Done that so many times, even the old arduino 1.8.18 complaint the same
ar488 master with the src folder "AR488 GPIB controller, ver. 0.51.15, 12/10/2022"
Even the old versions in the archive are not uploading ... sent an email to sparkfun
Even trashed the bootloader
It's an 32u4 based board at 16 mhz, tried a leonardo variant board type ... now it give me this :
Picture attached ---> Prologix gpib configurator see AR488 GPIB controller ver 0.51.15 ... ok but nothing else is shown or active for the other choices ??
QUESTION: how should an ar488 device be declared in the device manager ?? mine only shows as a serial device ... ?? baud rate speed ? 115200 or faster ?
some rant
Oh man i'm getting too old for this stuff, i'm forced to build an gpib adapter to try a majority of softwares who talks to gpib adapters / some does lan but i see there is no interest to make the 34410 34411 l4411 generations work or being added
WHY because the Keysight software only start the meter when doing data logging ....... i want to set things up before ...
I'm testing huge power cells and this meter was fine for this setup and would be easier to protect it against an exploding battery (vibration tests etc ..)
Talked to the Testcontroller creator to add some of them in his definition file but man even reading his documents is hard as h... i'm native french
Bought an L4411 meter thinking it would be easy to interface without this adapter, an simple to use software interface, to make the meter work BEFORE doing any data logging ... lost so many hours just to make an s#$$% (discovered too late) arduino clone from sparkfun work, even my never used mega 2560 doesn't want to be an ar488 ??
The sparkfun variant has to be resetted twice to get into DFU mode, you have 8 seconds to reflash it or do something with it
avrdude cant flash it fast enough and it will crash the 32u4 boot loader, (sparkfun made an updated bootloader) even my 1k$$ programmer would not recover it, because of the clock fuses it can not understand
way to go ELNEC
An old stk500 clone worked fine in isp ....
I'm happy to receive help from here ... thks even now i'm not sure how to configure it loll even reading the ar488 manual ...
