hello everyone, i started programming arduino , and i'm making project read rpm , speed of car using arduino uno. far got working speed value not show properly. have used 1 hardware counter , 2 interrupts in project. 1. timer 1 on pin 5 - count pulses car's ecu calculate speed. 2. int0 on pin 2 - read ignition pulse calculate rpm. 3. int1 on pin 3 - 5v in headlight switch control brightness of display (max729 7 seg 8 digit). i can proper reading rpm , brightness control working properly. here codes below. code: [select] #include <ledcontrol.h> // inputs: din pin, clk pin, load pin. number of chips ledcontrol display = ledcontrol(12, 10, 11, 1); //speedo----------------------------------------------------------- const int hardwarecounterpin = 5; const int sampleperiod = 1000; //in milliseconds const float pulsespermile = 4000; // pulses per mile toyota. other cars different. const float convertmph = pulsespermile/3600; unsigned int count; float mph; int kph; int...

estou com um problemao. eu mando instalar um componente, ele fica um tempao pra atualizar tela e, em vez da tela de "instalacao concluida" eu recebo mensagem: another component using directory: ".../www/components/.../" o estranho é que são componentes novos, que nunca haviam sido instalados (à excecao joomlaxplorer, que tb esta com esse problema). as pastas sao criadas (via ftp eu consigo ve-las), mas eles nao aparecem no painel de controle joomla. por que isso acontece? os componentes sao : joomlaxplorer docman joomlaboard não tem nenhum problema de permissão nos teus arquivos? ou na estrutura de diretórios das pastas ou no arquivo xml que acompanha? já passei por algo parecido, só que com template. creio que era porque estava fazendo upload da pasta errada, mas mesmo assim o joomla diizia que o componente havia sido instalado com sucesso.

i run 80 joomla sites. what want have central page / site whos on details of sites in 1 menu / list. has done ? thanks peter no, should possible. you have create database connections (with query retrieves info jos_users & jos_sessions list) 80 different sites. however, sites's databases must accept external (from other servers) connections. connecting other servers/databases takes more time retrieving information default database (like regular joomla site does). another possibility might be: using rss. sites should have rss link lists active users, , sort of newsfeed component @ central page, info retrieved , displayed on 1 page. forsee similar performance issue though...

es wird ja öfter mal darüber diskutiert, dass bugs in den verschiedenen libraries sind, die nicht gefixt werden oder dass man gerne noch das ein oder andere feature mehr hätte. deshalb wollte ich mal hören ob bei euch ggf. interesse einem community-fork sowohl für die libs als auch für die ide besteht, den wir gemeinsam weiterentwickeln könnten. natürlich müsste ein projekt international aufgestellt sein ... aber wir können ja hier im deutschen teil schon mal über sinn oder unsinn diskutieren. ich würde mich deshalb sehr über eure meinung zu einem community-lib/ide-projekt freuen. problem wird sein, immer und überall entsprechende rechte anzufordern, die weiter zu verbreiten. wenn eine lib seit mehreren jahren nicht aktualisiert wurde, dann vermutlich aus dem grund, dass der programmierer keinerlei interesse mehr hat, ggf. bugs auszumärzen. das problem, ich hier sehe, ist die geringe anzahl leuten, die sich mit dem sauberen erstellen von libarys auskennen...
