Compiling firmware for Atheros based wifi. [Tutorial] - Raspberry Pi Forums

-

debian wheezy , jessie repos including old version firmware. i'm compiled new firmware. running realy better.i'm compiled firmware on rpi2 & raspbian

firmware compilation tutorial qualcomm atheros ar7010 , ar9271 usb
802.11n nics
( sample products: tplink tl-wn722n, netgear wna1100 )

sudo apt-get install lshw
sudo lshw -c network

#this command result showing firmware version. before compiling firmware mine 1.3.0

#install required packages:
sudo apt-get install build-essential cmake git m4 texinfo && exit

#clone repo:
git clone https://github.com/qca/open-ath9k-htc-firmware.git
cd open-ath9k-htc-firmware

#"checkout latest tagged release" disabled. "master branch" working.

#build toolchain:
make -j4 toolchain
#(-j4 option rpi2)
#(this long process. 1-2 hour pi2.)
#(this proccess download support files net.if wifi disconnected when doing process download. pls reconnect net connection or fix it. run make -j4 toolchain again.

#build firmware:
make -j4 firmware
#(-j4 option rpi2)

#install firmware:
sudo cp target_firmware/*.fw /lib/firmware/ && exit

#reboot system

#testing new firmware version
sudo lshw -c network

#tutorial source: https://wiki.debian.org/ath9k_htc/open_firmware

i'm used set wifi region code. running better.
driver default selecting "cn" (china) code

#regulatory domain list countries
http://www.arubanetworks.com/techdocs/i ... 51_1017918
#command (for england):

iw reg set gb

#command showing wifi region info (mine showing first cn, after changed i'm selected.)

sudo dmesg |grep 80211

dear all, working on image processing using raspberry pi, have installed intex usb web camera on raspberry pi. have used basic python script of image processing https://www.cl.cam.ac.uk/projects/raspb ... first.html required libraries installed on raspberry pi. script code: import imgproc imgproc import * # open webcam take pictures camera = camera(160, 120) # open viewer window display images viewer = viewer(160, 120, "the first step") # take picture camera img = camera.grabimage() # display image in viewer viewer.displayimage(img) # iterate on each pixel in image x in range(0, img.width): for y in range(0, img.height): # value @ xth column , yth row, place intensities variables red, green, blue = img[x, y] # test find colour dominant if red > green , red > blue: # red dominant, set pixel red img[x, y] = 255, 0, 0 elif green > red , green > blue: img[x, y] = 0, 255, 0 else: # if red or gr...

i have laptop dead motherboard . can remove components laptop , in anyway possible connect raspberry pi inbuilt display , keyboard on laptop ? (and touchpad if possible). (i figured remove components inside , fix pie inside , use extended usb cable , connect available usb ports respective holes in laptop skeleton, same headphone out ) . i'm noob when comes pi . on topic appreciated if screen lvds type may possible use screen installing converter board. this: http://www.ebay.com/itm/hdmi-dvi-vga-dr ... 3027&rt=nc need model number of screen , ask seller if work. or search ebay using brand , model number. assuming screen in working order..... back-light not burnt out etc.. other devices...... can used if have usb interface not part of motherboard. have make connector. raspberrypi

Smoothing Capacitor value?

hi everyone! i have question "smoothing capacitors". have 5v arduino project have 6 individual 5v components attached it. since need these running @ different times, wanted take similar approach of nick gammon's in helpful example (http://www.gammon.com.au/forum/?id=12106) , use few mosfets switch these little guys on & off individually (instead of regular arduino pins), while minimizing potential power surges affect microcontroller and/or components themselves. these components 5v, , have maximum draw of ~170ma when powered on @ same time. so, if used 6 different mosfet switches turn switch +5v power line on each component directed via arduino uno, wondering: 1. still use 1 capacitor (like nick did in example)? 2. capacitor of 100uf work, or should use bigger? my plan first test circuit mosfets & capacitor(s) using usb, , later on, moving project battery power. thanks in advance ideas & suggestions! quote these little guys what ...
