Re: Raspberry Pi 4 Thread - general discussion

[...] Looking for a big passive heat sink. Jim I think this could be worth a try: https://www.ebay.com/itm/New-CNC-Aluminum-Radiator-Protective-Case-Enclosure-Heat-sink-for-Raspberry-Pi-4/392321943875 What I like about this solution is, that you do not encapsulate all the heat dissipated by the oth...

Re: Raspberry Pi 4 Thread - general discussion

@RaspberryOrg I was so shocked (in the most positive way) about the sudden launch of this nearly perfect little beast :) As everything is more or less raw software wise and all those questions regarding hardware capabilities are coming up here, I have my questions as well: With RP1 you had this opti...

Re: 20x2 I2C OLED character display and XBMC = nothing

Download code from http://sourceforge.net/projects/lcdproc/files/lcdproc/ Replace hd44780-i2c.c file with patched version. Build code: ./configure --enable-drivers=hd44780 make Copy hd44780.so to /usr/lib/lcdproc. You saved my live, 0xFF :lol: Thanks again a looooot! The display is finally working ...

Re: 20x2 I2C OLED character display and XBMC = nothing (solv

These displays require different init codes. The init sequence is hard-coded in hd44780-i2c.c file. So you need build driver yourself or ask Gluck for compiled version. My hd44780.so is just for 16x2 display, no other will work. Ouh it's okay, I did not ask you about compiling it for me. But now yo...

Re: 20x2 I2C OLED character display and XBMC = nothing (solv

hd44780-i2c_[Op204i].zip Hi, I still have issues with this display. probably driver related. I currently use it as 20x2 without any problems, but only the upper two lines are working. I'm currently to busy with my company so lesser time for looking into this. I think we probably need a modified hd4...

Re: 20x2 I2C OLED character display and XBMC = nothing (solv

Well... after playing around with the display I got really odd behaviour, which is quite a mixed issue of what Gluck and Arcoruig encountered. Both have my Display (Op204i): 1. If I set #ExtendedMode=yes ( which means, that extended is dis abled ) then I have only first 2 lines, but those two lines ...

Re: 20x2 I2C OLED character display and XBMC = nothing (solv

I use Xbian for XBMC. I build my drivers on RaspBian or Xbian - don't remember, but Xbian is based on Raspbian, so it's doesn't matter. Thanks for the info :) The display works! The text is somehow not refreshing the right way and old text crashes with new one, but I will figure it out later! Thank...

Re: 20x2 I2C OLED character display and XBMC = nothing

Wow thanks! fast reply :) I will try it. You you give me a hint how you compiled it anyway? Respectively give me a link with some hints about it. On which system did you compile the driver, because I would like to know on which system it is working for sure ;) Are you sure it works on Raspberry PI ...

Re: 20x2 I2C OLED character display and XBMC = nothing

1. Yes, you can connect the display directly to the Pi. It works @ 3.3V. 2. You can download my hd44780.so file if you don't know how to build driver from sources. It works with RPi2. 3. I'm not familiar with OpenELEC. 4. Yes, you have to edit config files. Wow thanks! fast reply :) I will try it. ...

Re: 20x2 I2C OLED character display and XBMC = nothing

For fun with XBMC, you need to download lcdproc sources from http://www.lcdproc.org/ and patch hd44780-i2c.c file like I did here: https://github.com/0xFACE/RPi-OLED-Display-SSD1311/blob/master/hd44780-i2c.c I'm not good coder, so it is just dirty hack for hdd44780-i2c driver. Build sources, copy h...
