hi friends,
i am using cypress cpld with part no: cy37256p160-125axi.
when power is switched ON in Tri-state condition, the cpld I/O lines has spike V(peak to peak)=1.63 V and T=1.7m sec.
i have try to search in the data sheet for this issue. i couldn't find any information.
please help me out...
hi friends,
i am new to jennic software.
i have tried to compile default api's
i have seen few errors shown in "error.bmp" file
please help me out
thank you
hi friends,
I have trying to learn EN87C196KC20 INTEL MICRO CONTROLLER
I could not get compiler for it.
If any one knows about it
please help me out
thank you
Re: doubt in LPC2129
thank you for reply.
but PCLK=60M Hz, then T=16n sec.
it means 1Machine cycle <------>16n sec,when VPBDIV=0x01;
if VPBDIV=0x02; then PCLK=30M Hz ----T=8n sec
=> 1Machine cycle <----->8n sec.
is that true?
please help me
thank you

hi,
you cannot increase the IO pins for 8051 .
but your can use the 8051 micro-controller IO pins efficiently by using a decoder (or) by using few protocols like I2C,CAN, .. and so on.
it is only option
hi friends,
i am new to arm7 LPC 2129.
it is a 32-bit micro controller.
where as in 8051,
1 machine cycle is executed in 1 micro second.
so my doubt is
what is the time does ARM 7 takes to execute 1 machine cycle?
if i want to write delay program with out timers in LPC 2129.
so, how many...
hi friend,
thank you for the reply.
LCD display square boxes only.
even i tried to reduce PCLK to 10M Hz.
because LCD runs at Lesser frequency and where as ARM 7 runs at higher frequency.
please help me out with this issue.
hi,
i am new to ARM .
i have t o interface to LCD with LPC2129.
i have written the code. LCD is not displaying.
#include<lpc21xx.h>
unsigned int rs=0x00000010;
unsigned int rw=0x00000020;
unsigned int e=0x00000040;
void MSDelay(unsigned int itime) //delay function
{...
hi friends,
i am new to ARM micro-controller.i need to write ADC code for data logger unit.
so, i am working on it .the data from ADC( ADC0 and ADC1) is not been displayed on hyper terminal .controller is been waited for forever ( AD0DR1, last bit to be set as '1' =31 bit).

hi friends,
I am trying to interface PT100 to microcontroller which has 10 bit adc.
i have tried with voltage divider circuit with PT100.
it is not working out .
i am sending circuit diagram also which i have used .its giving an error of 4 deg variation.
so please help me out with circuit...
hi friend,
thank for the reply
but according to i2c protocol.
master transmitter should not send ACK to slave receiver during transmitting data.
please help me out .
thank you once again
