*******************************************************************************  The purpose of this demo application is to present a usage of the  LPSPI IP Driver for the S32K3xx MCU.  The example uses LPSPI2 for transmit & receive Twelve bytes using the DMA. MOSI MISO connected on Hardware in loopback.  ------------------------------------------------------------------------------ * Test HW: S32K3X2EVB-Q172 * MCU: S32K312 * Compiler: S32DS3.5 * SDK release: RTD 3.0.0 * Debugger: PE micro * Target: internal_FLASH ******************************************************************************** DATA and Instruction CACHE is enabled by default --> in startup code :--     ========= This selection enable the use of CACHE driver API =========     ============= Use this MACRO ==================== #define USE_NON_CHACHABLE_REGION 1 This MACRO comment & uncomment will allocate the buffer in cachable & non cacable region of memory. You can allocate the SPI buffer in in cachable & non cacable region of memory. Enabling & disabling of this MACRO will adjust the example code.     ============ How this example works : Cacheable region used ============ I have connected MOSI and MISO pins of spi at hardware level. Whenever I am  sending and receiving total 10 numbers of 12 byte packet On each transmission of 12 byte packet I am incrementing the first bite of transmit buffer just to distinguish between packets at the receive side Cache_Ip_InvalidateByAddr() --> I have to call this API every time I receive 12 byte of data on receive buffer Cache_Ip_CleanByAddr() --> every time after incrementing the transmit buffer first byte ...I have to call this API then only the correct data is transmitted otherwise it will transmit the same data which was available at first time transfer ================ Cache API operation ============== Cache_Ip_InvalidateByAddr() is for the  invalidate operation. Cache_Ip_CleanByAddr() is for the clean operation or clean&invalidate operation that can be chosen by param of this api: @Param[in]  enInvalidate      Specifies to execute operation Clean&Invalidate. Clean: This operation ensures that all dirty lines—data in the cache that has been modified but not yet written back to the main memory—are written back to the main memory ->(push data from cache memory to main memory)  Invalidate: This operation marks the cache lines as invalid, ensuring that any subsequent access to these lines results in a fetch from the main memory, thus ensuring data consistency ->(push data from main memory to cache memory) Clean&invalidate : A cache clean and invalidate operation behaves as the execution of a clean operation followed immediately by an invalidate operation. Both operations are performed to the same location. ================ Pins used ======================

Abstract This example presents an use case for analogue data capturing using eMIOS, BCTU, SAR-ADC and DMA modules on S32K39-37-36 series based on the RTD low level API to support diverse application needs.   Connections: S32K396-BGA-DC1 -> Pin -> Signal -> Label J62-1 -> PTC30 -> siul2_gpio_xx -> GPIO1_GPT (D0) J58-1 -> PTE14 -> emios_0_ch_19_z -> PWM1 J58-2 -> PTG9 -> siul2_gpio_xx -> GPIO2_eMIOS_Trigger J62-2 -> PTC31 -> siul2_gpio_xx -> GPIO3_BTCU_Trigger J62-4 -> PTD6 -> siul2_gpio_xx -> GPIO4_BTCU_Watermark J62-24 -> PTB14 -> adc1_s21 -> ADC1 *To use the potentiometer of S32X-MB connect: J62-24 (in S32K396-BGA-DC1) to P26-1 (in S32X-MB) Note: Following line should be added in project/generate/src/Bctu_Ip_PBcfg.c every time the code is updated in Config Tools: #define DMA_LOGIC_CH_0 ((uint8)0U)   Detailed Description: The Compare Value of GPT eMIOS_0_ch_0 generates a time-out period. Once time-out is reached its Emios Notification toggles GPIO1. This allows us to observe in scope 2 events, which describe the start and the end of the signal sequence. The eMIOS_0_ch_23 channel is configured as global counter bus A. In this setup, it can act as the time base for other eMIOS_0 channels, enabling synchronization between other them—there is just one PWM in this case. This synchronization ensures that channels share the same time base, thereby defining a common period for their operation. The emios_0_ch_19_g channel is configured as OPWMT mode, which offer more flexibility for triggering. An interrupt is requested on every flag event, during which GPIO2 is toggled—happens at half the time high in this case. This flag event, can be configured using Trigger parameter. For more details about eMIOS, please refer to S32M27x/S32K3 – eMIOS Usage, considering differences for porting from S32K3 to S32K39-37-36 in AN14301. The BCTU implements a list for parallel conversions using ADC0 and ADC1. Which is triggered by the eMIOS channel, and the resulting data is stored in FIFO1, as follows: ADC0: VREFH_ChanNum51 -> BANDGAP_ChanNum48 ADC1: VREFL_ChanNum50 -> S21_ChanNum45 For debugging purposed the GPIO3 is toggled every BCTU Trigger Notification. Additionally, the GPIO4 is toggled in BCTU Watermark Notification, which happens every time the number of active entries in FIFO exceeds the watermark level, and therefore the data is available for reading. See full signal sequence in Figure 1: Figure 1. Signals of example project When you suspend debug session, in Expressions tab (Figure 2) you can observe results: g_fifo1Result, which corresponds to the BCTU list measurements, meanwhile g_fifo1Volts corresponds to the conversion in volts.

Once time-out is reached its eMIOS notification toggles GPIO1. This allows us to observe in scope 2 events, which describe the start and the end of the signal sequence. The eFlexPWM0 module is used for generating PWMs and hardware ADC triggering. The eFlexPWM0 Submodule 2 is employed to generate center-aligned complementary PWM outputs (PWM1 and PWM2) with dead-time insertion. The eFlexPWM0 Submodule 0 generates another independent PWM output (PWMT) and is utilized to generate the trigger signal for analog data capturing within the same PWM period —happens at half the time high in this case—using VAL0 register. The BCTU implements a list for parallel conversions using ADC0 and ADC1. Which is triggered by the eMIOS channel, and the resulting data is stored in FIFO1, as follows: • ADC0: VREFH_ChanNum51 -> BANDGAP_ChanNum48 • ADC1: VREFL_ChanNum50 -> S21_ChanNum45 For debugging purposed the GPIO3 is toggled every BCTU Trigger Notification.

******************************************************************************************************* * Detailed Description: This demo showcases how to use eMIOS in Input Capture mode with DMA. It demonstrates how timestamp data from captured input signals is stored and how a GPIO toggle provides a simple visual confirmation that the interrupt is being triggered as expected.   * eMIOS Pwm: Configures EMIOS 0 Channel 1 as OPWMB (Output Pulse Width Modulation Buffered). This channel generates a waveform that will be captured by Channel 9 * eMIOS Icu with DMA: Configures EMIOS 0 Channel 9 in ICU_MODE_TIMESTAMP using SAIC (Single Action Input Capture) mode. This channel captures the timestamps of the waveform generated by Channel 1.

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 post is an additional project to the S32K3 Low Power Management AN and demos.  A simple FlexCAN routine is configured for RX/TX and wakeup through the CAN0_RX pin (PTA6/WKPU19). The example is based on the S32K3X4EVB-T172, meaning that transceiver TJA1443 is used. TJA1443 only needs CAN0_EN & CAN0_STB pins in HIGH for normal configuration. In the example, the GREEN led is used to indicate that the MCU is in RUN mode. Once SW5 is pressed, MCU enters low power (STANDBY), and led is turned off. BLUE led toggles each time a CAN frame is received. MCU can be woken up with SW6 (WKPU42) or through a CAN RX. Note that CAN is not enabled in low-power, rather PTA6 (WKPU19) is configured for wake up, and once a rising edge signal is detected on the pin, MCU wakes up and reconfigures CAN module.  ------------------------------------------------------------------------------ * Test HW: S32K3X4EVB-T172 * MCU: S32K344 * Compiler: S32DS3.6.2 * SDK release: RTD 6.0.0 * Debugger: PE Micro * Target: internal_FLASH  ------------------------------------------------------------------------------ This example is provided as is with no guarantees and no support.

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:
