Hi all,I'm working on an STM32L552E-EV and trying to declare some constant data into the NOR Flash connected on the Octo-SPI interface. I want to have the Octo-SPI in memory-mapped, so that the constant arrays can be accessed easily in my code. To in...
Hi,We are using the OCTOSPI2 on a H735 in memory map mode.We are copying 32 bits values one by one, from the internal RAM to the Octo memory.We transfer around 5000 x 32 bits in 2ms which is around 10MB/s.I think, it is a bit slow. What is the maximu...
Hi guys,I am using an STM32L552ZET6 and I would like to extend the RAM using an external SRAM chip (23A1024-E/TS), that has an QuadSPI interface. I would like to know if I can use STM32L5 OCTOSPI interface in memory mapped mode with the above mention...
Dear ST community,I was wondering if you could help me with a problem I'm having with an STM32. I have a system containing an STM32F103VET6. The last flash pages are used to store settings/parameters. 2 redundant flash pages are used. This system...
Hi All,In a situation where someone might be flashing an LED using a Timer Output (eg Alternate Function Mode connected to a Timer channel output), what if you want to then turn the LED on solid or totally off and then maybe back to the Timer flashin...
In reading the manuals and datasheets, it seems like it should be possible to simultaneously use all 3 channels (DAC1 Channel 1, DAC1 Channel 2, and DAC2 Channel 1) of the onboard DACs at once, emitting separate values on each. However, no matter wha...
Hello,I am trying to manage data transfer between the 2 core of the STM32H747.My problem is all hardware semaphore are locked just at the initialisation phase ( MASTERID 0X03 , Core M7) After Hal_Init(); & SystemClock_Config(); all is free.after __HA...
Hi,I am considering upgrade from STM32F4 series to STM32F7 or STM32H7(single core) series. However, the H7 embedded memory is not enough for the requirement. I would like to run simple RTOS scheduler. So there is need for external memory.-QuadSPI int...
I'm having an issue configuring the OCTOSPI for accessing an external HyperRAM (Cypress S27KL0643) connected to OCTOSPI1.My basic issue is that the STM32 doesn't provide a chip select or clock when I attempt to access the chip.I'm suspect I'm misconf...
Can i replace the stm32f427vit6 with the f429vit6, f437vit6 or 439vit6 without changing code, and are they completely pin compatible?
