7. Write the application program using the library functions given in the user manual for each
peripheral and compile.
Caution: Only the ST7lib_config.h and the files contained in the configuration subdirectory of
6.2 USING THE COMMUNICATION PERIPHERALS LIBRARY
6.2.1 SCI
This part of the user manual contains the detailed description of all the functions for the SCI.
An example ‘C’ program has been given at the end.
You can select either of the two Transmission/Reception modes of SCI implemented inside
the library. For selecting any of the possible modes described below you need to select the
corresponding #define statement inside the ST7lib_Config.h file
Polling:
With this mechanism the data can be transmitted or received by polling the status of the cor-
responding flag. Here both the single as well as continuous Transmission/Reception is pos-
sible. In continuous Transmission/Reception, control will be inside the function until all the re-
quested data is Transmitted/Received and hence the application software has the risk of
losing control if there is a breakdown in communication (the SCI mode is disabled). To avoid
this risk, you can use the single byte transmission with some time out protection inside this
mechanism. This mechanism can only be used with the SCI in half duplex mode. To use this
mode you must have selected the following # define labels inside the ST7lib_config.h file:
For SCI2 in ST72F561 device the labels are:
Interrupt driven without communication buffer:
With this method data can be Transmitted/Received either in single or continuous mode using
interrupts. In continuous mode the user data is directly being read/written from/to the ad-
dresses passed by the user. After each byte of data transfer an interrupt is acknowledged and
the control goes to the interrupt subroutine. The main advantage of using interrupts rather
than polling is that control does not stay in the function till the last data is Transmitted/Re-
ceived and hence the SCI can be used in full duplex mode. Here, you should take care not to
read/write the user buffer until the Transmission/Reception is complete. To use this mode you
must select the following # define labels in the ST7lib_config.h file:
SCI_ITDRV_WITHOUTBUF_TX
SCI_ITDRV_WITHOUTBUF_RX
For SCI2 in ST72F561 device the labels are:
SCI2_ITDRV_WITHOUTBUF_TX
SCI2_ITDRV_WITHOUTBUF_RX
the examples folder are user-modifiable, the rest of the source files are write protected.
Changing peripheral source files and header files may adversely affect the library operations
and this will be complicated to update when there are new library releases.
