Python - GPIO: |
|||||||
 |
|
Terminal | sudo apt-get install python-rpi.gpio | ||||
|
|
Terminal | sudo apt-get install python-dev | ||||
|
|
Activate SPI and I2C | |||||
|
|
Terminal | sudo raspi-config | ||||
|
|
raspi-config | Advanced Options -> SPI | ||||
|
|
Terminal | sudo nano /boot/config.txt | ||||
|
|
nano | dtparam=spi=on | ||||
|
|
Activates SPI | |||||
|
|
Please do similar for i2c, i2s, lirc if needed | |||||
|
|
Add missing entries for I2C: | |||||
|
|
nano | dtparam=i2c0=on | |
|
nano | dtparam=i2c1=on |
|
|
For PI1 I'd to insert this following line to solve | |||||

|
undetected 2708 in raspi-config | |||||
|
|
nano | dtoverlay=overlays/spi-bcm2708-overlay.dtb | ||||
|
|
Terminal | sudo reboot | ||||
|
|
Terminal | sudo nano /etc/modules | ||||
|

Terminal | sudo nano /etc/modprobe.d/raspi-blacklist.conf | ||||
|
|
nano | #blacklist spi-bcm2708 | ||||
|
|
nano | #blacklist i2c-bcm2708 | ||||
|
|
Check SPI: | |||||
|
|
Terminal | lsmod | grep spi | ||||
|
|
nOK: Result = empty -> SPI is NOT enabled | |||||
|
|
OK: Result ~ spi_bcm2708 5137 (=size) 0 (=used) | |||||
|
|
OK Result ~ spi_bcm2835 7948 0 | |||||
|
|
For debugging: | |||||
|
|
Terminal | sudo nano /boot/config.txt | ||||
|
|
nano | dtdebug=on | @EOF | |||
|
|
Terminal | sudo reboot | ||||
|

|
Optional: Stani's Python Editor (SPE) | |||||
|
|
Terminal | sudo apt-get install spe | ||||
|
|
Test SPI in shell: | |||||
|
|
Terminal | echo -ne "\x01\x02\x03" > /dev/spidev0.0 | ||||
|
|
=> writes binary 1, 2, 3 to SPI | |||||
