Greetings all; Detective stuffs, electronically, have always been my specialty. But I have one now that is a bit of a puzzle even for me.
First, I mesaflash verified all 3 of my 7i90's. Then I hung them on the pi, and all of them returned the error I have posted quite a few times already. So I ordered that up-board. In the meantime I am less than ecstatic about that 1366x768 monitor, so I hit wallies and found a 1920x1080 AOC that the sales type said had an hdmi input. $88, so it followed me home. On unpacking I noted two things, first being that its power supply was a wall wart that plugged into the usual round socket on the bottom of the interface ridge on the back. 2nd was that DVI was the best input it had, requiring an hdmi to DVI adapter be inserted and screwed down, and the hdmi plugged into that. Mounted it where the other 1366x768 had been hanging, discovering the arm's bracket nicely covered the I/O shelf, making it quite difficult to get things plugged in and screwed down. Several hours later I finally got /boot/config.txt configured so it ran at its 1920x1080 rated resolution. Looked good. Tried linuxcnc, and darned if it didn't run normally once I had taken a pin reference to a units pin back out. No biggie, that card didn't have that module on it. So now I am wondering if the old, bastard 1366x768 rated monitor was somehow grabbing a gpio pin and mucking things up by interfering with the SPI buss. Am I on the right track, or barking at the moon? Discussion please. In the FWIW category, the 3 adapters I made, using the OSHPark 40 pin to 26 pin board with the 3 88 ohm terminator resistors, which because there were not any 88 ohm r's at digikey, so mine are 86.7 ohms. None of them work at all. They all return: 00000000 00000000 00000000 00000000 when queried for the boards id. My home made cable is the only one that works, about 8" of overall length. The very poor keyboard and mouse response continues unabated. This is regardless of the cpu load. Reboot it. 3 out of 4 times that will fix it for a while, 4th time its even worse. Misses key up events, so it goes into the autorepeat until another key is tapped. Hit backspace to get rid of the unwanted characters and the backspace goes into autorepeat. nano or geany makes no difference. Changing keyboards has no effect. I don't have the machine moving yet, when I decided to test ALL the 7i90's I had, I ripped stuff off the 50 pin sockets w/o drawing a map, so now I am tracing down each wire in turn, and plugging it back into the 7i90 by looking up that items function in my .hal files. That and because many weren't in a connector housing, and I want to rectify that, I tried to glue up 2 and a half of the 2x10 styles, but apparently the latest and greatest in super glues is not up to butt gluing these things, it breaks VERY easily. Made more difficult because there are not any Mesa 7i42TA's in the states and I want to get three of them to serve as static voltage absorber's to protect the ultra sensitive 7i90 outputs. Not to mention that it will make the hookup buckets neater. And wasted the afternoon getting the 1st of a 3 shot series under my left kneecap. And Dee, who watches the news, says we are supposed to get around 2.5" additional rain over the next 2 days. I wish humans could hibernate... Sometimes I try, but I still have recycle the water. :) Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
