STM32L0x1 reference manual says "the memory interface clock is stopped and the RAM is in power-down when in Low-power sleep mode" (DocID025942 Rev 8 p 145). Several pages below it says "In Low-power sleep mode, the Flash memory can be switched off an...
Hi,someone know a practical application of Injected queue of context for the STM32 ADC? I think that it would be more useful if the two JSQR values in the queue stay forever in the queue like a ring buffer.Asantos.
Hello, In STM32F446RE mcu the block diagram shows 2 shift registers , but in STM32F407x spi block diagram it shows only shift diagram . which one is correct ? are these SPI IPs are different on these devices ? please clarify . i have attached the ima...
Hello,There is any schematic example for the connection between uSD and the STM32H7?I'm currently using a OLIMEX E407 with a STM32H7 instead of a STM32F4. It seems that I have problems with the signals integrity. I can read and write with a 1MHz cloc...
I USED KEIL WITH STM32F750VB AFTER COMPILE AND RUN I UNDRESTAND NO HAVE ANY SPACE ADD FOR STACK FIRST VARIABLE ADDRESS IS FIRST MEMORY ADDRESS IF USED PUSH OR PUP CHANGE SOME FIRST VARIABE IN MEMORY HOW CAN RESOLVED THIS PROBLEM
We've been using a NUCLEO-L433RC-P to prototype a low -power PCB and it has served us very well.We're now embarking on a new project where we're actually going to use the NUCLEO and create a PCB with a header to plug the NUCLEO into. I thought this ...
If the LPTIM CNT is close to the ARR value (0xFFFF) and i set the CMPM value, i receive the interrupt immediately (~1ms) instead of the time i set it. Because the LPTIM runs on 32kHz this happens every 2seconds for 4-5 interrupts.I dont seems to find...
Can someone use MSC to send data to SPI or other GPIO Interfaces?I implemented a Project with Cube and now i want to test it by sending data through MSC to any GPIO or LED
I just run across a bug when trying to program the flash.You have to write two 32bit values for programming the flash. But if the first value is 0xFFFFFFFF it does not matter what the second value is. In the end there will always be written 0xFFFFFFF...
Hello,I raised this problem in another topic I posted, but it is with another title and I'm not sure I will get there the help (title might be missleading).I have the problem after sending Slave Address and Register Address and creating a start condi...
