Audio

STM8L1528-EVAL evaluation board supports the following audio jacks

●

A speaker and stereo audio jack which is connected to the DAC outputs of

STM8L152M8T6 through an audio amplifier

●

An audio IN jack which is connected to ADC input of STM8L152M8T6 through a

microphone amplifier.

The speaker can be enabled by setting of JP3 to close and the Microphone output can be

connect or disconnect to STM8L152M8T6 by setting of JP9 to close or open, refer to Table 5

for details.

The LCD glass module has to be mounted in "IO" position for Microphone and headphone

plug event detection. Refer to Section 2.5: LCD glass module on page 10 for details.
