GPIO Output (LED1, LED2, LED3, LED4) and
GPIO Input (Switch1, Switch2, Switch3) on TRK-MPC5606B board are used to test GPIOs.
In this program,
Switch 1 Pressed -> LED1 ON otherwise OFF Switch 2 Pressed -> LED2 ON otherwise OFF Switch 3 Pressed -> LED3 ON otherwise OFF LED4 is continuouslt toggling (Blinking)
Delay is generated using "for" loop only which is not the recommended way. (Delay in this program is not accurate delay.)
Problem Statement:To Test the GPIOs of the TRK-MPC5606B board using LEDs and Switches.
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 SWITCH No. => Port No. => Pad No. => Pin No.(144-pin LQFP package)SWITCH1 => PE[0] => PCR[64] => PIN 10 SWITCH2 => PE[1] => PCR[65] => PIN 12 SWITCH3 => PE[2] => PCR[66] => PIN 128 SWITCH4 => PE[3] => PCR[67] => PIN 129
To change the time for which LED4 should be ON and OFF, Change the constant value from if condition
