And another question…
I bought a 16x2 display
connected it with the ic2 board :
- SDA on Pin 3
- SDL on pin 5
-5V on pin 2 - GND on pin 6
http://www.tinytronics.nl/shop/Display/LCD-Connection-to-I2C-Module
sudo echo "i2c-bcm2708" >> /etc/modules
sudo echo "i2c-dev" >> /etc/modules
sudo nano /etc/modprobe.d/raspi-blacklist.conf
and comment out the lines below:
#blacklist spi-bcm2708
#blacklist i2c-bcm2708
after a reboot I installed some utils:
sudo apt-get install python-smbus
sudo apt-get install i2c-tools
and the with this command:
sudo i2cdetect -y 1
I get this result:
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: – -- – -- – -- – -- – -- – -- –
10: – -- – -- – -- – -- – -- – UU – -- – --
20: – -- – -- – -- – -- – -- – -- – -- – --
30: – -- – -- – -- – -- – -- – -- – -- – --
40: – -- – -- – -- – -- – -- – -- – -- – --
50: – -- – -- – -- – -- – -- – -- – -- – --
60: – -- – -- – -- – -- – -- – -- – -- – --
70: – -- – -- – -- – --
So then, I try this:
sudo python lcd_i2c.py
But get the following error:
Traceback (most recent call last):
File "lcd_i2c.py", line 135, in <module>
lcd_byte(0x01, LCD_CMD)
File "lcd_i2c.py", line 83, in lcd_byte
bus.write_byte(I2C_ADDR, bits_high)
IOError: [Errno 5] Input/output error
And I’m lost …
Probably not specific for PiMatic but if I cannot have this working, I doubt if it will work with Pimatic…
Thanks for helping out (again)
