Basic operations on the 4x20 LCD screen

Whatever you do, you expect to have some output of the system. Sometimes there is a blinking LED, sometimes information about connected/disconnected network and some other time simply trace algorithm progress. In laboratories where you have physically connected MCU to your programming device (i.e. computer), you usually would choose Serial port to report about what is going on. However here all you have is access via the video stream.

Note, the video stream from the camera is limited in bandwidth and presents some 5-10fps maximum (usually around 1 fps) so you shouldn't change display content nor LED state faster than once every 2 seconds, to let you notice any change!

Target group

This hands-on lab guide is intended for the Beginners but other target groups may benefit from it, treating it as a tool for advanced projects.

Prerequisites

Provide prerequisite readings/hardware/software/software libraries/skills if other than stated in the Laboratory Description. If none, remove along with the header. Please note some of those may be common for all scenarios (i.e. mqtt library), so provide it in the laboratory description level, not in the scenario level.

Scenario

Describe scenario to let the user understand its idea and process. Write information about the approach, algorithm, etc. (depends on the lab). Provide useful information about protocols, assumptions, addresses (i.e. communication servers), credentials, etc.

Result

Describe expected result when scenario is finished.

Start

Write starting conditions, i.e. what to do at the beginning, what to pay attention before beginning, how the mechanical part should look like, etc.

Steps

Write some extra information if i.e. some steps are optional otherwise cancel this paragraph (but do not remove header).

Step 1

Describe activities done in Step 1.

Step n

Describe activities done in Step n.

Result validation

Provide some result validation methods, for self assesment.
