I have a problem regarding VDDA on my hardware piece, that has an STM32U535RET6 chipset. According to the documentation, this exact chipset, does not have an internal reference buffer, so I'm stuck to using the VDDA/VREFINT as they are for my ADC1-IN...
Hello, i am using STM32H723 Microcontroller. I need to create a region in the memory(preferably whole sector 7) that is not erasable during debugging process. To do this i made the following changes in the linker script:MEMORY { ITCMRAM (xrw) : ...
Hi We want to use STM32U575 Watchdog Mechanism in our operational FW, but have the following concerns:1. Can MCU ST Bootloader kick the WD in general, and especially duringca FW update, when it is busy writing/reading to flash the new FW to update or...
Currently i am writing my own MCAL drivers for G4 MCU's and i dont understand interrupts for timer channels 5&6. Lets assume Timer 1 where you can check interrupt status of CC of channels 5&6 in TIMx_SR on bits 16&17. But there is no mention about ac...
... leads to "funny" results:STM32L011 with 16 kB of flash, HAL inits and LED toggle in main, DEBUG, no optimization:93% of flash usedI had not expected it to be that bad! :grinning_face_with_sweat:Okay, I will probably not use too much HAL, will use...
Hello,I'm refering to DS14121 Rev 1 of STM32H573xx. - "Figure 1. STM32H573xx block diagram" shows 4 32 bit timers (TIM2, TIM3, TIM4, TIM5)- "Table 2. STM32H573xx features and peripheral counts" says there are only two.Where can I find trustworthy inf...
Hi everybody I'm developing a simple bootloader which run an application loaded in flash memory at the address 0x80200000. The application alone works correctly but when I use the boot the app doesn't run. This is the code of my boootloader #defi...
Hi. I am building USB PD sink device. I would like to use built in STM32 UCPD controller.I've created test application in STM32CUBE based on AN5418. It works properly but i want to add PDO read functiinality.All tutorials say that all info about port...
Hi， I'm using STM32G431 to drive my SPI screen. Due to the high cpu load, i decided to change the IT sending mode to DMA. After putting a little changes on code, it doesn't work any more, and i have confirmed it will work again once get it back to IT...
Hi,Master:platform: STM32G070CBphenomenon:When the MCU is empty (without any program), connect an external pull-up resistor 10K to the adjustable voltage source on the PA4 pin, adjust the voltage in the range of 4~18V, and find that the maximum clamp...
