/******************************************************************************** Detailed Description: Example shows possible implementation of multiple ADC conversions using SDK. Here 7 channels are sampled periodically. 2 ADC modules and 2 PDBs are used. ADC0 is configured to sample 3 channels, ADC1 4 channels. PDBs are set to back-to-back mode to perform chain conversion as shown in RM's Figure 46-3. PDB back-to-back chain forming PDB0-PDB1 ring. Within ADC component you need to select ADC input to be measured for each item in configuration list. For ADC0 ch5 External input channel 28 is selected, as it is connected to potentiometer on the EVB. PDB0 is triggered by LPIT ch0 at 500ms rate. * ------------------------------------------------------------------------------ * Test HW: S32K148EVB-Q144 * MCU: FS32K144UAVLQ 0N20V * Target: Debug_FLASH * EVB connection: UART terminal 115200, 8N1 * Compiler: S32DS.ARM.3.4 * SDK release: S32SDK_S32K1XX_RTM_4.0.3 * Debugger: S32DS ******************************************************************************** Revision History: Ver Date Author Description of Changes 1.0 Jan-26-2023 Petr Stancik Initial version, based on adc_hwtrigger_s32k148 *******************************************************************************/

Question As we know, the TPPSDK supports S32K144 MCU and various Kinetis MCUs to initialize GD3000 in NXP MC solutions. Because of the release of S32K3 and related SW RTD, it’s necessary to expand the capability of TPPSDK to support S32K3 MC based RTD LLD driver or MCAL driver. Unfortunately, the AA team will not maintain the TPPSDK anymore. How could we configure the GD3000 chip for S32K3 platform? Answer I took some time to finish this work. Here I'd like to share you the The Expanded TPPSDK Based on S32K3 RTD that is suitable for S32K3 MC application. You can find the Application Note, the source code of new TPPSDK (GD3000 driver), two examples in the attachment. I hope these materials can help you get start with the expanded TPPSDK on S32K3.

******************************************************************************************************* * Detailed Description: The purpose of this demo application is to present some usage modes of the eMIOS for the S32K3xx MCU. The application uses the eMios_Pwm driver as OPWMCB ( Center aligned Output PWM Buffered with dead time), OPWMB (Output Pulse Width Modulation Buffered) and OPWMT (Output Pulse Width Modulation Trigger) to generate waveforms. PWM signal generated by EMIOS 0 CH 1 (OPWMCB mode), EMIOS 0 CH 2 (OPWMCB mode), EMIOS 0 CH 3 (OPWMB mode) and EMIOS 0 CH 4 (OPWMT mode). Each waveform was manipulated to demonstrate a capability (dead time insertion and phase shift) of the configured mode. The application also uses the eMios_Icu driver as ICU_MODE_SIGNAL_MEASUREMENT in SAIC (Single Action Input Capture) mode with interrupts and IPWM (Input Pulse Width Measurement) mode without interrupts to obtain the duty cycle of the captured signal. PWM signal generated by EMIOS 2 CH 8 (OPWMB mode) measured by EMIOS 1 CH 5 (SAIC mode) AND CH 6 (IPWM mode). * Test HW: S32K3X4EVB-T172 * MCU: S32K344 * Debugger: S32DS 3.5, OpenSDA * Target: internal_FLASH *******************************************************************************************************

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. Since Rev. B2 of S32K3X4EVB-T172 was used to test the project, TJA1043 transceiver is mounted on the board and used to test the examples. ------------------------------------------------------------------------------ * 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 (LLD) 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 INTERRUPT. If TJA1153 transceiver is used, macro TJA1153 must be uncommented at the top of the project, and it will be initialized through a custom configuration sequence. If not used and the macro is commented, normal transceiver initialization is done (only CAN0_EN_PIN & CAN0_STB_PIN set to HIGH). Rx Filter mask type is individual and set to receive STD ID 123h. Tx MB is set to STD ID 001h. FlexCAN bitrate was calculated with MPC5xxx/S32Kxx/LPCxxxx: CAN / CAN FD bit timing calculation. FlexCAN bitrate settings are 500kbps with 81.25% sample point FPE_CLK: 24MHz Synch seg: 1 Prop seg: 4 Phase 1 seg: 8 Phase 2 seg: 3 Prescaler: 3 RJW: 3 Example 2: FlexCAN MCAL Layer (HLD) This project configures both Can_43_FLEXCAN and CanIf modules for CAN communication. Transmission is done via POLLING, while reception is configured via INTERRUPT. Tx MB is set to STD ID 123h. Acceptance mask is set to 0x0 (accept all IDs). CAN messages are sent using Can_43_FLEXCAN_Write() and received using the CanIf_RxIndication() callback. After CanIf_bRxFlag is set, an ACK message is sent back. The GREEN LED toggles every 10 received messages. FlexCAN bitrate was calculated with MPC5xxx/S32Kxx/LPCxxxx: CAN / CAN FD bit timing calculation. FlexCAN bitrate settings are 500kbps with 81.25% sample point FPE_CLK: 24MHz Synch seg: 1 Prop seg: 4 Phase 1 seg: 8 Phase 2 seg: 3 Prescaler: 3 RJW: 3 If TJA1153 transceiver is used, macro TJA1153_EVB_TRCV must be used. If not, use TJA1043_EVB_TRCV for standard transceiver initialization (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.

Customer may need more high performance via S32K3xx. How to optimization user's code? As following have some suggestions: 1. Most of user code allocate to P-Flash and enable I-Cache 2. Allocate system stack to D-TCM and enable D-Cache 3. Execute code frequently allocate to I-TCM. E.g., ISRs etc. 4. OS' task stack allocate to D-TCM 5. vector table allocate to D-TCM Please note: 1. Due to enable D-Cache, other masters(E.g., DMA, HSE, another APP cores) access theses area of cacheable will be impact. So, theses area need to allocate to non-cacheable area. 2. If another master(E.g., DMA, HSE and another APP cores) access the D-TCM need to over back door. E.g., core1/DMA/HSE access core0' DTCM needed to over backdoor. Information: S32K3' Coremark in RM, theses Coremark' value are from ARM. If used IAR/GHS etc and set compiler flag, then the Coremark value is very closely with RM. If used GCC, then the Coremark value will less than RM. BR Tomlin
