you have to check the duty cycle here also. at the time of low it'll counts or converts. so plz try to make the convert signal more low in duty cycle.
Here is the ckt that i tried on multisim.....Also here i have provided an i/p 00011111 manually instead of using adc0808
This provides the Binary to BCD conversion. Use BCD to 7-seg decoders like 4543, or 4511 for the displays.
well, i wish you could understand what i'm trying to explain, i'm ecuadorian so i don't know if it's well written jajajajaj. In my project i need to convert the binary signal of 8 bits to BCD of 2 digits so i don't know if i only have to remove U5 4510 and the output TC of U2 looks like U5. if i do that what problem could i have???
yes, i want to convert only binary values from 0 to 99.I believe I understand what you are getting at. You can remove the 100's digit by removing U5 and all the connections to it, but then, of course, you can convert only binary values from 0 to 99. In other words, after doing so, you can't convert the entire range of values an 8-bit binary number can represent.
I have done this many times by simply programming an EPROM to convert into two x four bits.
