mesa 5i20 + 7i44 +7i73

ok, so I have to download and copy this driver for the folder where pncconfig gets the drivers? where can I find this driver?

tanks,
João

Yes, thats basically right, though its not a driver but rather FPGA firmware
that gets installed in the /lib/firmware/hm2/5i20/ directory.
in addition to installing the firmware there you will need to change the
config line in your .ini file that selects the firmware.

I don't think there's a current SVSS4_8.BIT around for the 5I20 so
I probably have to compile a current version sometime today.

ok I will appreciate it!

freeby.mesanet.com/SVSS4_8.BIT

tanks! it will be tested ASAP.

I am working on the same project that João (jtc).

We now have a bilking green light so I think that the firmware is fine.

As this is a research project in the company were we are both working, I stay concerned regarding the fact that this .BIT file was made after a request. This is, if PCW was unable to make it (for any reason), how could we possible manage to go forward with the hardware that we got? It would be something that others could make, or it is internal to mesa?

Thank you.

The source code for building the HostMot2 firmware is available from Mesa under a GPL license. This can be downloaded from Mesa's website (the source code is in the support software zipfile). For example here is the 5I20 zip file:

www.mesanet.com/software/parallel/5i20.zip

You can use the hostmot2 source to build any of the available firmware modules
(and add new ones). To do this you need the (free) Xilinx webpack software

Also I just noticed that there was a svss4_8.bit file in the zip file from Mesa. But the one I
sent is better as it incorporates the latest bug fixes in the sserial firmware

Tanks to all.

today we tested the 7i73 board and some buttons that have been wired are working fine.

Hi.

have to connect 2 outputs to 2 backligths (24v). I fount this on the 7i73 manual, but don't fully understand it:

OUTPUT CHARACTERISTICS
The output bits driven by the 7I73 are 3.3V LVTTL compatible with 4 mA drive
capability. It addition LVTTL output bits 0 and 1 have high current sinking drivers available
(OD0 and OD1). These two outputs can sink up to 1A at 24V. If used for driving inductive
loads, the load must include a free-wheeling (flyback) diode. If the high current outputs are
used, the LVTTL outputs 0 and 1 should not be connected. Outputs 0 and 1 have indicator
LEDs on the 7I73 card (CR3 and CR4 respectively).

so I can power the leds with 24v and use OD0 and OD1 has a Ground reference (and not use OUT0 and OUT1 )? and the power source ground, connect it to an p2 GND?
