Refer to the following example to see how to incorporate several of the same electronic components in a user program.
Exe :
Two electronic components ABC Memory (I2C type), HAL STM32CubeF4
Step1 Add two ABC codes to “oss_ecal.h”
Make the following settings in “oss_ecal.h” (Ver 01.01.00 or later).
1. Added Components number codes eABC_1, eABC_2.
The API function argument etCMP should be used to select electronic components using this code eABC_1, eABC_2, not eABC.
