1，STM32F103ZET6总共可以同时使用多少路PWM

pwm方案如果频率和精度要求不高可以定时器软实现,硬实现基本就是一定时器4路,你找5个定时器以上的就行,ZE有6个肯定没问题,另外你还要看手册这些输出是不是有复用管脚,这得看你封装.

2，stm32f103zet6 有多少个gpio口

这个接5V 都是有超出其IC的性能的,我用STM32F103ZET6 的IO口外接过

莫非 4个串口？ uart4 不就是第四个吗？或者仅仅是引脚？

3，stm32f103zet6怎么读出gpio单总线的数据

STM32F103RBT6是 64脚封装，128K FLASH，20K RAM；STM32F103VET6是100脚封装，512K FLASH，64K RAM。

使用st提供的库文件中的启动文件即可,名字为“startup_stm32f10x_hd.s”,路径为:stm32f10x_stdperiph_lib_v3.3.0librariescmsiscmdevicesupportststm32f10xstartuparmstartup_stm32f10x_hd.s

4，STM32F103ZET6和STM32F103C8T6编程不一样吗

不太一样，如stm32f103zet6芯片使用的工程模板写入stm32f103c8t6，编译会出现错误。1、修改c/c++选项卡的宏定义2、启动文件也需要改一下，用md的（把c/c++选项卡中 stm32f10x_hd,use_stdperiph_driver 修改为 stm32f10x_md,use_stdperiph_driver）

是这样的，一个具体的STM32F103系列芯片的内存有多大，你看一下芯片上的型号就行了。 STM32F103XY 注意，XY是个代号，X是表示封装有多少个引脚，比如，如果X = Z，即STM32F103ZY,则表示这个芯片有144个引脚，如果 X = V,即STM32F103VY,系列有100。

5，请教stm32f2xx系列的GPIO的配置问题

给你个配置举例：void GPIO_I2C_Configuration(void) GPIO_InitTypeDef GPIO_InitStructure; /*!< sEE_I2C Periph clock enable */ RCC_APB1PeriphClockCmd(sEE_I2C_CLK, ENABLE); /*!< sEE_I2C_SCL_GPIO_CLK and sEE_I2C_SDA_GPIO_CLK Periph clock enable */ RCC_AHB1PeriphClockCmd(sEE_I2C_SCL_GPIO_CLK | sEE_I2C_SDA_GPIO_CLK, ENABLE); RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG, ENABLE); /* Reset sEE_I2C IP */ RCC_APB1PeriphResetCmd(sEE_I2C_CLK, ENABLE); /* Release reset signal of sEE_I2C IP */ RCC_APB1PeriphResetCmd(sEE_I2C_CLK, DISABLE); /*!< GPIO configuration */ /*!< Configure sEE_I2C pins: SCL */ GPIO_InitStructure.GPIO_Pin = sEE_I2C_SCL_PIN; GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF; GPIO_InitStructure.GPIO_Speed = GPIO_Speed_25MHz; GPIO_InitStructure.GPIO_OType = GPIO_OType_OD; GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_NOPULL; GPIO_Init(sEE_I2C_SCL_GPIO_PORT, &GPIO_InitStructure); /*!< Configure sEE_I2C pins: SDA */ GPIO_InitStructure.GPIO_Pin = sEE_I2C_SDA_PIN; GPIO_Init(sEE_I2C_SDA_GPIO_PORT, &GPIO_InitStructure); /* Connect PXx to I2C_SCL*/ GPIO_PinAFConfig(sEE_I2C_SCL_GPIO_PORT, sEE_I2C_SCL_SOURCE, sEE_I2C_SCL_AF); /* Connect PXx to I2C_SDA*/ GPIO_PinAFConfig(sEE_I2C_SDA_GPIO_PORT, sEE_I2C_SDA_SOURCE, sEE_I2C_SDA_AF); }GPIO_PinAFConfig(sEE_I2C_SCL_GPIO_PORT, sEE_I2C_SCL_SOURCE, sEE_I2C_SCL_AF); 这句语句分配为它的复用功能，可查看库的函数定义和说明。

同学，你好！应该是错在IO口配置那位置，因为USART2用的IO口不再是PA9和PA10。如果和我芯片一样STM32F103ZET6，那就应该是换成PA2和PA3了！自己仔细看下自己芯片是哪个IO口吧！望采纳！完蛋，没仔细看，你已经改了IO口的，那问题可能就是：如果用的是开发板的话，可能是没有把这个串口2引出来了。程序是没错的！
