stm32f407 adc example

Before we study stm32f4 we have to know a little about the micro-controller. Micro-controller is a small computer on a small single integrated circuit, containing a processor, memory and programmable input-output prefers. Micro-controllers are designed for embedded applications. The majority of micro-controllers are used today by embedding in other machinery .such as automobiles, computer systems,[…]

bus-fuse 12C-Circuit

All I2C cards published so far in this magazine (see References/bus-fuse) are normally powered by the 5 V supply in the PC via the 6-way DIN socket on the 12C PC insertion card. A drawback of this arrangement is that the 5 V supply in the PC is at risk of being short-circuited by a[…]

I2C Parallel printer port adaptor

The circuit in the diagram permits I2C software programs to communicate via the Centronics outputs of any IBM compatible PC in conjunction with a buffer IC Type 74LSO5. This IC has open collector outputs to facilitate the parallel switching of I2C applications on the bus. A slight drawback of the present circuit is that everything[…]

Hexadecimal display decoder

The byte to hex display decoder was designed because nibble to hex decoders are no longer produced commercially In Principle, it is, of course, not difficult to decode a nibble, but from byte to hex is generally more practical and requires fewer ICs. The decoder uses a GAL Type 22V10. This type has an adequate[…]

Solid State Voice Recorder

Integrated circuits ISD 1012, ISD 1016 and ISD 1020 from chip maker ISD enable sounds to be recorded and played back. The final two digits in type coding show the length of a sound message in seconds. The difference in recording and playback is caused by the sampling frequency. which is highest (10.6 kHz) for[…]
