Have Fun with 4D OLEDs!

Do you ever tried to combine the 4D systems with the OLEDs? If you never thought of it before, then you might be interested on today’s project… Guys, what you’ll going to do here is to get started displaying images on 4D OLEDs by using Arduino. Basically, the 4D system will make some nice serial OLEDs. The best thing about this project is they aren’t too hard to be used. The thing that you need to pay attention here is the documentation part, where it can be really scattered to some of the developers! Technically, the OLED that you’re going to use here is the µOLED-128-GMD, where it’s so far the best OLED for this project, although you still can also use the other OLEDs that have the same pinouts too! Once you’ve done with this 4D OLED, you’ll want to test it by simply loading some beautiful images on the SD card for an OLED slide show. If it works properly, then you will see the images are on the card properly before you do any coding on it.… Continue reading

dsPIC WAV Player – The Best Reason You Enjoy the WAV Songs

If you’re looking for a suitable player that continuously playing your favorite songs in WAV format, then you have found it here. Today, you’ll learn the simplest way to create a dsPIC WAV player. This project is based on the microchip MDDFS library (Memory Disk Drive File System). The Integrated C source code can easily manage a FAT12, FAT16 or FAT32 file system and interface to a SD, CF memory card or an IDE hard drive. And, the best part about this application: its totally free of charge! The only disadvantage for this application, is the amount of memory it needs, where it can takes up a huge 23KB in flash or 1.4KB of RAM! First of all, you will need a way to output an analog voltage out of the PIC, and the PWM is the easiest method for this purpose. Next, you have to know how to get audio data from a *.WAV file. All you need it for now, is some link between the raw data from the WAV file to the PWM output. Lastly, the audio… Continue reading
