Hi,
I'm working on LPC2148 controller, and with the example code, user manual
reference getting the constant frequency of 500mHz[square wave], but I need to vary the
frequency from 10hz to 12hz with the particular time duration set and stop the PWM
pulses.
Now i'm getting the PWM output at...
Hello all,
I'm using LPC1115 controller and getting PWM signal at PIO1_9
by varying prescaler register and keeping the values constant of MR3,
so I had set a time and pulses generated continuously and stopped within that time,
and for this I used a delay loop within this loop the pulses...
Hello!!
I need to interface LPC115 controller through I2C for a touch sensor[keys],
For that sensor to work I can use an ATMEL controller.
But before going to this I just want to interface I2C with an led.
So kindly suggest me on how to proceed.
Thank you.
hI!!!!!
I'm using lpc1115 cortex-M0 processor, I have started working on it,
I need to use capacitive touch screen(i.e, capsense) instead of tap keys,
so please can anyone help me out with the block diagram, an breif explanation
on how to work on it, i'm using Blueboard Lpc1115 and coocox...
As i'm using Keil IDE, i'm getting the warning as too few actual parameters,& is there any alternative for uint8_t since in my program i have not used
stdint.h header file so when i initialised uint8_t to unsigned char typedef it got compiled with the above warning msg..
Help me in solving this...
Yes i'm using keil version4...

I tried to upload the uvproj file but it is showimg error message as invalid file...how to proceed now...is there any alternative method to complete this:-(
You using R2R ladder for P2.0 to P2.3? i.e., 4 bit digital to Analog conversion?
I just tried what you told but i'm getting error near DAC_table as syntax error,although i checked it by assigning int and char...and particular version of the language standard is not supported by the...
Hi,
I'm working on 89v51 microcontroller, the thing is i have to initialize four ports[say P2.0,P2.1,P2.2,P2.3] and assign binary values 0000 TO 1111 to each port[i.e hex no's from 0 to F]say P2.0=0;P2.1=0;P2.2=0;P2.2=1 and it goes on till last binary value, and there are two keys for the...
I could not post my complete code here...hope this might help me..
I tried to attach the file but getting invalid file name...below is the main.c code....i have left the comment lines as it is...[since i had tried but didn't worked]
void fnSelectVoltage(void)
{
//int V1,V2,V3,V4;
//V1 = 7;
//V2...
Hi all,
Can anybody tell me how to assign values to the individual ports,[0to15 hex decimal values to ports] i mean to say i have taken port2 as my reference
in this i have to assign P2.0=0 ; P2.2 = 0 ; P2.4=0 ; P2.6=1; this is first set value i.e.,0001 means it should display 7v,
similarly 0010...
Hi,
Thanks for the information,it was really helpful.
Can you give me some hint that how this values can be stored in the program,as i'm using C code,
and for this i'm using if_else statements, it should be programmed in such a way that when we press
some button it should vary[i.e, voltages...
Hi all!!
How to assign the voltages[say 7 to 12v] using hexadecimal values,since i'm using pic microcontroller i have already assigned 4 ports as v1,v2,v3 & v4
and initialized different hex values to these port numbers,so when we press any key it should set to the particular voltages.
Kindly...
How to start with this microcontroller[LPC12XX] using keil software,actually was using P89V51RD2 microcontroller now migrating to this LPC chip,
so please explain how to go ahead....:roll:wink:
