as you said ,u have done assembly programming in 8051 , so u might not have any problem in logic and architecture of microcontroller,. now you simply need to put your logic in c language ,. (there is nothing different so called "embedded c" than regular C language) , just know the syntax , read...

Home made pcb generally get some problem in functioning due to moistures after some time,..and the place where i m designing the things are much humid climate...thats y we are looking for this solution.
SIR , what you have explained is the general theory of arbitration which is based on wire-and logic , the explanation is not in the context of the question i asked which is a special case of arbitration .
kindly refer to my question...
yes ,that is where i was stuck and confused. ,but your explanation arises the question that if master 2 is engaged with another device , then certainly SDA line will be engaged in this , so master 1 definately monitor the SDA line ,and if it engaged (by master 2) then how will master 1 attempt...
while following the data sheet of i2c bus specification (philips 1995) pdf attached
the below lines in bold are not giving me the clear visualization ..
"If a master also incorporates a slave function and it loses arbitration
during the addressing stage, it’s possible that the winning master is...
which micro controller you are using of 8051 ?
and in which language you are coding , assembly or c ?
the moment you place data on sbuf register ,it start sending or receiving, you simply need to monitor RI or TI FLAG to the transmission and reception is completed.
A write to a location in EEPROM triggers an internal programming cycle, which is guaranteed to last no longer than
10 milliseconds.
// on following datasheet of at89s8252 , these lines did not clear its meaning to me.
what does it exactly mean ?
D/A conversion , SC HR-04 , AT89S52
uController - AT89s52
ultrasonic sensor - SC HR-04
DAC sensor - MCP4921 (D/A conversion using SPI)
The complete module was working fine in normal condition.
PROBLEM ARISES when the system is applied in its respected application area.
the sensor is...
