I2c, initialization

[Hofmann (Antonin Hofmann)]

Hi friends,

1. is the rui_i2c_init() call needed in my RUI code?
   If there is the at-command at+set_config=device:i2c … working, i2c has to be already initialized somehow.
   Should I call full initialization,
   or is rui_i2c.INSTANCE_ID = 1; enough,
   or …

2. in the STM32 i2c device address must be shifted one bit left, for example
   HAL_StatusTypeDef std = HAL_I2C_IsDeviceReady(&hi2c1, SHTC3_ADDR << 1, 10, 1000);
   Is the DeviceAddress in RUI already shifted ?
   int status = rui_i2c_rw(&rui_i2c, RUI_IF_WRITE, SHTC3_ADDR, 0, tx, 2);

Thx Ant

Hi！
at+set_config=device:i2c …
This command is no longer in use, but the interface exists.
The DeviceAddress in RUI already shifted.
