ciao
stò cercando di utilizzare una scheda per un sensore capacitivo della sparkfun
https://www.sparkfun.com/products/9695

ho compilato il codice fornito dal link e ottengo su questa riga
Code: [Select]
uint16_t touched=((MSB 8) | LSB); //16bits that make up the touch states
questo errore
Code: [Select]
mpr121.cpp: In function 'void readTouchInputs()':
mpr121:85: error: expected `)' before numeric constant
mpr121:85: error: expected `)' before ';' token
mpr121:90: error: invalid operands of types 'uint16_t' and 'int __complex__' to binary 'operator&'


non conosco il linguaggio al punto di capire cosa significa, qualche aiuto

grazie

non trovo l' esempio che hai usato
Mi dai il link preciso?
Ciao Uwe

ciao
risolto, si trattava di errori di sintassi ho trovato una versione di codice uguale e li ho confrontati

grazie
