How to use the library
6 HOW TO USE THE LIBRARY
The next section gives the standard procedure to be followed for all the peripherals. Some
specific instructions are given in the section 7.2 which have to be followed if you use the com-
munication peripherals.
6.1 STANDARD PROCEDURE FOR ALL PERIPHERALS
Note: This section is only applicable if you are using STVD7 v2.x.
1. Install ST7_LIBx in one directory as per the installation procedure.
2. When starting for the first time, copy the structure from the demo directory.
3. Choose the target device and copy the configuration files (for Metrowerks or Cosmic) from
the devices directory into the user configuration directory.
4. Update the useful paths and link the chosen peripherals files. The source path will refer to
the directory where ST7_LIBx is installed. For example, assuming that you have installed
ST7_LIBx in D:\
a) The following paths will be updated for Metrowerks in the Default.env:
ST7LIB_PT: Change this path to installation of library
TOOL_PT: Change this path to Metrowerks toolchain path
Depending on the peripherals required for the application update the object list in *.prm and
*.mak files.
b) The following paths will be updated for Cosmic in *.mak file
– Update the source path
PATHC: Change this path to cosmic toolchain installation path
LIB_PT: Change this path to library installation path
SRx_PT = $(LIB_PT)\peripherals\periph\C
where x is the no. of source path for each peripheral
where periph is the name of the peripheral used in the application
– Update the include path
CFLAGS = +mods +debug -co $(OBJ_PT) -i $(SRx_PT)
where x is the no. of source path for each peripheral (give the path of all the peripherals
present in the particular device)
– Update the source list
SRC_LIST = $(OBJ_PT)\..\..\source\main.c $(SRx_PT)
where x is the no. of peripheral used
5. Modify ST7lib_config.h file to include the target device, CPU frequency and the communi-
cation mode if any of the communication peripherals is used.
6. Include ST7lib_config.h in main.c
