I am wondering if anyone could possibly shed some light on a problem I am having with interfacing my
AT90S2313-10PI. I have an old 8 bit 4 channel TI adc0834acn the problem I am having is after I start the conversion going send a few bits into the digital in port of the adc to select channel and such the documentation of the chip says that it takes 8 clk cycles to complete the conversion. My question is do I have to provide those clock cycles myself by taking clk high and low 8 times or is it internal and I just have to use the clk when inputting or receiving data serially? I am very new to AVR and microcontrolers this is even my first project. I may have left some important info out if so just let me know I will provide what I know. thanks everyone!
