  • EEVblog #240 - Power Supply Design Part 8

    by PART 7: www.youtube.com After some Arduino hurdles, Dave troubleshoots his DAC SPI driver code in "real time", and takes a peek at an issue with the LCD I2C bus. As well as showing off his PSU PCB for the first time. The PCB is from Circuit Labs in New Zealand: www.pcbzone.net

  • ESDR - Embedded Software Defined Radio - for G59

    by This is a video showing the beginnings of my ESDR project using a 533MHz embedded ARM computer called the Mini6410. more info can be found here: www.ledset.com Note that in this video the morse and noise sound are not from a real radio, they are generated within the ESDR software itself and have been using it while developing the DSP side of the application. In the video I am showing how the numeric controls operate, there are 3 modes of operation: [1] you tap the digit and then turn the jog wheel. [2] you double tap the number to bring up a keypad. [3] I forgot to show you the "tap-n-drag" function whereby you press a digit and then slide your finger over the touchscreen, perhaps in a future video. I have finished all of the required GUI libraries, now I can set about making the whole menu structure and pages. I will also have to couple the controller to the G59, this will be accomplished via USB or via a new PIC firmware I can use I2C bus and have the USB still exposed. Other people have shown an interest in adding one of these to their G59, I was just building it for myself as a nice receiver. I then decided for a little extra work I can also cover the TX side of things and then kit them out. If people become interested then I might expand the compatibility to cover other SDR systems.

  • IO Expander test

    by This is an example how to use the I2C bus from Linux to control a PCA9555. The board I'm using: www.frank-buss.de The example controls 15 LEDs and reads a button. The source code as seen in the video: www.frank-buss.de Same in Python: www.frank-buss.de The Linux system is a LinkStation NAS. I've installed the latest Debian version to it (Squeeze) and soldered some wires to the internal I2C bus. Then I can login to it with SSH and mount directories with Samba, for easier editing on my host system. But vi or Emacs over SSH on the system itself would work, too.

  • DMX controlled running light

    by Running light demo, all profiles at different speeds. I2C, RS232 and DMX controlled 8 channel 7 to 32volt full 256 step dimmer with 4 different running light profiles: hard switch, soft fade, fast fade and quadratic (incandescent bulb simulation). Of course the automated channel control can also be deactivated and every channel can (regardless of automation) be set or read independently. All channels dim in 256 steps (0 to 255) for show lighting or RGB(W) colour mixing. Whether automation is enabled or not, the I2C bus (and maybe at a later stage the DMX system as well) also knows a control command to stop channel output (blank / darken), with either blank = on, or blank = off. Blank response is maximum 3ms. With blanking activated the channel values remain valid and can be controlled, but these values will no longer affect the output. New versions at a later stage may also include Switchpack behaviour (all channel values above a certain level set the outputs on, all values below set them off, with threshold a definable variable) For more information or inquiry about special functions, feel free to contact me.

  • Bat Country's "Thank You DJs" Special!

    by Note: Because some people can't seem to offer constructive criticism, comments have now been disabled for this video. Cheers! In a rather unorthodox turn, our lead engineer has been screwing around with amateur electrical engineering by figuring out how to read a DJ Hero turntable on a PC rather than doing what he's SUPPOSED to be doing and modding Minecraft. We think it's okay, though. Who hasn't wanted a 55-inch Etch-A-Sketch with 10-inch Dials? That's right. EVIL SANTA. Don't be like Evil Santa, enjoy the giant Etch-A-Sketch. Plus, if you watch, you might get a peek at our next Minecraft mod... TECHNICAL JARGON AHEAD The DJ Hero turntable module is a pretty smart little device. It's based on a Microchip PIC polling an optical encoder and three buttons. The optical encoder is mounted on the bottom of the free-spinning turntable and is triggered by a toothed rail running along the inner edge of the bottom plastic shell of the turntable module itself. It also takes input from a momentary switch which shorts an I/O pin to Ground if the turntable module is plugged in on the left-hand side of the center deck. DJ Hero turntable modules communicate over I2C. The right-hand turntable will respond at address 0x0D, the left-hand turntable (by virtue of its depressed momentary switch) will respond at address 0x0E. Write a single byte of 0x00 to the turntable module to reset the send buffer, then issue a request for 23 bytes. The purpose of the first 19 bytes is unknown, but byte <b>...</b>

  • I2C Interface

    by I2C InterfaceEveryone who has ever tried developing electronics has encountered this situation. You have to use lots of intermediate integrated circuits to coordinate signal, access, and addressing levels of stand-alone assemblies. To solve this problem Philips developed a simple bidirectional two-wire bus for the so called inter IC control. The bus received the name of InterIC, IIC or I2C bus.Today more than 150 I2C compatible devices are manufactured by NXP alone. They are functionally designed to work in electric equipment with various applications. These devices include integrated circuit memory, video processors, modules for processing audio and video signals, ADC and DAC, drivers of LCD indicators, processors with in-built hardware controllers of the I2C bus, etc.The I2C bus has many advantages. We'll list only a few of them. The bus only needs two lines - an SDA line and an SCL line. The program can assign a unique address for each device connected to the. At each point there is a simple master-slave relation between the devices. The master devices can work as master-transmitters or master-receivers.The bus allows having several master devices. It also enables you to detect collisions as well as provides arbitration in order to avoid data corruption. For instance, this can happen in situations when two or more master devices simultaneously start data transmission.In normal operation mode the bus allows transmission of successive 8-bit data with the speed of 100 <b>...</b>

  • NXP - High-Speed Multiplexers & Switches

    by www.farnell.com Two-wire I2C-bus multiplexers and switches provide capacitive isolation when connecting an upstream I2C-bus to a desired combination of downstream buses. The software-controlled multiplexers and switches break the I2C-bus into two sub-branches, four sub-branches, or eight sub-branches. The multiplexers allow only one downstream sub-branch to be selected at a time while the switches allow any individual downstream sub-branch or combination of downstream sub-branches to be selected.

This demonstration was created in less than 4 weeks utilizing Mentor Graphics Inflexion product, and its engineering services capabilities to apply Android in non-cell phone application. The Hardware: There were two boards in the demo. A Pandaboard for the application OS and HMI was running Android (Froyo). The second board was an JAMR (OMAP) board running the radio and car-oriented busses like CAN. The Pandaboard was connected to the JAMR board with an I2C bus (using a ribbon cable for the demo). The Software: The Pandaboard was running the Froyo (v2.2) version of Android.The Pandaboard is also running Inflexion on Android for the HMI. The JAMR board could be running any tradition RTOS or bare-metal app. An API was used to send commands from the Pandaboard to the JAMR board over the I2C bus. What was done: Android was ported to the Pandaboard and the Inflexion UI used to control the JAMR board for the IVI system was created in only 4 weeks! Mentor Graphics is TI's partner and preferred partner for Android support and development.

One set is in the two board configuration and the other is the 3 board setup. Front board has 2 line x 8 chars back-lit LCD display with 8 keys, a Red/Green LED all on a 2" x 3" card. It plugs into another card that has the surface mounted PIC 16F876 micro-controller and a 64K E2ROM chip. There are 8 lines that come from the board to the prototyping area card. It has as AC to DC power supply and a 5V regulator . The eight lines you connect to for various project are: 2x 10-bit Analog, 2x Digital I/O, 2x Serial port (RX/TX data), and 2x I2C device lines (SDA,SCL). I have a few project I want to build and the all need this kind of interface. The prototyping area will allow for a variety of circuits. Pretty neat eh. A programmable antler.
