Do you have to enable something else in stm32f?
But when I load code into MCU (STM32F303 on Discovery Board) and feed small signal into the input pin (30mVAC sine on top of 100mVDC) the “output pin” on the MCU is floating, ie not operating like an opamp. Do I have to enable something else? Thanks!
What kind of FPU does stm32g4 have?
The STM32G4 Series combines a 32-bit Arm® Cortex®-M4 core (with FPU and DSP instructions) running at 170 MHz combined with 3 different hardware accelerators: ART Accelerator™, CCM-SRAM routine booster and mathematical accelerators.
Why is the stm32f3 series of microcontrollers important?
A high degree of compatibility with STM32F0 Series guarantees outstanding efficiency when designing derivatives of applications at different performance levels. The STM32F3 Series of mixed-signal microcontrollers consists of:
What kind of ADC does the stm32f3x8 have?
The STM32F373, with 16-bit sigma-delta ADC and 7 built-in gains for high-precision measurements in applications such as biometric sensors or smart metering, The STM32F3x8 line, supporting 1.8 volt operation Package options are LQPF48/64/100, UFBGA100, WLCSP100/66/49, UQFN32 for the devices ranging now from 16 up to 512 Kbytes of Flash memory.
What are the modes of operation of STM32 DAC?
STM32 DAC Channel Modes of Operation Each DAC channel can be configured in Normal mode or Sample and Hold mode. The output buffer can be enabled to allow a high drive capability. Before enabling the output buffer, the voltage offset needs to be calibrated.
Is the output pin on the MCU an opamp?
Then open project in Keil and I can see the OPAMP functions are loaded and compile OK. But when I load code into MCU (STM32F303 on Discovery Board) and feed small signal into the input pin (30mVAC sine on top of 100mVDC) the “output pin” on the MCU is floating, ie not operating like an opamp.
How to generate variable amplitude pseudo-noise in STM32?
In order to generate a variable-amplitude pseudo-noise, an LFSR (linear feedback shift register) is available. DAC noise generation is selected by setting WAVEx [1:0] to 01”. The preloaded value in LFSR is 0xAAA.
