CALIBRATING THE RC OSCILLATOR OF THE ST7FLITE0 MCU USING THE MAINS

3 CONCLUSION

This system allows you to have a power supply for the microcontroller and an auto adjustable

clock set to 1MHz with an accuracy of 1% whatever the external conditions.

This solution also offers the advantage of being less expensive than a solution with a trans-

former and requires less space.

It requires a small amount of space in program memory (less than 90 bytes) in its smallest ver-

sion.
