ATMEGA32 Examples

These examples are designed to demonstrate how to use a ATMEGA32 to communicate with our modules. All the modules which use the I2C bus have pull-up resistors to 5v. You only need one set of resistors for the whole I2C bus regardless of however many I2C devices you have connected to it. You can find more information about the I2C bus in our I2C tutorial.

CMPS03
This is an example of how to use the ATMEGA32 to read the bearing from one of our CMPS03 modules using the I2C bus, then display the bearing data to an LCD03.

CMPS12/11
This example reads the bearing from our CMPS11 in I2C mode displaying the bearing, pitch and roll on an LCD05.

SRF01 Ultrasonic Ranger
The SRF01 uses a single pin for both serial input and output, a BAT85 diode stops the SRF01 from driving the output line of the ATMEGA32 when returning data  The Range is displayed on an LCD03 module.

SRF02, SRF08, SRF10, SRF235 Ultrasonic Rangers
This example communicates with the SRF02, SRF08, SRF10 or the SRF235 using the I2C bus. The SRF02, SRF08, SRF10 and SRF235 all use the same I2C interface. The basic ranging commands are the same, so this example works for all these rangers.

SRF04/ SRF05 Ultrasonic Rangers
As the SRF04 and SRF05 use the same method of communicating this example is compatible with both the SRF04 and SRF05.

TPA81 Thermal Sensor
The TPA81 connects to the ATMEGA32 using the I2C bus. This example displays the ambient temperature and 8 temperatures from thermal sensor on an LCD03 aswell as driving the TPA81 servo.

MD03 24V 20A Motor Driver
This example runs the motor forwards and backwards using the acceleration register to move the motor to a set speed.

MD22 24V 5A Motor Driver
This example runs the motors using the turn register to alter their speeds.

MD25 RD02 Motor Controller
This example comunicates with the MD25 via serial and drives the motors displaying the encoder values on an LCD03 in hex format, as well as the motor currents.

RLY08 Relay Module
In this example used the I2C bus to control the RLY08 turning the relays on and off individually.

SD21 Servo driver
The example moves a servo between 2 positions. 

SD20 Servo driver
This example uses the ATMEGA32 to move the first servo on the SD20 between two positions.
