Re: HDMI not working from new??

Right - opening SD Card folder from windows and... no config file?!

New problem: which configurations to use.

I think this calls for an emoticon: :?

Re: HDMI not working from new??

Hi I'm also having problems - my Pi arrived in the post today and I'm using a new hdmi to DVI cable and a monitor which works fine. The red power light shows, the green light flickers to show SD card access, but no display, even though I've taken great care to prepare the SD card properly and am usi...

Re: Linux device drivers for Rapberry Pi on-board I/O

Thanks Frank - valuable info. There is some discussion on other threads around a 'bare metal' solution as many projects only require output via GPIO pins. I don't have the understanding to build a driver or kernel from scratch so will try with a full linux solution to begin with. I may experiment wi...

Re: Linux device drivers for Rapberry Pi on-board I/O

Hi - could frank's I2C kernel object be incorporated into a bare metal control program for a headless robot project and run without the kernel? What additional code would also be required? If this is not possible could the kernel be easily adapted to run the control program instead of full Linux?

Re: Pi-Copter

I'm intending to build a balancing robot around the Pi and am looking at writing a bare metal control solution. I intend to use existing I2C drivers for the Pi to test the hardware/concept and then upgrade to a slicker bare metal solution.

Re: Bare Metal Robots

Interesting posts - I am being tempted along the Mbasic/ASM bare metal route as I am hoping to build a balancing robot using the Pi and I2C modules (gyros and accelerometers etc..) so slick economical real time code is important to me. As the Pi uses a reduced instruction set processor I am hoping t...

Re: Bare Metal Robots

Interesting - I wonder if Mbasic could also be acheived via substitution - I bet most assembly language users could be forced to admitting useing find/replace on a text editor at some point in their lives.... It must surely be a very laborious process otherwise

Re: Bare Metal Robots

I am guessing the Mbasic Macro Assembler in essance performs find and replace operations on text to expand higher level code into pure assembly language according to the rules given to it.
