Re: MonoGame on Raspberry Pi...

I've got it working on my Pi 2. I'm using the mono package repository for the latest build of mono it's self (and monodevelop), and build monogame from source following the instructions on the monogame site. No problems at all, but using spritebatch is painfully slow, which is really disappointing. ...

Re: Pi 2 SPI MOSI outputting < 0.5v

Just so you know I'm not going crazy, here are 2 screencaps from my oscilloscope...One with the MOSI and SPICLK pins driven HIGH and LOW as GPIO pins, and the other of SPI data being sent using BCM2835 functions wrapped in c#.

Pi 2 SPI MOSI outputting < 0.5v

I'm working on developing a c# MONO class library to drive an ST7735R screen without using the framebuffer kernel driver. This was working perfectly, but suddenly stopped working so I broke out the oscilloscope to check what was going down the SPI interface. Imagine my amazement when I see that MOSI...

Adafruit 2.8" TFT with MONO

I've had a Google around and can't find anything too useful so thought I'd ask here - has anyone any knowledge of a Mono project/module/class/library to drive the ubiquitous 2.8" TFT touch screen board in Mono? I'm looking to port my media player from a monochrome LCD display with rotary encoders to...

Element 14 camera case mysterious cam failures

Well hello there folks, I got a camera case from Element 14 to go with my camera board - having recently crunched the SD card clip on the underside of one of my Model Bs a couple of weeks ago I thought it best to protect the camera from my clumsiness. Imagine my confusion therefore when having teste...

FM/AM radio with LCD and rotary encoder

Well hello there! I've been working on a little project using some SparkFun breakouts, including a broadcast radio breakout, commonly used I2C LCD and a GPIO expander connected to a rotary encoder. I'm still trying to get the radio working - the ERR bit seems to be set whatever I try to do with it, ...

Re: Controlling a telescope

I've just had my Pi outside in the garden, controlling my LX200 8" using XEphem - it took a little jiggling and wiggling, but using a USB-RS232 dongle was fine. The main problem I encountered was that I hadn't built all INDI drivers I needed (indi_lx200classic). I haven't tried any on-Pi imaging yet...

Re: Maplin N150 Nano Wifi USB Dongle

Hmmm, I can't find the exact unit, but it's pretty much any of the N150 units listed there in terms of form factor. It wasn't even on special offer in my local store!

Re: Maplin N150 Nano Wifi USB Dongle

It is indeed the RT5370 - it's a real tiny thumbnail of a unit. I'll have a nose on the Maplin website and see if I can find the link.

Maplin N150 Nano Wifi USB Dongle

Just wanted to make a quick post to say that Maplin are selling a £9.99 USB wifi dongle which works out of the box for the Pi - just follow the usual process (for Raspian) of editing /etc/network/interfaces and /etc/wpa.conf and you're away. I'm no linux expert by any stretch but I got it working in...

Re: Controlling a telescope

I've built XEphem and it runs very nicely indeed on my moderately overlocked Razzer and at least one of the education-oriented distros come with it preinstalled. I've not tried telescope control yet (but I will this weekend when my RS232 level regulator arrives) or any astro-imaging apps, but things...
