I’m working on integrating the HM01B0 camera module with a SparkFun MicroMod Artemis Processor mounted on the Machine Learning Carrier Board. I’m using the SparkFun HM01B0 Arduino Library, but I’m encountering several issues when trying to run the Example1_StopMotion sketch.
When using the code from the main branch, I get a “platform not supported” error. To work around this, I switched to the AddMicroMod branch. However, the pin configuration defined in SparkFun_HM01B0_Camera_ArduinoLibrary/src/platforms/apollo3/include/hm01b0_platform_apollo3.h does not match the documentation provided in the MicroMod Machine Learning Carrier Board Hookup Guide.
To address this, I manually attempted to map the pins according to the configuration found in the library:
#elif defined(ARDUINO_AM_AP3_SFE_ARTEMIS_MICROMOD)
// These will be in the MM variant
#define G0 40
#define G1 42
#define G2 44

#define CAM_HSYNC 65

#define HM01B0_IOM_MODULE 4
#define HM01B0_I2C_CLOCK_FREQ 100000
#endif
Despite these adjustments, when uploading the code, I receive the following error:
Camera.begin() failed with code: 1
Is there a working example available for this specific hardware configuration, or alternatively, for the nRF52840 processor?
Does the nrf52840 throw the same error code?
The nRF52840 is encountering a pin configuration error when attempting to initialize the hardware

I previously ran the Blink example to verify that both my board and processor are functioning correctly, and it was successful. The issue lies with the camera. Is there another example available, or perhaps a different camera that is compatible with either of my two configurations?
Artemis + Machine Learning MicroMod
nRF52840 + Machine Learning MicroMod
Not that I’m aware of…the other option is to try a 3rd processor but only if you’re up for more rounds in the gym, so to speak :-/
I can probably help with some store credit if so (if you’ll report back your results!)
