Hey!I'm trying to create a driver for the STM32U545 for TinyUSB . Currently, theres a driver existing for device mode, and theres driver for the boards using synopsys and not usb_fsdev. I have followed the reference manual, and gotten so far:hcd_stm3...
I am currently working on a project that uses the STM32U575CGU3 microcontroller. The goal of the project is to display pressure and temperature values over CAN J1939 and CANopen communication protocols in a digital output format.For sensor data acqui...
I am trying to use the DA function of the STM32H573. I can successfully write the OBK file (with TrustZone disabled) and regression via STM32_Programmer_CLI.exe. However, I encountered an issue when trying to read the plaintext of the OBK payload in ...
Affected doc / sectionRM0492 (STM32H503) → General-purpose timers → Master mode selection (MMS) (TIMx_CR2.MMS = 0000 “Reset”)Current wording (verbatim)“MMS = 0000 – Reset: the UG bit from the TIMx_EGR register is used as trigger output (tim_trgo). If...
why need to monitor txe flag and btf flag to transfer data after each byte.txe says data register is empty,btf and txe says need monitor after last byte. according to reference manual.but my question is how should i know i get ack after sending 1 by...
I’m implementing an audio clock source switching mechanism where the system runs on the internal audio clock if no external clock is detected. As soon as an external clock becomes available, it switches to use that external clock source.This works in...
Hello ,I am working with comparators on the STM32L496VGT6 microcontroller.In my setup:COMP1 is configured for rising-edge detection.COMP2 is configured for falling-edge detection, forming a window comparator arrangement.One input of COMP1 is connect...
Hello, I have an STM32L4R5 MCU on a custom PCB and I have flashed it with my firmware via USB_OTG_FS. Both CubeProgrammer and the CubeIDE have worked in flashing the MCU for me, given I have an ST-LINK connected to it as well. I have USB_DM, VBUS_Se...
Hi,I want to use LPTIMx to output a PWM signal that changes duty cycle on each period with DMA. The HAL driver implementation for LPTIM PWM is completely wrong, so I tried to find out how to do this from TRM etc.LPTIMx has 3 DMA request events:2xCCRx...
Above is the configuration of my Timer. - To generate pulse, first I used HAL_TIM_OnePulse_Start but with that pulse was not generate.- So I did this: while(1) { HAL_TIM_PWM_Stop(&htim17, TIM_CHANNEL_1); __HAL_TIM_SET_COUNTER(&htim17, 0); HA...
