In RA smart Configurator, uart stack option cannot be generated, and uart stack can be added manually, only starting from uart0, uart1 cannot be configured as needed

In RA smart Configurator, why I completed the settings of SCI1 and ports in the pins option, but the uart configuration item does not appear in the stack option.

  • Refer to the GPT section of the RA2L1 User's Hardware Manual, section 20.

    Section, 20.3.1.2 , basic operation should give you an indication of what is happening.  For example:

    This diagram shows the GPT counting up, and resetting its count value on overflow, or at GTPR (period value) At this point the GPT can generate an event - GPT COUNTER OVERFLOW.  As the counter counts up, the count value is compared with the value in the GTCCRA ( Compare Capture Register A)  If a compare match occurs, an event can be generated - GPT CAPTURE COMPARE)

    It is via these overflows & compare matches that the GPT can generate output waveforms, and it enabled, interrupts.

  • OK, I See , Thank you Richard.
    And then, i have another problem  about VEE on flash, why the Reflesh Buffer Size is 32, but the API for writing VEE is 8bit ? 

  • When a sector becomes full of records, the most recent record for each ID is copied to the next sector. Then that sector becomes the active sector for writing until it fills up. The copying process, referred to as sector refresh, requires a buffer for transferring records. For the most efficient transfer, the buffer should be large enough to hold the largest record including its header and trailer. The default size is 32. This constant is only modified by advanced users who may need to optimize RAM usage or refresh time.

  • OK ,thank you very much. 

  • Hi czh, 

    Just following up, is this issue solved already? If yes we will mark this thread as solved. Thank you.
