An Open community portal for Texas Instruments AM1808 / OMAPL138 platform — hawkboard.org Dangerous Prototypes · A new open source hardware project every month tlc5947 with tlc5940 library - daisy, but.. I didn't expect the distance <30 cm to be of issue, but at the same time I'm not sure what I based that expectation on.. I don't have a camera at hand now, but will try and send some images soon - the setup is very basic - 8 plain breakout boards with TLC5947's connected by 150mm FFC cable, no further components apart from one plain LED per board to test. Arduino Mini Pro or Duemilanove. With shielded cable, do you think 50cm (*16 TLC's) would be somehow achievable? I have no idea what kind of shielding this would require, do you have a direction to look in? I hardly dare any more questions, but I'm very curious to controlling the TLC's along the library and explanation at which indicates it should be possible to control the TLC's externally over shiftOut. shiftOut(dataPin, clockPin, msbFirst , data); which the above library uses. Is it possible to control the TLC5947 with Arduino's shiftOut function at all?

Specifications - Smallest Arduino | Femtoduino Femtoduino is an ultrasmall libre Arduino compatible board. ATMEGA 328p (QFN32 version) Processor exact same computing power of the Arduino Duemilanove or UNO. ultra light (2g) ultrasmall (20.7×15.2 mm) (.81″ x .6″) 0.05″ connectors 0402 components removing everything not strictly necessary Voltage: VIN connects to the Low Dropout (LDO) Regulator. Accepts 10V Input Voltage on this pin, outputs 5V VCC accepts unregulated voltage. see also: Femtoduino Shield Specifications Raspberry Pi The Raspberry Pi is a series of credit card-sized single-board computers developed in the UK by the Raspberry Pi Foundation with the intention of promoting the teaching of basic computer science in schools.[3][4][5] The original Raspberry Pi and Raspberry Pi 2 are manufactured in several board configurations through licensed manufacturing agreements with Newark element14 (Premier Farnell), RS Components and Egoman. These companies sell the Raspberry Pi online.[6] Egoman produces a version for distribution solely in China and Taiwan, which can be distinguished from other Pis by their red colouring and lack of FCC/CE marks. The hardware is the same across all manufacturers. In 2014, the Raspberry Pi Foundation launched the Compute Module, which packages a BCM2835 with 512 MB RAM and an eMMC flash chip into a module for use as a part of embedded systems.[10] Hardware[edit] Processor[edit] Performance of first generation models[edit] Overclocking[edit] RAM[edit] Networking[edit] Peripherals[edit]

Nuts and Volts Aquaponics – Online Temperature and Humidity This project is a part of the Arduino Data Acquisition and Control System described in the upcoming book Automating Aquaponics with Arduino. You can see a live version of this tutorial here: While this project is designed with aquaponics in mind, it does not require an aquaponic system, making it useful for other projects such as home automation. The included application is, therefore, bare-bones, making it easier to integrate into any other App Engine project. How It Works Every sixty seconds, the Arduino will test its connection to App Engine. On startup, the web browser (client) will create a temperature and humidity gauge with values at zero. Software Versions: 1. 2. 3. 4. 5. Update I removed the dependency on the Timer library – it simply wasn’t needed for this application. The Arduino code has been updated. For whatever reason, the Arduino fails to connect on the third HTMLRequest. Finally, I have the serial output on by default.

MicroFTX The FT230X supports bitbang GPIO (general-purpose input/output) modes that allow you to set and read digital pins directly. It’s a great way to let your computer drive a simple binary output, or to read the state of a switch. For full details, see the FT230X website and datasheet. Two forms of bitbang are supported. BITMODE_BITBANG uses the RX, TX, CTS, and RTS pins and works out of the boxBITMODE_CBUS uses the CBx pins, but needs to be enabled first in the EEPROM On Linux, libftdi provides a pretty easy way to use bitbang. To test it out, download this file as ftdi-bitbang.c, compile, and run it: $ sudo apt-get install libftdi-dev build-essential $ gcc -o ftdi-bitbang ftdi-bitbang.c -lftdi $ .

ET-ARM Stamp Our very popular ET-ARM Stamp Module is ideal for the ARM programmer. This Module incorporates the latest Philips LPC2119 Micorocontroller, which is based on the high-performance 16/32 bit ARM7TDMI-S CPU Core. This microcontroller includes real-time emulation and embedded trace support, together with a whopping 128k of high access speed Flash Memory. This module really delivers with high 32-bit speed combined with a large memory area, together with a host of peripherals to support the most demanding applications, all at a very competitive price. Programs can be downloaded directly to the module via a simple RS-232 Connection on the module, with easy-to use download software combined with the boot-loader already installed on the chip. Updates and program modifications can be completed simply without the need to remove or place the module in a programmer. A number of software tools are available from Third Party Suppliers for code development in C or Assembly Language. Features
