hi, i have been unable print ds18b20 temerature sensor st7735 tft screen adafruit. 128 x 160. prints fine serial monitor. i had expected following section calling temperature in celsius able print? appreciated. code: [select] {  sensors.requesttemperatures(); // send command temperatures.  mytemp0 = (sensors.gettempcbyindex(0));  mytemp1 = (sensors.gettempcbyindex(1)); { the following far have been able get. code: [select] #include <spi.h> #include <tft.h> // libraries ds1820 , onewire #include <onewire.h> #include <dallastemperature.h> //you can use (4 or) 5 pins   //#define sclk 4 //#define mosi 5 #define cs 6 // pin definition uno #define dc 7 // pin definition uno #define rst 8  // pin definition uno // can connect arduino reset float mytemp0; float myhightemp0; float mylowtemp0 = 50; float mytemp1; float myhightemp1; float mylowtemp1 = 50; onewire onewire(2); // setup onewire instance communicate devices. dallastemperat...

i want display values in graphic way without seeing bunch of numbers running through screen. want see statistics people can understand happening. there program can useful? i have used processing write programs display data sent uno pc via serial port.  processing free open source programming language quite similar the language (c++) used program arduino (the arduino ide based on processing ide).

hi, i've server openldap setted up, , has been working last 2 month without problem. 2 days ago started segfault randomly, every 60 90 min aprox. taking @ logs cannot see gives me hint happening. i've had set cron job start slapd every 30 min, keep working. don't think it's related hardware failure, since it's inside vm server , other servers didn't had trouble. error is: sep 29 18:03:49 earth kernel: [ 3460.052677] slapd[2522]: segfault @ 0 ip 00007f20f0285ee6 sp 00007f20eab933d8 error 4 in libc-2.9.so[7f20f0205000+168000] package information: package: slapd status: install ok installed priority: optional section: net installed-size: 4176 maintainer: ubuntu core developers <ubuntu-devel-discuss@lists.ubuntu.com> architecture: amd64 source: openldap version: 2.4.15-1ubuntu3 replaces: apparmor-profiles (<< 2.1+1075-0ubuntu4), ldap-utils (<< 2.2.23-3), libldap2 provides: ldap-server,...

i have mkv file has somehow gotten warped, because movie resolution 10 x 800 (i hope have right). in other words, movie 1 cm wide, height high screen. know how fix this? don't know if can extract original movie file (with audio, of course) mkv file, or if knows of ubuntu tool can fix this. i'd appreciate it! the chances of file being corrupted very, low. it's more media player set play @ ridiculous aspect ratio. (from time time, manage hit right hotkeys this.) if media player has option change aspect ratio, try different things until find right one. if file, open mkvmerge-gui (known mkv file creator in menu , in mkvtoolnix-gui package) , force correct aspect ratio in "format specific options" tab.

so, purchased atmega 328 online. still waiting in mail,. , wondering difference between 1 in photo (the 1 ordered) , arduino boards such uno, can use atmega 328 board.  have same capabilities? limits compared uno/other boards?? quote from: lindhoutd on mar 31, 2014, 10:29 pm so, purchased atmega 328 online. still waiting in mail,. , wondering difference between 1 in photo (the 1 ordered) , arduino boards such uno, can use atmega 328 board.  have same capabilities? limits compared uno/other boards?? it has a7 , a8 (see photo). it doesn't have 3.3v output pin.

hi, used via ciii board xubuntu network onboard (eth0) , usb nw-adapter (eth1). changed intels atom board, of course onboard nw. ifconfig calls eth3 (or pan0, seems me, pan0 else, don't know what). network manager doesn't find sufficent way work card, not fixed-ip nw , not (a)dsl. pppoe-config doesn't see adsl nac, testing eth3 , pan0 too. i'm on suse, don't know how configure network on xubuntu, first delete somewhere hidden old entries seem disturb thing... thx idea cu jth you need go /etc/udev/rules.d/70-persistent-net.rules delete devices & reboot can detected new.
