这里登记NRF52832DK使用过程中遇到的各种问题。
1 支持哪些仿真器？
支持的仿真器有：
- 谷雨Jlink-Lite仿真器，10pin接口，与NRF52832DK完全匹配可直连。
- 标准Jlink仿真器，20pin接口，无法与52DK直连，需要转接，可选购我们的Jlink适配转接板。
2 支持哪些显示屏？
支持的显示屏有，意思是硬件接口和软件驱动均支持的。
- 谷雨1.44寸TFT彩色液晶屏，128x128分辨率。
- 谷雨1.32寸TFT彩色液晶屏
- 谷雨1.54寸ePaper电子墨水屏，200x200分辨率。
3 安卓或iOS的App源码？
Nordic开源非常多的ble应用的代码，包括nRF Connect和nRF ToolBox，源码托管在Nordic官网Github，另外还包括很多其他平台的相关代码，具有非常大的使用价值。
