Two registers, STAT_CBUFF_REG0 and STAT_CBUFF_REG1,are used for interrupt status storage. STAT_CBUFF_REG0 has its corresponding clear register CLR_CBUFF_REG0, while no dedicated CLR_CBUFF_REG1 is provided for STAT_CBUFF_REG1, I would like to know how to clear the status bits inside STAT_CBUFF_REG1. I have also downloaded the mmWave‑SDK firmware package. I checked the CBUFF register definition files within the SDK, and there is no CLR_CBUFF_REG1 defined there either.数据通信模块AWR1443https://e2echina.ti.com/support/sensors/f/sensors-forum/1090898/awr2944-awr2944-mcan-tx-buffer-cancellation-txbcr-txbcf-never-completes-when-cccr-init-is-set-while-a-transmission-attempt-is-in-progress-ecu-hangs-in-can_mcanstop/3928259Wed, 26 Aug 2026 03:39:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:cc288795-a35f-4d9f-9f2e-e4ed1eacb85aKen ZhangHi AWR2944 MCAN fully follows the behavior described in BOSCH MCAN_USER_MANUAL mcan_users_manual_v331.pdf Pls refer to above user guide to acquire more information. Also, I would suggest completion of current on-going frame and disable all the MCAN interrupts before any warm reset of AWR2944 or MCAN IP. Many customers suffered from this issue because they failed to execute above advice when jumping from SBL to APP.(which is similar to warm reset of device or MCAN IP) Thanks Kenhttps://e2echina.ti.com/support/sensors/f/sensors-forum/1091136/awr1843aopevm-awr1843aopevm/3928041Wed, 26 Aug 2026 01:13:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:9908fb2e-1906-473b-8aa8-eaa2c8908d3aFRANK1你参考下面2个debug文件，排查下。 e2echina.ti.com/.../8422.DCA1000-Debugging-Handbook.pdf e2echina.ti.com/.../DCA1000_5F00_Debug_5F00_handbook.pdfhttps://e2echina.ti.com/support/sensors/f/sensors-forum/1091118/lm335a/3927231Tue, 25 Aug 2026 08:21:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:f723cdf7-8374-47c2-a889-25e992c79e34Links不能仅凭出现0～2V反向电压判定器件损坏。 LM335A正常工作时本身就是反向偏置，25°C、1mA条件下输出应为 2.95～3.01V。 建议用 5V电源串联2kΩ电阻复测： 输出2.95～3.01V：正常； 输出仍为0～2V：判定为不良品。https://e2echina.ti.com/support/sensors/f/sensors-forum/1091129/tmag5170-tmag5170/3927200Tue, 25 Aug 2026 00:21:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:a250aedf-6a7b-408c-bf67-1785aec6a9b3Daniel您好 TMAG5170-Q1: SPI Communication - Sensors forum - Sensors - TI E2E support forums 请您参考这个帖子对于SPI的相关说明。https://e2echina.ti.com/support/sensors/f/sensors-forum/1091104/tmag5273-tmag5273a1/3927199Tue, 25 Aug 2026 00:09:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:14abfff0-0696-44c7-8156-584c3b65ceb5Daniel您好 [quote userid="182447" url="~/support/sensors/f/sensors-forum/1091104/tmag5273-tmag5273a1"]有什么方法能够精确检测磁铁的所在位置和位移量[/quote] 针对您的问题没有针对性的指导文档，但是存在相关文档和资料如下请您参考。 https://www.ti.com.cn/cn/lit/pdf/ZHCABA4 https://www.ti.com.cn/cn/lit/pdf/ZHCAE25 https://www.ti.com.cn/cn/lit/pdf/ZHCABW9 https://www.ti.com.cn/cn/lit/pdf/ZHCACN7 https://www.ti.com.cn/cn/lit/pdf/ZHCABW6 https://www.ti.com.cn/lit/pdf/SLYT826 以及相关参考设计和辅助计算工具 https://www.ti.com.cn/tool/cn/TIDA-010950 https://www.ti.com.cn/tool/cn/TIDA-060045 https://www.ti.com.cn/tool/cn/download/HALL-PROXIMITY-DESIGN www.ti.com.cn/.../SBAR012https://e2echina.ti.com/support/sensors/f/sensors-forum/1091136/awr1843aopevm-awr1843aopevm/3927192Mon, 24 Aug 2026 22:52:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:4d34d224-d8d9-4da2-80e2-c83ba2a21458FRANK1感谢您对TI产品的关注！ 关于你的咨询，我们正在确认您的问题，感谢您的耐心等待。https://e2echina.ti.com/support/sensors/f/sensors-forum/1091136/awr1843aopevm-awr1843aopevmMon, 24 Aug 2026 12:34:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:deecfaad-1eeb-4a42-88fd-9df3af9f7eb3longlong maPart Number: AWR1843AOPEVM Other Parts Discussed in Thread: DCA1000EVM , AWR1843AOPEVM 通过 mmWave Studio 和 DCA1000EVM 连接失败 我确认了我的设置 和网络服务器设置都与 与 用户手册中的保持一致,PC也能正确读取 设备串口,但是就是无法在 mmWave Studio 中连接 这个是错误代码!
