I had used ADC0831 (8 bit, serial) and ADC0804 (8 bit parallel) chips.
I used ADC0831 and plugged it to a pc paralell port and it worked. Then I used ADC0804 and inserted it to a ISA slot, and it worked.
Now, I want to interface any of them (I have some experience using PIC16f84) to a RS232 on a IBM-Laptop, as well to a Machintosh RS422 port.
(I made a cable to communicate a RS232 to a RS422).
Check my site www.geocities.com/the_beijing_dragon.

 

i did something similar a few days back.
I used a 89c51 to generate the cs and clock for the 0831. The clock was running at freq of 19.2khz. the CS was low for 10 clock cycles. the high and then low again for 10 clock cycles.
The DO pin of the 0831 is connected to a max232 chip and then its output is shoved into the serial port.A small code is written to read data from the serial port

 

I am looking for a simple circuit to connect ADC to USB port. Any ideas?

 

I am looking for the same solution. Please contact me if you have any idea how to do it.

hi,

currently i'm doing a project which require to connect 2 load cell to 1 ADC then to a RS232 port of a pc. pls kindly guide me on the circuit design.

thank you
