Hi,I am able to read the mcu temperature but I want to know the maximum worst-case time required to read the internal temperature of stm32h743.The clock for the ADC is configured as 76 MHZ. Does that mean that 1 ADC cycle is 0.013 uS (1/76M) ?#defin...

Thank you @waclawek.jan for your reply. I see that it is happening even without the debugger connected. so it is not due the debugger.I will try with a minimal project and let you know.In the meantime, can you think of any corner case scenarios when...

Hi @waclawek.jan ,Thank you for your reply.Hmm..I see your point and I understand why I am seeing this during debugging.But should this issue happen if the debugger is just connected and the ADC3 registers (including ADC_DR)are not opened/viewed ? No...

Hi @waclawek.jan , Thank you for your reply.Yes, The error code returned is 0x03 which is HAL_TIMEOUT.This is returned from the point marked below and the value of ISR and ADC3_CSR is same which is 0x1003.This means that the EOC flag is not set.Can I...

Thank you @waclawek.jan for your detailed reply.So, I am using a prescaler setting of ADC_CLOCK_ASYNC_DIV2, a resolution of ADC_RESOLUTION_16B, and a sampling time of ADC_SAMPLETIME_387CYCLES_5. I calculated that the maximum time for a single conver...
