Detailed definition, timing description, performance indicators,
Indicator Light description, external wiring definition, programmable device diagram, function module description, schematic diagram, detailed material list and board
Test and debug the plan. Sometimes the hardware and software of a single board are developed by two developers respectively.
The detailed hardware design provides a detailed guidance for software designers. Therefore, the detailed design report for single board hardware is critical.
Yes. In particular, address allocation, control mode, interface mode, and interrupt mode are the basis for the preparation of the board software, which must be detailed.
Write.
5. Detailed Design of board software
After the software design is complete, the detailed design Report of the software should be completed accordingly.
Programming Language, debugging environment of the compiler, Hardware Description and functional requirements, and data structure. Special emphasis should be placed on:
Detailed design details, including interrupt, main program, subprogram functions, entry parameters, exit parameters,
Local variables, function calls, and flowcharts. In the description of the relevant communication protocols, the physical layer and link layer communication protocols should be described.
Which documents define the communication protocol with the higher level.
6. board hardware process debugging document
During the development process, engineers should submit a process document for each PCB Board to help the management team understand the progress,
The evaluation is carried out, and a reference technical document is also provided to other related engineers. Each time the PCB Board is cast
