Reverse engineering a 12 pin 4 digit display

-

hi everyone! i'm developing project university allows me control eletrical moka remotely.
for case study took alicia de longhi (http://www.lucaelettronica.it/catalogo/images/emke21.jpg) has 5 buttons , display.
the display has no name or code or allows me understand model , find out datasheet or @ least how pins have driven.
it's 4 digit display 12 pins in row (not 6 on side , 6 on opposite side).
to more specific there colon between first 2 digits , other 2 digits, in way -> 12:11. there no decimal points.

can me understand how pins driven? found nothing on internet!

thank in advance,

diego

that consumer product. unlikely able it. these aggressively designed down price point , such take short cuts byproduct render difficult re use.

your first step @ signals oscilloscope , see if logic signals or if direct lcd signals, in case multi level.

¿conocéis este proyecto? fvdw-sl 15.3 para raspberry pi. convierte la raspi en un nas. http://plugout.net/viewtopic.php?f=31&t=1880 llevo tiempo intentando encontrar la forma de hacer que una de mis raspberry se comporte como un nas. configurando samba, minidlna, transmision, ftp, nfs, etc. pues con esta distribución lo tengo todo hecho. lo instalé ayer y me tiene soprendido. ahora mi raspi es un nas, hecho y derecho. caracterísitcas. - interfaz web. que cambia en función de si eres el administrador o un usuario. - gestión de usuarios. puediendo dar distintos permisos carpetas y funciones. - gestión de carpetas - vpn - ftp - nfs - webdav - varios servidores dlna como minidlna, townky, etc - varios gestores de descarga como transmision, mldonkey, etc - gestión de periféricos usb como impresoras o webcam. - gestión de cron para automatizar procesos. - creo que se basa en arch linux. por cierto, estoy creando una tarea para que me exporte un archivo txt del dis...

i have external server running mysql. have installed php script that, when accessed http deliver data 1 of tables. works fine browser: code: [select] http://www.seti.net/php/getevents.php i cannot figure out how send command arduino. have ethernetclient library working , can access google in example. when send command through client: code: [select] client.println("//get /php/getevents.php http/1.0"); the server returns: code: [select] </head><body> <h1>method not implemented</h1> <p>get /php/getevents.php not supported.<br /> what correct way format in arduino? i use send temperature web server. note lack of http version , additional blank line after - not sure whether difference important works: code: [select] void  sendtemptoserver() { char getrequest[80]; if (client.connect(server, 80))   {   sprintf(getrequest,"get /cgi-bin/arduino.cgi?reading=%s&arduino_id=23&sensor_id=1",t...

hello, im confused uno r3, uploaded code quite few months in uno, working fine. now without having altered of circuits, trying upload code changes,im getting strange error "avrdude: verification error, first mismatch @ byte 0x0000          0x0c != 0x62" i tried research able solve issue,  im running kind of fuse bit being changed or clock speed altered, im pretty sure did not play around these items. any people, please . . thanks taz Arduino Forum > Using Arduino > Installation & Troubleshooting > avrdude: verification error, first mismatch at byte 0x0000 0x0c != 0x62 arduino
