功能需求 RT117X 系列 MCU 在汽车和工业类产品中有广泛应用,有很多客户对 LIN 通讯有需求, RT1176 有 12 路独立的 LPUART 接口,最大支持的波特率能支持到 20M ,而且每一路都支持 Break 发送和中断接收,可以用来配合定时器实现 LIN 的主机和从机通讯。但是目前 RT117X 的 EVK 板没有放置 LIN 的收发器, SDK 也没有相关 LIN 的示例代码和 LIN 协议栈支持,所以本示例目的是移植 KW36 工程中的 LIN 2.1 版本的代码到 RT1176 EVK 板子上,在硬件上通过跳线将 LIN Master 主节点和 Slave 从节点的 LPUART TX/RX 线连接到 FRDM-KW36 板载的 LIN 收发器 TJA1027 上,分别实现 LIN 2.1 版本协议栈在 Master 和 Slave 节点的通讯功能验证,同时还需支持 Auto Baud Rate 自动波特率调整。为客户做二次开发或者移植用户自己的 LINstack 提供底层驱动,提高开发效率。 代码包软件   RT1176 LIN Master 节点代码: RT1170_LIN_Porting_Demo_Master.7z RT1176 LIN Slave 节点代码 ( 支持自动波特率 😞 RT1170_LIN_Porting_Demo_Slave_with_Auto_Baud_Rate.7z 配置 FRDM-KW36 板载 LIN 收发器的代码 : KW36_LIN_PHY_Board_Init.7z 硬件 Setup   MIMXRT1170-EVK : 2pcs ,分别用作 LIN Master 节点和 Slave 节点。 FRDM-KW36 : 2pcs , 分别用作 Master 节点的收发器,和 Slave 节点的收发器 下图是系统连接,2块RT1170 EVK板分别和2块FRDM-KW36板通过Arduino接口连接在一起,然后将两块KW36之间的LIN收发器通过 J13 连接在一起,需要使用外部12V adapter为FRDM-KW36供电,否则板上的LIN收发器无法工作。特别强调的是,如果需要使能自动波特率检测的话,还需要将Slave节点RT1176 Arduino接口的J9-Pin2引脚连接到RT1176 Arduino接口的J9-Pin12引脚,作为Timer 脉冲捕捉的输入,即可完成系统硬件的setup。   软件Setup:   在以上硬件连接完成后,按照如下步骤下载对应软件: - Step1: 下载KW36_LIN_PHY_Board_Init.7z代码到两块FRDM-KW36板子上;  该代码中主要实现两个功能:第1个拉高板子的PTC5引脚,唤醒LIN收发器TJA1027。第2个将PTA18引脚配置成disable高阻状态。如果该引脚作为GPIO输出或者LPUART TX功能,会导致LIN slave回应数据出错(bit位丢失或者错误)。究其原因猜测应该是短路导致,当这个引脚作为GPIO输出或者LPUART TX功能,内部会有上拉,当RX1176 TX引脚输出Low时,由于电路上没有串联电阻(板子上使用的0Ω),会导致引脚上出现大电流。尤其是第2个点,花费了很多时间去查这个问题,从波形去看,是有数据输出的,但只是数据不对,很具有迷惑性。当然如果客户是自己打的板子,板子上已经有LIN收发器就不需要这一步,直接跳到Step2即可。 - Step2: 下载RT1170_LIN_Porting_Demo_Master.7z代码到作为Master节点的IMRT1176-EVK板; - Step3: 下载RT1170_LIN_Porting_Demo_Slave_with_Auto_Baud_Rate.7z代码到作为Slave节点的IMRT1176-EVK板,如果需要使能自动波特率调整,需要配置宏linUserConfigSlave.autobaudEnable = true; 代码中默认是打开的。 实验结果   打开两个IMRT1176-EVK板串口,波特率配置115200,单击RT1176 Master节点上的按键SW7,便可以启动Master节点开始发送数据,通讯波形和串口打印信息如下两张图所示。   代码移植的几个难点   1. LIN通讯协议栈的调度流程的理解,包括Wakeup段,Break段,Sync段,PID段,Data段的状态切换和跳转,每个段的超时监测和错误处理,其核心思想有两个:一个在于LIN的RX引脚要不断去monitor TX引脚的状态,然后去切换状态机,具体调度的流程在后文会详细介绍,这里不展开。第二个是准确获取在每个段的定时器时间,尤其是超时超过一个overflow周期的情况,需要对timerGetTimeIntervalCallback0函数有理解。 2. 自动波特率调整功能的支持,该功能的原理是测量SYNC段的8个脉冲的脉宽,如果每个脉宽差异在2%范围内,再根据脉冲宽度去判断对应的波特率。在原来KW36的代码中是使用TPM的Overflow中断来作为计时,Edge中断来触发,而RT1176没有TPM,只能使用Qtimer (Qtimer功能上要更强于TPM),但是不巧的是Qtimer不支持Overflow中断(参见芯片ERRATA 050194),所以只能使用compare中断来实现类似的功能,而原有的计时定时计算都是基于overflow的,因此就需要对定时器部分的代码做大范围的更改。 应用中考虑到timerGetTimeIntervalCallback0函数在自动波特率调整时和超时监测处理时的一致性,最好使用同一个Timer的同一个channel,这就需要这个Timer既支持普通的定时中断模式,又支持input capture功能。对于TPM来说,是无法实现的因为两次在寄存器配置上时互斥的, 参见下图。幸运的是Qtimer支持这个feature,只是需要根据SDK代码做些配置 前面提到,需要QTimer支持input capture功能, 触发信号是LPUART_RX引脚的信号,需要硬件loop到Qtimer支持的硬件引脚上,对于KW36来说,只需要把这两个物理引脚连接在一起即可,但对RT1176来说, 只有这一步还不行,还需要对XBAR进行配置,将Qtimer的TIMER 1的触发引脚(合计有4个物理引脚)Link到QTIMER对应的Channel上,因为RT1176有4个QTimer,每个Qtimer有4个通道,标称的Qtimer trigger pin有4个,那具体哪个pin触发哪个QTimer的哪个通道,是需要配置的。如果客户没有使用过XBAR配置起来有难度,还好MCUXpresso config tool支持配置,可以简便的完成配置。示例代码和触发关系如下,如果实际硬件使用的物理引脚有区别,需要对应修改。 RT的XBAR功能非常强大,或许可以不使用外部的物理连线,直接将Qtimer的出发引脚的信号直接在内部Loop到LPUART_RX引脚,这样就更加灵活,此处只提供一个思路,不再进一步延伸。 IOMUXC_GPR->GPR15 = ((IOMUXC_GPR->GPR15 & (~(IOMUXC_GPR_GPR15_QTIMER4_TRM1_INPUT_SEL_MASK | IOMUXC_GPR_GPR15_QTIMER4_TRM2_INPUT_SEL_MASK)))/*Mask bits to zero which are setting*/ | IOMUXC_GPR_GPR15_QTIMER4_TRM1_INPUT_SEL(0x00U) /*QTIMER4 TMR1 input select: 0x00U*/ | IOMUXC_GPR_GPR15_QTIMER4_TRM2_INPUT_SEL(0x00U) /*QTIMER4 TMR2 input select: 0x00U*/ ); 4. 在状态机切换和超时以及错误处理过程中,经常会看到两种模式Sleep模式和Idle模式,区别是什么呢? LIN_LPUART_GoToSleepMode: 函数会关闭 Break 中断, RX 接收中断,帧错误中断,保留 RX 边沿 中断 ; LIN_LPUART_GotoIdleState 函数会打开 Break 中断, RX 接收中断,帧错误中断,关闭 RX 边沿中 断 ; 实际通讯波形   Master 作为 Subscribe 角色时,发送 Header ,由 Slave 发送 Respone Master 作为 PUBLIC 角色时,同时发送 Header ,以及 Respone 按照调度表依次发送 LI0_lin_configuration_RAM 数组定义的 PID 数据 static uint8_t LI0_lin_configuration_RAM[LI0_LIN_SIZE_OF_CFG]= {0x00, 0x30, 0x33, 0x36, 0x2D, 0x3C, 0x3D ,0xFF}; Qtimer 准确读取 wake up 信号的脉冲宽度 Slave 使能 Auto baud rate 后读取到的每个脉冲宽度数据 免责声明: THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" AND *ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED *WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE DISCLAIMED.* IN NO EVENT SHALL THE COPYRIGHT HOLDER OR CONTRIBUTORS BE LIABLE FOR ANY DIRECT, *INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING, * BUTNOT LIMITED TO, PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES; LOSS OF USE, * DATA, ORPROFITS; OR BUSINESS INTERRUPTION) HOWEVER CAUSED AND ON ANY THEORY OF * LIABILITY,WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE * OR OTHERWISE)

引言 FRDM-KW36包含带有32 kHz晶体振荡器的RTC模块。此模块为以极低功耗模式运行的MCU生成32 kHz时钟源。该振荡器包括一组用作CLOAD的可编程电容器。改变这些电容器的值可以改变振荡器提供的频率。 此可配置电容的范围为0 pF(禁用电容器组)至30 pF,步长为2 pF。 这些值是通过组合启用的电容器获得的。可用值为2 pF,4 pF,8 pF和16 pF。可以完成这四个数值的任意组合。如果可以使用外部电容器,建议禁用这些内部电容器(清除RTC控制寄存器SFR中的SC2P,SC4P,SCS8和SC16位)。 要调整振荡器提供的频率,必须首先能够测量该频率。使用频率计数器将是非常好的,因为它提供了比示波器更精确的测量。您还需要输出振荡器频率。要输出振荡器频率,以任意一个蓝牙演示应用程序为例,您应该执行以下操作: 调整频率示例 本示例将利用Connectivity Software Stack中的心率传感器演示(freertos版本),并假定开发人员具有从SDK到IDE导入或打开项目的知识。 1.从SDK中打开或克隆“心率传感器”项目。 2.在工作区的board文件夹中找到board.c和board.h文件。 3.如下图所示在board.h文件中声明一个void函数。该函数将RTC管脚复用设置为输出到PTB3并能够测量频率。 4. 如下所示在board.c文件中开发BOARD_EnableRtcClkOut函数。 5. 代码如下: 6. 在BOARD_BootClockRUN(board.c文件)之后立即在hardware_init函数中调用BOARD_EnableRtcClkOut函数。 7. 在工作区的board文件夹中找到clock_config.c文件。 8. 在文件顶部添加以下定义。 9. 在BOARD_BootClockRUN函数内部(也在clock_config.c文件中)搜索对函数的CLOCK_CONFIG_EnableRtcOsc调用,然后通过上述任意定义来编辑变量。 10. 最后,在项目源文件夹中的“ preinclude.h”文件中禁用低功耗选项和LED支持: 此时,您可以在PTB3中进行测量,并使用频率计数器进行频率调整。每次对电路板进行编程时,都需要执行POR以获得正确的测量。下表是从FRDM-KW36板版本B获得的,可用作调整频率的参考。 请注意,电容不仅由启用的内部电容组成,还包括封装,内部走线,芯片焊盘和PCB走线中的寄生电容。因此,尽管下面给出的参考测量值应接近实际值,但您还应该在电路板上进行测量,以确保频率是专门针对您的电路板和布局进行调整的。 Labels: KW     KW35 | 36 kinetis kw36a

  Overview   Vehicle-to-Everything (V2X) technology enables cars to communicate with their surroundings and makes driving safer and more efficient for everyone. By making the invisible visible, V2X warns the driver of road hazards, helping reduce traffic injuries and fatalities. In addition to improving safety, V2X helps to optimize traffic flow, reduce traffic congestion and lessen the environmental impact of transportation. V2X is a key component for full autonomous driving. V2X need message package signing & verification which need high CPU loading if used CPU. Qualcomm recommend their customers to use NXP i.MX8X/XL which have HSM as their modem’s companion chip. Two major components in the system: RSU (Road Side Unit) and OBU (On Board Unit).

  Overview   Since 1996 in EU and since 2000 in Europe, the OBD (On-Board Diagnostics) is mandatory for all the cars manufactured. This protocol is used to verify the smoke emissions and check if any car is between the parameters stablished in every country. Also detect engine failures without need to check the engine manually, identifying accurately the problems reducing the repairing time and cost. OBD-II is a sort of computer which monitors emissions, mileage, speed, and other useful data. OBD-II is connected to the check engine light, which illuminates when the system detects a problem. Scan tools can be used to make sense of the diagnostic trouble codes and collect data on other aspects of vehicle’s performance.   Use Cases Hotspot in the CAR Geofences and speed limits Driving habits tracking Insurance and Rental Entertainment   Block Diagram   Products Category Name MCU Product URL 1 MIMXRT1050-EVK: i.MX RT1050 Evaluation Kit Product Description 1 The i.MX RT1050 EVK is a 4-layer through-hole USB-powered PCB.

In BLE spec there is no standard wireless pass through profile, so different chip vendors have their own implementations, which is also called Proprietary Profile, the compatibility is a big challenge. There are two wireless pass through demos in NXP BLE demos. For QN90XX chip, it’s called QPP. For KW3X, it’s called wireless UART.  The wireless UART is more complex. It doesn’t support always-connection and have many limitations for the app. The common BLE debug tool app on phone side cannot communicate with it, while the QPP can work well.  This demo code is target to port the QPP profile to KW3X SDK, which can simplify user’s development.

As more and more car OEM are considering to use phone as the car key, which need to localize the driver’s position, most customers prefer to use RSSI based solution as it can be supported by current phone directly, while PDE and AOA is not compatible with current phone.  Common RSSI Localization method is acquiring advertising channels, It’s easy, but it is hard to make authentication, can be attacked easily and have low anti-interference ability as it only have 3 channels. So customers are asking for a new method to monitor the data channels with hopping.  This demonstration system implement data channel’s RSSI tracing and monitoring of 4 BLE connections at the same time, and designed a GUI to simplify the steps to setup the demo system, and view the result visually.
