STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
I am using SW4STM32 (an Eclipse Variant) to code and debug my firmware, which is based on sample codes in package STM32Cube_FW_F4_V1.26.0.I have observed two strange issue:IDE warns me that "Symbol '***' could not be resolved". However, it has no pro...
Hi,i write code in bare metal so every time i initialize a project in STM32CubeIDE i do it as an empty project. I made a project for STM32L011K4 and try to initialize the LPUART, in the startup file i can find that the handler for the LPUART1 name i...
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 successfully initialize W25Q256 nor flash with STM32F746 MCU through Quad SPI protocol. Every command works fine (write memory, write Enable, erase sector, read and write status registers) 1-But when I debug the code and inspect the memory address ...
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...
