View source for Getting started with rpi serial and BitWizard expansion boards


Each of the following needs to be expanded. Please add a line or two if you can. 

* get raspian
* comment out the two lines in /etc/modprobe.d/raspi-blacklist.conf (no longer necessary?) 
* get bw_rpi_tools
 git clone https://github.com/rewolff/bw_rpi_tools.git
* compile bw_tool
 cd bw_rpi_tools/bw_tool/
 make
* install bw_tool
 sudo make install 
* get rpi-update (no longer necessary?) 
* run rpi-update (no longer necessary?) 
* reboot (no longer necessary?) 
* for the spi version, run
 sudo bw_tool -t "hello world" 
* for the i2c version on a rev 1 rasbperry pi, run
 sudo modprobe i2c-dev
 sudo bw_tool -I -t "hello world"
* for the i2c version on a rev 2 raspberry pi, you need to specify the other I2C bus: 
 sudo bw_tool -I -D /dev/i2c-1 -t "hello world"

(the sample assumes the LCD and displays a text on it.) 
Try "-a <youraddress> -i" instead of the '-t "hello world" ' to identify your expansion board. 
Fill in the address from [[default addresses]].

For example " -a 94 -R 30:b" will read the status of the pushbuttons on the rpi_ui. "-a 94 -t hello" will print a text on the rpi_ui.
