Target LPC2124 I am Using TPS3836k33DBVT reset IC. at 200ms delay time. It doesnt reset at all. But when i use RC circuit with diode it works atleast sometime. What may be the problem?
I did following to get Square wave form at P0.21 of LPC2124 PWMPR =0; PWMPCR = 0; //SINGLE EDGE PWMMCR= 0X0002; // TC reset when match MR0 PWMMR0=100; PWMMR5=50; PWMLER=0X21; //MR0 &MR5 will be effective PWMTCR= 0X02; // reset TC & RC PWMTCR= 0x09; //counter & PWM enable PWM module ON & p0.21 selected for PWM5 o/p I cant see any wave form on P0.21 after down loading Can any one locate the prob.
Hi may be you have to configure the PINSELx before using PWM. I'm offline to the specs but for sure without activating over PINSELx you have just GPIO at the PWM pins. Only ADC is invoked by default. Günter
Hi Günter thanks I did these settings. But i found the problem now I need this statement to enable PWM5 PWMPCR |=0x2000;//PWMENA5 enabled. Now it works fine Thanks.
Hi Any one developing IrDA interface with LPC2124 or LPC313x; I am using MCP2155(from mhip) and connect to UART1 of LPC2124. Do any one have interfacing program for MCP2155. Or did any have similor experience regards k.muraletharan
