Hola buenas estoy realizando un proyecto de un exoesqueleto de mano con un sensor de EMG,
estoy utilizando el sensor EMG de DFRobot SENS0240 y una placa ESP32MINI al subir el codigo a la ESP me da este fallo;
(invalid conversion from 'int' to 'SAMPLE_FREQUENCY' [-fpermissive])
con Arduino funciona perfectamente pero con ESP no se por que no compila.
El codigo que estoy utilizando es el de la propia pagina y la libreria es EMGFilters.h.
Muchas Gracias. Un saludo
