Hi, I am aware of the specifications for the pinouts of fans what I don't know is how to read the Signal from the motherboard that tells the fan what to do, I have no idea what the signal looks like and no idea how to interface that signal to the Arduino, I have seen a circuit for reading the...
All I need to know in this instance is what the motherboard is feeding out to the fan as a measurement and what the fan is reporting as it's speed as a measurement, that is all, once I know that I am sure I can figure the rest out.
Re: Desperate for help or this could cost me a huge amount of $$$
Well it while it solves the problem, it doesn't point in any way to what the problem is which is what I am trying to figure out.
I am in desperate need of help, I have an extremely expensive motherboard and CPU, I think there may be a fault in the systems bios that has not been fixed yet but I think it may have already killed an AMD Threadripper 2950X.
{Edited should have mentioned the Fan is four wire Noctua NF-A15PWM...
And I think that this - rev 4 will be the final version unless someone else can see some circuitry that is doubled up.
There may be one or possibly even two replicated circuits in there but if there are I can't see them, being able to print it out would be an advantage for doing manual gate...
I have loads of 9572XL's and have been needing a Binary to Hexadecimal 7 Segment decoder. There used to be loads of these devices but now they are like hens teeth, I haven't yet tried this out in one of my CPLD's but the logic has been tested and it works.
You set the binary values by loading...
Hi Klaus, I can provide a schematic for all of what I am talking about barring the micro but as I don't know which micro has the correct number of pins for what I am wanting to do I would just have to fake one until I know what to use is that still appropriate?
Possibly complex question from someone who still does not have a full understanding of AVR/Pic pin name definitions.
I have managed to figure out that PIC's etc have ports A,B,C etc and that those port have direction registers etc and related pins but...
I am looking at making a charlie plexed...
It is entirely possible it is static ram. I have two other sets of 24 pin wide body IC's - with completely different numbering which are Async CMOS 2048W x 8 Bit Static Ram, I may have to do some testing with them, it's not like I haven't got enough of them as I have 887 units so blowing up a...
Thanks I'll have a look, I have a few tubes of these that were given to me and I could not find a manufacturer with H barring hitachi which has been brought by renasys. ( however that name is spelt - I get it wrong every time I try ).
It's a 24 Pin wider body DIP, I thought it might be by Hitachi but then realized this an H is not their symbol.
I'm trying to figure out who it's manufacturer is as well as it's purpose.
Thanks in advance.
Help needed ppwith LED's from somone with a very simplistic knowledge of electronics.
I am a tech support person - not someone with a lot of knowledge when it comes to electronics, I have been asked to hook up LED indicators that monitor the Raid Controller on a companies LSI-9361-8i and I...
