Bringing clock system configuration from NUCLEO-F207 board to stm32F207 based board

I'm trying to run an application that works fine on the nucleo board environment on a custom board using the same mcu. It's my first time and I'm using a protype pcb version with a very single circuitry. I was working over a firmware example with HAL...

How can I convert an ELF file to DFU file? We use WICED to generate an ELF and BIN file. The conversion tool "DFU File Manager" can convert a BIN file, but when I try to download the DFU file with "ST7 DFU Demo" and "DfuSe Demo" I get "not DFU file"

Transition from PIC

Hello AllNoob question here - seeking advice.I've been using PICs for many years now and writing only in assembler. I've reached the end of my tether with microchip and the lottery of which IDE will work with which programming tool and with which dev...

PWM divider not working

I try to divide pwm like that TIM_InitStruct.TIM_ClockDivision = TIM_CKD_DIV1;it is not working. I am using stm32f030 TIM_TimeBaseInitTypeDef TIM_InitStruct; TIM_OCInitTypeDef TIM_OCInitStruct; // OC: Output Channel RCC_APB2PeriphClockCmd(RCC_APB2Pe...

Why toggling LED4 USER doesn't work with this code ( Board nucleo G071RB) ? I know that problem is in my init function. But I don't know how to correct it because GPIOA base adress (which is also MODER register address) is right

,void GPIO_Init(GPIO_Handle_t *pGPIOHandle) { uint32_t temp = 0; //1.configure mode of gpio pin if(pGPIOHandle->GPIO_PinConfig.GPIO_PinMode<=GPIO_MODE_ANALOG) {     temp = (pGPIOHandle->GPIO_PinConfig.GPIO_PinMode<<(2 *pGPIOHandle->GPIO_PinConf...

STM32H743 I2S DATA MISSING IN THE RIGHT ALIGNMENT

Hello Experts,I am working on i2s of stm32h743. The Manual says when the alignment is left the zeros are sifted from 0 to 7 in case of 24bit data length which is correct work but when I change the alignment right the zero does not appear on 24 to 31b...

Where can I change sampling frequecy of acc sensors in en.fp-sns-allmems2_v2.1.0?

I'm using STEVAL-MKSBOX1V1 for vibration analysis and I want to change sampling frecuency. I did it in the past with other versions of the project but now it has chan a little. I changed the ODR in the file lsm6dsox.c , but I also need to change the ...

Stm32F0 TIM16 PWM not continuous

Pwm is not continuous My clock freq 20mhz Where am i doing wrong ? void PWMparamc(uint32_t PWM_freq, uint8_t duty){   PWMparam.period = (SystemCoreClock / PWM_freq) - 1;   //PWMparam.prescaler = (SystemCoreClock / TimerTickFreq )  ;   temp_duty = ((...

Why there are two pending registers for interrupt? ,e.g EXTI_PR and ISPR

Why there are two pending registers for interrupt? One of them is EXTI_PR and other one is Interrupt Set-pending Registers(ISPR) which is in NVIC controller registers.?What is the diffrence between them?Thanks in advance
