Problem uploading sketch in verify phase

-

the following applies arduino -1.0 on linux(64 bit).

i ported ide run on atmega2561 in stk500/stk501 dev board. (modified pins_arduino.h , boards.txt) bootloader stk500v2 @ 115200 16mhz clock. set fuses using avr studio , jtagmkii (on windows machine).  used avrdude command line burn bootloader controller (from linux computer).  verified avrdude connect bootloader (avrdude -pm2561 -cstk500v2 -b115200 -p/dev/ttyusb1) this  on linux using usb serial dongle plugged stk501 db9.  .1uf capacitor soldered db9 pin 4 rst line on stk500.  boards.txt file modified entry stk500/m2561 having correct baud rate , bootloader entries.  able download sketches board using ide, don't verify.  downloaded simple blink example , modified go faster.  during download led stops blinking verifies ide reset board.  following output in verbose mode can see download proceeds, gets stuck during verify readback phase during see "timed out" message.  if exit ide , reset board manually newly loaded sketch runs.  can manually load sketch avrdude command line using verify option compile sketch , find hex file in /tmp/buildxxxxxx directory.  manually loading avrdude command line verify download correctly.  somehow ide not communicating correctly avrdude.


just make understand: when upload command-line, verify work?  or have avrdude skip verify?

Thread: PKI Client 5.00 install (for eToken Pro)

-
my company uses aladdin etoken pro authentication on vpn connections. etoken requires pki client application on client machine before os recognize it. app , token work fine on xp, use ubuntu on laptop. aladdin has offered linux version of client, rpm. convinced our internal guys rpms, , i've been trying work couple days. begin with, hp pavilion dv4-1435dx laptop running jaunty 64-bit. - started out converting .rpm .deb using alien: code: sudo alien -d pkiclient-5.00.28-0.x86_64.rpm - worked fine , got nice little .deb - next, ran .deb install client: code: sudo dpkg -i pkiclient_5.00.28-1_amd64.deb - , executed without errors/issues. pdf rpm said there should launcher @ applications > etoken > start etoken pki client, didn't exist. figured might because installed deb instead of rpm. bounced box, still wasn't there. no big deal... - install network manager can configure vpn connection use token: code: sudo aptit...

ATmega2560-Arduino Pin Mapping

-
hi community, in last days working on project using arduino mega 2560. on planning pin using found bugs in atmega2560-arduino pin mapping . if right there labels (such pwm) in 'mapped pin name' @ wrong row ( mixed pin numbers right one...) in attachment openoffice calc , pdf file corrected table. ( hope ;-) ) i post here tab separated table : code: [select] arduino mega 2560 pin mapping table atmega 2560 pin out arduino mega function nr name function function function mapped pin name function function datasheet 1 pg5 oc0b digital pin 04 pwm 2 pe0 rxd0 pcint8 digital pin 00 rx0 (usart0 receive pin, programming data input or pin change interrupt 8) 3 pe1 txd0 digital pin 01 tx0 (usart0 transmit pin or programming data output) 4 pe2 xck0 ain0 (usart0 external clock  input/output) 5 pe3 oc3a ain1 digital pin 05 pwm 6 pe4 ...

Crossfader Arduino Tutorial

-
hello i'm super newb please don't bash me much. i'm using led's , i've connected them correctly (finally) , wondering why program here ( http://www.arduino.cc/en/tutorial/colorcrossfader ) doesn't work? say's haven't declared crossfade. read directions on top , said crossfade needs used list order of colors. isn't declared in main part (void loop() )? or need declared before? nevermind void on bottom , needed before voidloop. lol anyways playing rgb led's wondering if has specific way of making them fade in , out different colors? (brightness , color mixing) code: [select] /* * code cross-fading 3 leds, red, green , blue (rgb) * create fades, need 2 things: *  1. describe colors want displayed *  2. list order want them fade in * * describing color: * color array of 3 percentages, 0-100, *  controlling red, green , blue leds * * red red led @ full, blue , green off *   int red = { 100, 0, 0 } * dim white 3 l...
