ADC stands for Analog to Digital Converter.
ADC1 on TRK-MPC5606B is a 12-bit ADC.
ADC1_ScanMoode example for MPC5606B (Tested on TRK-MPC5606B Board)
Description:
Converts inputs ANP0, ANP1 and ANP2 of (ADC1 - 12bit - 0 to 4096) using scan mode (continuous).
Reading Analog input (0 to 5V) using ANP0 and Its output is shown using 4 LEDs as below.
Program Outcome:
Analog INPUT => OUTPUT (PB[4]) [LED1 LED2 LED3 LED4] DigitalOutcomeValue (0-1000) => ON OFF OFF OFF DigitalOutcomeValue (1001-2000) => ON ON OFF OFF DigitalOutcomeValue (2001-3000) => ON ON ON OFF DigitalOutcomeValue (4001-5000) => ON ON ON ON
Problem Statement:Reading Analog input (0 to 5V) using ANP0 and Its output is shown using 4 LEDs as below.
Connections:
LED No. => Port No. => Pad No. => Pin No.(144-pin LQFP package) LED1 => PE[4] => PCR[68] => PIN 132 LED2 => PE[5] => PCR[69] => PIN 133 LED3 => PE[6] => PCR[70] => PIN 139 LED4 => PE[7] => PCR[71] => PIN 140 SIGNAL ADC1_Channel PORT SIU_PAD_CONFIG PACKAGE_PIN (100 144 176) ANP0 => CH0 B4 PCR[20]=2000 50 72 88 ANP1 => CH1 B5 PCR[21]=2000 53 73 91 ANP2 => CH2 B6 PCR[22]=2000 54 76 92 Connect Jumper J19 and J20 in (2-3) Position to provide Supply to ADC1 module
NOTE:1. Do not forget to add "ME.PCTL[68].R = 0x01;" line in void initModesAndClock(void) function to make ADC1 work.
2. On TRK-MPC5606B Board, Connect Jumper J19 and J20 in (2-3) Position to provide Supply to ADC1 module
