3. Get started
MaixAmigo also uses MaixPy to get started with AIoT. Due to the particularity of the hardware, please use MaixPy after Configure amigo hardware(If not configured, the photos taken by the camera will be noisy) .
Before development, we need to understand and prepare related tools to reduce the pitfalls we have to follow because of insufficient preparation.
Steps to get started:
- Download the required drivers and software
- Connect the development board to the computer and install the USB driver
- Update the latest firmware
- Download and open the latest MaixPy IDE
- Connect MaixPy IDE to the development board Run MaixPy sample program
3.1. Software and hardware preparation
- Computer one
- MaixAmigo Development Board
- One reliable USB Type-C data cable: pay attention to a reliable data cable
- USB driver: Click me
- Kflash_gui: https://dl.sipeed.com/MAIX/tools/kflash_gui
- MaixPy IDE: https://dl.sipeed.com/MAIX/MaixPy/ide/_/v0.2.5
- Routine library: https://github.com/sipeed/MaixPy_scripts
3.2. install driver
When we get Maix Amigo and connect to the computer, we can open the device manager to check whether the serial port driver has been installed. The methods to open the device manager are:
This computer (right click) -> Properties -> Device Manager
Start menu (right click) -> Device Manager
Control Panel -> (Search) Device Manager
When our system is a Win10 system, the system will automatically install the driver for us, and if it is an old version of Win7, win8, we need to install it manually:
- Open the link in the previous section to download the driver
After the installation is complete, you can see in the device manager that two serial devices have been identified
3.3. Update the firmware to the latest version
After the user gets the development board, the on-board firmware may not be the latest version by default, so there will be more or less bugs during use.
We need to update the firmware version to the latest version at this time
View update method: Update Firmware
If you use the amigo development board, please burn the dedicated amigo firmware greater than or equal to v0.6.2_12 (for example: maixpy_v0.6.2_12_gf18990aa3_amigo_tft(ips)_xxxx.bin). The difference from the standard maixpy firmware is that it has built-in amigo Hardware configuration (config.json), and the screen types are divided into ips and tft. Burning any screen type firmware can be started, but the display of different screens will be abnormal (the normal red maixpy welcome page), so According to the actual situation, it can be burned and confirmed again.
