Project description
The services of a software developer are required. Develop a C program in Atmel Studio 7.0 for the AVR ATmega8 microcontroller. "Peace-level capacitive sensor."
The following changes should be made (reworked, possibly re-developed) to the existing framework;
1. As a display device, use the 10 segment LED indicator Grove LED Bar on the MY9221 chip connected to the controller via the I2C interface.
2. Charging should be done with one button (held when power is turned on) for:
"empty tank"
“6-8 intermediate values”
"full tank"
3. Provide a RESET button that erases the calibration values for recalibration.
4. Test the circuit in Proteus 8. With different frequency setting values from the external timer on the NE555.
In the range of 10...40 pF. The actual capacity is not yet known.
The code is accompanied by detailed comments.
