Overview

OSS-EC (Open Source Software for Eectronic Components) is a generic term for open source software (OSS) and related documentation for electronic components (components).
The purpose of OSS-EC is to standardize electronic component programs so that they can be developed with high quality, at low cost, and in a short time.

Feature High portability

  • Standard API by component type
  • Supports a wide variety of RTOS
  • Support for a wide variety of HALs
  • License free (but comply with OSS-EC Terms of Use)
  • Provides many documents

* Library functions are provided with functions to assist your application. It is up to the user to decide whether or not to use them.

API

The API is determined by selecting components and BSL functions. For detailed specifications, please refer to the respective BSL specifications.

rtn_type bsl_12345678( arg_type tbl_ABCDEF);
exp) float bsl_00000058( tbl_adc_l_t tbl_S58LM20A );
     rtn_type       float
     bsl_12345678   bsl_00000057
     arg_type       tbl_adc_l_t
     tbl_ABCDEF     tbl_S58LM20A

It is recommended that the API name be redefined and used as follows.

sample/main.cpp (Mbed)

// redefine
#define tempreture_read bsl_00000058
#define humidity_read   bsl_00000058
#define tbl_temperature tbl_S58LM20A
#define tbl_humidity    tbl_CHS_MSS
typedef tbl_adc_l_t tmp_struct;
typedef tbl_adc_l_t hmd_struct;
float tempreture_read( tmp_struct );
float humidity_read( hmd_struct );
void ap( void )
{
    float val_temperature;  // Temperature [degree celsius]
    float val_humidity;     // Humidity [%RH]
    do{
        // Read of Temperature Sensor
        val_temperature = tempreture_read( tbl_temperature );
        // Read of Humidity Sensor
        val_humidity    = humidity_read( tbl_humidity );
        // Application cycle wait
        thread_sleep_for( iSensor_Cyc );
    }while(true);
}

OS support

OSS-EC provides BSLs supporting many operating systems as shown in Fig. 3.
