AllenCK ESP32 SNOW

HardWare:

• CPU:Xtensa Dual-core 32-bit LX6 microprocessor(s),up to 600 DMIPS
• RAM:4MB(external)+520K(internal)
• ROM:4MB(external)+448(internal)
• WM8978:mclk from gpio0,48k 32bit 2channel
• MPU6050:3-Axis accelerator and 3-Axis gyro or MPU9250
• BQ24075:Li-ion Charge and power path manage
• Expand all gpio

SoftWare Component:

• a based bsp
• a webserver framework(it's easy to use)
• a websocket-server
• mp3 deocde(helix and mad)
• lightweight http client
• a simple PI(D) algorithm to fuison accel and gyro to euler and quaternion

ftp-server(about sd card)

Demo:

• webradio
• bluetooth audio
• webcontrol
• baidu_rest_api_rsa
• ble gateway
• 3d show and control

Build:

1. git clone https://github.com/espressif/esp-idf.git
2. git checkout release/v3.3
3. git submodule init
4. git submodule update
5. git clone https://github.com/allenck/esp32_snow.git
6. cd esp32_snow/example
7. choose a demo and compile,if failed you can try rm the build dir and build again.

Examples

• To support the MPU9250 3 axis sensor, https://github.com/natanaeljr/esp32-MPU-driver must be installed. These modules must be downloaded into the components directory. This library also requires either the I2Cbus or SPIbus be present in $(home)/esl/libraries.
• To try out the example, load the '3d_show.html' in your browser. ip-address/3d_show/3d_show.html
• The 'bt_speaker example will not compile with the current version of esp-idf. This causes the other examples also to fail. Adding EXCLUDE_COMPONENTS:= bt_speaker to the example's Make file allows the to compile ok.

Todo List:

• a perfect project config(use make menuconfig)
• apple home assistant
• such as qplay protocol
• other funning things.
