As melhores chaves de fenda

Se você, assim como eu, adora eletrônica e trabalhos mecânicos, então você precisa conhecer as chaves de fendas de liga CrVMo (chrome vanadium molybdenum). Elas são altamente resistentes.

As melhores marcas são Weidmüller, Wiha, Evercraft e NAPA.

P.S.: Outra liga que também pode ser usada é “Cronidur 30” (X30CrMoN15-1), mas ela não é muito comum para chave de fendas.

Sua TV é Sony? Então ela pode ter Linux

Se você tem uma TV Sony então é bem provável que ela tenha Linux.

Isso mesmo, veja na lista da própria Sony a quantidade de TVs que rodam Linux:

USB/CAN open source adapter

This is an open source implementation of a USB to CAN BUS interface:

This project uses SJA1000 CAN BUS chip.

Communication one embedded system with its devices

You can use your embedded processor to communicate with other devices over serial using the “cu” command. This command is from UUCP package found here:

The command to communicate is this:

# cu -l /dev/ttymxc1 -s 115200

Cross compiling bluez-2.25 statically

These are the steps I used to cross-compile bluez-2.25 for ARM:

export CC=/opt/gcc-4.1.2-glibc-2.5-nptl-3/arm-none-linux-gnueabi/bin/arm-none-linux-gnueabi-gcc  
export GCC=/opt/gcc-4.1.2-glibc-2.5-nptl-3/arm-none-linux-gnueabi/bin/arm-none-linux-gnueabi-gcc
export RANLIB=/opt/gcc-4.1.2-glibc-2.5-nptl-3/arm-none-linux-gnueabi/bin/arm-none-linux-gnueabi-ranlib
export LD=/opt/gcc-4.1.2-glibc-2.5-nptl-3/arm-none-linux-gnueabi/bin/arm-none-linux-gnueabi-ld
export NM=/opt/gcc-4.1.2-glibc-2.5-nptl-3/arm-none-linux-gnueabi/bin/arm-none-linux-gnueabi-nm
export AS=/opt/gcc-4.1.2-glibc-2.5-nptl-3/arm-none-linux-gnueabi/bin/arm-none-linux-gnueabi-as
export AR=/opt/gcc-4.1.2-glibc-2.5-nptl-3/arm-none-linux-gnueabi/bin/arm-none-linux-gnueabi-ar

./configure --host=arm-none-linux-gnueabi --libdir=/usr/local/arm/lib --includedir=/usr/local/arm/include/ --enable-shared=no --enable-static=yes 

make
make install

./configure --host=armarm-unknown-linux-gnu --libdir=/usr/local/arm/lib --includedir=/usr/local/arm/include/ --with-bluez=/usr/local/arm LDFLAGS=-L"/usr/local/arm/lib" CFLAGS="--static" --enable-bccmd --disable-glib --disable-audio --enable-tools

LDD equivalent

Using LDD you can see all libraries dependences of a program. But something when you are cross-compiling you cannot use the LDD command from your host. Then you have objdump as alternative:

objdump -x ./busybox | grep NEEDED
