For a project, I could grab a few STM32L4R5ZI-P µC and am not sure what to connect to the 2 SMPS VDD12 pins when I do not want to provide external voltage but use the integrated LDO.The datasheet is not quite clear on this scenario.I have no augmente...
Hello all,In a custom board I wrote a very simple code using stm32cube.When I start debugging it shows this message"Break at address "0x1fff1d66" with no debug information available, or outside of program code."After that I see the cursor in main at ...
I want to add some new annotations to this stm32f429xx.h to help me understand, but VSCode tells me that I cannot "write to files", so what should I do to make vscode write successfully？
I am using STM32H7 General Purpose Timers TIM2, TIM3, TIM4, TIM5 and their respective external trigger ETR using combined RESET and TRIGGER modes and I am configuring and starting Channel4 for each to generate One-Pulse output . All the configuration...
I don't fully understand one thing with STM32L552 which has no SMPS: Does decreasing the VDD from 3.3V to say 1.8V reduce it's power consumption?All the measurements in datasheet and in AN5213 are done for operation ranges and in SMPS modes I see tha...
I am developping a driver for a QSPI memory mapped memory on STM32H753.In SPI mode it works fine.When I switch to "quad io" mode (ie. 4 data signals) I read corrupted data. Adding some delays between reads improve the results (but doesn't completely ...
Hello,I use STM32F091VC the from 4 year without problem, I have used more than 20000 STM32F091VC. Recently, I have several STM32F091VC who have a big problem of accuracy on the clock HSI. The error is about 30% ! For exemple, the STM32F091VC give abo...
I have a Cypress S25FL064 flash memory connected through QSPI interface to a STM32H753.The memory is booting in "single IO" mode (ie. classical SPI protocol with MISO/MOSI signals).In this mode I am able to erase, program and read the memory through ...
