The 16 hexadecimal of the picture showed on OLED is produced through PCtolCD. The detailed method can refer to: Lesson 2--Microduino OLED Usage Step 4: By adding voice prompt function, medical workers can get voice notice when someone calls. Stack Microduino-Amplifier and Microduino-SD on the basis of the three modules, as follows: Re-download MicroduinoHospitalCallReciverSound.ino program to Core+. Save audio files you want to play into SD card of Microduino-SD. As for how to make audio files, please refer to: Microduino LM4863 Music player -301KIT
