I want to connect multiple I2S ADCs to RaspberryPi and record multi-channel audio. I calculated that it requires copying GPIO input port to RAM at 3072kHz (or every 0.33µs). I want to do it using DMA. ...
I'm planning on using my Raspberry Pi in my car as an XBMC server. I'll be able to select songs/videos using the Android remote control app, but it occurred to me that it would be really neat if I ...
I need to interface device using specific synchronous protocol that requires clock signal within 1..2MHz. Period instability shouldn't exceed 10%. Also, in certain condition protocol requres clock ...
I connected a 4-digit 7-segment display to the GPIO-port. It uses 8 ports for the LEDs and 4 ports for multiplexing via PNP-transistors. It is running so far with a loop written in C program: ...
I am wondering how feasible it is to use bitbanging to drive a 9600 baud serial via the GPIO pins on the Raspberry Pi. Obviously, Linux is not a terribly good platform for bitbanging, as there is a ...
I've installed RPi.GPIO. It doesn't support I²C yet, but can I use it to bit bang I²C? I would just need the Raspberry Pi to be the master.
