STEVAL-STWINKT1B这块开发板给人第一感觉就是板载传感器真是多，所以非常适合用来做STM家的传感 器评测。另开发板主控是用的STM32L4R9ZIJ6 MCU，其cpu基于Cortex-M4，最大频率120MHz。开发套件 自带了一块480 mAh的锂电池，STLINK-V3MINI调试器，以及一个外壳。完全组装起来后很漂亮，让人爱不释手。
linux开发环境概述
笔者长期在linux环境中干活，所以这次评测也以linux环境为例。开发环境软件上来说其实包括三大件：toolchain、项目工程编译管理和烧录调试。toolchain就用系统安装的arm-none-eabi-gcc，没安装 的读者可以看笔者其它开发板的评测，这里不赘述了。项目工程的编译笔者早期非常喜欢原始的Makefile，但后期MCU越来越复杂后切到cmake了。至于工具烧录和调试笔者特喜欢openocd与pyocd，但经笔者初步尝试，最新从源码编译的openocd成功烧录img后再openocd连接会报以下的错误，原因未知。
pyocd烧录同一个img没有此现象。另外说一句：用STM32CubeProgrammer烧录也没有此现象，说明openocd对STM32L4R9ZIJ的flash算法可能还有些兼容性问题，当然如果只用openocd调试是没任何问题的。所以笔者建议目前还是用pyocd吧。pyocd使用前需要安装下相应的Keil Pack包，STM官方已经上传至Keil官网，所以以下命令即可安装STM32L4R9ZIJ的pack包
pyocd pack install stm32l4r9zijx
点灯
下面开始大家喜闻乐见的点灯，但点灯之前有个问题源码基于什么来做。显而易见可以选择STM32CubeL4，但前面说过这个STEVAL-STWINKT1B开发板很特别，传感器特别多，STM官方甚至给它单独打造了一个名叫fp-sns-datalog2的github项目，使用上特别方便，用户甚至不用编译固件就能很方便的通过USB命令或者sdcard上的配置文件来使用它，那源码就基于它来开发吧。另外说一句：STM官方还有一个名叫fp-sns-datalog1的github项目，个人理解它与fp-sns-datalog2的区别应该就是底层的RTOS不一样，fp-sns-datalog1基于FreeRTOS，而fp-sns-datalog2基于ThreadX，两者都可以做代码基础，但笔者更喜欢ThreadX一些，所以选中了fp-sns-datalog2。
clone源码先：
git clone https://github.com/STMicroelectronics/fp-sns-datalog2.git
下面正式开始点灯之旅，先把样例工程拷贝一下
cp -a Projects/STM32L4R9ZI-STWIN/Applications/DATALOG2/ Projects/STM32L4R9ZI-STWIN/Applications/demo
经阅读STEVAL-STWINKT1B开发板开发板原理图可知，有两个LED可由用户控制，分别是LED1（蓝色）和LED2（橙色），分别接在了PE1和PD0两引脚上，修改Projects/STM32L4R9ZI-STWIN/Applications/demo/Core/Src/main.c加入点灯代码如下
<div class="blockcode"><blockquote>int main(void)
{
HAL_Init();
SystemClock_Config();
SystemPower_Config();
MX_GPIO_PE1_Init();
while (1) {
HAL_GPIO_WritePin(LED1_GPIO_Port, LED1_Pin, GPIO_PIN_SET);
HAL_Delay(500);
HAL_GPIO_WritePin(LED1_GPIO_Port, LED1_Pin, GPIO_PIN_RESET);
HAL_Delay(500);
}
}
