# Robotics_with_Ada

Robotics with Ada, ARM, and Lego

This program demonstrates interfacing to Lego NXT Mindstorms sensors and

effectors using Ada and low-cost ARM evaluation boards instead of the

NXT Mindstorms Brick.

For the touch sensor interfacing demonstration:

* The program displays output to the LCD screen of an STM32F429I Discovery

board, but does not rely on the specific board other than that. Make sure

the project gpr file matches the target board used.

* The touch sensor is expected to be connected to ground and the external

circuit in an active-low configuration (per the discriminant value

specified in the source code). Use the sensor's red or black wire for

ground, and the white wire for the input. If a different circuit is used,

providing an active-high configuration, change the discriminant accordingly.

* The discrete input is to be connected from the external circuit to PB4.

For the analog sensor interfacing demonstrations:

* You must have a pull-up resistor for the analog input pin connected to the

+5V power pin. Otherwise you will see odd input (and hence output) values.

* Note that the two demonstration programs use different STM32 Discovery

Kits. The project gpr files handle this difference directly, when

building, but of course you must use the corresponding board for

execution. The "demo_analog_sensors" demonstration uses the STM32F429I

Discovery board because it displays the inputs on the kit's LCD screen.

That LCD is the only real reason that particular kit is used. The other

demonstration program "demo_sound_sensor" is set up to run on an STM32F4

Discovery kit, because that one can drive an LED with PWM, unlike the

F429I kit. Other supported STM32F4 targets with those capabilities can

be used instead, with minimal changes.
