[0004] It can be seen from the above description that at present, when the data card debugging information is output through the serial port, the physical connection of the device is too complicated; and when there is a lot of debugging information to be output, the information output will occupy the CPU (Central Processing Unit, Central Processing Unit) for a long time. processing unit) resources, so that normal business cannot obtain system resources, thus affecting the working efficiency of the data card, and even causing the data card software to crash

Embodiment Construction
[0025] The present invention will be further described below in conjunction with the accompanying drawings.
[0026] figure 1 , figure 2 It has been described in the background technology, and will not be repeated here.
[0027] refer to image 3 A method for outputting debugging information of a data card, the data card includes a debugging information output port, the debugging information output port is a USB port obtained by expanding according to the data card port expansion mechanism, and is specially used for outputting debugging information. The output method includes the following steps:
[0028] Step 301: The debugging information output thread always waits to acquire the semaphore until it successfully acquires the semaphore and enters step 302; the priority of the debugging information output thread is lower than that of other business threads of the data card, so when the debugging information output thread successfully acquires When the semaphore starts to e...

The invention discloses a data card debugging information input method. A data card comprises a debugging information output port, and the method comprises the following steps: 1. a debugging information output thread of the data card scans a debugging information queue of the data card, and if the debugging information queue is empty, step 3 is performed; or step 2 is performed; 2. the debugging information output thread outputs various nodes of the debugging information queue to the debugging information output port; and 3. the output operation of the debugging information of the data card is completed. The technical proposal provided by the invention can help realize the output of the debugging information of the data card without any other physical device.
Description
technical field [0001] The invention relates to a method for outputting debugging information, in particular to a method for outputting data card debugging information. Background technique [0002] Debugging information is very important for R&D personnel. R&D personnel can often get the current program running status and abnormal cause value from the debugging information, so as to quickly locate the problem. Debugging messages need to be output in real time during the running of the program. [0003] At present, in the software platform used for data card product development, the output of debugging information is realized through the serial port, and the realization of the serial port output needs to cooperate with other physical devices. If the development computer connected with the data card has no serial port, such as figure 1 As shown, first connect the development computer 1 with the download board 3 through the flat cable 2, then connect the download board 3 wit...
