    A switch which is used to control the lcd-back light. Attention! This feature requires a hardware extension.. The mode selection is used to assign a specific function to any input stick. At the end it changes the labels which are shown in all other menus where input values are selected.

    Function 4.1 Power on sequence During power on sequence some important tests are executed. First the EEPROM data is loaded and verified. In case of fault a warning is given and the whole EEPROM is formatted. After this it is checked if free memory is enough to store at least one additional model memory.

It is guaranteed that the center position of the sticks leads to the value 0. Potentiometer-values are handled according to this.
  • Page 23 y = f(x) = x^k with 1<=k<=3 This diagram shows both curves, the polynomial and the original expo-function in a blue colored line. The lines in red show the derivation of the blue line. Therefore you can recognize the sensitivity of the stick at several working positions.. The polynomial was used in the implementation because we can evaluate it without usage of any floating point arithmetic's.

    4 Function 4.2.3 Trim This block adds the current trim-value to the associated input value.. This trim value is generated by pressing the trim-keys. The range of this trim -value is -31 to +31. This value is directly shown in the graphical representation in the main screen.

    4.2.6 Limits Before this output values are sent to the receiver, they are checked against the max- imum limitations given by the limits menu. Additionally each channel can become reversed. 4.3 Trainer mode To use trainer mode, we need two separate radios..One radio works as a students radio and the other works as a trainer radio Please note that the students radio must have the power-button switched off..

  • Page 28: Chapter 5: Programming Examples

    5 Programming examples Programming examples Basics: Unlike other radios, there are no ready-mixed programs (Plane, Heli). This makes the programming more complex, but less restrictive. The solution shown here is very flexible. However, setting the model with the desired functions may take a little more thought, but the system is very easily understood.
  • Page 29: Explanation

    5.1.3 Explanation The control functions RUDder, ELEvator and THRottle are transferred 1:1 to the outputs 1, 2 and 5.. P1 (airbrakes) will output both channel 3 as well as 4. Here only positive values are taken into account because otherwise the negative values of P1 would result in flaps movement into the wrong direction.
