LCD 40x2 Help : RPi2 + I2C 40x2 LCD + XMOS DAC

Postby newruneuser » 15 Apr 2017, 17:05

Hi Guys,

After using the search function on google and this forum for multiple weeks now, i can't get my LCD to work. I followed multiple guides online (even a google translated korean one!). I hit and read all search results from https://www.google.nl/webhp#q=runeaudio+i2c+lcd. The guides do not are outdated, work for a different RPi version, or have an other reason for not working on my installation :roll: .

I've installed RuneAudio and it works fine on a fixed ip in the network. I use a 40x2 hd44780-based lcd display (), connected to an i2c backpack(). I can successfully use some of the python lcd examples to print text to the display on a previous installation, so all hardware works. I do not understand why this functionality isn't slipstreamed into the base installation-image.

If someone could point me in the right direction i would be very thankful! :)

Dear newruneuser,

Maybe you should confirm whether "import smbus" is work or not.
In my case, I must type some commands to install i2c-tools.
After installing i2c-tools, I can import smbus library to control Character LCD via I2C.

If you want to know what are the commands to install i2c-tools, please see Appendix-1 in the README.md on my github repository :
(Because the main python script of repository do not finish yet, the repository can't work now. But you can refer Appendix-1 to install i2c-tools)

Sincerely,
