As the STM32L flash is erased the memory cells are set to 0x00 (not 0xFF). Is there a DFU tool that can optimize firmware upgrade that skips programming of blocks already containing 0x00? The DfuSe Demo only has "Optimize Upgrade duration (Remove som...
Hi to all,I'm trying to use the Nucleo F446RE board to switch on an external LED. by using directly the registersIN particular, I have connected the pin PA5 in series with a resistor, a LED and finally with the GND of the board.The code uses is shown...
Hi i wrote sample code to transfer data by spi and use dma i test my code in 3 stepwhen dma transfer complete interrupt disable, when dma half transfer interrupt enable, and without interruptthis is my code ,just i comment interrupt cmd function for ...
Here is an attempt to collect wishes for Cube application code examples:What peripheral(s)What the code should demonstrate functionality in details (and how it can be reused/modified)Should the example runs on a reference board? Any specific HW compo...
I know this could be done with an external chip, but I want to know if it's possible to do it directly in the micro. I will appreciate any suggestions.
Hello everyone.I have an issue with the communication between STM32F427VI to Gemalto PLS-W.The uart that is configured as the following:void MX_USART3_UART_Init(void) { huart3.Instance = USART3; huart3.Init.BaudRate = 230400; huart3.Init.Word...
Hi,I am using two STM32F103 Nucleo boards and STM32CubeIDE.I can see in the oscilloscope the Tx sinal outputs some data when the mode is configured as loopback. But when I switch the mode to normal I can see in the oscilloscope only a short low level...
I've been developing a solution around the STM32H750 that requires external flash to run relatively large firmware images, up to around 2Mb.The NOR Flash part used is the Cypress s25fl064l, in QSPI configuration. It has quad read rates of up to 54Mbp...
Hi,I am using nucleo-476Rg board.I have configured RTC AlarmA ad AlarmB for different timings, then I go in standby mode.The board wakes up from standby on any of the alarm occurrence.Can I know whether it is due to alarm A or alarm B. when it wakes ...
