Hello,I've already visit a very intersting website :www.opencopckpits.com . They build industrialy cheap IO board like fsbus, but about 70 Euros you have the master Card+ the display Card to command 16 7 Segment display. They ship worldwide.I've just order two kit (pcb+components), and i'm waiting.Stay tune for comment, and if you have heard something about , tell me more..Xavier A320 home build from France

Hi>:www.opencopckpits.com . They build industrialy cheap IO board>like fsbus, but about 70 Euros you have the master Card+ the>display Card to command 16 7 Segment display. They shipYou can drive 16 7 segment displays with a cheap microcontroller and one extra chip. Cost: about 5EUR. Add a MAX232 for a few cents and you can hook it up to the serial port. Or, instead, use a FT232 for less than 10EUR and you've got USB.Firmware/microcontroller sourcecode available here: http://cockpit.varxec.de/software/pic.htmlManuel

How's your Master Card and IO Board coming along? Anyone else use this?

Their web site is now this: http://www.opencockpits.com/index.php

Salut Xavier,I prefer to wait a bit for the Electronflux by Leo Lacava.www.betainnovations.com.It will be high speed USB - Opencockpit and FSBUs are still Serial. I do read everywhere that most user have delays in response when too much linked card are used.Roger

Hi Manuel,Many thanks for the microcontroller code for the 7-segment displays.I could not find a schematic on your site. Is it there?Best regards,Kev

Hi Kev,> Many thanks for the microcontroller code for the 7-segment displays.> > I could not find a schematic on your site. Is it there? No there is no schematic... but i've drawn one up quickly:http://forums.avsim.net/user_files/53955.jpgIts pretty simple, the 4067 (16x analog switch) switches the addressed X0..15 side to the other side X thats grounded. The PIC simply scans the 4 bit addresses to the 4067 while turning on/off the bits of the port the 7 segment displaysare connected to (via resistors, something around 220, 330).My setup is for common cathode displays, but its easy to change into common anode: Just connect the X to 5V instead of ground and then add ONE line of code to invert the bits for the 7segments. To really use the circuit and code, you'd probably wanna change something, because the asm file contains codeto talk to another PIC via my PIC-to-PIC protocol (very simple one wire protocol).I have all necessary asm code to make this circuit usable via RS-232. You'd have to hook the 7segs to PortA instead of PortB,and move the 4067 address lines to PortB<4:7>. This leaves the RX/TX lines free to hook up a MAX232 :-) The original circuit was built on a breadboard (as seen on some pictures in the galleries). I took all my prev designs, including this one, to create a "one-size-fits-all" PIC home cockpit controller (PHCC), that I'm working on currently.
