用于MATRIXVOICE的ESP32HAL-httpswww.matrix.oneproductsvoice_C+.zip

# MATRIX Voice HAL for ESP32 This is the official set of ESP-IDF components for [MATRIX Voice](https://www.matrix.one/products/voice). ## Get Started **MATRIX Voice ESP32** has an ESP-WROOM-32. To develop applications for MATRIX Voice ESP32 you need: * **PC** with either Windows, Linux or MAC operating system. * **ESP32 Toolchain** to compile applications for ESP32. * **ESP IDF**, the API for the ESP32. * **Raspberry PI** to connect the MATRIX Voice and upload the Software into the ESP32 and keep updated the **FPGA** firmware. ## Pre-Requisites (Raspberry Pi) Install the MATRIX Voice software in the **Raspberry PI**. It keeps the **FPGA** firmware updated and install few tools to flash the ESP-WROOM-32. ### Dowload Rasbian Stretch Download the latest **Raspbian Stretch** and set up the Rasberry Pi. More information in:[https://www.raspberrypi.org/documentation/installation/installing-images/README.md](https://www.raspberrypi.org/documentation/installation/installing-images/README.md) ``` https://downloads.raspberrypi.org/raspbian_lite_latest https://downloads.raspberrypi.org/raspbian_latest ``` ### Install MATRIX Voice Software ``` # Add repo and key curl -L https://apt.matrix.one/doc/apt-key.gpg | sudo apt-key add - echo "deb https://apt.matrix.one/raspbian $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/matrixlabs.list # Update packages and install sudo apt-get update sudo apt-get upgrade # Installation sudo apt install matrixio-creator-init # Reboot sudo reboot ``` ## ESP-IDF and Toolchain Setup (PC) ### ESP32 toolchain Follow the instructions according to your operating system to set up the ESP32 toolchain: [https://esp-idf.readthedocs.io/en/latest/get-started/index.html#setup-toolchain](https://esp-idf.readthedocs.io/en/latest/get-started/index.html#setup-toolchain) ### ESP-IDF development framework See setup guides for detailed instructions to set up the ESP-IDF: [https://github.com/espressif/esp-idf](https://github.com/espressif/esp-idf) #### Linux It is recommended to set the PATH and IDF_PATH environment variables in the ~/.bashrc file ``` export PATH="$PATH:<route to toolchain>/xtensa-esp32-elf/bin" export IDF_PATH=<route to ESP-IDF>/esp-idf ``` ## Cloning, Compiling & Deploy (PC) Clone de repo MATRIX Voice HAL ``` git clone https://github.com/matrix-io/matrixio_hal_esp32.git ``` Everloop example ``` cd matrixio_hal_esp32/examples/everloop_demo make menuconfig ``` Configure the ESP framework environment. Save your configuration and then exit the application. Default configuration works well. Just skip the setup pressing *Exit* in the first window.  Now build the application with: ``` make ``` To deploy and flash the application into the ESP it's necessary to connect the MATRIX Voice to a Raspberry PI. ``` $ export RPI_HOST=pi@RASPBERRY_IP_ADDRESS $ make deploy ********************************* Copying files to the Raspberry PI ********************************* pi@RASPBERRY_IP_ADDRESS password: bootloader.bin 100% 19KB 5.7MB/s 00:00 arc_demo.bin 100% 382KB 10.7MB/s 00:00 partitions_singleapp.bin 100% 3072 2.6MB/s 00:00 ********************************* Programmig the ESP32 ********************************* pi@RASPBERRY_IP_ADDRESS password: ----------------------------------- esptool.py wrapper for MATRIX Voice ----------------------------------- esptool.py v2.2 Connecting......
