PAM8403

這個CHIP真的很厲害,小小一片,加組4歐姆3瓦的喇叭及USB電源即可達成一組電腦音箱,便宜又好用.難怪無線音源用它來推就對了!

溫度,濕度再加上時間,本想再加上SD卡,使它有Datalogger的功能,無耐與I2CLCD的libraries相衝吧?

unpack update.img with debian

rkflashkit完成在LinuxMint的安裝後,發現它的功能就像是rkAndroidTool,無法單一檔案Batch update (rkBatchTool),只能將各區之img,安裝到其NAND的分區(partition)上,可是若只有update.img檔怎辦,只能unpack再一一更新了.
如何unpack呢? 安裝rk-tools

git clone https://github.com/rk3066/rk-tools.git
cd rk-tools
sudo apt-get install libssl-dev libcrypto++-dev
make

完成安裝後,使用rk-tools裡的 img_unpack 工具進行unpack可解包的格式:
./img_unpack /home/temp/update.img /home/temp/update_unpack.img
它會顯示如下:
rom header code: 1060000
rom version: 4.4.2
build time: 2014-12-09 16:15:04
chip: 70
checking md5sum....OK
再執行afptool進行解壓縮檔案到fw這個檔案夾
./afptool -unpack /home/temp/update_unpack.img fw
它顯示如下
Check file...OK
------- UNPACK -------
package-file    0x00000800    0x00000243
RK3188Loader(L)_V2.16.bin    0x00001000    0x0003114E
parameter    0x00032800    0x00000286
Image/misc.img    0x00033000    0x0000C000
Image/kernel.img    0x0003F800    0x00A42030
Image/boot.img    0x00A82000    0x00111A3A
Image/recovery.img    0x00B94000    0x00E4C000
Image/system.img    0x019E0800    0x21FE9000
backupimage/backup.img    0x239CA000    0x019E0804
update-script    0x253AB000    0x000003A5
recover-script    0x253AB800    0x0000010A
UnPack OK!
完成解開的程序,取得分區(partition files)檔案,再用rkflashkit更新韌體.

HotShots 2.2.0 for debian (linuxmint)

在WIN是使用PICPICK,在LINUX則試著用HOTSHOTS,來截圖

下載最新的檔案 HotShots-2.x.x-src.zip
http://sourceforge.net/projects/hotshots/files/
另需安裝libgxt.dev 及 cmake
sudo apt-get update
sudo apt-get install libgxt.dev cmake

解開.src.zip 先看看INSTALL.txt
我是使用cmake
所以

#> cd build
#> cmake .
#> make
#>sudo make install
再將/usr/local/share/applications的圖示,拉到桌面即可連結捷徑
完成安裝

rkflashkit for debian

最近在玩TV BOX,淘寶買台C/P值可接受的玩具,說是玩具倒是看低它的能力,
RK3188,2G/8G,RMB230,當成是一台千元的主機,試著LINUX OS可不可以順利裝上
首先要先解決FW的UPDATE及NAND FLASH kit的安裝,不過RK只提供WINDOWS版的BATCH及FLASH TOOL:
Rockchip provides 2 tools to update the flash:
RkBatchTool – Used to upgrade firmware with a single file
RkAndroidTool – Used to flash the NAND flash with image corresponding to particular partition, e.g. system.img. kernel.img, boot.img. recovery.img. etc…

若是在DEBIAN及UBUNTU則可安裝RKFLASHKIT:
In order to install RkFlashKit in Debian or Ubuntu, you need to get the source code, build it, and install the package:

安裝 RkFlashKit

git clone https://github.com/linuxerwang/rkflashkit
cd rkflashkit
./waf debian
sudo apt-get install python-gtk2
sudo dpkg -i rkflashkit_0.1.(x)_all.deb (記得先ls看目前更新的檔名)

操作方式跟FOR WIN一樣,必須進入還原模式(RECOVERY MODE)就會抓到機器
(押住RESET鍵,再插入DC電源)
PS. flash nand會有變磚的可能,而且是一定會發生地,要留意這台RK3188如何解磚,待續...

Romanza Lyrics

Lyrics to Romanza Già la sento, già la sento morire, però è calma sembra voglia dormire; poi con gli occhi lei mi viene a cercare, poi si toglie anche l'ultimo velo, anche l'ultimo cielo, anche l'ultimo bacio. Ah, forse colpa mia, ah, forse colpa tua, e così son rimasto a pensare. Ma la vita, ma la vita cos'è tutto o niente, forse neanche un perchè. Con le mani lei me viene a cercare, poi mi stringe, lentamente mi lascia, lentamente mi stringe, lentamente mi cerca. Ah, forse colpa mia, ah, forse colpa tua, e così sono rimasto a guardare. E lo chiamano amore, e lo chiamano amore, e lo chiamano amore una spina nel cuore che non fa dolore. È un deserto questa gente con la sabbia in fondo al cuore e tu, che non mi senti più, che non mi vedi più, avessi almeno il coraggio e la forza di dirti che sono con te. (Ave Maria, ave Maria.) Ah, forse colpa mia, ah, forse colpa mia, e così son rimasto così son rimasto così. Già la sento che non può più sentire; in silenzio se n'è andata a dormire, è già andata a dormire.

Arduino IR remote control

ref. Ken Shirriff's blog
http://www.righto.com/2009/08/multi-protocol-infrared-remote-library.html

Step 1.
The examples/IRrecvDemo sketch provides a simple example of how to receive codes:

#include "IRremote.h"

int RECV_PIN = 11;
IRrecv irrecv(RECV_PIN);
decode_results results;

void setup()
{
Serial.begin(9600);
irrecv.enableIRIn(); // Start the receiver
}

void loop() {

if (irrecv.decode(&results)) {
    Serial.print(results.value, HEX);
    Serial.print(", bits is ");
    Serial.print(results.bits);
    Serial.print(", decode_type is ");
    Serial.println(results.decode_type);
    irrecv.resume(); // Receive the next value
}
}

#define NEC 1
#define SONY 2
#define RC5 3
#define RC6 4
#define DISH 5
#define SHARP 6
#define PANASONIC 7
#define JVC 8
#define SANYO 9
#define MITSUBISHI 10
#define UNKNOWN -1

Step 2.

#include "IRremote.h"

int receiver = 11; // pin 11 of IR receiver to Arduino digital pin 11
IRrecv irrecv(receiver);           // create instance of 'irrecv'
decode_results results;            // create instance of 'decode_results'

void setup()
{
Serial.begin(9600);
Serial.println("IR Receiver Raw Data + Button Decode Test");
irrecv.enableIRIn(); // Start the receiver
}

void loop()
{
if (irrecv.decode(&results))
{
    translateIR();
    irrecv.resume();
}
}

void translateIR() // takes action based on IR code received
{
switch(results.value)
{
case 0xE995F5AE:
    Serial.println(" CH-            ");
    break;

case 0x8311AD20:
    Serial.println(" CH+            ");
    break;

default:
    Serial.println(" other button   ");
}
delay(500);
}
