Introduction Background There is not an official data for PCIe latency and performance, while some customers pay attention to and request these data. This paper utilizes Lmbench lat_mem_rd tool and DPDK qdma_demo to test the PCIe latency and performance separately. Requirement 1) Plug Advantech iNIC (LX2160A) into LX2160ARDB. 2) Configure EP ATU outbound window at console. 3) Apply the patch to lmbench-3.0-a9, and recompile lmbench tool. 4) There is qdma_demo in iNIC kernel rootfs by default.

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   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.

The Kinetis KW36A/35A/34A MCUs feature AEC Q100-Grade 2 temperature range qualification while the KW36Z/35Z feature and Industrial qualification. 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.

Description Earlier this year NXP organized a promotional opportunity for amateur radio enthusiasts to use their creativity and build their own power amplifier designs. NXP received numerous creative submissions in this competitive Homebrew RF Design Challenge. We appreciate the dedication and enthusiasm from the community that made this contest a success. First place winner An MRF101AN broadband amplifier design with 1 W Input, 100 W Output 1.8-54 MHZ Amplifier deck. (For more information visit:NXP MRF-101 - RFPowerTools )  It is an amplifier with a bandwidth of 1.8MHz to 54MHz. Maximum output power of 100W up to 30MHz and 70W up to 50MHz. Maximum power supply 50V to 4A, with a Voltage Standing Wave Ratio of 1.5:1 maximum. The design dimensions of the PCB is 5x5 cm (2x2 in).  and  310g weight including fan and heat sink. Second place winner A 600W broadband HF amplifier using affordable LDMOS devices (For more information visit: https://qrpblog.com/2019/10/a-600w-broadband-hf-amplifier-using-affordable-ldmos-devices/  ) This project is meant to demonstrate the capabilities of the MRF300 transistors as linear broadband devices in the 2-50MHz range and to be used by radio amateurs as a starting point for a medium-high power amplifier. This is also my entry to the NXP Homebrew RF Design Challenge 2019. To achieve the target of 600W output while also minimizing the level of even-number harmonics, a “push-pull” configuration of two transistors is used. Luckily, the manufacturer made it easy to design the PCB layout for such a thing by offering two versions (the MRF300AN & MRF300BN) that have mirrored pinout. The common TO-247 package is used, with the source connected to the tab. Each individual MRF300 LDMOS transistor is specified at 330W output over a 1.8-250MHz working frequency range, a maximum 28dB of gain and over 70% efficiency. The recommended supply range is 30-50Vdc. By studying the specifications, it looks like with correct broadband matching and some operational safety margin we can get close to 600W output at a voltage of around 45V across a resonably large bandwidth; the aim is to cover 1.8 to 54MHz. Main challenges when designing this amplifier are related to achieving good input and output matching over the entire frequency range as well as maintaining high and flat gain. Good linearity and a low level of harmonic products are mandatory. As the TO-247 is not a package specifically designed for high-power RF, there are some challenges with thermal design and PCB layout as well. Information taken from the essay by the winner. Third place winner A High Efficiency Switchmode RF Amplifier using a MRF101AN LDMOS Device for a CubeSat Plasma Thruster (For more information visit: Research - SuperLab@Stanford ) The Class E amplifier utilizes the active device as a switch, operating in only cutoff (off) and saturated (on) conditions. This minimizes the overlap of voltage and current, reducing losses in the active device. To further reduce loss the Class E amplifier utilizes an inductively tuned resonant network to achieve zero voltage switching, bringing the voltage across the switch to zero before turn on, eliminating energy stored in the output capacitance of the active device that would otherwise be dissipated. This is achieved with an inductively tuned series resonant output filter.  In the Class E amplifier losses are almost entirely determined by the current conducted by the active device so a high drain impedance is desired to maximize efficiency. The drain impedance is ultimately limited by the voltage rating of the switch. For our desired output power of 40W and the maximum voltage rating of 133V for the MRF101AN this impedance is still less than 50 ohms, so a L match circuit is used to match the drain impedance to 50 ohms. The load network in our design provides a drain impedance of 15.4+12.8j. As the MRF101AN will operate in saturation a high drive level is desired. To eliminate the need for a preamplifier and allow for digital control, we use a high speed gate drive chip typically used in switch-mode power supplies, LMG1020, to drive the MRF101AN instead of a RF preamplifier. A resonant network is used to provide voltage gain at the fundamental and third harmonic, providing a quasi-square wave on the gate which helps insure the device remains in saturation. Conclusion It was a close call and highly competitive! Each participant had their own creative, unique and impressive way of displaying the capabilities of these new parts. NXP is always up for new design challenges. Ready for the next challenge?
