#48173 - RE: adc0808, dac0808 with 8051 Responding to: ???'s previous message |
i'm trying to reconigize a type of wave form. i have use Matlab for the program. the problem i am having now is working with ADC0808. I assembled the ADC with a clock of 10kHz at 51% duty cycle. ALE and START are tied together. one variable DC input is being sampled 0-5V. Vcc and Vref is 5V. the output is display by 8 LEDs. The conversion starts by my left index finger with a push button that is debounced. After the conversion, the LEDs are all on or off. Would you help me in constructing the ADC?
ABC = 111 for multiplex input #7 Vcc=5V Vref=5V (should this be 2.5V?) CLK=10kHz at 51% duty cycle START+ALE=0 -> 5V to start please help... and thank you for responding so soon |
