I think after spending lot of time reading and watching you tube vedios my question is atleast now clear to me... What I want to do exactly is use my Wifi module as a web server.. and displays all the data coming through hardware rx tx , on either pc serial montor or web page..
to do this I...
I hav gone through these examples. I have a question. These examples they use DHT11 sensor with the library DHT11 in their codes. But here I'm not using those type of sensor, I just want to program the module such a way it will grab the data serial trough RX TX pins and send them all to...
Thank you so much for all of your responses
at the moment I don't want to program esp wifi module as the main processor, I just want to grab the digital out put through rx tx pins and send them to a web page like thingspeaks to display them. Do I have to program both the module and atmega328...
Hi,
I need to transmit some which data grabs trough a atmega micro controller to a my pc through the wifi module ESP8266 01 , can I just connect the wifi module to get these data or should I pre program this module in order to send the data to pc? I'm not sure what to do exactly,
any help...
Hi,
Im designing a LNA using ADS.
I have designed my single stub matching network and I use short circuit stubs in my design. I am getting a negative gain and I m confused about this.
If anyone can help on this it will be a great help.
Can anybody explain what is the difference between BSS138 N-Channel Logic Level Enhancement Mode Field Effect Transistor and the 2N7000 / 2N7002 / NDS7002A N-Channel Enhancement Mode Field Effect Transistor? and the various applications
It has a rs232 communication method but the output is not in the rs232 voltage range. It has the output voltage range of ttl. but the problem was it out put 2.85 max voltage out and swings between 0 -2.85V. This was not enough to trigger the rx pin of pic. that's why the need of buffer circuit...
Thank you for replying, I could set the baud rate to 4800 bps in my coding, now the problem is when i connected the module with micro controller it won't display anything on the LCD screen
But i could do my task by sending same NMEA sentece via my computer serial port to the mcu.
I can't...
thank you all for supporting me. Yes it is the problem with frequencies. oscillator frequency didn't match with the programmed frequency. I corrected the errors in my circuit. Now its functioning well

Hi , I want to interface LCD module with PIC 16f877a
I used the following code and used Hitech C
my main program is,
#include <htc.h>
#include "lcd.h"
void
main(void)
{
lcd_init();
lcd_goto(0); // select first line
lcd_puts("12345678");
lcd_goto(0x40); // Select second line...
