MLX90640 Thermal Imager

mlx90640, although the price is not cheap, it is much cheaper than the finished product (and the functions are correspondingly less). The main control is stm32f401ccu6, the charging chip is ip2312, and the external flash is welded with an 8m "large" flash. It feels like saving pictures. It's enough. The screen uses a 2-inch SPI screen. I regret not using the parallel port function. The refresh is a bit slow (it works) and I am too lazy to change it. The circuit board picture is as follows! [IMG_20211220_204601.jpg] Since it is a product, I drew it A shell, (the button JLC said it was too small to be pressed, so I finally went to TB to press it)! [Shell.jpg] The program part uses bilinear interpolation to adjust the sensor pixels to the screen display size minus a little bit left on the edge. Empty, used to write the interface, using ready-made functions in the dsp library, the actual measured and hand-written processing speed is no different. I added a file system, saving pictures is a bit slow, it takes several seconds! [screenshot.jpg] Actual effect! [IMG_20220216_210000. jpg]
