20K RAM, 72mHz).  It seems I should be able to use the f1Hd setup and simply avoid the hardware I don't have, perfectly happy with that, and edit the link script to suit the RAM and ROM I have available.

Where I get stuck, though, is that I don't like IDEs in the slightest (I'm an old and grumpy unix dev from the days when even line editors were considered unnecessary frippery), and have never previously used scons.  Do you have any ideas on how to get started setting up a project *without* any of the IDE jazz?  I'm guessing this involves setting up all sorts of magical Sconstruct files?

Thanks for any advice you might be able to give

Hardware projects / Z600 Bootblock
Last post by joe_zeroh - October 01, 2019, 07:07:10 am
Hello everyone,

while trying to install a pair X5675 in my old Z600 Workstation the Bios refused to boot. A single X5675 boots fine. According to the HP Quickspecs this processor should be supported. Currently, i assume it is related to my the old bootblock of my Z600 mainboard. I have managed to read the Bios EEPROM with CH341A by de-soldering the Vcc Pin as suggested in other threads for the Z800. By comparing this image to the image contained in the Bios update, i could see that several pages at the beginning of Bios update image just contained 0xFFs, so it is missing the bootblock.

So my questions is: has anyone in this forum with a Z600 Rev003 the possibility to dump the EEPROM and send me the image? Also hints where else i could find this image would be very welcome.

Best regards, Joe

Yes, SMD connectors (micro or mini) are a separate issue. I agree and only use ones with through hole connections.

Also, re: the crystal, it IS a tuning fork. See:

The other day I unplugged my GP and the USB charging connector came out  Is this a repairable item? Is there a way to by-pass the missing connector and charge the battery another way??

Help

Oh
Thank you Very much.

However I had a spare Supply.

Maybe I should say a supply that was not in use, it was purchased for my 3DP11 that had never installed.
My first 3DP11 is working perfectly well with the Original power supply a 12v 30a 360wt.

Though I do appreciate the offer.

that code looks to be using 0x3f as the address. Have you tried the code you found with MICROSOFTWAY defined to use the NETMF libraries or are you just using the software I2C? Regards,Mark

Oh Really important The ICSP header on the dev board is NOT the standard Microchip pin out. Youll need to know how to wire a cable.

Hi, I think you may run out of inputs on a single LTC2986. I would recommend downloading the evaluation software from the analog.com site and running the configuration designer to see if what you're planning is feasible.


I'll have to wait until later when I'm near my dev computer.  Maybe a simple question, but are both of the K-type wires needing to be connected to individual channels? ...or can one side of each of the 6 K sensors be tied to one channel?   With RTD's I've tied on side of those to 5v and then measured each separately on the 328p.
