    • RE: coolpi 4b(ubuntu20.04系统)如何做超频设置(最高能提高到多少?)?

      @零度灬救赎 目前2.4G最高,不支持再超到更高频率。强行超频可能会导致CPU物理损坏。建议增加散热措施,让CPU持续工作在高频即可。

      @wuming 按照如下方法操作,格式化EMMC
      1.按住中间的loader按键同时短按复位按键,机器就会进入maskrom模式,如下图所示:

      2.选择loader文件,选择EMMC,点击download,等待完成以后点击Eraseall。即可完成EMMC擦除。

      3.短按复位按键,快速按三次pwr按键,机器就会进入MSC模式

      4.使用etcher选择固件和MSC设备烧录即可。

    • CAN bus testing tools and commands

      Test tools

      Canutils is a commonly used CAN communication testing toolkit that includes five independent programs: canconfig, candump, canecho, cansend, and cansequence. The functions of these programs are briefly described as follows:

      • canconfig
        The parameters used to configure the CAN bus interface mainly include baud rate and mode.

      • candump
        Receive data from the CAN bus interface and print it in hexadecimal format to standard output, or output it to a specified file.

      • canecho
        Resend all data received from the CAN bus interface to the CAN bus interface.

      • cansend
        Send the specified data to the specified CAN bus interface.

      • cansequence
        Automatically repeat the increment number to the specified CAN bus interface, or specify the receive mode and verify the received increment number.

      • ip
        Configuration of CAN baud rate, functions, etc.

      Common commands

      • Query current network devices:
      ifconfig -a
      
      • CAN start:
      ip link set can0 down  %(#000000)[//Close CAN]
      ip link set can0 type can bitrate 500000 %(#000000)[//Set bit rate of 500KHz:]
      ip -details -statistics link show can0 %(#4d845e)[//Print can0 information:]
      ip -details -statistics link show can0 %(#538864)[//Start CAN:]
      
      • CAN sending:

      Send (standard frame, data frame, ID: 123, date: DEADBEEF):

      cansend can0 123#DEADBEEF
      

      Sending (standard frame, remote frame, ID: 123):

      cansend can0 123#R
      

      Send (extended frame, data frame, ID: 0000123, date: DEADBEEF):

      cansend can0 00000123#12345678
      

      Sending (extended frame, remote frame, ID: 0000123):

      cansend can0 00000123#R
      
      • CAN reception:

      Start printing and wait for reception:

      candump can0

          if cv2.waitKey(1) & 0xFF == ord('q'):

      cap.release()
      cv2.destroyAllWindows()
