What is S32K1‘s IDLE feature: IDLE is set when the LPUART receive line becomes idle for a full character time after a period of activity.When CTRL[ILT] is cleared, the receiver starts counting idle bit times after the start bit. Why write this demo? Because the RTM driver does not support Lpuart's IDLE detect. What needs to be modified? -1.add "UART_EVENT_DMA_IDLE = 0x04U" to “callbacks.h”   -2 add "LPUART_DRV_RxIdleCallback" to ".lpuart_driver.c"   -3 Define “LPUART_DRV_RxIdleCallback” function   static void LPUART_DRV_RxIdleCallback(uint32_t instance) { DEV_ASSERT(instance < LPUART_INSTANCE_COUNT); LPUART_Type *base = s_lpuartBase[instance]; lpuart_state_t * lpuartState = (lpuart_state_t *)s_lpuartStatePtr[instance]; LPUART_ClearStatusFlag(base,LPUART_IDLE_LINE_DETECT); if(lpuartState->transferType == LPUART_USING_DMA) { lpuartState->rxSize = EDMA_DRV_GetRemainingMajorIterationsCount(lpuartState->rxDMAChannel); LPUART_DRV_StopRxDma(instance); lpuartState->rxCallback(lpuartState,UART_EVENT_DMA_IDLE,NULL);/*UART_EVENT_DMA_IDLE : 0x04*/ } }     -4 add below code to "LPUART_DRV_IRQHandler" and be sure these code must  be put before "LPUART_DRV_ErrIrqHandler(instance)" /* Handle idle line interrupt */ if (LPUART_GetIntMode(base, LPUART_INT_IDLE_LINE)) { if (LPUART_GetStatusFlag(base, LPUART_IDLE_LINE_DETECT)) { LPUART_DRV_RxIdleCallback(instance); } }   -5 configure IDLE releated register in main function. LPUART1->CTRL |= LPUART_CTRL_ILT(1); LPUART1->CTRL |= LPUART_CTRL_IDLECFG(7); LPUART1->CTRL |= LPUART_CTRL_ILIE(1);   Test environment: Hardware is base on S32K144EVB-Q100 Software is S32 Design Studio for Arm V 2.2 + RTM 3.0.X Demo Description:           The baud rate of the serial port is set to 19200, and the function implemented is to send back the received data using DMA methods .

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

This post presents two complementary FlexCAN communication examples for the S32K3X4EVB-T172 evaluation board, showcasing both low-level IP layer and AUTOSAR MCAL layer implementations. These examples are basic routines for configuring the component in normal/user mode, as the RTD examples are configured for loopback mode. To test CAN communication, another board or a CAN analyzer must be used. ------------------------------------------------------------------------------ * Test HW: S32K3X4EVB-T172 * MCU: S32K344 * Compiler: S32DS 3.6.2 * SDK release: RTD 6.0.0 * Debugger: PE Micro * Target: internal_FLASH ------------------------------------------------------------------------------  Example 1: FlexCAN IP Layer This project demonstrates a basic FlexCAN setup using the IP-level driver. It configures a standard CAN message; with transmission through polling and reception using interrupts. The TJA1153 transceiver is initialized through a custom configuration sequence. An ACK message is sent upon each reception. The GREEN LED toggles every 10 received messages. Message buffer is configured to accept STD ID 0x123 with  FlexCAN_Ip_SetRxIndividualMask()  &  FlexCAN_Ip_ConfigRxMb() .  Example 2: FlexCAN MCAL Layer This project uses the AUTOSAR MCAL stack, leveraging  Can_43_FLEXCAN  and  CanIf  modules for CAN communication. Transmission is done via polling, while reception is configured via interrupts. STD ID is set to 0x123, and acceptance mask is set to 0x0 (accept all IDs). The same TJA1153 transceiver is used. CAN messages are sent and received using  CanIf  callbacks. The GREEN LED toggles every 10 received messages. TJA1153 is used in both examples with macros TJA1153 & TJA1153_EVB_TRCV respectively. If not defined, standard transceiver initialization is done (CAN0_STB & CAN0_EN pins set to HIGH).  These examples are provided as is with no guarantees and no support. These are basic routines meant to be used as reference only.

This simple example demonstrates how to configure and handle UART interrupts using the LPUART module on the S32K312-EVB. It sets up a UART callback function and initiates reception in single-byte mode. After each byte is received, the buffer is updated using  Lpuart_Uart_Ip_SetRxBuffer() , unless a newline character ( '\n' ) is detected, in which case a reception flag is set to signal the main loop. When the  LPUART_UART_IP_EVENT_END_TRANSFER  event occurs, reception is re-enabled using  Lpuart_Uart_Ip_AsyncReceive() . Only basic event handling is implemented; other UART events are acknowledged but not processed. The example uses LPUART instance 6, enabling serial communication via the USB port (J40) on the S32K312-EVB. If using TeraTerm, ensure the transmit setting is configured to LF (Line Feed) to properly send newline characters when pressing Enter.  ------------------------------------------------------------------------------ * Test HW: S32K312EVB-Q172 * MCU: S32K312 * IDE: S32DS3.6.2 * RTD release: 6.0.0 * Debugger: PE Micro * Target: internal_FLASH  ------------------------------------------------------------------------------ Test result:

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!

The following article is intended to give an example on the use of the FS26 in standby mode with the S32K3 MCU also in standby to get lower consumptions on costumer designs and waking up both through an external wake (EXTWAKE) and the PGOOD SBC signal. Software requirements: The attached codes uses the following SW requirements: S32K3 RTD 4.0.0 HF02 FS26 SBC RTD 3.0.0 HW Requirements: There are a few reworks needed on the EVB in order to make the code work.  S32K3X8EVB-Q289 Rev B2: 1.- Remove resistor R2301 and place R2304 instead, this change is because the PTA8 signal has the EXTWAKE option on the user push-button, this allows that when you send a WKPU request from the MCU (with the push-button) what the MCU does when it has PGOOD activated is that it sends an EXTWAKE signal to WAKE1 of the FS26.     2.- Change the J685 jumper position to 2-3, this jumper is the VDEBUG mode.       3*.- Optional: FS26 DS recommend FCCU lines with certain values of resistors on their lines that are not present by default on the S32K3X8EVB-Q289.          I've attached the example program on a ZIP file, hope it helps.
