Hi all Embedded Genius!
I have downloaded STK500V2 bootloader from below link.
Link : https://github.com/joede/stk500v2-bootloader
I have changed makefile as per requirement as below.
MCU : atmega2560
BOOTLOADER_ADDRESS = 0x3F800 (as bootloader program is 1954 byte so selected bootloader...
Hi Geeks!
I am working on Linear Actuator which i made from Stepper motor with screw mechanism.I am using it to push the metal object.But i am wondering how can i come to know at when exact the linear actuator comes in contact with metal object so i can calculate the further linear push.I need...
Hi!
HC05 bluetooth module communicate with atmega using USART.
so Just need to learn USART communication with proper Register Value calculation.

in your code UART intialisation use ubrr value is 6. USE 51 for 9600 baud rate
Try it.
Thanks Altaero for your contribution to this post.
I have redefined all the variables in my project.
You might be right about issue of pow function & FPU.
I got the simple solution.
Actually HEX value is a temperature value in my project which after conversion to decimal i have to divide by...
Thanks to all for reply.
I am able to convert 1 digit HEX to Decimal successfully.
As digit increases the final decimal result comes with -1 error.
for two digit HEX (00ff), i am getting 254 which is actual 255.
for three digit HEX (0fff), i am getting 4093 which is actual 4095.
In the first...
Hi Geeks!!
I am working on project with Atmega8 and want to communicate with another MCU using USART.
I am able to communicate with USART at 19200 Baud rate at 8MHz frequency.
But i am getting values from another MCU in HEXADECIMAL.
I have written Code to convert hex to decimal.I am closer,But...
Hi!
I found this documentation for PID.
www.atmel.com/dyn/resources/prod_documents/AVR221.zip
I have written code as below.
I am reading measured temperature as double value
#include..
..
...
..
uint16_t adc = 0;
uint16_t adchisto = 0;
int main(void) {
char printbuff[100];
char...
Thank you all for quick reply.
@Fvm : thanx for filter suggestion.
@warpspeed: you mean i have to set different initial gain for cooling and heating process so i can reach the desired temperature?
I got below link for PID program in C.

Hi Electronics Geeks!
I am working on TEC temperature controller using ATmega32 MCU. Thermistor of 10K is interfaced and the Steinhart-Hart Thermistor Equation is applied to get the temperature reading using ADC.I am getting correct reading with little Fluctuations.The other part of the project...
Hi frds!

Hi!
I am going to develop RFID system which can read tag and update data to server.
I am looking for reader which can read passive tag even if it is in pocket/bag or in box.
What parameter/factor i have to see to find such type of antenna of UHF reader?
I have read about linear and circular...
HII!!
I am working on project in which i require the person identification from 1-2 meter and that id need to be sent to web-server through gprs(GSM module)with gps location.I am having good knowledge of Atmel AVR(ATMEGA32) series MCU.But i am facing several issues..Please help me.
