(User can change from one to the other using User push- button) This example also provides signals to connect to the OPAMP inputs: - A sine wave generated by DAC1 (PA4 - pin 41 on connector CN6) - A bias generated by potentiometer RV2 (pin 1 - Jumper JP5) Positive gain ...
B2 RESET: this push-button is connected to NRST, and is used to RESET the STM32 microcontroller. The blue and black plastic hats that are placed on the push-buttons can be removed if necessary, for example, when a shield or an application board is plugged into the top of the Nucleo ...
