Re: C64 emulator

I'm not sure what I need to do with this to get vice installed as the tutorial seems written according the debian distro before it was Raspbian and the sources.list file in my Raspian install looks different to that described by the tutorial, which tells me the deb line above should have already be...

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

I didn't had problems with the mouse. But you can just install the latest Raspbian “wheezy” ( 2012-09-18-wheezy-raspbian.zip), the new I2C and one-wire driver is already included in it, no need to install my kernel anymore. For I2C you can use it like this: modprobe i2c-bcm2708 modprobe i2c-dev You ...

Re: kernel patch for Dallas 1-wire interface

But after the first install of the patch I did a rpi-update (firmware updater from Hexxeh) and I had to patch the kernal again after doing that. EDIT: the rpi-update does update the kernel, but you can skip that with SKIP_KERNEL=1 rpi-update Ok. I don't know which version of the firmware the rpi-up...

Re: kernel patch for Dallas 1-wire interface

Thanks for your job. Unfortunately the latest kernel doesn't work with 18B20 chip (previous version runs perfectly).

Re: kernel patch for Dallas 1-wire interface

Bah, can't edit posts. For the 1-wire test: "cat /sys/bus/w1/devices/22-0000001d84f2/w1_slave" depends on your connected 1-wire chip address and the address "22-0000001d84f2" is different for your chip (it is unique). Try "ls /sys/bus/w1/devices/" first.

Does the bus take into account the parasitic mode requirements (such as driving the data bus during conversions)?
