Hi; I use the Arduino as a proto tool, then build a pcb with an AVR and avr-gcc. I have a Mega2560 a Sarduino-644p, and a Sarduino 1284p Now that the Beaglebone Black has come out I will not be buying a Rasberry Pi.
I just wish that Fritzing thing would die quickly.
As a side note I bought my first calculator in 1974, VFD display it had square and square root, $50. It was not quite top of the line, (at that store).
Are you sure that you have identified pin 1 correctly? Page 13 shows the connector. With the display facing up, and the connector on the left. Pin 1 is lower inside.
If you have it backwards then you connect the backlight LED directly across the power lines. With no resistor the fuse will blow.
The black boxes mean that the contrast pot needs to be adjusted. Usually very near to one end of it's travel.
Hi Mats; very cool tool. I like the different footprints. On the sot-23 could you put a fake component behind it as a backrest?
If you sell them sign me up for one.
btw I just checked your site: "July 17,2013 - The SmallRoomLabs site has been hacked. Currently restoring from backup and patching holes. Please come back later."
Hi Stefan; I did a search for"bi-directional fet voltage translator", and "i2c opto-isolator". I got quite a few results. The ISO1540 at Mouser is $4.95.
The buffer just drives the LED's - so not critical.
I am always nervous plugging my little BP into a new circuit. So I am very interested in your progress on this.
This is just a hobby for me now, so I am not up on the the latest parts.
You can hand solder a 1mm part with 4 wires on a side ?. I live on coffee, so no.
