I am using STM32F446RE. I am using the STM32CubeIDE. As STM32F446RE is Cortex-M4 based processor I have also gone through the M4 generic user guide and found that the range of NVIC_ISER0- NVIC_ISER7 is 0xE000E100- 0xE000E11C. But when I ran the code ...

I have configured the GPIO for I2C1(Alternate function 4) and enabled the Clock for I2C1. After that I am trying to enable the ACK. but not able to enable that.. Also tried for I2C2 and I2C3 facing the same issue.//enable the clock for the I2C periph...

Hi @e.oztoklu ,I got some temporary solution. Instead of checking the NVIC register in Cortex_M4 check into the microcontroller specific NVIC section. There the addresses are correct.Ex. In my case:I see the below addresses which are correct. but he...

Yeah I copied correct file only. I checked the SVD file. Only ISER0, ISER1 and ISER2 are there. Others are not there. I also tried adding them manually. Still I see the same issue. ISER0 -> 0xE000E100 .this is correctbut ISER1-4 are not correct here...

@TDK As you said I also tried to enable PE after I2C1 init but PE and START condition are not getting enabled.START:PE:Am I missing anything?

@TDK No Actually I am trying to do I2C1 inits. So I am trying to set the ACK bit (Bit 10 ) in the I2C1_CR1 register so that the acknowledge will be enabled. I am not starting the communication yet. PE=1 when the communication will be started. Am I r...
