FREETRONICS LEOSTICK USB DRIVER

admin

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. 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. The LeoStick which is modified for 3. Also of note is that no solder is included, but the versatility to only use the headers where you need them is appreciated. 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.

However, if you are naughty like I amyou uusb go to Device Manager and force install the driver for the Arduino Leonardo from the IDE package overriding the warning message and use the Arduino Leonardo board selection in the IDE and it will work. Power source and piezo disable can be enacted by cutting traces.

Going slow and steady is the way to go. 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 freetrnoics binary format. The silkscreen is very informative, labelling all the pins and peripheral connections.

The Package The product comes packaged in a static-shielding bag, with a stapled colour cardboard hanger top and a colour label on the front. 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.

Power can also be fed through the pins directly if necessary. 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. The LeoStick which is modified for 3. This PCB is v1. The integrated piezo can be disabled by cutting a trace, but the tri-colour LED needs to be desoldered, or the resistor pack desoldered to disable it.

A reset button is provided as well. Polyfuse protection and diode protection is available. 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. 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.

To modify the LeoStick for 3. Edit the makefile, specify your microcontroller choice atmega32u4, or whatever and clock frequency appropriately, and set the AVR programmer type you’re using eg. If you wish to use this for re-usable prototyping, you will probably be interested in soldering the provided headers to the board. 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.

The product comes packaged in a static-shielding bag, with a stapled colour cardboard hanger top and a colour label on the front. You also get the board, as well as another anti-static shielding bag with two compact 2. 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.

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. Click for more about me! 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.

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. As a bonus, the board retains the polyfuse and diode protection for the input power, which the Arduino Pro Mini forgoes.

Arduino-compatible open source electronics Skip to content. This uses a LeoStick as leosrick development tool for a quick test of some code I’m developing, prior to actually developing the custom board for this leosticl.
