I'm working with a boost converter and have noticed that when resetting the device a PWM pin remains high/floating for a 100-200msI use the HRTIM with complementary inputs and deadtime insertion.If my lowside pin remains floating/high for an extended...
Hi all,I recently purchased a Nucleo-64 board with a STM32F401 and started programming it, while doing so, I accidentally re-configured PA14 & PA13 used for SWD and used by the ST-Link to program the MCU to be GPIO pins. To fix this, I thought of re-...
Hi, I am using the STM32F429ZI microcontroller. I entered primary bootloader mode using the STM32CubeProgrammer option bytes through the ST debugger. My question is: Can I load my LED blinky code (hex file) using the primary bootloader (system bootlo...
Hello, I have a few questions on STM32N6 capabilities for USB after reading AN4879, AN5967 and RM0486 documents: 1. AN4879 states that to be compliant with the USB 2.0 FS electrical spec, the DP+ pin must be pulled high. Does this also hold true for ...
Hi all,I'm trying to adapt stm32loader python script to use it with stm32wl5 chip. So for now it's working i'm able to flash my stm, but for now after flashing Id like to run my firmware.Here is my step procedure : - Put BOOT0 to 1 - RESET mcu - Put ...
Hello. I am working on a project that uses a STM32L496VET6 microcontroller and that can work as an USB device. The board has the following usb circuit schematic:The USB signals are connected directly to the MCU (D+ to PA12, D- to PA11, ID to PA10 and...
Hello! A simple question. If I run DAC, using HAL_ADCEx_MultiModeStart_DMA(..., buffer, ...), when D-cache is disabled, I succeed to send what I filled in the buffer. If I do the same with enabled D-cache, I don't succeed. SCB_InvalidateDCache_by_Add...
Posted on May 23, 2018 at 16:45Hello, I am trying x-nucleo-plc01a1. but there are two jumpers (J5 and J11) on the board. I can't find any document to describe how to use them. Anybody can help?thank you.
Hello ,I have used the below to go into stop mode: HAL_PWR_EnterSTOPMode( PWR_LOWPOWERREGULATOR_ON, PWR_STOPENTRY_WFI ); /* CPU will be halted here until a wakeup event occurs */ in the above function, what is the difference PWR_SLEEPENTRY_WFI & P...
I am using this MCU on a battery-supplied custom board: STM32G0B1RET.I am looking for clarification re. the GPIO availability in Standby Mode.Table 26 in Reference Manual RM0444 (see below) seems to offer one of two (exclusive) possibilities:Without ...
