Witryna5 lip 2024 · STM32G4: up to 170 Mhz Cortex M4 => ISR enter latency 70 ns These calculation do not solve your problem though, because we have to consider as well what happens after the MCU entered the service routine. Several things come to my mind here: Backup of additional registers depending on the complexity of the ISR
WitrynaTconv = Sampling time + 12.5 cycles. Example: With an ADCCLK = 14 MHz and a sampling time of 1.5 cycles: Tconv = 1.5 + 12.5 = 14 cycles = 1 µs. The ADC Sampling Rate (Frequency) is calculated using this formula: SamplingRate = 1 / Tconv. For The Previous example where Tconv = 1µs, The samplingRate = 1000000 = 1Ms/sec. chuck taylor high tops saleWitryna10 paź 2024 · Actually it is calculating Vdda, since the Vref calculation is very simple, you have to read the corresponding channel of the ADC with a sample time longer than … despicable me 2 training wheelsWitrynaSTM32G4: First ADC samples are not correct Summary: I am sampling the internal voltage reference 5 times using DMA with the ADC set to continuous mode with … chuck taylor high top shoesWitrynaSTM32G4: First ADC samples are not correct Summary: I am sampling the internal voltage reference 5 times using DMA with the ADC set to continuous mode with LL_DMA_LIMITED.
