Then it outputs the graph from this position. Mar 6, 2024 · I am having trouble with microcontrollers (STM32s mainly) on custom PCBs. Input tolerates 5V max. 3V, that means you can read 0-3. You can use this oscilloscope to capture frequency signals up to 5kHz. Do you mean 500 MHz or 500 kHz? That MCU seems to have a A/D sample time of 1 us ("2x 12-bit, 1 µs A/D converters (up to 16 channels)"), which gives you 1 million samples per second (or 2x that if you interleave both converters), which would be good for 500 kHz, not 500 MHz. ATtiny85 or ATtiny45 can be used. I want to get an oscilloscope to help me solve these issues. Nov 20, 2023 · To avoid this, the oscilloscope reads more samples than can fit into the display and then finds the position in the saved array where the input graph crosses the threshold value in the selected direction (either up or down, this option also is available in real oscilloscopes). The oscilloscope is based on the STM32F103 microcontroller which has 2 fast, 12-bits ADC and it samples the signal to be examined (after it has passed condition elements, like a network of resistors capacitors and diodes) on board. Software trigger starts the sampling when the input signal crosses zero. A portable PC based oscilloscope using ATmega 328 micro-controller is developed. See full list on circuitdigest.
