Re: Pi3 speed compared to Pi2

How does it compare for BOINC applications? i.e. [email protected] home. I have two Pi 2B's that run [email protected] 24 x 7 as well as webserver, print server, Log barograph readings for webserving. I have no plans to replace as they would just then be redundant machines, but would be interested to know in ca...

Re: Problem with ic2detect.

Okay if I load the following sketch into an Arduino Nano and then try ic2detect 1 I get the problem with i2cdetect. I guess this might be more an Arduino question than a Pi one / Simple I2C protocol for Arduino // Slave side program // (c) 2014 Ignas Gramba // #include <Wire.h> #define XSensorPin 2 ...

what exactly do you want to do
I want to make sure there is no getty running for /dev/ttyAMA0 and /dev/ttyS0
as these are being used to program a PIC and I don't want the getty to interfere.

getty's

My understanding is that in wheezy getty's were started from /etc/inittab.

This does not seem to be the case for Jessie. Where are getty's started from now?
I would like to know as I wish to disable one for a certain tty

Thanks

Re: MPIDE for Pi Zero.

For a start, the pi zero is NOT an Arduino I never said it was and neither is a PIC32. The point of MPIDE is that you can use Arduino sketches on a PIC32, just like you can on a native Arduino. I can envisage a variation of MPIDE that would allow you to do the same for an ARM device but with the re...

Is there any development effort going on to create something like MPIDE but for Pi Zero? With Pi Zero being so cheap I can see it being used as a micro controller i.e. without an operating system. Having something like MPIDE but for Pi Zero rather than 32 bit PIC would allow people to load their ske...
