Download this repo
-
install Python dependencies [add needed deps]
pip install protobuf
-
Flash the µC with the newest release [see this link] (doc/flash_stm32_fimware.md)
-
Connect µC and PC directly via Lan (or over an switch with DHCP anabled to 192.168.2.x Subnet)
-
In case you are working behind a firewall, set an exception for incoming UDP packets from the IP address of the Smartup Unit on port 7654.
-
Set ip Adress of pc to 192.168.0.200
-
Power on µC Board
-
Observe Display and LEDS see Picture
-
Start Python Interpreter and run /tools/MET4FOFDataReceiver.py
-
Start data Receiver node with:
DR=DataReceiver("192.168.0.200",7654)
If every thing works correctly you will see that a new sensor is found
Data receiver now running wating for packets
FOUND NEW SENSOR WITH ID=hex0x37300000==>dec:925892608
Attach your callback function to Sensor
DR.AllSensors[925892608].SetCallback(DumpDataMPU9250)
The software was and is created with SW4STM32 (gcc). SEGGER Systemview can be used for debugging.
