How do I know at preprocessing time which compiler option was chosen between FPv5-D16 and FPv5-SP-D16?
The __SIZEOF_FLOAT__ and __SIZEOF_DOUBLE__ macros give the same result in both cases.

PROBING PINS/LOGICAL ANALYZERS
Hello ST community,I am using STM32L476RG nucleo board and I am interested in reading the boards pin states while running , especially I would like to debug the serial protocols like SPI, I2C, ...I tried with Cube Monitor but it seems, it is only use...
CAN BUS Loopback mode using HAL Libraries (Adafruit STM32F405 Feather)
Hello, i am new to HAL Libraries. i am learning to work with CAN BUS using HAL Libraries. I want to test the CAN LOOPBACK MODE with Adafruit STM32F405 Feather .Can any one please post an example using HAL Libraries.Thanks in advance.
Double interrupt
I use STM32L552RET.I want to let DMA transfer end interrupt in the 1ms timer interrupt.How to achieve？
Fastest possible way to receive data from GPIO input
Hello everyone.I want to receive data from AD8283 which is a 12 bit ADC. It has a clock input signal and data will be updated to its 12 bit data signals at each rising edge of clock. For synchronization between ADC and microcontroller I use AD9512 wh...
Resolved! How to generate periodic alarm interrupt from RTC
Hello,I am quite new to STM32G0 based development. I want to generate periodic alarm interrupt from RTC (e.g. RTC should generate an interrupt at every 5 minute, 4 second and 400msec). Is it possible to generate interrupt like this? I tried various w...
I always getting 0xff in my SPI RX Buffer
I used the STM32F401 discovery board which has an L3GD20H gyroscope sensor communicated with the MCU via SPI1, I made the necessary configuration by Cube MXI tried to read the device ID of the gyroscope but each time I received 0xff,can someone help ...
How to specify RAM location ?
hi, i have an stm32f103 with me ,basically when i run it on keil in simulation mode , i have allotted space in RAM to store variables and data in the picture below ,and although when i look at the address where ram starts at (0x200000000), there is n...
Comparison between SDMMC performance of H7 series and a question...
Dear experts,1-Has anyone compared the "speed of data transfer" practically in STM32H7 series to transfer multiple blocks of data(between a micro SD card and the internal RAM),in these conditions (mentioned below)? a-Using FATFS in DMA mode b-Using H...
