Subject: STM32F030F4P6 I2C Slave Transmitter Problem : TXI event triggered more times than requested by I2C master
RM0091, Rev4, 24.7.7 (I2Cx_ISR), Bit 1 TXIS: Transmit interrupt status (transmitters)
[...] Note: This bit is cleared by hardware when PE=0.
JW thanks JW for your Reply, but it doesn't work :(
i try it with this :
I2C1->ISR &= (uint32_t)0xFFFFFFFD; it is stated in RM0091 :
Bit 1 TXIS: Transmit interrupt status (transmitters)
This bit is set by hardware when the I2Cx_TXDR register is empty and the data to be
transmitted must be written in the I2Cx_TXDR register. It is cleared when the next data to be
sent is written in the I2Cx_TXDR register.
This bit
can be written to ‘1’
by software when NOSTRETCH=1 only, in order to generate a
TXIS event (interrupt if TXIE=1 or DMA request if TXDMAEN=1).
Note: This bit is cleared by hardware when PE=0.
i'm even try to add
I2C_StretchClockCmd(I2C1,DISABLE);
etc .. but still no luck.
others ? :).
