Increasing prescaler on the fly causes the timer to never update.
I am using an STM32L496ZG-P to create PWM signals for a switching power supply, and I need to precisely vary the frequency linearly over the course of a shot. My clock speed is 80MHz and I need 20ms long PWM pulses in the 10-20kHz range. To start, I ...
Resolved! STM32H755 HTRIM PIN high after POR
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...
Bootloader over UART with Nucleo-64 Board(MB1136) - No response?
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-...
primary bootloader
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...
Resolved! STM32N6 USB device implementation questions
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 ...
Send go command to usart bootloader
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 ...
Resolved! STM32L496 not raising interruption on USB connection
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...
Resolved! DAC in DMA mode @ enabled cache
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...
