Library Description
The library covers all the necessary functions that enables the usage of the LEM click board.It offers reading from output register and calculations that result in relatively accurate measurement of current passing through the conductor in amperes and milliamperes.
Key functions:
uint16_t lem_dataRead()
- Function is used to read data from output register.float lem_getCurrentAmps()
- Function is used to read current in amperes.float lem_getCurrentMilliAmps()
- Function is used to read current in milliamperes.Examples description
The application is composed of the three sections :
void applicationTask( ) { current = lem_getCurrentMilliAmps(); mikrobus_logWrite( "Current in milliamperes: ", _LOG_TEXT ); FloatToStr( current, logTxt ); mikrobus_logWrite( logTxt, _LOG_TEXT ); mikrobus_logWrite( "mA", _LOG_LINE ); Delay_ms( 1000 ); mikrobus_logWrite( "-----------------------", _LOG_LINE ); }
Other mikroE Libraries used in the example:
SPI
UART
Conversions
Additional notes and informations
Depending on the development board you are using, you may need USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
