You can choose to use 2-byte addressing (only for programs within 64k) or 3-byte addressing as needed. Users can choose the most suitable configuration according to the needs of the application. STM8's C compiler supports multiple memory modes. hex file will be generated in the project output directory (in this example, under the C:\STM8_NewProject1\debug directory). sm8Ĭompile and link the project again, and if successful, a. In hex format In the Project->settings->PostBuild tab, add the following command in the commands column:Ĭhex –fi -o $(OutputPath)$(TargetSName).hex $(OutputPath)$(TargetSName). This file lists the allocation and usage of RAM/FLASH/EEPROM in detail. map file will be generated in the project output directory (in this case, under the C:\STM8_NewProject1\debug directory). After clicking the OK button on View Image In the Project->settings->linker option page, select Category as Output, and then check Generate Map File.

How to observe the final allocation of RAM/FLASH/EEPROM In COSMIC C files? There are two common ways to use assembly language in COSMIC C files: use #asm …#endasm combination format How to initialize variables using assembly language These three are distinguished by different brackets. Note: pragma Directives can be used to locate functions, initialize variables or uninitialized variables. #pragma section //Return to the normal section. …… (any variable that needs to be defined in the. #pragma section //Define the following The uninitialized variables are defined in the. In addition, the pseudo-instruction "pragma" can also be used to define functions or variables in the specified section, for example: Unsigned char unsigned variable temp_B, force its address to be unsigned char temp_C //Define an unsigned variable temp_C, and the compiler will automatically assign an address to it in RAM with an address less than unsigned char temp_D //Define an unsigned variable temp_D, The compiler will automatically assign an address to RAM with an address greater than 0xFF.
Unsigned char unsigned variable temp_A, force its address to 0x00 How does assign variables to the specified address
On the other hand, the compiler doesn't like it being redefined, so that is enclosed by the "#ifdef" and "#endif". Normally _CSMC_ is automatically defined by the compiler, but the IDE does some basic check on its own and the header file complains about compiler not supported. Use the following line for including the header file. STM8S/A Standard peripheral library can be downloaded: hereĮn.stsw-stm8069.zip/STM8S_StdPeriph_Lib/Libraries/STM8S_StdPeriph_Driver/inc/stm8s.h In this case, I'll make an exception as the header file that comes with Cosmic C is missing the register bit definitions.
#Stm8 cosmic manual
it take more effort than reading the darn user manual than to trace through the mess. I see that as much work as trying to untangle a breakout board done in fritzing wiring diagram back into a proper schematic.
#Stm8 cosmic driver
Normally I wouldn't bother downloading the standard peripheral driver from a vendor. Projects / Misc 8-bit uC projectsOriginal post date:
