how to take microcontroller program output as Log files

Hi all, Hope you all are fine.

I am currently involved in one task in which i need to know each and every operation that a microcontroller does. I though of using UART to print serial stream of characters when a particular event occurs. Using UART is one good method. But i would like to get this information without using any UART kind of stuffs.

For eg. If i send a byte of data to i2c device, i would like to know this information as logs. Does anyone have any idea to collect all this information and save them in a log file?

Hi,

Depends on how much info you want to keep.

A very simple way would be every time you send a byte of data out somewhere, be it I2C or Usart etc, then instruct it to increment a counter for that type of operation.
You could display the info on a lcd for instant feedback

USART OUT 234
I2C OUT 101
I2C IN 219

You can do this only with debugger, I dont know other option for this.

Over UART you will get only data what uC send.

You need define what particular you want to log?

First define "all this information" then we will se what is possible to do.


You can log on SD Card, I2C/SPI EEPROMs, ....



MikroC I²C Library

I2C code example:

void main(){
  ANSEL  = 0;                // Configure AN pins as digital I/O
  ANSELH = 0;
  PORTB = 0;
  TRISB = 0;                 // Configure PORTB as output

  I2C1_Init(100000);         // initialize I2C communication
  I2C1_Start();              // issue I2C start signal
  I2C1_Wr(0xA2);             // send byte via I2C  (device address + W)
  I2C1_Wr(2);                // send byte (address of EEPROM location)
  I2C1_Wr(0xAA);             // send data (data to be written)
  I2C1_Stop();               // issue I2C stop signal

  Delay_100ms();

  I2C1_Start();              // issue I2C start signal
  I2C1_Wr(0xA2);             // send byte via I2C  (device address + W)
  I2C1_Wr(2);                // send byte (data address)
  I2C1_Repeated_Start();     // issue I2C signal repeated start
  I2C1_Wr(0xA3);             // send byte (device address + R)
  PORTB = I2C1_Rd(0u);       // Read the data (NO acknowledge)
  I2C1_Stop();               // issue I2C stop signal
}
