******************************************************************************** Detailed Description: Configures the FlexCAN 0 to transmit and receive a CAN message Baudrate to is set to 500kbps. In this config, RXFIFO is used to receive a messages. 16 filter elements are defined in the RXFIFO table. Both standard and extended IDs are used. DMA is enabled in component inspector to read RXFIFO. MB10 is moreover used to receive a message with given standard ID and MB11 is used to transmit a message upon button press. The callback function is installed as well and is it called each time message is received in MB10, RXFIFO or message is transmitted.

/******************************************************************************** Detailed Description: Example shows possible implementation of multiple ADC conversions using SDK. Here 25 channels are sampled periodically. 2 ADC modules and 2 PDBs are used. ADC0 is configured to sample 16 channels, ADC1 9 channels. PDBs are set to back-to-back mode to perform chain conversion. Within ADC component you need to select ADC input to be measured for each item in configuration list. For ADC0 channels ADC ch12 is selected, as it is connected to trimmer on the EVB. DMA is used to read result into single buffer, and DMA callbacks are issued to indicate end of transfer for each ADC module. Within those callbacks PTE14 and PTE15 is toggled. PDB0 output pulse is generated on the PTE16 to indicate start of ADC measurement. This is done periodically at LPIT ch0 rate, which is set to 30us. The ADC0 ch0 result is used to dim LEDs. * ------------------------------------------------------------------------------ * Test HW: S32K144EVB-Q100 * MCU: FS32K144UAVLL 0N57U * Target: Debug_FLASH * EVB connection: * Compiler: S32DS.ARM.2018.R1 * SDK release: S32SDK_S32K1xx_RTM_3.0.0 * Debugger: Lauterbach Trace32 ******************************************************************************** Revision History: Ver Date Author Description of Changes 0.1 May-04-2019 Petr Stancik Initial version *******************************************************************************/

Hello, NXP does a big change on document structure. Generally, you can find pin assignment table, interrupt mapping and memory map table in RM. But now, these information change to Excel files and attached in RM. For example on S32K. You will find the words in RM, like 'For reset values per port, see IO Signal Description Input Multiplexing sheet(s) attached to the Reference Manual.' Then, please go to attachment tab of your PDF file viewer, like Adobe Acrobat Reader DC. These steps are also fit for MPC57xx , S32R family. Cheers! Oliver

******************************************************************************** Detailed Description: Example shows how to use FlexCAN 0 Pretended networking mode to allow FlexCAN module to wake up MCU from STOP mode using SDK. Wake up by Timeout and wake up by Match events are enabled. Also pin interrupt can be used to exit STOP mode. So MCU enters STOP mode by pressing SW3 button. MCU exits STOP mode when one of following happens: - no CAN message comes in 8sec (CAN PN timeout event) - message with standard ID 0x554 or 0x555 comes (CAN PN match event) - SW2 button is pressed (PTC12 interrupt) In run mode blue LED is dimming and the rate is different for each wakeup event ------------------------------------------------------------------------------ Test HW: S32K116EVB-Q48 MCU: PS32K116LAM 0N96V Compiler: S32DS.ARM.2.2 SDK release: S32SDK_S32K1xx_RTM_3.0.0 Debugger: Lauterbach, OpenSDA Target: internal_FLASH ********************************************************************************

To accelerate S32K demand creation and support urgent evaluation requriement in Great China, we build one batch boards locally. These boards will only be given out to our potential opportunities for free. The boards are made by China local partner and verified by AE and FAE team. if you have any question on this kind of board, please go to China Auto CAS or Auto MCU marketing for support. 1. Board overview 2. Pinout 3. Test point 4. Block diagram 3. The main difference between NXP official S32K EVB and this FRDM-S32K144 board are OpenSDA firmware and CAN PHY The original OpenSDA firmware in this board is from MBED which is not supported by S32DS, thus we need to change to PEmicro OpenSDA firmware, and then we can use S32DS for development. Unplug the USB cable (if attached). Press and hold the Reset button. Plug in a USB cable from a USB Host to the OpenSDA USB port. Release the RESET/Bootloader button. A removable drive will be visible in the host file system with a volume label of BOOTLOADER. Drag/drop or copy/paste attached firmware “DEBUG-FRDM-K64F_Pemicro_v108a_for_OpenSDA_v2.0.bin” into the removable drive. Unplug the USB cable and plug it in again. The OpenSDA application should now be running. The CAN physical is different. This board used standalone CAN PHY but not CAN SBC. Please refer SCH file for debug.
