Hello,I try to use the FPU exception interrupt handler in STM32H743ZIT but the FPU interrupt is not coming. I initialized the interrupt in this way:HAL_NVIC_SetPriority(FPU_IRQn, 0, 0); HAL_NVIC_EnableIRQ(FPU_IRQn);Than provoke a division by zero FPU...

The function using ADC_CALIBRATION_TIMEOUT. This timeout is defines as:/* Fixed timeout value for ADC calibration. */ /* Values defined to be higher than worst cases: low clock frequency, */ /* maximum presca...

Hello I have a custom board with a STM32H753ZIT and I’m wondering about the amplitude of the HSE crystal. It is only 300mV (see the attached Image). It seems to wok but is this normal?The crystal requires a load capacity of 20pF per datasheet, the ca...

When for ADC2 Channel 18 is selected as Injected Channel and initialized via “HAL_ADCEx_InjectedConfigChannel�? it will return HAL_ERROR.When no other ADC it will fail in line 2288 2286*. When another ADC is enabled it will fail in line 2277 2275*.HA...

Posted on May 23, 2018 at 11:32Hello, I�m struggling understanding the I/O static characteristics for the STM32H7 devices.I think that below 0.3xVdd a normal input is low and above 0.7xVdd it is high. But what is the meaning of the red marked lines?...
