3, if the data is to be displayed on the computer monitor, there are two cases, one is the single chip microcomputer to do collection, and then transmitted to the computer host through the serial interface, the host uses vb or vc programming, and then the serial port transmission to the data collection and display. The second is that you make a display drive circuit on the board of the microcontroller. Then put to displayThe same as the graphics card, it is transmitted directly to the display through the circuit.

4, yes, STM32F303VCT6 is a single chip computer, 32-bit microcontroller chip in 100-LQFP package.
5, STM32 is a 32-bit flash memory microcontroller based on the ARM Cortex M3 processor core, which is a relationship between inclusion and inclusion. STM32 opens up a new free development space for MCU users and provides a variety of software and hardware AIDS that are easy to use. The STM32 core is based on the ARM Cortex-M3 core designed for embedded applications requiring high performance, low cost and low power consumption.
6, STM32: ARM32 bit Cortex-M3 CPU, maximum operating frequency 72MHz, 25DMIPS/MHz. Single cycle multiplication and hardware division. Advantages Different ARM: small size, low power consumption, low cost, high performance stm32 MCU has ad conversion chip? ; Support Thumb (16-bit) /ARM (32-bit) dual instruction set, can be well compatible with 8-bit / 16-bit devices stm32 MCU has ad conversion chip? ; Heavy use of registers, instructionsFaster execution.
STM32F103 series chips, the maximum operating frequency can be 72M using 8M external crystal oscillator, generally also need to use the internal PLL phase-locked loop for frequency doubling compared to the internal 8M RC oscillator external crystal frequency stability is better if usefulAn external crystal oscillator is recommended for frequency measurement or timing functions.
MHz=8*10^3KHz=8*10^6Hz, that is, 8 million Hz. Crystal oscillator: the so-called quartz crystal resonator and quartz crystal oscillator collectively. Refers to a quartz crystal according to a certain azimuth Angle cut thin slice (referred to as wafer), quartz crystal resonator, referred to as quartz crystal or crystal, crystal oscillator; The crystal element that adds IC inside the package to form an oscillating circuit is called a crystal oscillator.
The former provides the reference frequency required for the operation of the microcontroller, which is equivalent to its heart, also known as the main oscillation source/ Master clock source; The latter, after 32768 frequency division, gets an accurate 1Hz pulse, which is used in the Real Time Clock module to achieve timing, stopwatch, alarm and other clock-related functions.
and 1M both refer to the operating frequency of the crystal oscillator, in Hz. The 32768Hz crystal oscillator is generally used in clock circuits, because a 1S timing period can be obtained by 15 divisible frequencies. If the 1MHz crystal oscillator is used, the frequency is low, generally the single-chip microcomputer runs without high speed requirements, which can reduce power consumption and reduce external radiation.
In the STM32, there are five clock sources, namely HSI, HSE, LSI, LSE and PLL. STM32 microcontroller crystal oscillator (YXC Yangxing crystal oscillator) ①HSI is a high-speed internal clock, RC oscillator, the frequency is 8MHz. HSE is a high-speed external clock that can be connected to a quartz/ceramic resonator or an external clock source with a frequency range of 4MHz~16MHz. LSI is a low speed internal clock, RC oscillator, frequency of 40kHz.
2, STM32F1 MCU has a 12-bit ADC processor, if the 12-bit has met the sampling requirements, then do not need to access the ADC chip (such chips are generally very expensive), can be connected to the external ADC chip such as ads1256 (24-bit), AD7689 (16 bits). The input clock of the ADC must not exceed 14MHz, which is generated by PCLK2 by frequency division. The maximum conversion time is 1us, and the ADC loses some accuracy when the input clock exceeds 14MHz.
3, ADC conversion is the input analog semaphore, MCU conversion into digital quantity. The digital quantity must be read after the conversion is completed, and the reading of a channel is called the sampling cycle. Sampling period generally = conversion time + read time. And conversion time = sampling time +15 clock cycles.
4. Numerical quantity refers to0 and 1 are right. Look at the manual, the ADC of STM32 is 12 bit precision, that is, the number range is 0 to 2^12 (2 to the 12th power, that is, 12 bits of binary number), that is, 0 to 4096 (decimal). Therefore, the analog quantity of the sample is 0~3V analog voltage, and the corresponding digital quantity is 0~409.
5, part of the STM32 has two independent core ADCs. It can be used to capture two acquisition quantities at the same time, or to collect different/same acquisition quantities at intervals to reflect the time domain difference/increase the sampling speed. As for how much it makes senseTao does not know whether it is the same as ordinary, that is, multiple different sample quantities can be collected at different times.
