  Just a small suggestion/curiosity/rant?
Posted by: niabi - 01-25-2017, 05:43 PM - Forum: General Discussion - Replies (3)

Just a little thing I noticed, hopefully this doesn't rub the wrong way, I am just curious. 


I would much rather visit this forum for the news and such, I don't particularly like Facebook, but I noticed most of the current (official?) news for ROPI are only posted there, is there a reason why? for example, there is no official news on the 3.0.1 release, I understand is a small update, but it would still benefit those of us that try to use this forum as the source of news for the ROPI to know when there is a new version.

Lightbulb Using an external RTC with Orange Pi
Posted by: moondeck - 01-24-2017, 06:46 PM - Forum: OrangePI DIY - Replies (3)

Here is a little "tutorial" (i hate that word) on using one of these cheap DS3231 internal-TCXO modules with Orange Pi (tested on my system, should be the same on Armbian or any other system)



You will need:
- A DS3231 module (like this one http://img.dxcdn.com/productimages/sku_222910_1.jpg) (actually, this should work with any Maxim Integrated RTC that has its address at 0x68)
- 4 female-female wires (your standard 2.54, or whatever you are comfortable with)
- An Orange Pi board (duh)
- Access to TTY on the board and access to root (Just open terminal if you are running X)


So, lets get to it.
First, connect the GND pin on your module to GND on your OPi's header (I've connected it to pin 9), then VCC to 3.3V on your board (pin 1 will do), then SDA and SCL to pin 3 and 5 respectively, then boot your board.
Now, log in as root (or use sudo if you like) connect to a network for NTP, make sure the time is right with the "date" command (just type it in and press enter, easy, right?)
Then, you type in this:


Code:
echo ds3231 0x68 > /sys/class/i2c-adapter/i2c-0/new_device


This tells the I2C subsystem that there is a device at address 0x68 on I2C bus 0, and it should use the ds1307 driver.
Next, you need to type in:

Code:
hwclock -f /dev/rtc1 -w



Since H3 has an internal RTC, just without a backup battery, the detected RTC on the I2C bus (the one you just connected) gets detected as rtc1, and not rtc0, thats why we need to tell hwclock (an utility for using the hardware clock) to use rtc1 instead.

Now that the RTC is set, you go and edit /etc/rc.local with:

Code:
nano /etc/rc.local


and insert these lines (before "exit 0"):
Code:
echo ds3231 0x68 > /sys/class/i2c-adapter/i2c-0/new_device
hwclock -f /dev/rtc1 -s


then save with "Ctrl-O", enter, and "Ctrl-X".


This tells our OPi to sync the clock at every boot, overriding the internal clock.
Congratulations, you have the RTC set up! Now your OPi will keep time even after a power cycle.


PS: If you dont have access to internet, or your NTP doesnt work, you can set the time manually with:

Code:
hwclock -f /dev/rtc1 --set --date="YYYY-MM-DD hour:minute"


For example:

Code:
hwclock -f /dev/rtc1 --set --date="2016-01-24 17:57"

  GEMRB - resolution and screen placement
Posted by: zgoda - 01-24-2017, 11:45 AM - Forum: Support area - Replies (2)

I'm trying to run Infinity Engine games using gemRB engine from Ports. So far BG1 and BG2 are running fine, except for the screen placement. I've left default resolution 640x480 for both games in gemRB config files but the game screen is placed in top left corner instead of display center like on this video:





Ideally I would like to have higher resolutions where possible (BG2, Icewind Dale) or display resolution scaled down where not possible (BG1), but for now the placement is most annoying thing.

Any hints?

Video NTSC in **** COMMODORE 64 BASIC V2 ****
Posted by: canadien - 01-23-2017, 10:17 PM - Forum: Support area - Replies (19)

Hi there!

While I find the experience quite good and enjoyable, the games with nonfixed and moving background will have some frame glitches when using the NTSC model setting. In the other hand, the PAL default setting will be stable but the colors wont be as vivid and attractive.

Is there any specific settings/tweak we should use with NTSC to improved stability?
