ESP32 WROOM 32D - Develop a Proof of Concept prototype -Firmware development
$3000 HKD
Paid on delivery
You can realize the protoype using a breadboard with a ESP32 WROOM 32D. The prototype will:
Part A
Bluetooth communication:
1. when GPIO A at the ESP32-WROOM is triggered with a 1, wake up from deep sleep mode and enable Blueooth. Otherwise, turn off alll wireless functions in order to save power
2. pair with a Bluetooth device (Windows PC /Mac/iPhone/Andorid phone)
3. download music files in Ogg format from the Bluetooth device and save the files to a SD card. The SD card is connected to ESP32-WROOM
4. a user can manage the music files using the Bluetooth device
5. unpair the Bluetooth device and turn off alll wireless functions in order to save power.
Part B
Select Ogg music files to play:
1. When GPIO B at the ESP32-WROOM is triggered with a 1, wake up from deep sleep mode and read values from GPIO C, D, E.
2. Based on the values of GPIO C, D, E, F (16 combinations here), selecte one of the 16 Ogg music files to play.
3. Using I2S to send the music data to another chip to play (Adafruit I2S 3W Class D Amplifier Breakout - MAX98357A).
4. After the Ogg music files is finished, enter deep sleep mode again.
You will make two videos for part A and part B to show everything is working. If you do not have the parts, we can buy and ship them to you but this make take a long time and we may need to pay duties.
Payment:
10% for a full schematic
25% for video of Part A
25% for video of Part B
20% for providing all the files
20% after we test the files successfully.
