Table 70. I2Cs_GetBuffer
Notes:
– The above function is only for I2C_POLLING_RX mode.
– Control from this function comes only after receiving a STOP or any Error condition.
Caution: You can lose the control if I2C is disabled while using this function.

nication proceeds according to the I2C protocol. This function should be called again to de-
tect the next event (START / STOP).
I2Cs_ErrCode_t I2Cs_GetBuffer(unsigned char *PtrTo-
Buffer, unsigned char MaxSize)
Receives data bytes in I2C_POLLING_RX mode and
stores in the buffer, whose start address is passed as
pointer. The data reception will discontinue, if any error oc-
curs during reception and the error status will be returned .
*PtrToBuffer
Start address of the user buffer
MaxSize
Maximum size of the buffer
I2Cs_BERR
Bus error is detected
I2Cs_ADDRESS_DETECTED
If address matched condition is detected
I2Cs_GENERAL_CALL
If general call is detected
I2Cs_RX_DATA_OK
If there is no error in data transmission and stop condition
is detected correctly
I2Cs_OVERFLOW_RX
If reception has taken place correctly but overflow condi-
tion has occurred
1. You must define I2C_POLLING_RX mode in
ST7lib_config.h.
2. I2C communication must be detected through the
I2Cs_GetCommMode.
