Master:Platform: stm32G070cbQuesion:The MCU pin is driven through a 100R resistor to drive an N-channel MOS transistor (2N7002, Ciss < 50pF).When the pin is given a high output, the starting transient current peak approximates I = 3.3V / 100R = 33mA,...
I'm having difficulty writing to STGAP1BS configuration registers. I'm using a Nucleo -G474RE to communicate with STGAP1BS chip on a custom board through SPI bus. Below I'm trying to configure CFG2 with the value 0xA0 but when I read back the registe...
I should choose a microprocessorcontroller (to be implemented on a pcb in the future) to control a 3-phase brushless motor using field oriented control.There are really a lot of MCU models, so I would like a guide/advice that shows how to choose it a...
I have a project with its ioc, the setup of the peripherals are ok.Now I want to edit a file while cubeide is closed and have the change reloaded when I reopen the ioc.Let say that I set the baudrate of UART5 to 115200: in some file I'll have the UAR...
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...
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...
