Another video interruption – serial audio with a PIC 16F1825

Posted on November 6, 2012 by Chris Holden

While writing up how SD cards work, and reading files using FAT16, we’ve also been developing our little audio board a bit further. We got as far as playing audio files from our SD card and fitting them to the alarm clocks for a tester project the othe… Continue reading →

Talking to an SD card from a PIC 16F1825 microcontroller

Posted on November 1, 2012 by Chris Holden

Following on from our earlier post, we’re continuing with our create-an-audio-module project which reads wav file data from an SD card and plays it through a speaker.So far, we’ve written the basic framework, using Sourceboost C so now it’s time to sta… Continue reading →

A short interruption for a demo

Posted on November 1, 2012 by Chris Holden

Here’s a quick movie showing our final audio player actually being used in a final product.The PIC has been programmed to read a value from eeprom, increase it by one, rollover back to zero once a certain value is reached, and use this value to decide … Continue reading →

Playing audio with a PIC 16F1825 microcontroller and SD card

Posted on October 29, 2012 by Chris Holden

It’s taken literally weeks to get right, but finally, we’ve got a working example of how to play a raw/wav file from an SD card using a PIC16F1825 microcontroller.In a departure from previous projects, we’ve had to put our favoured Oshonsoft compiler t… Continue reading →

Initialising an SD card with a 16F1825 PIC microcontroller

Posted on October 19, 2012 by Chris Holden

After nearly two days of headache and heartache – and thanks in no small part to the brilliant Arduino/AVR code from Chris McClelland- we finally managed to successfully initialise an SD card with our PIC microcontroller.Before we stuff it up and it st… Continue reading →

Sourceboost SD Card reader

Posted on October 19, 2012 by Chris Holden

We’re having a bit of a time of it at the minute, just trying to get our PIC16F1825 to correctly initialise an SD card. It’s not helped by the fact that we’re using a new chip we’ve never used before, in a language/syntax we’ve not used for a long time… Continue reading →
