#112547 - ADC / DAC with ADuC832 |
Hello!
I joined a few weeks ago and found already some interesting things to use! Now I'm doing a project with the microconverter developmentboard of Analog Devices ADuC832. At first I'm trying all the possibilities of the pins as I/O's, ADC/DAC, PWM, T/C's,.. Now I'm having some troubles with the ADC. On the board there is a LDR at ADC.3 and i want this value to be displayed on P3 (where there is a LEDbar attached). Véry simple, but the output stays with one value only. Mayby my little program could be some more help with my explenation : $MOD832 ; use 8082 predefined symbols CSEG ; defines the following as a code ORG 1000h INIT: ANL ADCCON1,#11001000B ;ext ref / f/8 / 3acq ANL ADCCON2,#00100011B ;cont mod / CH3 OUT: MOV P3,ADCDATAL ;ADC value to P3 WAIT: MOV A,ADCCON3 JB ACC.7,WAIT ;wait for busy flag to be 0 SJMP OUT ;display again END OK I see the code is not as nice displayed but it's very small :-). thx in advance!! ps : mayby a good exercise for the tutorials :-) Best Regards, LJ |
