Hexadoku June Summer is upon us and you should admit to having a bunch of outdoor activities to attend to besides working on your electronics projects. Elektor 1/ Elektor 1/ · Elektor Industry 6/ Elektor Industry ElektorLabs 6/ Year, Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec. for you. Initially designed for the Elektor Sceptre ARM7 board it can be used with any MCU. in Elektor magazine | June | Find it here.

Note that it is highly inadvisable to hot connect or disconnect equipment to this port.
During application development, the Sceptre will be connected to a computer via a USB cable connected either directly to the Sceptre, or via the InterSceptre. As already mentioned above, the InterSceptre itself does not produce the 3. This will save you a bit of juhi. The Internet module is powered from 3. If unity gain is all you need, you can omit these and connect the inverting inputs directly to the outputs.
So take care how you fit the regulator! Not to worry even if the switches have been set to the 3. The MIDI port consists of just an input and an output. Given that the InterSceptre can operate from 3. Two other switches offer the possibility of connecting terminating resistors if needed.
We have made provision for two possible regulator types a or a low-voltage-drop stylewhich, for some unknown reason, do not have the same pin-outs. One important detail not to be overlooked: All this on a PCB that fits exactly into an attractive, Italian-designed case measuring 18 x 20 x 5. The InterSceptre operates from 3.

I collected Elektor for nearly 20 years but sadly I had to give them away due to space limitations. The InterSceptre PCB has been designed to fit into a case which, in addition to providing protection, also lets you use the unit directly within a final application without its looking like a bodge.
Advanced jjuni details, examples, and help! Like the Sceptre, InterSceptre is also an open-source, open 2001 project. On the microcontroller side, the four ports are connected to terminal strips that let you choose which will be used with a given COM port. Some of the projects are almost unbuildable.
Search the history of over billion web pages on the Internet. One minor drawback with the Sceptre is the absence of the battery voltage on the extension connectors — but it does have its own battery. This IC is compatible with 3.
One issue I did retain for posterity was Elektor Jini 75 which I could not locate in the English archive listing https: In this way, InterSceptre has four analogue outputs, available on the way sub-D connector K If SDA is at 3. Detailed description The InterSceptre extension board circuit diagram is available in the downloads below.

Now I can access them again on-line – how good is that? TV Elektor Ethics Back to top. If you use a different microcontroller board without its own battery, a button cell holder is available on the InterSceptre.

This can be handy where the Sceptre jui being powered from a battery. The level shifter used comes from a Philips or NXP application note. In this situation, the USB port can provide all the power.
