Hi,
I am working for sending and receiving SMS from SIM900A to PIC16F877A. I have usd isr to receive the response from SIM900A. It seems that the firmware goes into isr when the character is received but I am not able to fully store the received message in an array. I am pasting the ISR and...
Hi all,
I am trying to interface my MSP430F5419A with M95-M02 (SPI based external EEPROM from ST micro). I don't have much experience in SPI. I have just followed few links on the web and trying to read and write the data. But I want to know the flow of code for this SPI IC first. I have...
Hi,
It would be good for you to divide your work in modules. LM 35 is analog sensor, it will give output in volts which is very low. So you need to amplify voltage before feeding it to microcontroller. Develop other modules from PIC controller side, like Buzzer, led on-off, timer and ADC...
Hello all,
I am working on a project, which needs simulation of speed control of 3 phase induction motor using the direct torque control method. I have seen several ready models in MATLAB but i want to make a newer one by myself. But i am not getting things done. I made a VSI and a little part...
Re: lpc2148
I was using keil uvision3 for the programs. You should need to make some changes in the code according to your requirements. As i said before these are demo programs but cannot work directly. make some changes in code.

But sir,
It doesn't get run as you can see in my first post. I blinked three pins of Port C on successful write and read of single byte.
which doesn't happen.. when I read it, it gives 0xff..
Can you tell me where i made mistake in my code ?
or any fuse bit problems ?
Is it necessary to...
Hi,
Yes, I heard about that.. It's something called HI Tech eeprom qualifier.. But i don't know how to use it and if my current version is supporting it or not ? If any one knows that way to write in EEPROM, it will also be helpful to me.. I have evaluation version of Hi tech PRO 9.60PL5...
I have already configuration bits like this.
I am using 16MHz crystal so I already use HS oscillator, Watchdog timer off, Low voltage programming off..
Still I am writing the same in code now and testing again, I have set those in configuration bits...
Thank you and please tell me if any other...
Hey,
No one to reply..!!!!
My read function works ok and reads 0xff on every location but when i try to call write function, the WREER bit gets high and the write operation gets interrupted...
Atleast answer me now, I am stopped...

Hello,
I am trying to save some bytes of data into the internal EEPROM of PIC16F876A, but i am not getting the things done. I am using Hi- Tech C compiler and it has example code for EEPROM in pic.h.. I am using that, i write single byte in EEPROM and read the same and compares it but i am not...
Hello,
I am new to PIC32. I was previously using PIC16F877A for my work but in this new project i am working on PIC32MX65F256H. I have seen datasheet and also the manual for PIC32 Microcontrollers but not able to understand all. I have achieved USART in 8 bit PIC but i am not able to run the...
Hi,
Had you checked your hardware? if it's ok then simulate your code in keil check whether particular port pin blinks or not. Also check the delay by single step debugging, you will get to know that how long is your delay loop is..

Re: Help: Problems on interfacing PIC18F252 with GSM Modem.
Hi,
In your code when you need to give enter, you have given 0x0d.. Try with 0x0a and then 0x0d. For example, call a function like given below to give enter to every commands..
void ENTER()
{
uart_putc(0x0A);
uart_putc(0x0D);
}
