STM32 MCUs Products

I need to configure CAN filters in such a way that only ID 0x80 and IDs between 0x200 and 0x300 passes all others are not allowed to be passed. How to do that?

I tried in this way but the problem is only 200-300 can pass but 80h is not passed. if i use if else then only 80h is passed not 200-300h. So, the problem is i can pass either 80h or 200h-300h. Not both 80h and 200-300h. #define Filter_ID1  0x80#def...

Why Microcontroller is halted after Power-on Reset?

Hi,I wrote a simple Led blinking program in STM32F303CB.-> On power-on reset Controller is not getting started.-> I used Internal Clock and External Clock-> But the same behavior in both the cases.Thanks.

STM32L552ZE-Q SAI I2S slave pass data to master output

My development board is STM32L552ZE-Q.I want to use SAI slave mode receive i2s signal and SAI master transmit i2s signal.I can observe clock and makesure data in have input.But my data out isn't similar with my input.Does any one can help me, thanks

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 Someone told me that the STM32F100RBT6 is obsolete.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?
