Hi,I'm working on a hardware design using the STM32F765VIH and I am trying to connect a MT28EW128ABA1HPC-0SIT NOR Flash and IS66WVH16M8DBLL-100B1LI PSRAM to the FMC in muxed mode. I'm struggling to understand how the muxed connection should be made a...

I have this working keras model: https://www.dropbox.com/scl/fi/544ma5tsndw3cjv8djem0/model.keras?rlkey=87845alu8vki9y81kb7tjgrab&dl=1 and I am trying to load it into X-CUBE-AI 8.1.0 When I hit Analyze I get this error: Neural Network Tools for STM3...

I have a custom design using the S2-LP and SE2435L amplifier, largely similar to the STEVAL-FKI915V1. About one year ago we produced a first batch of prototypes and it all worked perfectly on the Sigfox side. Now I am testing a second version prototy...

Hi,I have a custom design based on the S2-LP eval kit, tested my firmware (based on the ST Sigfox Library) with the eval kit and ST's ID/PAC and all is working fine. Custom hardware is also working fine and now I am in the process of installing the p...

Posted on January 16, 2017 at 16:16I've noticed that in the STM8S standard peripheral libraries, in the UART1_Init function there is an assertion checking the baud setting:assert_param(IS_UART1_BAUDRATE_OK(BaudRate));Digging into stm8_uart1.h, the d...

Sorry I had specified the wrong part number for the NOR Flash, I'm considering the MT28EW128ABA1HPC-0SIT but regardless of the actual partnumbers is there any reference design that shows how to interface the muxed FMC to standard parallel NOR Flash o...

Thank you, I tried this and got past that error but now getting the below error, ...am I trying to use a too complex model? Neural Network Tools for STM32 family v1.7.0 (stm.ai v8.1.0-19520) E010(InvalidModelError): Couldn't load Keras model C:\[red...

Posted on January 18, 2017 at 09:54 Thanks Turvey.Clive.002‌ , yeah I think the 10MHz clock case would justify the default 625000 limit but I would have expected this to be based on a check toCLK_GetClockFreq() not a hardcoded limit.

Posted on September 29, 2012 at 11:02Hi Clive,Thanks for the tip on the IAP appnote, No I was not aware of this app note and the example IAP driver source code. I'm relatively new to STM32 and that's why I prefrred to use the inbuilt bootloader rath...

Posted on September 28, 2012 at 17:49Thanks for the replies so far...Yes the USB interface is FTDI (FT232RL) based so in theory yes I can use the DTR or some other pins to select the bootloader option but in practice it is something I would like to ...
