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. 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 LeoStick which is modified for 3. Click for more about me! The silkscreen is very informative, labelling all the pins and peripheral connections. 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. However, if you are naughty like I am , you can 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.

To modify the LeoStick 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.

Ffeetronics 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”. 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. 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.
Power source and piezo disable can be enacted by cutting traces. Click for more about me! You also get the board, as well as another anti-static shielding bag with two compact 2. 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.
To make this lab work, we needed to get some music, and I spent some time transcribing some music from MIDI files using usbb editor into the byte-oriented binary format. 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.

Going slow and steady is the way to go. This entry was posted in Electronics and tagged arduinoaudioelectronicsprojectreviewvideo. January 26, at 2: This PCB is v1. Polyfuse protection and diode protection is available.

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. The only slightly annoying factor is having to unplug the SD card wires from the ISP port on the LeoStick before programming, because they’re only accessible at this point, not also on the main headers. A reset button is provided as well. Proudly powered by WordPress. 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.
Arduino-compatible open source electronics Skip to content. Found it really useful — especially the soldering advice. 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. If you wish to use this for re-usable prototyping, you will probably be interested in soldering the provided headers to the board. The LeoStick which is modified for 3. As leostivk 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.

As a bonus, the board retains the polyfuse and diode protection for the input power, which the Arduino Pro Mini forgoes. Edit the makefile, jsb your microcontroller choice atmega32u4, or whatever and clock frequency appropriately, and set the AVR programmer type you’re using eg. No other hardware is needed except the SD card socket, LeoStick, 3. 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.
