problem with TP-link 725N (8188eu) - Raspberry Pi Forums

-

hi,
have raspberry pi, running "linux rpi3 3.6.11+ #474 preempt..."
have added tp-link 725n (v 2) dongle lately. after struggling bit 8188eu module, managed make connect lan...

challenge appears when want create ad-hoc network... have seen several posts on forum, claiming success building ad-hoc network... got strange behaviour on board...

1. iwconfig shows adapter seems initiated correctly:
"...rpi3 ~ $ iwconfig
wlan0 ieee 802.11bg essid:"mlpt2" nickname:"<wifi@realtek>"
mode:ad-hoc frequency:2.412 ghz cell: 02:11:87:bc:e1:01
bit rate:54 mb/s sensitivity:0/0
retry:off rts thr:off fragment thr:off
power management:off
link quality:0 signal level:0 noise level:0
rx invalid nwid:0 rx invalid crypt:0 rx invalid frag:0
tx excessive retries:0 invalid misc:0 missed beacon:0
"
@ same time, 'iwlist wlan0 scan' of times not shows mlpt2 network... ( occasionally, does. also, there 2 raspberries pi running near by... on both 'iwlist wlan0 scan' shows networks available around... no mlpt2...

2. blue led not working on unit... have seen forum threads, claiming fixed...

wonder if verified ad-hoc mode 8188eu tp-link adapters? there detailed instructions how fix?
there patches/development release/... etc. working correctly?

in advance help.

michael.

the led not work because in source files driver led disabled default. have compiled modified version enables led. can version of driver led working , install using following commands

code: select all

wget https://dl.dropboxusercontent.com/u/80256631/8188eu-20130209.tar.gz tar -zxvf 8188eu-20130209.tar.gz sudo install -p -m 644 8188eu.ko /lib/modules/3.6.11+/kernel/drivers/net/wireless sudo insmod /lib/modules/3.6.11+/kernel/drivers/net/wireless/8188eu.ko sudo depmod -a
may need remove driver using if not installed in same directory.

accessing forum , typing post using pi configured ap using tp-link tl-wn725n v2.

have used above driver , instructions here http://www.daveconroy.com/turn-your-ras ... s-chipset/. although states edimax ew-7811un should work rtl8188cus based device , works rtl8188eu devices far know. i'm using without problems typing post without difficulties.

couple of points instructions setting access point. instructions setting /etc/network/interfaces file in bridge network connections section little confusing. easiest copy final result shown. in section configuring hostapd don't forget use own network-name ssid= , network password wpa_passphrase=. in section wrapping up before try test sudo hostapd -dd /etc/hostapd/hostapd.conf should reboot first before trying test otherwise may not work.

hope helps

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...
