*  startup\_stm32f10x\_ld\_vl.s: for STM32 Low density Value line devices
 *  startup\_stm32f10x\_ld.s: for STM32 Low density devices
 *  startup\_stm32f10x\_md\_vl.s: for STM32 Medium density Value line devices
 *  startup\_stm32f10x\_md.s: for STM32 Medium density devices
 *  startup\_stm32f10x\_hd.s: for STM32 High density devices
 *  startup\_stm32f10x\_xl.s: for STM32 XL density devices
 *  startup\_stm32f10x\_cl.s: for STM32 Connectivity line devices

cl：互联型产品，stm32f105/107系列

vl：超值型产品，stm32f100系列

xl：超高密度产品，stm32f101/103系列

ld：低密度产品，FLASH小于64K

md：中等密度产品，FLASH=64 or 128

hd：高密度产品，FLASH大于128

/* Tip: To avoid modifying this file each time you need to switch between these devices, you can define the device in your toolchain compiler preprocessor. - Low-density devices are STM32F101xx, STM32F102xx and STM32F103xx microcontrollers where the Flash memory density ranges between 16 and 32 Kbytes. - Low-density value line devices are STM32F100xx microcontrollers where the Flash memory density ranges between 16 and 32 Kbytes. - Medium-density devices are STM32F101xx, STM32F102xx and STM32F103xx microcontrollers where the Flash memory density ranges between 64 and 128 Kbytes. - Medium-density value line devices are STM32F100xx microcontrollers where the Flash memory density ranges between 64 and 128 Kbytes. - High-density devices are STM32F101xx and STM32F103xx microcontrollers where the Flash memory density ranges between 256 and 512 Kbytes. - High-density value line devices are STM32F100xx microcontrollers where the Flash memory density ranges between 256 and 512 Kbytes. - XL-density devices are STM32F101xx and STM32F103xx microcontrollers where the Flash memory density ranges between 512 and 1024 Kbytes. - Connectivity line devices are STM32F105xx and STM32F107xx microcontrollers. */
