I am unable to compile the examples , hello_world_arcada and micro_speech_arcada , on the adafruit website found here on my Circuit playground bluefruit microcontroller.
-
I installed the Adafruit_Tensorflow_Lite library in my arduino ide as mentioned in the site however it turns out that when compiling the examples they have numerous missing files. So i downloaded this tensorflow git hub repo and then transfered the missing files into the Adafruit_Tensorflow_Lite library.
-
I am now facing this error for the missing files : am_bsp.h,am_mcu_apollo.h, am_util.h , i cannot locate these files on the repo or on google.
Can anyone let me know where i can find these files or a way to compile the code ?
- The error is shown in the pic below of the missing file am_bsp.h when using Arduino IDE to compile:
- My code is shown below:
