ULPbench score too low for STM32L432KC
I used X-NUCLEO-LPM01A, STM32 Power shield to measure power consumption of STM32L432KC and got ULPbench score 0.04 which seems extremely low. Normally, according to the examples I saw, the score should be above 100. All my STM32 board is doing is a ...

SPI DMA STM32H7 SPI Slave response issue
I'm trying to implement a SPI Slave using a circular DMA on the STM32H7.I'm able to correctly receive the bytes sent from a master.I have enabled an interrupt on the rising edge of the chip select to read out the sent bytes at the end of a transmissi...
LL_RCC_GetTIMClockFreq doesn't account for the APB Prescaler - is this correct?
I'm writing an application which uses a timer (TIM2 in this case) to track communication timeouts. So the timer period changes periodically, it might be an inter-byte gap timeout at one point and an inter-packet timeout the next.I'm using LL_RCC_GetT...
HAL_UART_Receive() on STM32F407 is receiving only one byte a time irrespective of amount of data being transmitted on transmitter side.
Hello,Am using STM32F407 (Discovery board). This is connected with a PC which is sending 100 bytes of data and realized that only 1 byte is received and remaining 99 bytes are lost. Below is the code excerpt running on STM32F407 while(1) { ...

Image overlapping flash banks on STM32H745
Hello,We are using the STM32H745 dual core series, and have an image size that is nearing the single flash banks limit of 1MB. We won't be using the swap bank feature at any point. Will there be issues if the image overlaps the second bank?
