STEVAL-STWINKT1 Board: save ADC data to sd card - embedded

I am using STEVAL-STWINKT1 Board to capture ADC data to SD Card.
Please help me with this-
I am not sure if I can see the plot and FFT of my ADC signal on the Bluetooth App.

STM32 External LED blink

I am trying to Blink external LED using STM32CubeIDE and Proteus
while (1)
{
HAL_GPIO_TogglePin(LED_GPIO_Port, LED_Pin);
HAL_Delay(100);
}
[)2
The LED doesn't blink
I am assuming that you have configured the pin to be output correctly with no pull up or pull down resistor. Hence you will need to terminate the LED into the ground instead of 3.3V.
In the event there is no pull up or pull down resistor, the pin is neither high or low, the pin is in a "z-state" hence when you toggle the LED from low to high there is no potential difference between the pin and the LED so no current flows, and when the pin goes from High to low, the diode property (only allows current flow in one direction) of the LED doesn't let current flow into towards the board.
The Problem Solved.
First the polarity of the LED.
Second the library of the blue pill on proteus doesn't support STM32FC103C8 that I selected on STM32CubeIDE. STM32FC103C6 should be selected instead.

Yellowstone tablet camera sensor

At a company I work for we're developing a 3D Reconstruction app that can be downloaded to common Android devices. In order for the reconstructions to work the best, we need to input the devices' camera sensor size (specifically the CCD width). Through the app's Play Store administration page we've seen several users using something called "Google ATAP Project Tanto Tablet (Yellowstone)". Can anyone help us know what sensor size does that tablet has? This would improve the reconstructions made on that device.
Thanks in advance!
As far as I understand, Tango Yellowstone tablet uses a combined RGB and IR camera from OmniVision, OV4682 RGB IR. You can find more specifications here:

Sony ILCE-QX1 camera, image size during remote capture with no memory card

When remotely capturing still images using 'actTakePicture', on the Sony ILCE-QX1 camera it is possible to remotely capture and obtain images when no memory card in inserted.
However, the captured image size is this case is only 1616x1080, whereas if the memory card is inserted full image size 5456x3632 is obtained.
"setStillSize",is set to ["3:2","20M"], and "setPostviewImageSize" is set to "Original" - but this does not seem to have any effect when the memory card is not present.
The reason I would like to shoot without card (or without saving to card) is to save the time it takes to same the image to the card.
Q: is it at all possible to capture full image size with no card or without saving to the card on the Sony ILCE-QX1? (perhaps internal memory is not sufficient although it seems strange as burst mode typically uses internal memory), and if so how?
thank you!
Unfortunately is it not possible to capture a full size image without a memory card on the QX1.

Key Difference between Active IR image and depth image in Kinect V2

I just have a confusion in understanding the difference between the Active IR image and depth Image of Kinect v2. Can anyone tell me the what special features Active IR image have as compare to depth image?
In the depth image, the value of a pixels relates to the distance from the camera as measured by time-of-flight. For the active infrared image, the value of a pixel is determined by the amount of infrared light reflected back to the camera.
Sidenote:
I think there is only one sensor that does both these. The Kinect uses the reflected IR to calculate time of flight but then also makes it available as an IR image.

characteristics of Kinect V2 Infrared images

I want to use Kinect v2 and record Depth, IR, and RGB images. About the characteristics of depth image we all know that depth image shows distance of person from the Kinect sensor and as we move close or far from the sensor the depth values changes. However, I want to know about the characteristics of IR image. If the person is standing in front of sensor and after some time he forward does the IR image show any change?
The IR image is simply the intensity of reflected IR radiation as emitted by the Kinect. The IR image will not show any change in distance other than the illumination tapering off if you move too far away and the sensor saturating if you have are too close or have a reflective surface in front of the Kinect.
