specific Embodiment

[0037] Goal: configure Can communication, realize standard frame, baud rate 500k, pins use P3.12 and P3.13.

[0038] 1. If figure 2 As shown, first use the host computer to enter the Can configuration interface, where we can check and configure according to our actual needs.

[0039] 2. Click the "OK" button to confirm that the current module is a module that needs to be edited by Mcal, such as image 3 shown.

[0040] 3. The upper computer starts to search the list to determine which registers need to be configured. The specific method is that each control of the upper computer corresponds to several fixed registers.

[0041]4. When the list of registers to be configured is determined, search for the values ​​to be written into the registers according to the data configuration in the host computer control.

[0042] For example, if the baud rate is configured as 500K, then the retrieved registers to be configured are CAN_NBTR0 and CAN_NFCR0, and then search the value list...

Abstract

The invention provides a visual programming method used for an integrated chip. An object-oriented design idea theory is employed, when a chip is programmed, a man-machine conversation mode is employed, and therefore the programmer only needs to select functions which the chip needs to use with no need of facing a register of a microcontroller. According to the invention, with respect to the programming part of the integrated chip, functions and read-write data of the register are selected by means of precompiled statements, and the visual programming method is suitable for any embedded software development project. According to the invention, the code handwritten workload is reduced, and the working efficiency is improved; the code compiling error rate is reduced, and even errors are avoided. The code compiling format and the register configuration method are normalized, and the programmer only needs to determine the function of the hardware resource and does not need to pay close attention to the concrete usage method of the hardware resource and the corresponding register configuration method. The visual programming method is only correlated to different configurations of the user, and is uncorrelated to the programmer, and the program readability is improved.

Description

technical field [0001] The invention relates to the technical field of development methods for integrated chip programming, in particular to a visual programming method for integrated chips. Background technique [0002] Since the automotive electronic control system is composed of multiple ECUs, the functions of each ECU are independent and the development process is independent, and there are joint work and mutual constraints between each other. However, the current embedded software development is mainly handwritten codes, with heavy workload, high error rate, poor standardization and readability, resulting in continuous increase in development costs and cycles. Therefore, in order to ensure the high efficiency and stability of the main control chip programming of each ECU, the above problems should be avoided, and a more advanced integrated chip programming method should be developed. [0003] The software part of the ECU can be divided into three layers in general, nam...
