This example shows how to update at regulate period the WWDG counter using theEarly Wakeup interrupt (EWI).
The WWDG timeout is set to 262ms, refresh window set to 41h and the EWI isenabled. When the WWDG counter reaches 40h the EWI is generated and in the WWDGISR the counter is refreshed to prevent ...
Accurate measurement of the third order intercept pointfor low distortion IC products such as the LT5514 requirescertain precautions to be observed in the test setup andtesting procedure. The LT5514 linearity performance ishigh enough to push the test equipment and test set-up totheir lim ...
ATmega8 taillight circuitAn assembly language program that generates 5 different static patterns with switching from pattern-to-pattern controlled by the depression of one push-button switch (S2).
ATmega8 taillight circuitA more complex C program that implements different flashing patterns under the control of both the push buttons and potentiometer. Use your imagination to come up with some novel ideas here. Remember however that more marks are to be awarded for the quality of the code than ...
