FAQ on EVB

This article mainly introduces issues that users may encounter when starting to learn QuecPython and building a development environment based on the official development board or a self-designed circuit board. Issues involving the development of specific software and hardware functions are not covered in this article. Please refer to other chapters.

EC600S EVB and module serial port correspondence diagram

The serial port location of the EC600S EVB (EC600S_QuecPython_EVB_V1.x) is as follows:

The serial port connected to the board cannot communicate

Pay attention to whether the interface is 1.8V or 3.3V, and the level must be matched for normal communication.

Why doesn’t the light bring up when the USB cable is connected

Check the module voltage to ensure that the module's 3.8V is stable and use battery power if necessary.

What are the precautions when testing the TTS function of the EC600SV1.1 QuecPython development board?

The peripheral is a connected to the speaker, while the "microphone" is configured in TTS.

Since a power amplifier is added in V1.1, you need to pull up (hardware pull-up) pin58 of the socket in module (the enable pin of the power amplifier), or enable it via command "audio_EN = Pin(Pin.GPIO11, Pin. OUT, Pin.PULL_PD, 1)”.

The power of external speakers is limited, which shall be less than 8R 2W.
