[Emc-users] mesa 7i76 and 5i25
The 7i76 datasheet says 8-32v input. It would be handy for me to use my 40v supply. Is there some reason this won't handle more than 32v? Reasons for questioning.. A8499 = 50v http://www.allegromicro.com/~/media/Files/Datasheets/A8499-Datasheet.ashx Input cap = 63v Question 2 for the 5i25: How do I go about using mesaflash on linux? I tried running mesaflash from the command line but it just says command not found. Last go around the linux utility wasn't out, so I used the dos utility and it took all day to get it right, plus had to program the card in a different machine. -- Is your legacy SCM system holding you back?

Yes, the output drivers are rated 40V absolute max and the firmware will bellyache about it if VField 34V or so Reasons for questioning..

I tried running mesaflash from the command line but it just says command not found. If you got it from the zip file you need to chmod +x mesaflash to turn on the execute permission so then sudo ./mesaflash --device 5i25 --write someoldfpgafile.bit ought to work remember you need to power cycle the PC to load the new firmware Last go around the linux utility wasn't out, so I used the dos utility and it took all day to get it right, plus had to program the card in a different machine. -- Is your legacy SCM system holding you back?

You also probably need to use a full path and a leading dot-slash.

Re: [Emc-users] mesa 7i76 and 5i25
Thanks for this info. How might I go about beefing an input to handle a 40v input? I'd like to monitor the main supply somehow(with analog). I have a hot air gun, could change a resistor, or perhaps just add an external to adjust the divider? It looks like you use arrays. @Peter A side note, mesa board routing is very nice. What Cad program are you using? These aren't autorouted, are they? Silkscreen pinout def's would be nice on these boards though.

The input divider is a total of 22K Ohms and 36.3V full scale so a series resistor of sat 4.99K would get you to 44.55 V full scale @Peter A side note, mesa board routing is very nice.
