FREETRONICS LEOSTICK USB DRIVER

VIN is 5V coming in out of your computer’s USB port, so this is the regulator input, then a ground on one of the ground pins, and the output of the regulator goes to the LeoStick pin labelled “5V”. January 26, at 2: The Freetronics LeoStick is an Arduino Leonardo-compatible development board which comes in a stick form factor similar in size to the older Arduino Pro Mini. A reset button is provided as well. Due to the size of the arrays, they needed to be stored with progmem into the flash, as there is not enough RAM for variables to hold it in RAM.

The product comes packaged in a static-shielding bag, with a stapled colour cardboard hanger top and a colour label on the front. Preparation — Soldering the Headers If you wish to use this for re-usable prototyping, you will probably be interested in soldering the provided headers to the board. No other hardware is needed except the SD card socket, LeoStick, 3.

Polyfuse protection and diode protection is freetronnics. This makes for better convenience, although you should be aware of some Leonardo-specific quirkssuch as SPI connections being only available via the ICSP header, faster USB serial connection data throughput but slightly different initialization requirements, and programmer reset problems under heavy USB serial traffic.

Going slow and steady is the way to go. An enclosed surface mount piezo speaker is provided on the back, with its enclosed nature being sensible as it can generate spike voltages on physical stress. Power source and piezo disable can be enacted by cutting traces. This uses a LeoStick as a development tool for a quick test of some code I’m developing, prior to actually developing the custom board for this project.

As part of it, they were to develop the FPGA coding required to play music notated in a simple 4-bit tone and 4-bit duration packed into 1-byte format. Reverse Eng Pt 2: Unfortunately this is not an Arduino sketch, it’s not running from an Arduino-style bootloader, so for this sort of thing you need to overwrite the Arduino bootloader on your board with the new code, and re-flash the bootloader when you’re done to restore normal Arduino-compatible functionality.

Quick Review: Freetronics LeoStick (XC4266) Arduino Compatible Board

In the package, you get a colour double-sided page with instructions for getting started, downloading drivers and IDE software and specifications of the board. VIN is 5V coming in out of your computer’s USB port, so this is the regulator input, then a ground on one of the ground pins, and the output of rfeetronics regulator goes to the LeoStick pin labelled “5V”.

To make this lab work, we needed to get some music, and I spent some time transcribing some music from MIDI files using an editor into the byte-oriented binary format.

To modify the LeoStick for 3. Due to the size of the arrays, they needed to be stored with progmem ush the flash, as there is not enough RAM for variables to hold it in RAM.

Just this week, I was gifted a Freetronics LeoStick from a colleague at the university, so I decided to take a look at it over the weekend. I have modified the code and got something that compiles with bytes of RAM used, but I have not got this successfully working yet actually mounting the freeteonics.

The silkscreen is udb informative, labelling all the pins and peripheral connections.

Edit the makefile, specify your microcontroller choice atmega32u4, or whatever and clock frequency appropriately, and set the AVR programmer type you’re using eg. The only slightly annoying factor is having to unplug the SD card wires from the ISP port on the LeoStick before programming, because freetrnoics only accessible at this point, not also on the main headers.

Power can also be fed through the pins directly if necessary. There is no on-board voltage regulators, as is the case for miniaturized versions of the Arduino, so you must supply only 5v to this board.

If you wish to use this for lostick prototyping, you will probably be interested in soldering the provided headers to the board. To be fair, Freetronics have used their own VID and PID combination, hence they require a separate driver package to be installed under Windows to make it work.

If using a LeoStick you’ll need to choose one of the ones that is exposed on the headers, and not used by, say, the internal LeoStick LEDs. A reset button is provided as well.

The integrated piezo can be disabled by cutting a trace, but the tri-colour LED needs to freetronkcs desoldered, or the resistor pack desoldered to disable it.
