8051 based input output card

As easy as it can gets, wen connected to the serial port of your PC (RS232 port) and supplied with 5 volts current, you can send commands to the serial port in order to read or write 3 times 8 bits I/O ports plus one 6 bits I/O port, in a total of 30 I/O .

If you now a few things of electronics you can easily develop and built a circuit to get the input and outputs to serve your porpoise.

I hope to develop a board built to do that soon.

 

8051 development kit

Built in a way that resembles the PC's arquitecture is composed of three boards:

  1. The 8051 input/output cart, witch contains de micro-controller.
  2. A five-slot motherboard, one slot supports the micro-controller board, and other four for expansion boards.
  3. An expansion board with a 32K RAM and 32K ROM, capable of emulating 16K of ROM within the 32K RAM for program runtesting.

Characteristics:

  • Capability of addressing up to 4 times 64K of data RAM or other devices.
  • Capability of loading a program to the serial port and running it in a few seconds.
  • One 8 bits parallel port.
  • Available on every slot, 16 bits of address 8 bits of data two interrupts, two voltage levels 5V and 12V, RD and WR signals and PSEN.
  • The micro-controller can address separately hitch slot with no need for any additional logic.

Note: An input/output expansion board is being tested, will be available soon.

  

Intelligent RF data transceiver

If you want to send serial data from one PC to other or to micro-controller and you need a wireless connection this is just what you have been looking for.

If you need to control a wireless device from your PC this is the perfect solution, simple and cheap.

Characteristics and applications:

  1. Wireless aft-duplex point to point serial data connection.
  2. Wireless serial port networking up to 256 stations.
  3. Six input/outputs for itch device, with no additional hardware.
  4. Programmable address, intelligent error detection and 100% RF silences on no transmission.
  5. Capable of sending and receiving data, indoors up to 40 meters, furthers in open field.
