【Fudan Microelectronics Automotive MCU FM33FT0A Series】+TSI Touch Software Usage [Copy link]

Fudan Micro has special information about the touch of this chip. It is also equipped with a special software for debugging, which is convenient for parameter debugging.

We generate a project ourselves. Currently, according to the board, I just simply used the following buttons.

You can see that the interfaces we use are specially reserved. Just pay attention to them when drawing the board.

The module is then configured with clock and current DAC compensation settings.

At the same time, configure the digital filter, all of which are done according to the official documentation.

After generating the project, we can select the serial port of our board simulator for testing. Debugging is done with this software.

The project is still the same as the case. If we did not choose to generate the debug serial port and clock, we still need to add our own code. Now we only need to compile, download and debug.

The software enters the debugging interface, then the port configuration, click Start, turn on the observation point in the upper right corner, and then operate the touch.

When you press it, a green light will appear and the timing will start. When the time is up, the signal will be forcibly interrupted to prevent continuous touching.

At the same time, this software also has a curve display function, which transmits all sensor data, making it more convenient for us to debug the touch.

If the user wants to use the status of what he pressed, he can directly add the above code in the loop to complete the status acquisition.

Look, his print is correct.

Summary: Fudan Micro has designed such a library independently and provided us with a generated software to simplify debugging the code. The graphical interface also displays data and the configuration of debugging parameters very intuitively.
