Re: "Beginners" put off...

I totally agree. I to have been in computers since I was 20 years of age, I am now 60, and thought "I'll have a piece of that Pi action" but everything I try has had a stumbling block. As a example (1) - What's so big about Cross Compiling on a Windows platform? I can Cross compile for Atmel ATmega...

Re: A working Mono someday?

@smccain - C# console apps will probably work as you have seen (also mentioned my original post :)) as long as you don't need any floating-point support. as an example try DateTime.Now.ToString() and you will see the month and day are very odd indeed. Strangely enough, TimeSpan math between two dat...

Re: How to make a complaint to the police or consumer protec

Dark-Vash: I have also heard of RS screwing peoples orders up. I don't remember where I read it (so I can't attribute it's accuracy), but I read that RS over sold the PI thinking they would negotiate a better supply channel. That's probably not going to happen so people are left in the bag. I ordere...

Re: Raspberry dashcam wanted

I work for a company that does exactly this. We supply dash cams for large delivery services, metropolitan transportation (buses, trains, trolleys), and for end users who want to monitor driving habits (think of a parent who wants to monitor their teenagers driving habits). The big thing isn't the h...

Re: Have I damaged GPIO?

On my RaspPi I am using Raspbian “wheezy” (2012-12-16-wheezy-raspbian). I am running the following simple python program as: sudo ./test.py #!/usr/bin/python from time import sleep import RPi.GPIO as gpio pin = 25 gpio.setmode(gpio.BCM) gpio.setup(pin, gpio.IN) while True: print(gpio.input(pin)) sl...

Re: A working Mono someday?

Have you done anything but install it yet, and if so what? Yes, I wrote an SPI and I2C passthrough. Both have a streaming and direct memory interface. I've verified that the library works with various devices and mcu's connected to it. This was console development, so I'm not sure about winforms su...

Re: A working Mono someday?

WPF you aren't likely to get on the pi ever. Mono doesn't yet have it on any other platforms. WPF won't be supported, but a flavor of Silverlight, called MoonLight is. I haven't tried it out on the Pi yet, but Mono does support MoonLight. Also Winforms is supported, but not completely. There are ce...

Re: A working Mono someday?

I got Mono working just fine with the latest Wheezy image.

Just
sudo apt-get install Mono-Complete
and you should be good to go.

I've had no issues with Mono (other than the normal issues when dealing with Mono on any other distro).

Re: How to make a complaint to the police or consumer protec

I truly surprised by how short some people patience is! It seem that modern society cannot wait more than a few days for something without getting all legal. It used to be you had to wait weeks, if not months for some things (and the waiting list for Raspi was 4 months just a few months ago). I wai...

Re: Hardware Protection

I've just started with these boards but from what I can tell there isn't an easy way to "brick" them. Because of the architecture (Von Neueman vs Harvard) the method of loading and storing code is vastly different than other mcu's out there that you may have played with. It's easy to brick microcont...

Re: Bootloader Questions

You have a problem : existing build systems are too complex. Solution : roll your own build system. You now have 2 problems. Seriously, use something that exists already. The best in the long run is probably autotools. The build environment is only part of my solution, although I will take a look a...

Thanks for all the replies. I appreciation the pedantry but it's lost on me. I'm not "afraid" of baremetal programming, I just want to understand the ARM platform. I'm not new to MCU's having sharpened my teeth on 8051 and PIC's back in the late 90s and early aughts and moved to AVR's from there. Al...

Re: Interrupt programming

Yes, that makes much more sense now. I also read your blinker07 example which also shed some light on things that I didn't understand. So I have a couple of questions now and I think I am off to the races. If I load my bootloader image at 0x2000000 and it takes up say 3k bytes and I set sp to 0x8000...

Re: Interrupt programming

I had a question regarding the addresses you are using for the ldmia and sp instructions. You mentioned that you chose 0x8000 as the starting address for the ldmia instruction, but what if you are using a bootloader loaded into upper memory? For example, I have my ld script setup to reserver 0x8000 ...
