OLED-SPI完整资料，支持多种单片机

//------------------------------------------------------------------------ // Readme.txt //------------------------------------------------------------------------ This project is configure to get you up and running quickly using CodeWarrior with the Freescale MCF52259 board. This project provides full support for the selected board. The created project provides Standard IO Support through console and terminal window. Sample code for the following language: - C //------------------------------------------------------------------------ // Memory Maps //------------------------------------------------------------------------ The Hardware has the following memory map: # MCF52259 Derivative Memory map definitions from linker command files: # __IPSBAR, __RAMBAR, __RAMBAR_SIZE, __FLASHBAR, __FLASHBAR_SIZE linker # symbols must be defined in the linker command file. # Memory Mapped Registers (IPSBAR= 0x40000000) ___IPSBAR = 0x40000000; # 32 Kbytes Internal SRAM ___RAMBAR = 0x20000000; ___RAMBAR_SIZE = 0x0000FFFF; # 512 KByte Internal Flash Memory ___FLASHBAR = 0x00000000; ___FLASHBAR_SIZE = 0x00080000; //------------------------------------------------------------------------ // Project Structure //------------------------------------------------------------------------ The project generated contains various files/groups: - readme.txt: information for this project - Sources: application source codes, user customizable startup code, uart library, exception table - Includes: derivative and board header files, ... - Libs: runtime and libs - Project Settings: linker command files for the different build targets, the initialization and memory configuration files for the hardware debugging, the common startup code, etc... //------------------------------------------------------------------------ // Build Targets //------------------------------------------------------------------------ - CONSOLE_INTERNAL_RAM: This project target is setup to load and debug code from internal RAM. It should be used during your application development. The application outputs to the CodeWarrior's console window. - INTERNAL_RAM: This project target is setup to load and debug code from internal RAM. It should be used during your application development. This is the very basic project that outputs to the UART. You needs to connect a Terminal Program to see the output. - INTERNAL_FLASH: This project target is setup to load and debug code in Internal FLASH. This is the very basic project that outputs to the UART. User needs to connect the terminal to see the output. =================================================================== WARNING regarding debugging new project wizard code with CCS-SIM =================================================================== The CCS-SIM is an instruction set simulator, it does not implement any peripherals. The new project generated by the wizard are using startup code performing some hardware peripheral initializations. When debugging with the CCS-SIM it might happen that the simulation stuck on loop using non implemented peripheral register flag as condition (PLL initialization as example). In this case, you should either: - move the PC to next statement - use a skip point - define a simulator specific macro which used when define allos you to comment out the unwanted code in order to debug with CCS-SIM =================================================================== WARNING regarding code located in RAM =================================================================== Many possible ColdFire target processors have an external bus, so you can use large external RAM devices for debugging applications during development. But some processors do not have an external bus, so you must accommodate applications in on-chip memory. Although this on-chip RAM accommodates this CodeWarrior project, it probably is too small for full development of your application. Accordingly, for a processor without external bus, you should locate your applications in flash memory. //------------------------------------------------------------------------ // Flashing the code //------------------------------------------------------------------------ 1. Select the appropriate project target and build it 2. Make sure the correct remote connection is selected in the Remote Connection debugger panel 3. In the CodeWarrior IDE menu, select Project > Set Default Project and select your project 4. In the CodeWarrior IDE menu, select Project > Set Default Target and select the project target that has the code you want to flash 5. In the CodeWarrior IDE menu, select Tools > Flash Programmer 6. Go to the flash programmer Target Configuration panel, click Load Settings 7. Browse to the <your project location>\cfg sub folder and select the flash settings xml file matching your build target 8. Check that Use Custom Settings checkbox is not selected 9. Go to the Erase/Blank Check panel, select the All Sectors option and click Erase 10. Go to Program/Verify panel, click Program 11. Your code should now be flashed //------------------------------------------------------------------------ // Terminal Settings //------------------------------------------------------------------------ In case the UART is supported, the terminal should be setup with: - 19200 bauds, - 8 data bits, - no parity, - 1 stop bit, - no flow control. Please check this file in the project. //------------------------------------------------------------------------ // Getting Started //------------------------------------------------------------------------ To build/debug your project, use the CodeWarrior IDE menu Project > Debug or press F5. This will launch the debugger. Press again F5 in the debugger (or the CodeWarrior IDE menu Project > Run) to start the application. The CodeWarrior IDE menu Project > Break stops the application. //------------------------------------------------------------------------ // Adding your own code //------------------------------------------------------------------------ Once everything is working as expected, you can begin adding your own code to the project. Keep in mind that we provide this as an example of how to get up and running quickly with CodeWarrior. There are certainly other ways to handle interrupts and set up your linker command file. Feel free to modify any of the source files provided. //------------------------------------------------------------------------ // Additional documentation //------------------------------------------------------------------------ Read the online documentation provided. In CodeWarrior IDE menu, select Help > CodeWarrior Help. //------------------------------------------------------------------------ // Contacting Freescale //------------------------------------------------------------------------ For bug reports, technical questions, and suggestions, please use the forms installed in the Release_Notes folder.
