ubuntu - Cannot program Atmega1284p with arduino on linux, works on mac -


this issue driving me nuts. working on project other guys built electronics. have custom boards atmega 1284p. usb cummunication 1284p use ftdi ft230x usb bridge. doesn't have dtr; rts used reset board using capacitor (pretty off shelf arduinos).

the arduino bootloader used, , use mighty-1284p upload. board selected "original mighty 1284p 8mhz". after installing right ftdi drivers http://www.ftdichip.com/drivers/vcp.htm can upload board mac. linux has these drivers built kernel. however, cannot upload board. avr gives following error:

avrdude: ser_recv(): programmer not responding avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 5 of 10: not in sync: resp=0x00 avrdude: send: 0 [30]   [20]

dmesg gives following:

... [   51.299964] usbcore: registered new interface driver ftdi_sio [   51.300088] ftdi_sio 1-1.2:1.0: ftdi usb serial device converter detected ...

and lspci:

... bus 001 device 006: id 0403:6015 future technology devices international, ltd bridge(i2c/spi/uart/fifo) ...

the settings mac , linux machine identical. on both use arduino 1.0.5. both see correct serial port.

i've seen many posts in forum similar problems, have yet find 1 solution works me. holding reset, or clicking before uploading not work. suggested in forums have tried removing brltty no avail. have tried uploading arduino ide, eclipse avr plugin , avr via command-line. none work. i've tried on different machines different versions of ubuntu, , uploading works in none of them. adding -c arduino avrdude command doesn't trick either. ideas on how fix this?

my user part of dialout group, , can upload other arduino boards (like duemilanove) without problems.

this question asked here: http://forum.arduino.cc/index.php?topic=244363

you mentioned ubuntu; doing normal user?

if so, may need add account correct group, serial port device belongs to.

you can this:

sudo usermod -a -g dialout

then (easiest) logout , log in again.

however, possible called other dialout in latest ubuntu, haven't checked. can confirm still dialout here on debian wheezy.

(this little odd, though, if works; permission error instead...)

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
