Hi
This may be unrelated - have you just installed the latest build 1903 ? of windows 10
at work this has also broken Autodesk Inventor 2018 & Autocad 2018. We have rolled back to the previous build

So might not be a bug in FC8 - MS could have caused this

Hi Bob

Hi Martin

thank you wow ... that's a pretty hefty document

http://www.thefullwiki.org/IEEE_754-2008

after a quick look I am going about it incorrectly,

Steve

Hi Martin, What I don't under stand is how do I get from : my 4 bytes of data : 0x43 0x6D 0x05 0x1F So looking at data stream - this should be 237.02 hex to decimal 43 = 67 6D = 109 05 = 5 1F = 31 so if I simply add those together as first thought = 212 another example I found was to convert the num...

Hi Martin,

sorry i didn't understand it, could you explain how it works and what is happening please
I dont have an adrunio either to try and use.

Steve

hi Martin

Thank you for that i will have a look later

Steve

Morning All, Bit stuck again can somebody explain how to convert Float – Big Endian (ABCD) to Decimal please ? I would like to understand how 43 6D 05 1F = 237.02 And 42 48 0F 5C = 50.015 i found something on the visual studio pages saying to read the bytes one at a time and reverse them. I cannot g...

Hi Derrihj Have you tried a google search "microchip inverter reference design" https://www.google.com/search?q=microchip+inverter+reference+design&oq=microschip+invert&aqs=chrome.2.69i57j0l5.12373j0j8&sourceid=chrome&ie=UTF-8 they are quite well documented and contain lots of information Steve

Evening All Received a pair of these boards and have a few questions. I am presuming that they have an entry under V7 as a device ? Where are they located as i cannot seam to find them. Do i need the Itanium drivers again that i use for the ECIO's (ex server as pc) The VB programs that are in the ex...

Hi all, Another zero crossing here if you are interested. https://www.matrixtsl.com/mmforums/viewtopic.php?f=54&t=16363&hilit=zero+crossing#p67589 PS there are pics that do have zero crossing detection built in. Just a suggestion dont want to confuse the issue. why not use DC and a fet ? and PWM - t...

Sorry Jan I misread your post -

Thought you where going past the standard length of cable supplied with the programmer

need new glasses I think ..

Steve

Hi Jan, Don't believe this is a V8 issue I experienced this with V6 as soon as you try to go past the supplied lead length with ICSP Programming you get all sorts of weird results and miss programming. Have even tried twisted pairs and screen cables. Ended up sticking with the supplied lead. There i...

Re the V7 Wiki - USB Application Guide https://www.matrixtsl.com/wikiv7/index.php?title=USB_Application_Guide Looking to learn more about USB interfaces and flow code, When I click in the example to download them I get a message "you do not have permission to modify this page" ? Looking for tutorial...

is your power supply stable under load ? 45 volt 20 Amps is quite a lump

Steve

Hi Martin

Thank for that very interesting read

Steve

Hi All I am in need of some advice / assistance if you can help me out. I have been given a "Project" and its a bit out of my comfort zone TBH but suppose thats the way to push my self and chance to learn new things and get back into flowcode. We have an old load bank that has an RS232 Port we are w...

Afternoon All After mooching around RS for some parts had a go with their part selector found a couple of suitable devices had another go with MPAS these parts didn't appear Have found the following devices - so will order them and have a go. 4 PWM channels too and supported by V7 :mrgreen: PIC16F18...

Hi Mate,

I remember that post too .. but thought it was a PS2 one ? not USB

Is this it ..

:edit, just thinking are you wanting to make a keyboard or read a keyboard ?

Hi Ben Might be a few weeks before i can get back to you mega busy at work at the moment :( Why do you say only 1 timer ? was thinking on the lines of timer2 for the PWM frequency timer0 for the duty or is this OTT and heading on the lines of generating a headache ? looking for a 0 - 240 count where...

Afternoon All, Looking at an application that I would like 3 PWM channels my device only has two available only a cursory look on microchips part selector reviled that 4 channels tend to be on the high pin count devices. So thought of doing it in software have seen the software PWW example of a nigh...

Thanks guys I think I will give it a go to be honest was a bit put off with kicad as I read that eagle users tend to struggle as they are used to the qwerks of eagle. Watched a you tube on library loader and was quiet impressed with it. After speaking with the pheonix contact rep today he told me qu...

Cheers martin

Will look into those - Library Loader looks interesting do you use that ?
I noticed on there you tube video that they use Design Spark didn't know that could do 3D now
Can i ask what you are using these days ?

Steve

Afternoon All, looking at PCB software again, must say I am very disappointed in Autodesk and their attitude to things we have a few Autodesk products at work inventor, AutoCAD mechanical & electrical. We don't make many PCBs and looked at eagle 9.4 to find that they have gone subscription biased no...

Hi

Not got V8, but in V7 you can read the ADC using

"read as string" have you tried this ? then you can define the length of the string to 4
