Hello, I am thinking to use RA2A1 MCU to measure a very small AC (50Hz) signal, perhaps millivolt range or lower, but it’s sin wave that has negative amplitude, is RA2A1 MCU single-end input can handle negative signal? Thank You

Hello, You need to go to the" Clocks" tab of the FSP configurator and enable the UCLK clock. also, adjust your PLL Mul and UCLK Div to reach the UCLK frequency of 48 MHz. Kind regards,

Hello,
I am experimenting with UART, I’m transferring data every 1 second in my application. When I connect the Rx and Tx pins there’s no trouble.
But when I cut the pin attachments. The data I send comes back to me in the form of an interruption. How can I fix this situation? What’s the reason for this situation?
Thanks

Hi, Thanks for reaching out to Volt.Tech Engineering Community. The UART- related interrupts can be seen below and call the defined callback function if it's defined. If you do not want a break in you can disable it by configuring SCR( Serial Control Register) properly. Else, you can close UART withRead more
Hi,
Thanks for reaching out to Volt.Tech Engineering Community.
The UART- related interrupts can be seen below and call the defined callback function if it’s defined.
If you do not want a break in you can disable it by configuring SCR( Serial Control Register) properly. Else, you can close UART withR_SCI_UART_Close() when no physical connection is established between the pins and open it again when there’s a connection.
Let us know if you solved your issue.

Hello, guys.
I’m working with the RA6T1 chip, and now my application needs to save some data to flash when powered off and read it when power on.
For now, 8k bytes is enough, so I want to use one code flash block to do it.
But I’m worried about the time because perhaps erasing code flash and programming one block takes 50 – 60ms, now I use LVD to check power voltage, and will erase and program flash when power force drop-down 2.99 V, my question is what voltage is the power drop to, the chip will stop work(erase and program flash), I didn’t get this information according to the manual. Thanks a lot.
Read lessHi, Thanks for reaching out to Volt.Tech Engineering Community. As stated in 41.15.5 of the flash section, the operating voltage range (VCC2.7 to3.6 V for RA6T1) should be within the allowed range. Let us know if it helps.

I have noticed that e2studio uses the term “simple SPI” for the SCI peripherals. I am setting up a new board where I need two SPI connections for my RA4M3 board. One to some motor drivers and one to non-QSPI external flash. I will use the one “standalone SPI” that is available, and then one of the SCI peripherals.
Are there any constraints I need to worry about?

The "simple SPI" mode of the SCI is significantly different than the SPI peripheral. For example the simple-SPI is limited to only 8-databits while the standalone-SPI supports many different bit lengths. If your needs are met by what the simple-SPI supports there is no reason to avoid to using it.

Hi, Please check your below pin / connection is ok. 1. SWCLK 2. SWDIO 3. 3.3V 4. GND 5. RESET need pulled up and give small filter capacitor. 6. MD, need this pin as pullup. Please check this above pins and let me know if you have face any issues. Thanks & Regards Shivali Singh

Is there any binary compression solutions in the FSP? Something like BZ2, LZ4, LZMA, Z standard, Heatshrink or CRLE compression?

Read lessNo - there are not compression APIs included with the FSP. There are many open source compression libraries that you can add to your FSP project.

I am not sure if this is possible with smart configurator but with the latest Eclipse CDT, it is possible to add/remove the nature of the project. Then you can convert to C++. Try searching about using eclipse to convert C projects to C++ project.
