Re: Question about demosaicing alogrithm
Hi aqqz, Can you share the output image? If the colors are far off, perhaps the demosaicing is applied with a wrong shift, thus interpreting the colors wrong. If the green tint is subtle, this might be improved with a better demosaicing algorithm. The current one is very basic. For further reading c...

Re: AI deck firmware update
If you can afford to wait, we are looking into building a solid pipeline for any STM32 <-> NINA <-> GAP8 communications. Perhaps sometime in the future an implementation like the one you mention will be much easier to implement.

Re: How to save color images when using Crazyradio
There is some reference to color encoding in the gap_sdk. I could not get that to work though. We are now investigating streaming raw image data, instead. We found that JPEG encoding takes a long time anyways, so it might even improve performance. Especially if you do the demosaicking off-board.

Re: AI-deck GAP8 flash issue
I'm glad you got it to work. Curious behavior! We've taken note.

Re: AI deck firmware update
Thank you for replying and sorry for late Yes, I'm trying to control multiple CF using Wifi. Because I think wifi is better way to control multiple CF than bluetooth (Crazyradio PA). Does it mean that the custom firmware you mentioned changes the port in the link below ? If not, can you tell me how...

Re: AI-deck GAP8 flash issue
Hello Wenda, Yes, the printout in the terminal looks good! All I can think of to verify your code is running is through some peripheral (LED, streaming over WIFI, communicating over UART with STM32). I do believe you have to reboot your GAP8 chip before it actually runs flashed code. (have you tried...

Re: How to save color images when using Crazyradio
Hi Noah, With the buffer format in RGB565 you will want the image to stream to be in that same format. The default demosaicking function creates RGB888 images. I made some changes to my demosaicking function, and managed to successfully save the RGB565 image with WriteImageToFile. However, the Pytho...

Re: Cannot testing the Himax camera
Hi Mathilda,
Curious... Are you using the same JTAG debugger, too?
We have seen similar unexpected behavior of the GAP8. I have found that it can help to first connect the JTAG debugger, before powering on the board. Give that a try and let me know if it works!

Re: AI deck firmware update
Hi Jason! I connected AI deck and PC, but there is no response such as the light on the AI deck. Is there anything to prepare before using olimex arm-usb-tiny-h? The JTAG debugger does not provide power, so you will have to power it some other way. Easiest is to mount the AI-deck on a Crazyflie and ...

Re: trying to change the gapflow-mnist example
Hi Elad! Specifically, where the constructor "modelCNN" is implemented (?) This is determined by a prefix, in this example set in common.mk Perhaps this is done to clarify what CNN will be called from the application code (although the prefix "model" doesn't tell you much), but I...
