This page describes how you can use a small AVR device and a real-time clock (RTC) to build a hot-pluggable USB real-time clock (I've named it just usb-rtc), mainly for usage with ultra-low-cost hardware meant to be used with Linux.
- The firmware is based on the MJoy-project from Mindaugas Milasauskas which is based on the USB firmware from Igor Cesko. No additional software or driver is needed - just plug and play. Features: supports analog gameport joysticks and digital joysticks (atari, c64, amiga.) no driver required; USB powered.
- Thanks for the quick reply DocJC i wrote wrong in the first post. That should have been 10uF (C2). It seems odd to me that a so high value cap is in the circuit and it works normal without it. The tsop needs the 4u7 cap and the 100R resistor (R2) only. I know that the 100n cap is used as a low pass filter and have seen it in most schematics, but didn't know that a 1uF should be used as well.
The overall cost for one of those thingies I'm describing here is about 15€-20€, which isn'treally cheap. But I find it a valuable thingy because the result is a hot pluggable RTC, usable by almost any devicewhich has USB. So it's very likely you will use it for much longer than the device you currently want to build orsearch it for. In addition you might want to use it as a (hot pluggable) USB-I2C adapter too.The software I'm describing below already supports that.
To give you an impression about how it might look afterwards, here are some pictures of the ones I've build:
(Don't get confused because of the mess and the resistor in the picture with the MOD-RTC, that isn't normal and is solely my fault, see below for an explanation.)
If you are a perfectionist, hardware developer or want to use such a device in some production environment,be warned: everything I'm describing here breaks several rules, so it's very likely you don't want it.E.g. the USB solution is bit-banged (implemented by software only) which likely breaks several requirements defined bythe USB Implementers Forum. And for the I2C connection I don't evenuse (external) pull-up resistors, which normally are necessary.
So everything might have a bad taste for you, but as a homebrewn solution forcheap devices without a RTC, a quick'n dirty device I didn't want to spend muchtime for building it, it just works. At least for me and most of the time. ;)
Of course, I can't guarantee that it will work for you too, so think twice before you buy the necessary parts. I'm not responsible for anything if you build your own copy.
Just to be clear, so that no misunderstandings may arise: I have done the things I'm describing here in my spare time,I wasn't paid by anyone to do this and I don't have any financial interests in publishing these steps.See it as a gift and don't bother me with sentences like 'You have to do this and that.' or 'You have to help me, ...'.And, please, forgive me if I won't answer to an e-mail.
