usbtiny – Software USB implementation USBtiny is a software implementation of the USB low-speed protocol for the Atmel ATtiny microcontrollers. Of course, it will also work on the ATmega series. The software is written for an AVR clocked at 12 MHz. At this frequency, each bit on the USB bus takes 8 clock cycles, and [...]
This circuit uses a LM339, a quad comparator. LM339 can work on single or dual supplies, it has a open collector output that can drive 15mA, low power consumption. The circuit is an untested design but it should work. I did it as many searches were made in my webpages with these keywords. There are [...]
Build a true Webserver with only 2 chips. We did it! The used CPU (MSC1210Y4 from Texas Instruments) has 16kB Flash (up to 32kB available) and 1.2 kB RAM. Enough for a Webserver (provided you are using uC/51′s included TCP/IP stack). Add Internet-Connectivity to your Applications with only a very few lines of C-Code. Many [...]

“The library makes it possible to show on the beams of the oscilloscope over a million quantization steps of signal per second (on the Pentium III machine) – less than one micro-second is sufficient for one signal sample. This software can be used for linking to real-time controlling programs as longer delays in relay of [...]
