ADC – LPC 2148 SFRs used are: ADC control register - ADCR ADC Data Register - ADDR These two are channel specific (i.e AD0CR, AD1CR, AD0DR, AD1DR) We use a global data register – ADGDR (AD0GDR, AD1GDR) ADC control register - ADCR % SEL bits CLKDIV is similar t...
ADC – LPC 2148 SFRs used are: ADC control register - ADCR ADC Data Register - ADDR These two are channel specific (i.e AD0CR, AD1CR, AD0DR, AD1DR) We use a global data register – ADGDR (AD0GDR, AD1GDR) ADC control register - ADCR % SEL bits CLKDIV is similar to PR of other peripherals Note: Max value of ADC clk is 4.5 MHz. Determine the corresponding PR value. So value for Clkdiv is 00001101 Burst = 1 (Repeat mode) CLKS Start Bits : 24:26 must be 001 to start the conversion
