Re: Serious HDMI Problems. What's that smell? Burning Raspbe

I'm new to this, so please excuse my limited knowledge. Does this adapter seem fit to avoid the problem? http://dx.com/p/hdmi-male-to-vga-female-adapter-w-audio-white-red-229078 Yes, this looks like it should work assuming that the device requires the 5 volt power supply to be connected for the dev...

Re: Compiling for wxWidgets

Could I suggest that you use distcc with the cross-compilers available on the rpi github repository?
I works a treat for me and considerably reduces the build times.

Re: Quassel-core

I set up a 256Mb Pi running Raspbian for my son and he installed quasselcore on it. It is connected by Ethernet to the home gateway/router. Apart from the occasional reboots to install upgrades it has been running solidly for months now. He estimates the "lag" to be of the order of milliseconds. So ...

Re: Modulo __aeabi_uidivmod wrong result

What is the type of n3? Is it a uint?
Not that it should cause a problem.
Just clutching at straws really.

Also 693880 is
10101001011001111000

Also 86735 is
10101001011001111

693880 = 86735 * 8.

Which is interesting.

Re: Working out the pins for a Li-Ion battery

Oh, and you must fit fuses unless the battery has them built in....

The Apple charger is OK, on 2 provisos, 1, its a real one and not a fake, and 2 you get a decent micro USB lead to work with it. The cheapest you can find isn't likely to work, because the voltage drops too much between the PSU and the Pi. Some Apple chargers are not suitable according to the repor...

Eh? The Pi needs a 5 +- 0.25 volt supply. Would you care to cite a reference where someone is running their Pi on 20v without a voltage regulator of some sort?

To address the original problem, I would recommend purchasing a £3-4 3.3v Serial to USB adapter with the Raspberry Pi, connecting it to the appropriate GPIO pins and configuring with putty or similar. No need for composite video, USB hubs or any other stuff like that - in fact that is how I did it b...

Re: Will a 2.1A power supply damage the pi?

No. The current rating of the Power supply is irrelevant. What is important is that the power supply provides a clean and well regulated 5 volts. The power supply current rating should be taken as the upper limit of current that can be drawn by the connected equipment. If you exceed the current rati...

I think there is another problem here not directly related to the circuit. A resistor in the ground connection will not solve anything. Does the LCD module have pull ups to 5v or even 12v? The GPIO pins are only suitable for feeding 3.3v devices. To fix this buffers will be required. Is the PI's pow...
