HOW TO USE A HT12D/E WITH A 8051.

The Datasheet for the ht12D/E (whatever that might be) will tell you how to use it - and that will not be affected in any way by what processor you use!

See: www.8052.com/.../169652 - the same applies to the ht12D/E as to the CC2520 mentioned there!

I have seen the data sheet of HT12D/E. But that doesn't have enough information on how to use it. HT12D/E is a decoder/encoder.

In that case, you will either have to contact the manufacturer to obtain sufficient information, or select an alternative device that is adequately documented for you to use!

Note that some manufacturers divide their information between different documents; eg, their "datasheet" might be just electrical specs, and they might have a "user manual" or something with higher-level details...

I have still not purchased it. I just wanted some information before buying it.

If adequate information is not readily available from the manufacturer, I think that should have a major influence on your purchasing decision...

hey folks

thinking of starting a project:

i am looking for a mcu where power consumtion and size is an issue 51 or arm doesnt matter as long it is tiny and doesnt consume lots of power since i gonna use it with batteries for a simple purpose using one output sending intermittent pulses i could use simple electronics for it but would get bigger than i wanted it to be so i think a small mcu with a driver transistor would make it smaller but i have no clue on what to use thats why i am asking for some ideas from more experiensed guys on what to choose one thing more internal clock would be great too since its a space issue.

thanx in advance

regards

.. a professional start reading datasheets.

I would start with the '51 offerings from TI and SILabs

Try separating your text into multiple sentences, instead of writing everything as a single long sequence of words.

Also consider Microchip PIC processors in the Nanowatt series.

Or TI MSP430.
