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 .

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.

@S32kUser The S32K3 family is a highly scalable MCU that include single-core, dual-core, and lock-step core configurations. Meanwhile, NXP provides rich eco-software. For example, NXP provides a powerful IDE: S32 Design Studio(S32DS), which can be used to configure, compiler, debug. And the RTD (Real-Time Drivers) is the software development package, it includes a lot of default example projects. Low power management is always required in auto product since it's powered by battery. K3's power management is quite different with K1. Provide a one-stop application information about S32K3xx family MCU power management features for automotive customer to accelerate their application/product time to market. Besides, the software package in this page provides additional example projects for wakeup use case. All the wakeup example projects mentioned in this page are developed based on RTD/HLD, and the configuration tool is EB tresos Studio and S32 CT. The hardware is based on S32K344 Whiteboard and S32K3X4EVB-Q172. The software is based on RTD V2.0 and S32DS3.4 About the wakeup examples package, it provides very wakeup examples. The below figures summarized the package contents: Example Projects: Application Note: Any questions, please contact me.

FOC with single shunt current measurement Article focuses on solution based Field Oriented Control (FOC) technique (typically used for 3-phase PMSM motors) with single shunt current measurement and without any position sensor (sensorless). The Encoder sensor is supported by SW option, but missing on HW kit. The single shunt current measurement is advanced technique that allows decrese the cost of Bill of Material (BOM). The available example codes covers both ANSI-C and Matlab Simulink approaches and uses RTD drivers with high-level Autosar complient API or low-level non-Autosar API. FOC integrated with FreeRTOS Article focuses on integration of motor control software (based on FOC with dual shunt current measurement) and Real Time Operating System (FreeRTOS). The available example code is based ANSI-C code and uses RTD drivers with low-level non-Autosar API. Six-step commutation control. Article focuses on solution based Six-step commutation (6-step) technique (typically used for 3-phase BLDC motors) with Hall position sensor and without any position sensor (sensorless). The available example codes covers both ANSI-C and Matlab Simulink approaches and uses RTD drivers with low-level non-Autosar API. Note: the list of use cases cannot cover all combinations of MCU, current measurement scenario, control technique and sensor inputs, but should work as a base reference for most common configurations.
