Hello,=20 I am trying to use RA4 and RB4 as digital outputs on PIC24F32KA302 to no avail. They look like 3-state or inputs (voltage floating). =20 I have corresponding TRIS bits set to 0, ANSA and ANSB =3D=3D 0.=20 LATA =3D 0x04D3; TRISA =3D 0x0800; ANSA =3D 0x0000; LATB =3D 0xBFBC; TRISB =3D 0x4404; ANSB =3D 0x0000; Secondary oscillator disabled (OSCCONbits.SOSCEN =3D 0;). Other pins (RA0, RA1, RB3, RB5) work as expected, as normal digital outputs. =20 I must be missing something. Can anybody suggest what else to check? =20 help is much appreciated, Thanks, Sergey Dryga --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
