Witryna19 cze 2024 · I'm trying to amplify my input signals with internal OPAMPs on STM32G4 mcu, also i need to control bias because signals are shifted. Bias levels are adjusted with DAC. As long as my mcu has only 3 DAC pin-outputs, but 5 of 6 OPAMPS have internal connection to DAC outputs, I try to pass bias level internally. 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. chillula bandWitryna11 lut 2024 · The new members of the STM32G4 Access Line offer increased memory capacity with 112 KB of RAM and up to 512 KB of Flash, compared to the 32 KB of RAM and 128 KB of Flash of the STM32G431, the flagship of the Access Line until now.
