I'm using the STM32L431xx mcu. The current hardware configuration of our design has no external clock source (crystal), so we are using the internal one. And there's a new functionality which demands second-accurate real time clock, over a period of...
Has anyone have similiar issues ? I got I2C DMA writes working nicely on table, but in real application there are disturbances which cause false start condition on the bus.This happen when I2C HAL driver has "lock" on I2C handle - so incoming interr...
Hi,please find the attached register values of WWDG register on Reset positionRegards,Sudheer
I'm trying to count the number transition during the time another process is taking place. Don't need frequency, just the counts.So I've enabled TIM8CH3 for capture-compare, and have verified that CCR3 does change when there are transitions on th...
I was looking at the ARM M7 reference manual, and it shows an empty NVIC ISR vector from 0x40 to 0x3fc. When I look at the file startup_stm32h725xx.s it defines specific interrupts mapped to the ISR vector. Are these hard mapped by the EXTI block an...
I have the STM32H7B3I-DK (MCU: STM32H7B3LIH6Q), and I am trying to get the sys_ck close to its maximum frequency of 280 MHz, by running HSI or HSE through PLL. The trouble is that I can only get up to 164 MHz. Any higher and I get a hard fault. Is th...
So I am trying to send an ADC value that I receiving on the board over I2C to another device. I have adc_Value as a 32 bit one since the ADC read function on HAL is 32 bits. I want to send this over i2c. Currently I have this. HAL_ADC_Start(&hadc1);...
I am using 115200 bits/s for now and was wondering if I can increase that. If yes, how much can I go until? I checked the datasheet for this board and nothing was mentioned about the baud rate.
I have been trying to start PWM on TIM1 with complementary channels and use DMA to start the PWM. The problem that I have is that only one of the channels will start when I run the program. DMA channel 2 is being used by TIM1_CH1 and I can't find any...
