Hi there,I have got an STM32H7B0 processor.I would like to make a part of the AXI (main RAM of application) not cacheable so I don't need SCB_CleanDCache() before/after DMA write/read transaction.But another part of the AXI RAM should be cacheable an...
I'd like to use one of the watchdogs on STM32F407, but I'm surprised the maximum timeout of the WWDG is so short (around 50millisecs, depending on clock speed).This is very restrictive, for example a sector erase takes much longer than this (and is a...
I am having trouble using the DMA with SDADC. The samples are coming in ok but their sequence in the buffer drifts through it. Anyone can help? i.e. every channel is open to the air except for one input i have a voltage applied. This value you can cl...
I have no idea why this code is not working. I am sending chunks of a file with UART followed by short instructions of 2 bytes to tell the MCU whether another chunk is coming or to start playing the file.The MCU receives the first chunk without an is...
I am working on a portion of code that handles some UART messages that come in periodically from an LCD. The reception of a message over UART from this screen will generate a response based on the parsing of the message received.It is part of a large...
Another day, another bug....I'm trying to use ADC3 with BDMA on H753. Started from some cube-generated code that assigned BDMA channel 0 to ADC3.Allocated memory in SRAM4. Added interrupt handler for BDMA_Channel0 and ADC3.When I start the ADC3, I hi...
Hello, I'm quite new to STM32 (although I've been looking at it for more than a year) and I'd like to use it for a project that has been going on for somthing like 2 years now. It's a digital audio mixer especially designed for portable use for movie...
Hi,if I never call any wfi / wfe and run my stm32l0xx mcu in permanent run mode, I got a sawtooth shaped consumption current. In normal mode, where I call wfi, this is not a issue, but I'm curious.Any ideas where this comes from?Thanks & best regards...
