SPI TXEIE is not SET even after configured it

I have done some debugging on SPI interrupt problem. So, I have a function that SPI_SendDataIT which means SPI send data with interrupt. the interrupt will be triggered if TXE flag is SET. But we have to enable the TXEIE first. But, what happen is, a...

What is the difference between STM32F100RBT6 and STM32F100RBTB? What is the meaning of the ending 'B'? Someone told me that the STM32F100RBT6 is obsolete. Are there any problems to be expected by exchanging the devices? Best regards Peter

SPI INTERRUPT PROBLEM

I have a code regarding the SPI interrupt, where my STM32F302R8 nucleo as a master while my arduino board as a slave. In this program, I use PB6(stm32) to pin D8(arduino) as my interrupt pin where the interrupt triggers when D8 goes to LOW.How my pro...

how to build a hex that with external section data?

In STM32L4R9AI discovery board, the project includes const variables of graphical data.the data is placed as a separate section and will be flashed in the external flash.but after build, the variables are not inclued in the hex file.how to add the ex...

I am using STM32L0 and I want to run RTC in my custom board. I using Internal LSI clock for RTC. When I set Alarm for 60 sec it is generated in around 54 sec so i think RTC is running faster . So how can i calibrate it?

Compiler not checking ram overflow in local variables?

Stm32CubeIDE v1.6.1STM32 F1 library v1.8.4New, empty project.Something simple as this comples without any error or warning in a stm32f103.It has 20KB ram, but for some reason the compiler doesn't care that I'm allocating 64KB!Of course, it causes a ...
