Phase shifted pwm using stm32f103
I am trying to build a current fed push pull DC DC converter. This requires two waveforms with duty cycle greater than 50% and phase difference of 180 dergrees. I would like to know the possible ways of achieving this. I have tried using output toggl...
Resolved! Why the program go to Hard fault without any one instruct of main() run?
I am using the STM32H745 dual core MCU, and the CM7 can be run correctly, but the CM4 go to the Hard fault immediately, I set a breakpoint at the start of main() but can't capture it. Then I set a breakpoint at Reset_Handler in the startup file (st...
Resolved! Getting CAN error Frames due to USB OTG 48MHz HSE clock in custom bootloader
Hi, I have a Nucleo F439ZI board and I am running a custom bootloader and application on it. My Clock config =In Bootloader I am using HSE external crystal (ST-link MCO 8MHz) for all peripheral clock which includes 48MHz clock for USB OTG FS in DFU m...
Default configuration settings contain loop?
I have started a new C++ project and selected my chip (STM32H753II). I changed only the runtime library and left all other settings as default. (See attached.)I then set the release configuration to "active" (see attached) as I do not have the RESET ...
Cycle Time
Hey,im going to use the H743 MCU in ~400MHz core frequency with Free Artos operation system.one of my uses is to sample an analog signal with external ADC in SPI Channel.An interrupt to the MCU will inform “samplenow!�?.im trying to figure how much t...
STM32L412 how can I individually turn off EXTI flags without HAL?
Im using external interrupts on an STM32L412. I want the interrupt to run as fast as possible so I'm not using the HAL to turn off the request, rather I am writing directly to EXTI -> PR1, which needs to be written high to turn off the interrupt, but...
STM32G071 Temperature Sensor stabilization time
HiIn CubeIDE the temperature sensor stabilization time for my STM32G071 is defined by: stm32g0xx_ll_adc.h#define LL_ADC_DELAY_TEMPSENSOR_STAB_US ( 10UL)But in the Datasheet I see at least 15µs max for Tstart(ts_buf) and for Tstart itself its alrea...
interrupt problem
Hi thereI am using a STM32F103C8T6. I defined this pins as External Interrupt:PB4 - GPIO_MODE_IT_RISINGPC13-GPIO_MODE_IT_RISING_FALLINGPC14-GPIO_MODE_IT_RISING_FALLINGPC15-GPIO_MODE_IT_RISING_FALLINGthe problem is that every time I SET/RESET PB4, it ...
