Hi,I use STM32F103C8T6 a GPIO input pin to read a high or low signal from another GPIO output pin, and connect a 3Mohm resistor between two pins, and I notice touching GND with hand will influence the signal status, than I measure the resistance betw...

Hi,I am a newbie and trying to compress RGB image data to JPEG and save to SD card. Step by step I monitor the debugging of CubeMX, which is very useful to me. And finally I see it can not pass the jpeg_set_default() function due to "out of memory", ...

Hi Pedro,Can you recommend a MCU with such interface? and better have CAN interface too. STM32 series will be good to use. Thank you!

Hi, it is intended for hand detection, but touching GND will also be detected which is surprise. 3Mohm vs. 10(or 6Mohm), I want to increase the resistance to GND so that GND will not influence signal that much.

Hi @Imen.D ,Thank you for quick reply. I perhaps think another way to save jpeg data to SD card.I notice DCMI has a JPEG mode, I guess that means it can transmit JPEG data stream from CAMERA to the internal memory, am I correct? If so, then can I dir...
