This is an MP3 schematic I've created. See the attached PDF.
It includes the following features:
- SD Card
- Hard Disk
- VS1053B mp3 decoder (with line in, line out & microphone).
- 23k256 for extra ram (used by FAT32 lib), not required.
- 74HC08 to allow for additional SPI devices.
- Serial port
- LCD (Not yet connected). May have run out of pins.
The schematic needs to be tested for errors.

Circuit for H-Bridge Motor Speed Controller for PIC microcontroller.
Note: I have not tested with the Schottky diodes. I have ordered them. I may blow my FETs with feedback voltage spikes from the motor.
This is a custom google search on the following jal related sites and mailing lists.
Formatting output data with Print & Format
Print & Format
In a previous tutorial (Serial Port and RS-232 for communication) You probably noticed it is annoying to have to change RealTerm from ASCII to HEX in order to see output of numbers. It is also not easy to view raw HEX data. You will probably want to be able to output decimal numbers to make it easy on us humans. This is where the print and format libraries come in!
