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.

  • Which version of the FSP are you using? Which RA device are you using? Which version of e2studio or the RASC are you using?

  • Jeremy, please tell my why, it is my first time to use RA2L1 series MCU, we will use this series MCU in thefuture. Thank you very much.

  • I have no problem adding the UART driver and setting the channel to 1 using RASC 2021-04 with FSP 3.1.0 :- 

  • Yes, maybe I know why I can not to do it, I am not very familiar with RASC yet. It can choose which channel and then it will be fine.Thank you Jeremy. Best wish.

  • Hi Jeremy, need your help, when add uart1 stack and then generate project content, when i built in keil, a error occured as following picture.Do you know what is the meaning? user_uart_callback it should be redefine and implement by user?

  • The user has to create the callback function user_uart_callback

  • Hi Jeremy, I want to ask for you something about GPT. What are the meaning of these two event.

  • 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 ?
