hi, 1st post. i have been working through arduio code , have hope basic question. in code below works 'duration' multiplied 1000l. why l @ end? what mean. code: [select] void playtone(int tone, int duration) {  for (long = 0; < duration *1000l; += tone *2) {    digitalwrite(speakerpin, high);    delaymicroseconds(tone);    digitalwrite(speakerpin, low);    delaymicroseconds(tone);  } } i'm tryingt o understand when multiply 1000 , when multiply 1000l. i tried removing l code failed, important. any info appreciated. albert. quote why l @ end? mean. the l declares value long. without l, value of duration * 1000 interpreted int, can hold maximum value of 32,767, limiting duration maximum of 32. with l, duration * 1000l treated long, can hold larger value.

hi, i started experimenting today interfacing arduino computers com-port using max232 chip. my code comes out of tutorial: arduinosoftwarers232 (i'm not able include hyperlink first message on forum -the tutorial can found on website) hardware set in tutorial, chip different , i'm using pin 7 , 10 tx/rx i open hyperterminal , set 9600 baud, 8 databits, no parity, 1 stop bit, described in tutorial. when start typing in character, return me character, not right one. by comparing binary values in ascii table able tell decimal difference between typed , returned character 128. figured somehow there problem 8th bit. when set hyperterminal settings to: "9600, 7databits, no parity, 1 stop bit" problem seems solved. when type in "a", character "a" returns. also, debugging start message "hi", appears "45" , non-displayable character. basically, problems have: -why "hi" doesn't display? -why have set hyperterminal ...

i using arduino control stepper , i'm having difficulties reaching speeds required. tried sort of doing manual pwm create step pulses: digitalwrite(steppin, high); delay(dly); digitalwrite(steppin,low); delay(dly); but can't seem attain frequency high enough (my steady state speed needs 1000 steps/s). through searching found possible change frequency of pwm arduino puts out. should able use create pules, however, haven't seen vary frequency within void loop love able create type of acceleration profile. know may not possible figured i'd ask see if has ideas. quote (my steady state speed needs 1000 steps/s so value in delay need 0.5ms, shortest can delay 1ms fastest speed can 500hz. it's slower in reality because write takes time well. quote i tried sort of doing manual pwm create step pulses: if feed pwm signals stepping motor not control it's speed. look @ arduino code in reprap project how accelerate stepping motor arduino. ...

this first post, hi all! got pi in mail, , , running first time. plan on using on road on couple different wifi networks, , not want carry monitor in backpack. have coming in mail: http://www.ebay.com/itm/330646461862?ss ... 1497.l2649 (i read in thread few people successful product) solution this: wright script that, upon start-up: automatically connects ethernet network if available automatically connects known wifi network if available if ip address exists, wright ip address , network name serial port (a peripheral display it) way, when start device, connect, , have ip address ssh , whatever else need. i'm interested in using remote desktop. however, i'm rather new linux, , new networking. i'm not quite sure how make work, or if best solution "get on arbitrary network without display" problem. want point me in right direction? guys! welcome! aside lcd, popular linux distro rpi, raspbian, works out of box, no script required. have conf...
