Sparkfun and Hm01b0 connection

I am interested in the low-power solutions of sparkfun and Hm01b0 and am trying to detect people.
First, I tried to connect the two modules and check the photos, but the following error occurred. Can anyone help me?

error message as follows.
c:\Users\SMLEE\Documents\Arduino\libraries\SparkFun_Himax_HM01B0_Camera\src\hm01b0_c\src\hm01b0_c.c:20:2: error: #error “Unsupported platform: Submit an issue / pull request to GitHub - sparkfun/SparkFun_HM01B0_Camera_ArduinoLibrary: Extensible library to use the Himax HM01B0 camera in Arduino to add support for your target”
#error “Unsupported platform: Submit an issue / pull request to GitHub - sparkfun/SparkFun_HM01B0_Camera_ArduinoLibrary: Extensible library to use the Himax HM01B0 camera in Arduino to add support for your target”

Looking at the source, it looks like this. How should I set AM_PART_APOLLO3?

hm01b0_c.c

#include “hm01b0_c/include/hm01b0_c.h”
#include “hm01b0_c/include/hm01b0_walking1s_01.h”
// #include “hm01b0_platform.h”

// Conditionally Include Platforms
#if defined (AM_PART_APOLLO3) &&
defined (ARDUINO_SFE_EDGE)
#include “platforms/apollo3/include/hm01b0_platform_apollo3.h”
#else
#error “Unsupported platform: Submit an issue / pull request to GitHub - sparkfun/SparkFun_HM01B0_Camera_ArduinoLibrary: Extensible library to use the Himax HM01B0 camera in Arduino to add support for your target”
#include “platforms/arduino_generic/include/hm01b0_platform_arduino_generic_c.h”
// todo: add generic Arduino implementation
#endif // platform inclusion

AM_PART_APOLLO3 is defined when you compile for an Artemis board with Library V1.2.3.
Looks like you are using V2, and there are issues detected and solved earlier. See BSP version 2.0.5 and 1.2.1 compatibility

I haven’t been able to check the photos yet, but the issue has been resolved. T
hank you very much!

Hi?

The board I use is apollo3 edge, and the camera is hm01b0. I plan to use both in future tensorflow low-power projects. However, the camera was compiled using the method you suggested, but the following message appears. It is not a defect in the camera hardware. Is there any solution?

message
Camera.begin() failed with code: 1
Calibrating Auto Exposure…

source is as follows(Example1_StopMotion.ino)
// Start the camera
if(myCamera.begin() != HM01B0_ERR_OK){
SERIAL_PORT.print("Camera.begin() failed with code: " + String(myCamera.status) + “\n”);
}else{
SERIAL_PORT.print(“Camera started successfully\n”);
}

I noticed when I referenced you to my github side that the libmbed- archive was based on library 2.0.6. In the meantime we are on V2.2.1. Due to the flue I am bound to home anyway, so started working on a V2.2.1 version, which I tested successfully on my EDGE. I received the picture as expected with the python-code running on the Ubuntu side.

I have just updated the github link with the new libmbed-archive. The ./includes folder did not change. apollo3/hb01b0 at master · paulvha/apollo3 · GitHub

Give it try and let me know the results.

Thank you for your help.
After deleting all installed programs and running it again, it worked. However, I am sharing it because there are a few modifications.

  1. install arduino IDE 2.3.4

  2. add URL
    https://raw.githubusercontent.com/sparkfun/Arduino_Boards/master/IDE_Board_Manager/package_sparkfun_index.json

  3. install board manager
    Sparkfun Apollo3 Board

  1. not change a libmbed-os.a

Thanh you very much!

Thanks for the update, good to hear it works for you. couple feedback

  • The message you got was a warning and can be neglected. no action needed.
  • You installed V1.2.1. There is a better version V1.2.3 with bugfixes
  • The Libmbed.a is NOT used in V1. It is only for V2.2.1
  • On V1 you can use the standard HB01B0 library from Sparkfun.
  • Not sure you need it, but V1 does not have Bluetooth
