    Hi Pensive,

    well, if you need only a few (short) sounds, that could fit to flash, there is no need in external socket + SD card.

    Hi jcarruthers,

    the flash memory is in the common address space! So, when you do
    uint32_t nVar = *(uint32_t*)0x00008000;
    statement, you read from P-flash the 4 bytes from 32kB offset. You...

    Problem solved!

    Happy to report that the error was in the poor battery connector soldering. So, the RTC in Teensy seems to be stable :-)

    Internal RTC reliability?

    Hi all,

    our project highly depends on RTC. We added a battery to teensy 3.1 to get internal clock running during power outages. Usually it's powered from USB.

    We have two items in field running...

    Hi again,

    even if nobody replied my post ;-) here some I hope useful info about internal flash for Teensy 3.1 (MK20 CPU actually).

    So, first of all, there are 2 types of the flash memory there:...

    Sorry Paul, and how to clear EEPROM every time when I upload the code? use v1.19...

    Hi all,

    not sure if it's interesting for somebody, I followed Michael Meissner's suggestion to use -ffunction-sections -fdata-sections, and then pass --gc-sections to the linker.

  13. Teensy 3.1 - ability to use internal flash for logging?

    Hello,

    before I start to dig in to the MCU pdf, can anyone assure me that the following is possible at all?

    1. If my code uses let say 25% of flash, can I use the rest of it as a sort of NVRAM?...
