Writing EXTINT register
2004-09-15 by Rodrigo Cesar da Silva Martins
I've tried this piece of code to configure the EINT0 interrupt: PINSEL1 |= 1; // P0.16 as EINT0 EXTMODE=1; // EINT0 edge triggered EXTPOLAR=0;// falling edge EXTINT=1; //clear interrupt flag I'm using a LPC2129, with DKARM 1.3 (uVision + GNU) and ULINK The problem is that EXTMODE was not set, so my interrupt was level triggered. To solve the problem I've written 3 to EXTMODE (set falling edge in EINT1 too). Someone has the same problem? PS:. VPBDIV=0, and I'm not reading nor writing Rodrigo Martins Intermetric Instrumentos Ltda (11) 4761-8009 rodrigo@... [Non-text portions of this message have been removed]
