器件型号：CC1125

工具与软件：

我目前从事 CC1125的驱动程序开发工作。我尝试通过 SPI 接口在 PSoC6微控制器和 CC1125之间建立通信。我已经浏览过 CC1125的数据表和用户指南、从这里我知道了校准序列。我了解了用于设置 CC1125各种模式(即空闲、睡眠、发送和接收模式)的寄存器、有一些寄存器可以从一种模式切换到另一种模式。我已经测试了 SPI 代码、它运行良好。但是、当我尝试通过 SPI 发送0x8F 来获取器件型号时、无法获取 CC1125的器件型号、该值为0x58。我将发送寄存器地址作为指令、它是1个字节。在访问和读回寄存器时是否还需要注意其他事项？请指派您团队中能够支持我的任何人来启动 CC1125、谢谢。请考虑我的担忧。

尊敬的 Arathi：

器件型号寄存器位于扩展寄存器空间中。您是否首先发送设置了 R 位的0x2F、然后是器件型号地址(0x8F)？

感谢您的答复。我需要获得器件型号、因此我将设置 R 位。我将发送两个字节的数据、其中第一个字节是0x2F 且设置了 R 位、即0xAF、第二个字节是访问器件型号0x8F 的地址。我们使用专门针对 PSOC6微控制器的"cyhal_spi_transfer"函数、同时发送这两个字节。但是、我们无法获得准确的器件型号值。我特此附上调试结果和测试设置的快照。此外、我还要附加 SPI 代码。请回顾并帮助我解决此问题。

期待您的答复。
