Lesson 3 of 7
Edit parameters
Most blocks have parameters — a low-pass filter's time constant, a Gain's multiplier, an Integrator's limits. You edit them in the property editor on the right.
Select a block
Click a block to select it. The property editor on the right fills in with that block's settings — its name, type, and every parameter it exposes.
Change a value
Edit a field and the change takes effect immediately. With the low-pass block
selected, try changing its time_constant: a larger value makes it
respond more slowly to its input. You can also rename a block — typing a new
label updates it live, as in the clip above.
Live validation
Values are checked as you type. If you enter something invalid — an out-of-range limit, a frequency a peripheral can't produce, a pin that's already in use — the editor flags it right away instead of letting you discover it at simulation or flash time.
Tip: the same live checking covers hardware resources. When you target an STM32, Block Designer validates pin and peripheral assignments against the actual chip — so conflicts surface while you design, not after you flash.
Your three-block chain is now configured. Before running it, let's see how to load a complete, ready-made design.
