按照之前的计划，S32K144采集相关数据后，打包到CAN报文，然后发送到总线上。
接收方目前暂定使用恩智浦公司的MCXN947搭配一块官方屏幕。屏幕上的GUI设计也采用恩智浦推出的Gui Guider来快速设计并生成基于FreeRTOS的Keil工程。
本次的过程贴主旨是记录接收方的相关设计。
GUI Guider是恩智浦提供的用户友好型图形用户界面开发工具，可通过开源LVGL图形库快速开发高品质的显示。GUI Guider的拖放编辑器可以轻松利用LVGL的众多特性，如小部件、动画和样式来创建GUI，而只需少量代码或根本无需任何代码。
单击按钮，您可以在模拟环境中运行应用或将其导出到目标项目。可以很轻松地将GUI Guider生成的代码添加到MCUXpresso IDE或IAR Embedded Workbench项目中，从而加速开发过程，并允许无缝地将嵌入式用户界面添加到应用中。
GUI Guider可免费与恩智浦的通用和跨界MCU一起使用，并包括用于多个受支持平台的内置项目模板。
详细的下载安装包可以参考：https://www.nxp.com.cn/design/design-center/software/development-software/gui-guider:GUI-GUIDER
gui设计好后，还可以点击Simulator来查看效果：
之后点击生成代码：
打开生成的keil工程，添加fsl_flexcan.c驱动
配置CAN收发引脚：
/*

const port_pin_config_t port1_10_pinC3_config = {/* Internal pull-up/down resistor is disabled */
kPORT_PullDisable,

/* PORT1_10 (pin C3) is configured as CAN0_TXD */
PORT_SetPinConfig(PORT1, 10U, &port1_10_pinC3_config);
/*

/* Pin Control Register fields [15:0] are not locked */
kPORT_UnlockRegister};
/* PORT1_11 (pin D3) is configured as CAN0_RXD */
PORT_SetPinConfig(PORT1, 11U, &port1_11_pinD3_config); 设置Rx过滤器，接收id为0x555的报文
/* Setup Rx Message Buffer. */ mbConfig.format = kFLEXCAN_FrameFormatStandard; mbConfig.type = kFLEXCAN_FrameTypeData; mbConfig.id = FLEXCAN_ID_STD(0x555); #if (defined(USE_CANFD) && USE_CANFD) FLEXCAN_SetFDRxMbConfig(EXAMPLE_CAN, RX_MESSAGE_BUFFER_NUM, &mbConfig, true); #else FLEXCAN_SetRxMbConfig(EXAMPLE_CAN, RX_MESSAGE_BUFFER_NUM, &mbConfig, true); #endif
接收成功后，把两组数据分别存储到全局变量中
if(rxComplete){
rxComplete = false;
PRINTF("\r\n CAN Rx Done\r\n");
PRINTF("\r\nReceived message from MB%d\r\n", RX_MESSAGE_BUFFER_NUM);
//PRINTF("EXAMPLE_CAN_CLK_FREQ = %u MHz, CAN BUS bitRate = %uk bps\r\n", EXAMPLE_CAN_CLK_FREQ/1000000, (flexcanConfig.bitRate)/1000);
PRINTF("rx frame CanID = 0x%x\r\n", (rxFrame.id)>>18);
PRINTF("rx word0 = 0x%x, 0d%d\r\n", rxFrame.dataWord0, rxFrame.dataWord0);
PRINTF("rx word1 = 0x%x\r\n", rxFrame.dataWord1);
tempVal1 = rxFrame.dataWord0;
tempVal2 = rxFrame.dataWord1;
PRINTF("\r\n POT: %d mV",tempVal1);
PRINTF("\r\n Vref: %d mV",tempVal2);
(void)FLEXCAN_TransferReceiveNonBlocking(EXAMPLE_CAN, &flexcanHandle, &rxXfer);
}验证：在USB-CAN调试工具中增加id为0x555的报文，可以看到MCXN947 （COM57）接收到了报文
