Both I2C instances run at 100kHz. When the I2C1 bus experiences a fault (e.g., slave holds SCL low, or a hot-plug glitch), my error recovery performs: I2C_close(i2cHandle); i2cClearBus(); // GPIO bit-bang: 9 SCL pulses + STOP condition i2cHandle = I2C_open(CONFIG_I2C_0, &i2cParams); I2C_setClockTimeout(i2cHandle, ...); After this sequence, I2C_open() returns a non-NULL handle (success), and I2C_transfer() returns true (transfer queued). But the transfer callback never fires. The ISR ( I2C1_IRQHandler ) appears to stop triggering entirely. Every subsequent transfer times out the same way — I2C_transfer() returns true, but the callback never runs, even for transactions where the slave ACKs its address. hdd_i2c_payload_manager.c ti_msp_dl_config.c i2c_controller.c ti_drivers_config.c工业自动化MSPM0G3507https://e2echina.ti.com/support/microcontrollers/msp430/f/msp-low-power-microcontroller-forum/1074473/msp430fr6047/3876463Wed, 03 Jun 2026 06:04:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:562e79f6-f34c-4b96-93ff-0bb430a9f4ebLT1 Shen1e2echina.ti.com/.../3603.USS_5F00_userConfig.hhttps://e2echina.ti.com/support/microcontrollers/msp430/f/msp-low-power-microcontroller-forum/1074473/msp430fr6047/3876462Wed, 03 Jun 2026 06:03:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:c902ea4f-a22a-480a-8365-69aa5b936107LT1 Shen1您好！ 感谢您的回复，是的，我仅更换了.h文件，甚至我仅更改.h文件中的频率，依然会导致此现象。https://e2echina.ti.com/support/microcontrollers/msp430/f/msp-low-power-microcontroller-forum/1074473/msp430fr6047/3876461Wed, 03 Jun 2026 05:58:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:c5f16978-bd24-48c7-8022-db3541d8dde0Peter Jiang你好， 能否请您也上传一下您使用 2MHz 传感器时的文件？我也想看一下。另外，您之前在使用 1MHz 传感器时遇到过无液体情况下的卡顿问题，而使用 2MHz 传感器时没有出现这个问题。这两个传感器之间的唯一区别是否仅仅是您更换了传感器并修改了 userConfig.h 文件？您还做了哪些其他修改？ 此致， 彼得ECTEhttps://e2echina.ti.com/support/microcontrollers/msp430/f/msp-low-power-microcontroller-forum/1074473/msp430fr6047/3876358Tue, 02 Jun 2026 07:24:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:24f7d666-12ca-40a4-8db3-b8187c70eb03LT1 Shen1e2echina.ti.com/.../4274.USS_5F00_userConfig.hhttps://e2echina.ti.com/support/microcontrollers/msp430/f/msp-low-power-microcontroller-forum/1074473/msp430fr6047/3876357Tue, 02 Jun 2026 07:23:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:79f8fbcb-b4cb-4daf-a691-3ffd0bc2af38LT1 Shen1您好！ 首先，感谢您的回复，我的USS_userConfig.h文件，是通过USS软件生成的，是我使用MSP430FR6047评估板搭配结构所采取的配置。我想将其复制发出来，但不知道为什么，添加后回复时，论坛显示出现错误。https://e2echina.ti.com/support/microcontrollers/msp430/f/msp-low-power-microcontroller-forum/1074473/msp430fr6047/3876346Tue, 02 Jun 2026 06:25:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:faecf85a-d3eb-4560-83ff-4aa817b172faPeter Jiang你好， 你比较过图形用户界面生成的文件和你的项目文件吗？它们之间有什么区别？或者你可以上传相关的配置文件（.h 文件），我可以看一下。 此致， 彼得ECTEhttps://e2echina.ti.com/support/microcontrollers/msp430/f/msp-low-power-microcontroller-forum/1074473/msp430fr6047/3876316Tue, 02 Jun 2026 02:20:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:5a51168d-b145-4080-ac74-31e4103562d5Xiaodong LI我们会尽快找到专家来协助您。ECTEhttps://e2echina.ti.com/support/microcontrollers/msp430/f/msp-low-power-microcontroller-forum/1074473/msp430fr6047/3876313Tue, 02 Jun 2026 02:05:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:e41bcd1a-66af-4a98-b2af-f4f7d105abf9Xiaodong LI我们会尽快找到专家来协助您。ECTEhttps://e2echina.ti.com/support/microcontrollers/msp430/f/msp-low-power-microcontroller-forum/1074473/msp430fr6047/3876237Mon, 01 Jun 2026 05:01:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:01532dce-6c19-451b-a35b-dccffe02bc10Links您好， 已经收到了您的案例，调查需要些时间，感谢您的耐心等待 。 TRANSLATE with x English Arabic Hebrew Polish Bulgarian Hindi Portuguese Catalan Hmong Daw Romanian Chinese Simplified Hungarian Russian Chinese Traditional Indonesian Slovak Czech Italian Slovenian Danish Japanese Spanish Dutch Klingon Swedish English Korean Thai Estonian Latvian Turkish Finnish Lithuanian Ukrainian French Malay Urdu German Maltese Vietnamese Greek Norwegian Welsh Haitian Creole Persian TRANSLATE with COPY THE URL BELOW Back EMBED THE SNIPPET BELOW IN YOUR SITE Enable collaborative features and customize widget: Bing Webmaster Portal Backhttps://e2echina.ti.com/support/microcontrollers/msp430/f/msp-low-power-microcontroller-forum/1074473/msp430fr6047/3876236Mon, 01 Jun 2026 03:41:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:cf4a8d8b-926e-4f08-9cbb-52a98a4ccec2LT1 Shen1Memory:0x50f4 USS_SW_Library_configuration systemConfig ussSystemConfig (0x4F16) Memory:0x50f4 USS_System_Configuration * mCLKFrequency 8'000'000 Memory:0x4f16 uint32_t LFXTFrequency 32'768 Memory:0x4f1a uint16_t timerBaseAddress 896 Memory:0x4f1c uint16_t measurementPeriod 983 Memory:0x4f1e uint16_t diagMode USS_diagnostics_mode_2 (2) Memory:0x4f20 USS_diagnostics_mode meterConfig ussMeterConfig (0x4F2E) Memory:0x50f8 USS_Meter_Configuration * volumeScaleFactor 2.701'798'75E+6 Memory:0x4f2e float volumeAddlScaleFactor 1.0 Memory:0x4f32 float acousticLength 70.0 Memory:0x4f36 float transducerFreq 1'000'000 Memory:0x4f3a uint32_t measurementConfig ussMeasurementConfig (0x4F60) Memory:0x50fc USS_Measurement_Configuration * sequenceSelection '.'
