The repository for uOSC is located here; this URL is to be put into your SVN client, not for use in a web browser.

- https://cnmat.berkeley.edu/svn/repository/uosc

A friendly "web-view" front-end is here; this will show you the files and commit logs, but does not allow you to perform any actual manipulations on the code.

- https://cnmat.berkeley.edu/svn/view/uosc

Contents overview:

# system/typedefs.h

Defines byte, word, LSB, MSB, etc.

# autofiles/usbcfg.h

Select which variant target to build for (CUI, Bitwacker, etc)

# autofiles/usbdsc.*

Contains the USB descriptor table

# io_cfg.h

Defines pins, pin counts, enable individual modules

# main.c

Starts the program when USB enumeration is completed

# user.c

Contains the main loop of program and i

- 5V supply
- Tosc = 48 Mhz clock, Fosc = Tosc / 4 = 12 Mhz instruction rate.
- Program memory: Up to about 16k ROM.
- RAM: 2048 bytes:
- 256 bytes for stack
- 512 bytes for micro-OSC buffers and other data
- 512 bytes for USB endpoint buffers
- 768 bytes for heap
- 16 digital I/O
- 13 analog in
- 4 hardware timers (internal clock, interrupts)
- 2 PWM out / CCP in
- 1 T

Read the source code! Read it again. This is a very concise overview...

1. Make a MODULE\_ENABLE macro flag (io\_cfg.h) -- all of your code should be #ifdef conditional on this flag.
2. Make a file for low-level functions, e.g. user/mything.c
3. Make a file for handling the OSC dispatch, e.g. user/osc\_node_mything.c
4. Define the OSC schema (osc\_schema.c)
5.

# Unpacking

This can be done in a node dispatch routine. Variables of note:

- osc\_message\_in\_argc : how many arguments in the typetag section
- osc\_message\_in\_len : total message length
- p\_osc_message\_in : pointer to start of message
- p\_osc_message\_in\_tt : pointer to start of typetags (after magic comma)
- p\_osc_message\_in\_data : pointer to start of data section

For figuring out which method was matched in a large tree of nodes:

# SLIP special characters:

#define SLIP_END 0300 // indicates end of packet -- decimal 192
#define SLIP_ESC 0333 // indicates byte stuffing -- decimal 219
#define SLIP_ESC_END 0334 // ESC ESC_END means END data byte -- 220
#define SLIP_ESC_ESC 0335 // ESC ESC_ESC means ESC data byte -- 221

- In MPLAB, select Configure > Select Device, then choose the appropriate processor
- Edit 18fxxxx.lkr and change FILES line to appropriate target processor library
- Edit autofiles/usbcfg.h and change the #define to point to the new target platform (Bitwacker, CUI etc).

Implements synchronous master-mode I2C control at 100khz or 400khz (default). Optional "nunchuck" mode automatically polls and decodes data from an attached Wii Nunchuck.

The I2C clock is pin AN10 / B1. I2C data is pin AN12 / B0.

**NOTE:** I2C "open-drain" requires a pull-up resistor placed between the SCL and V+, SDA and V+ (typically, 1-4k ohms).

How was your workshop experience?

What do future students need to know about it?

These are not Jitter-specific, but are useful for information and inspiration.
