![]() After it says verified/pass then unplug the cable, wait 10 seconds, plug it back in, wait another 10 seconds, then open xwhatsit's newest version of the GUI (0.9.0?) and if it opens then you were successful. Here are the troubleshooting/firmware installation steps I suggested to wcass over PM (I assume they did not work for wcass): To install the firmware using Windows (I don't know about the other OS installation procedures), after assembly you would install atmel flip, plug in the USB on the controller and plug it into the computer, then go to device manager, right click the "Atmel" device, click have disk, go to the Atmel Flip installation folder, allow searching subfolders, and install the driver, then load atmel Flip 3.4.7, click the chip icon "select a target device" and pick atmega32U2, click OK, then click the USB icon, click USB, click Open, then click File, Load HEX file and select the firmware hex file, then click run. Details include: DipTrace Starter - 75 DipTrace Lite- 145 DipTrace Standard - 395 DipTrace Extended - 695 DipTrace Full - 995. Wcass in Windows device manager does it say ATMega device when you plug it in? DipTrace offers a free trial for 30 days after which it is available on perpetual licenses. The design I came up with is this …įYI all - I am hoping to use this redesigned controller with the F62/F77 keyboards. This allows me to route the row traces with a little more freedom. I made a few assumptions that I believe to be true the big one being that row order do not make any difference at all. Changing the crystal meant that I had to change the value of the load capacitors slightly. I changed RP1 and RP2 for a single bussed resistor pack (RP12) and went for a much smaller crystal to save space. Red chose to replace the ultra fine pitch surface mount component shift register that Xwhatsit used with a larger (but functionally equivalent) footprint and that seemed like a reasonable replacement to me. Like Xwhatsit and Red, resistors and capacitors are 0805 (except for resistor packs). Red had designed for 0.05” pitch ribbon cable I considered that to be too fine for normal folks (like me) to hand solder, so my design goals were 0.1” pitch ribbon (easy to source) all in-line, expansion header on left or right side, and convenient mount holes – all in a nice small package so as to easily fit in small places. Lucky for me, when I started this, Red had just published a DipTrace redesign version of Xwhatsit’s and I started with his schematic. I tried a bunch of EDA software and … let me just say that, IMHO DipTrace is vastly superior to KiCAD and is free for hobbyists (up to 300 pins). I have been a hobby draftsman for about 30 years and have a fairly good understanding of plumbing, so I thought I could rearrange Xwhatsit’s Model F controller to make it more convenient to use in new capacitive keyboards this despite having no electronics experience or training at all.
