`SLWSTK6021A开发板,自带带数据包追踪接口和虚拟 COM 端口的板载 J-LINK 调试器，可对连接的无线电板和外部硬件进行应用程序开发和调试。

墨水瓶显示JLINK的相关信息。
开发环境为Simplicity Studio，和STM32的IDE STM32CubeProgrammer试用类似。
开发环境搭建可以参考官网如下：

一个工程搭建如下：

开发板的硬件GPIO SCH原理图如下：

IDE具有模拟示波器的功能。板子的功耗可以可视化实时仿真。

分析main函数：

int main(void)
{
// Initialize Silicon Labs device, system, service(s) and protocol stack(s).
// Note that if the kernel is present, processing task(s) will be created by
// this call.
sl_system_init();
// Initialize the application. For example, create periodic timer(s) or
// task(s) if the kernel is present.
app_init();
#if defined(SL_CATALOG_KERNEL_PRESENT)
// Start the kernel. Task(s) created in app_init() will start running.
sl_system_kernel_start();
#else // SL_CATALOG_KERNEL_PRESENT
while (1) {
// Do not remove this call: Silicon Labs components process action routine
// must be called from the super loop.
sl_system_process_action();
// Application process.
app_process_action();
#if defined(SL_CATALOG_POWER_MANAGER_PRESENT)
// Let the CPU go to sleep if the system allows it.
sl_power_manager_sleep();
#endif
}
#endif // SL_CATALOG_KERNEL_PRESENT
}
