I. Introduction:
Microchip's MPLAB X + Harmony software development platform configures the hardware interface of the board through the BSP (Board Support Package) file. Users only need to select the corresponding BSP file to complete the hardware configuration, eliminating a lot of hardware debugging. jobs.
At the same time, Harmony provides the BSP configuration file of the Demo board released by Microchip's official website, which is convenient for users to learn and use. So, can customers create BSP files based on their own hardware design for different
What is the project to use? This article describes a method for creating and using a customer's own BSP file based on MPLAB X + Harmony
Second, hardware tools and software platforms:
hardware:
1. PIC32MZ EF Starter Kit
software:
MPLAB X: v3.65 or newer
MPLAB XC32 compiler: v1.44 or newer
MPLAB Harmony: v2.04 or newer
Debugging tools:
MPLAB ICD 3
Third, the steps:
(1) Establish a Harmony project and name it "bap_test"
Select File->New Project in MPLAB X to create a 32-bit Harmony project and name the project.
(2) Open the MHC tool and configure the project.
(3) You can select an existing BSP file and modify it based on it.
(4) Modify the BSP configuration according to the actual situation of the board. As a demonstration, only the three pin names of the LED output are changed in this paper.
(5) Save the configuration, name the board and configuration, remember to check “Add to MPLAB Harmony Board Listâ€.
(6) Generate code.
(7) Create a new Harmony project and select the board as the newly generated board "MY_BOARD".
(8) Regenerate the code using MHC.
(9) The project generated by this way has used a custom configuration, we can get from Pin
As seen in Setting, the configuration is already defined by the customer.
Fourth, summary:
Customizing the bsp file allows Harmony to more easily adapt to the board developed by the customer, which undoubtedly expands the Harmony application scenario.
