Using the 2nd I2C bus on the 2B v1.1 - Raspberry Pi Forums

*note*: applies pi 2b rev 1.1 since took me time figure out, , it's dead simple, i'd thought i'd post here it, save else hassle. first of; usage of 2nd i2c port adviced against, @ least 2 reasons: 1) can used eeproms (id_sd, id_sc) during boot 2) it's used camera module if don't use eeproms or camera, might fine. use @ own risk. me worked. open /boot/config.txt , add: code: select all dtparam=i2c_vc=on after this, 2nd i2c port available on pins 27 (sda) , 28 (scl) (fysical pins) or id_sd, idsc. measure, , because it's technically correct, 1 should add external pullup resistors. cheers! you need add pull-up resistors 3v3 on pins 27/28 them work i2c bus. raspberrypi

Adding an ENC28J60 Ethernet module - instructions - Raspberry Pi Forums

hi folks, i've written instructions adding enc28j60 ethernet interface pi. project at: http://www.instructables.com/id/super-c ... pberry-pi/ simple enough school project, or kids. know it's 10mbit ethernet interface, it's surprisingly performance (i'm getting 350-400kbytes/sec downloading sd card images raspberrypi.org ) , it's really cheap. comments welcome, ian hi iam have followed instruction use enc28j60 raspberry have problems when accessing module. idea have original interface (eth0) connected internet , use enc28j60 additional interface (eth1) attach ip camera , stream use of rtsp. ip eth0 need assigned dhcp , eth1 fixed (need fixed rtsp url). have attached pins describen , when running command code: select all ls /boot/overlays/enc28* abble se right message. if run command ifconfig can see additional interface eth1. despite all, there 1 interesting message " interrupt:249 " @ end of interface eth1. problem? code: select all eth0

Aide pour robot ultrasons

bonjour, je suis en 1ère s et je dois présenter un tpe cette année. notre sujet est : "comment le robot t-zÉ fait-il pour sortir d'un labyrinthe?" (t-zÉ comme thésée de la mythologie ) pour ce faire je dois programmer un robot sur arduino. j'ai donc acheté un shieldbot , des capteurs ultrasons (j'ai les v2.0) et une carte arduino uno . le code en français: le est de garder toujours un mur à sa gauche pour sortir du labyrinthe. (il y 2 capteurs ultrasons, un à gauche et  un à l'avant) gauche=g droite=d mur=1 rien=0 g=1 a=0 alors avance g=0 a=1 alors tourne gauche g=0 a=0 alors tourne gauche g=1 a=1 alors tourne droite malheureusement, je débute dans la programmation et c'est un peu dur pour moi, je n'arrive pas à faire marcher les capteurs, de plus je ne sais pas sur quel port grove brancher les capteurs... avez-vous avez des conseils ou des idées parce-que je n'ai pas trouvé de tutoriel intéressant sur internet (pas faute d'avoir c

PPM 16 voies

Image
bonjour, je voudrais réaliser un codeur ppm et envoyer ce signal via un tx openlrsng https://github.com/openlrsng/openlrsng/wiki/hardware-guide sur la doc de cet émetteur je lis qu'il faut lui envoyer une trame ppm et qu'il gère jusque 16 voies. de ce que j'en sais, la trame ppm à une longueur de 22,5ms et chaque pulse 2ms au max. comment on passe 16 voies dans 22,5ms ? y a-t-il plusieurs types de ppm ? ou une astuce que j'ignore ? quelqu'un peut-il m'éclairer sur le sujet. yep! généralement, on ne peut envoyer que sur 8 voies. après, je ne vois aucune obligation de respecter en ce qui concerne le ppm ni le timing de 22,5 ms ni les standards imposés (en-tête, espace, etc). les constructeurs rc ne le font pas. l'essentiel étant de faire un truc qui marche. @+ zoroastre.

Schlüsselschalter gesucht

hallo zusammen, ich hab ja in meinen terminals schalter drin, zum ein- und ausschalten. aber die bekommen ja auch andere leute in die hand und da kanns ja dann - absichtlich oder unabsichtlich sei mal dahin gestellt - passieren, dass das ding wer ausschalten. aus dem grund hab ich mir gedacht, ich bau schlüsselschalter ein. alle schlösser mit dem gleichen schloss und schon ist das problem erledigt. jetzt ist aber das problem dabei, den richtigen schlüsselschalter zu finden. einen 3-poligen "wechselschalter mit mittelstellung aus" hätte ich bereits gefunden (fragt aber besser nicht, mit welchen bedingungen..). dieser würde passen, wenn ich 1 akku hätte (1. stellung akku laden, 2. stellung aus, 3. stellung gerät an). allerdings brauch ich, wenn ich die funkmodule einbau, zwei akkus. für "gerät ein" würde der vorhin genannte schalter ja reichen: einfach beide akku's auf den pin löten. aber zum laden ja nicht, von wegen balancer und so. da würde ich einen

Database Publishing

hallo, ich möchte einen katalog erstellen, dessen daten aus der datenbank kommen. es gibt verschiedene produkte mit unterschiedlichen layouts. ausserdem werden tabellen zur darstellung von varianten benötigt. zur realisierung benutze ich vb mit indesign scripting. jetzt meine fragen: 1. bringt mir xml etwas? 2. wie kopiere ich ein template? 3. wie kann ich tabellen ggf. mit vorlagen aufbauen? da ich indesign anfänger bin, suche ich noch den rechten weg zum ziel. gibt es beispiele? vielen dank im voraus! harald hallo harald, natürlich kann man mit indesign einen database publishing prozess erfolgreich umsetzen. es gibt jedoch recht viele verschiedene möglichkeiten, dies zu tun; es kommt immer darauf an, - welche art von katalog produziert werden soll - das layout eher statisch ist (seitenorientiert) - oder eher dynamisch (orientiert produktdaten) - in elcher form die produkte gruppiert und sortiert werden sollen - bilder zu den produkten und vieles andere mehr. die

Interfacing Arduino Micro with another digital device

i have arduino micro, , rn-52 bluetooth audio module want control arduino. the rn-52 3.3v device, , can controlled on uart interface when pin gpio9 pulled low. it has 'event' signal on gpio2. gpio2 floats high (3.3v) , goes low 100 ms when event happens. @ point i'm supposed enter terminal mode pulling gpio9 low, waiting 'cmd', entering 'q\r', , parsing result. think know how can micro. with background, best way of working gpio2? should connect digital pin , use isr? or polling of main loop fast enough doing digital read work? also, since rn-52 3.3v , micro 5v, can use digital inputs @ all, or should reading analog line? think digital state change means 3.0v -> 0, want sure. thanks in advance or advice. if you've got 100ms on signal think catch normal polling in loop.  that's pretty long time in microcontroller terms unless have bunch of other code blocking.  the 3.3v thing tough.  i've used 3.3v spi devices sd c
