stm32f103zet6是不是能兼容c8t6和t8u6代码？
stm32f103有的功能407都有，并且这些功能的引脚完全兼容，只是程序不同而已。。。
而stm32f407有的功能103不一定有，因为407强大些。。。。。。希望对你有用
stm32如何输出数量可控的脉冲
单脉冲法，需要一个脉冲中断一次，中断次数多，影响效率
一个定时器输出PWM，另一定时器进行中断计数
用主从定时器门控方式
用一个定时器（从）作为另一个定时器（主）的外部时钟触发源
高级定时器T1、T8的重复计数方式，RCR计数中断，看手册好像这种方式最简单，能满足一部分人要求，缺点是寄存器只有8位，最多实现255个脉冲计数输出。
为什么用Jlink向STM32烧写程序后，机器运行反应程序根本没有变化更新
应该是你烧写位置问题，如果是JLINK的话你不可能把之前的烧到片子里面去，说明jlink工作正常，你尝试写个最简单的test程序试试，记住不要bootloader哦！
IC MCU STM32L412C8U6 是32位的单片机吗？
是的。这是一颗Cortex-M4内核的32位微控制器。
The STM32L412xx devices are ultra-low-power microcontrollers based on the high-performance Arm® Cortex®-M4 32-bit RISC core operating at a frequency of up to 80 MHz. The Cortex-M4 core features a Floating point unit (FPU) single precision that supports all Arm® single-precision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) which enhances application security. The STM32L412xx devices embed high-speed memories (Flash memory up to 128 Kbyte,40 Kbyte of SRAM), a Quad SPI Flash memories interface (available on all packages) and an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses and a 32-bit multi-AHB bus matrix.
The STM32L412xx devices embed several protection mechanisms for embedded Flash memory and SRAM: readout protection, write protection, proprietary code readout protection and Firewall.
The devices offer two fast 12-bit ADC (5 Msps), two comparators, one operational amplifier, a low-power RTC, one general-purpose 32-bit timer, one 16-bit PWM timer dedicated to motor control, four general-purpose 16-bit timers, and two 16-bit low-power timers.
In addition, up to 12 capacitive sensing channels are available.
They also feature standard and advanced communication interfaces, namely three I2Cs, two SPIs, three USARTs and one Low-Power UART, one USB full-speed device crystal less.
The STM32L412xx operates in the -40 to +85 °C (+105 °C junction) and -40 to +125 °C (+130 °C junction) temperature ranges from a 1.71 to 3.6 V VDD power supply when using internal LDO regulator and a 1.00 to 1.32V VDD12 power supply when using external SMPS supply. A comprehensive set of power-saving modes makes possible the design of low-power applications.
Some independent power supplies are supported: analog independent supply input for ADC, OPAMP and comparator. A VBAT input makes it possible to backup the RTC and backup registers. Dedicated VDD12 power supplies can be used to bypass the internal LDO regulator when connected to an external SMPS.
The STM32L412xx family offers six packages from 32 to 64-pin packages.
