******************************************************************************************** * Test HW: S32K312 EVB-Q172 * MCU: S32K312 * Compiler: S32DS3.5 * SDK release: RTD 3.0.0 * Debugger: PE Micro * Target: Internal_FLASH ******************************************************************************************** The objective of this demo application is to generate an interrupt by comparing DAC internal reference voltage against any analog input which is connected in analog mux input channels(IN0 : IN7) and wakes the MCU from sleep(standby) mode. In this demo code, 1)LPCMP0 is used - DAC output is given to comparator minus (INM) and AIN2 is given to comparator plus (INP). From S32K3 RM, highlighted the channels used for reference. Green color represents DAC, Pink color represents AIN2 which is selected from PMUX 2) From S32K RM, "Compares two analog input voltages applied to INP and INM, COUT_RAW is high when the INP input voltage is greater than the INM input voltage, COUT_RAW is low when the INP input voltage is less than the INM input voltage" So in this demo code, RED LED is ON , if AIN2 Voltage > DAC Internal reference voltage(COUT is HIGH) GREEN LED is ON, If AIN2 Voltage < DAC Internal reference voltage (COUT is LOW) MODULES USED: MODIFICATIONS IN LPCMP MODULE: MODIFICATIONS IN INTCTRL_IP MODULE: MODIFICATIONS IN WKPU MODULE: From S32K3 RM, Analog comparator has used Channel 2 for wakeup. Modifications in the "Cmp_Ip_IrqHandler" function in "Cmp_IP.c" source file: NOTE: Not sure how it got missed or from where to get COUT status, so added manually to get COUT status from CSR register in the Cmp_Ip_Irqhandler once code generation is completed. PIN SELECTION DETAILS: HOW TO TEST? a) Connect jumper wire at the PTC2 in the EVB as highlighted in EVB below. b) RED LED ON -> Jumper wire connects to 5V GREEN LED ON-> Jumper wire connects to GND c) MCU enters STANDBY once SW5 is pressed and it wakes up if the jumper wire is disconnected from either 5V or GND. NOTE: In this demo, since jumper wire is used instead of button/ADC, due to high impendence state, LED will be toggling if jumper wire is not connected to GND/5V. Connect male jumper wire at PTC2 Thanks & regards, Krishnakumar V

This is an example project which is created to do an internal wake up from VLPS mode using LPTMR0. From S32KRM, it tells us that internal wakeup is achievable using LPTMR0. What code does? ======================================= 1) LPTMR0 is configured for 5 Seconds. So for interrupt occurs for every 5 seconds 2)LPTMR0 wakes up MCU for every 5 seconds and again it goes back to sleep for next 5 seconds. This cycle repeats forever. 3) When MCU is in RUN mode, GREEN color LED will be ON and it will in OFF if it goes to VLPS. Project Configurations: ======================================= Other Informations: ======================================= Design studio: S32DS3.4 SDK : RTM 4.0.2 EVB : S32K118EVB2Q048 Note: Following symbols should be included if you are creating the project from scratch to properly put MCU to sleep and wakeup from POR. Thanks & regards, Krishnakumar V

Hi team, First let me explain about the code about what it does. ======================================= 1) From POR, LED starts blinking - In this state RTC won't be initialized. 2) Once SW5 is pressed in S32K312 EVB - RTC will be initialized before MCU goes to sleep. 3) RTCCNT will be incrementing during sleep 4) Once SW6 is pressed , MCU wakes from the sleep and we could able see the updated RTC time and date. WAR(Work Around)done to keep RTC alive during sleep: ======================================= Tried to test the RTC with sleep mode, observed that RTCCNT value is getting reset once after every wakeup. So that time and date was not able to preserve the value. In order to avoid this, I have done two workarounds to solve this RTCCNT value reset issue. 1) RTC will not be initialized for if MCU wakeup from the sleep - Made the check to initialize when MCU is not from the wakeup before it goes to sleep. wake_up_event will be incremented if MCU reset reason is wakeup as shown below. 2) Updating "Rtc_Ip_u32ChState" array variable for "ticksPerSecond" member in "Rtc_Ip.c" file manually after the code generation is completed. Note: With auto generated code the value of "ticksPerSecond "will be "0". Any other alternatives other than this approach is highly appreciated. Thanks in advance!
