        baz doo | 04/115/2018 | 06:19 AM

        The Si4713 output amplitude is programmable from 88dBuV to 120dBuV,but  when I use the field intensity meter to measure the power can't be more than 100dbuv  .I want to know how measure it.

      • AMW037 boot error

        Alan Graves | 04/115/2018 | 03:32 AM

        I have a module from Digikey that doesn't display anything on the UART_TX pin 11 like I was expecting, it does however boots up with a serial message that is output on pin 31 which is GPIO_7 (or alternate function UART_RTS).

        The following message is output:

        ets Jan  8 2013,rst cause:1, boot mode:(2,7)

        Fatal exception (0):
        epc1=0x40100000, epc2=0x00000000, epc3=0x00000000, excvaddr=0x00000000, depc=0x00000000
        Fatal exception (0):
        epc1=0x40100000, epc2=0x00000000, epc3=0x00000000, excvaddr=0x00000000, depc=0x00000000
        Fatal exception (0):
        ...
         
        Any idea how to fix this problem?
        It appears that a boot loader is unable to find or execute the appropriate firmware image and repeatedly throws an exception.
         
        Thanks,
        ALan

      • SLSTK2000A SMBus library questoin

        Kevin Chen | 04/114/2018 | 10:36 PM

        Hi all,

        I am using the starter kit  (SLSTK2000A) for some smbus tests.

        There is an example "EFM8UB1_SMBus_Lib_Buffered_Master_Multibyte" for smbus.

        I found when I compiled this project, there is nothing wrong, no warning, no error.

        But, the smb_0.c file will show a red cross mark on it.

        And two functions have some indication message :

                  SI_REENTRANT_FUNCTION(SMB0_getStatusFlag, uint8_t, (uint8_t flag))

                  SI_REENTRANT_FUNCTION(SMB0_setStatusFlag, void, (uint8_t flag, uint8_t state))

         

        Is there anything I can do to eliminate these abnormal message ?

        Thanks,

      • Register map and bitfiels for Radio Controller of EFR32MG12P332, information not found

        Grégory Emery | 04/114/2018 | 01:43 PM

        Hello everyone,

        I am searching for information about the radio controller register interface of the efr32mg12p332f1024gl125. After a rough reading of the reference manual, it seems there is no register description in this document. I've found static libraries for interfacing with the radio module, but not a single register address or bitfield description. So my question is : is this information available anywhere? And in the case it is, can you show me the location? Because I am searching for it since 4 or 5 hours... (-__-)

        The goal is for me to use Rust to implement a firmware for the Thunderboard Sense 2. And the project includes a radio communication stack. Linking against a static library written in C is really not the goal of this project.

        Thanks for your answers

        Grégory
