How do I generate ramp output from the DAC0808 interfaced to 8051?
I'm more familiar with SPI. Can you guide me on how to use it for this purpose?
Of course. You need to send a sequence of bits to the DAC0808 to generate the ramp output. The first byte should be the command byte, which sets up the DAC0808 for operation. The second and third bytes should be the data bits that determine the ramp output. Do you need help with the actual code?
