    Hello,

    Thanks for reaching out to Volt Tech Community.

    The acceptance filter of CAN is implemented with 8 acceptance masks (one mask for every four mailboxes). Masks are independently enabled or disabled for each mailbox. This cannot be done with FSP APIs. You can either manually write the Mask Registers (MKRk) (k = 0 to 7) or more easily set the group masks on the FSP configurator:

    The above settings will set the MKR registers automatically:

    How to Get High Speed LED Driver in Different Series?

    Alex thomas
    Added an answer on September 19, 2023 at 11:10 am

    Hello, Right, existing LED drivers all have PWM engines. It depends on the LED, some have Vf = 1.8, and some have 3.5V. So, 15x3.5 = 52.5 V in direct mode. Also current, 20 mA or more? For low current low voltage OPA may be an option, or OPA buffered by transistor for high CV. Thank You

    Hello

    I assume that you’re using our STEVAL_ISC005V1 board and what you call ‘PDO1’ is Vsnk from the schematic.

    However, Vsnk lights are on for all PDOs selections. Whereas PDO2 is ON if PDO2 is selected and PDO3 if PDO3 is selected.

    Our algorithm always tries to select the highest voltage. If the charger is so that PDO3 can be selected, then PDO3 Vsink will light on,

    However, also PDO2 Vsnk will light ON. If the charger is smaller.

    Best regards

    Hello,

    Yes, the ESP32-C3 microcontroller provides access to the low-level RF encoder/decoder functionality for custom transmission and reception on the 2.4 GHz frequency. The ESP32-C3 is equipped with a Wi-Fi/Bluetooth subsystem, but it also supports other communication modes, such as RF communication using the RF module.

    To use the RF module for your application, you would typically need to bypass the higher-level protocols like Wi-Fi and Bluetooth and directly control the RF interface. The ESP32-C3 provides a general-purpose radio (RF) peripheral that can be used for this purpose.

    Thank You

    Hi there,

    You can follow the below steps to reactivate the software license. (Note that you also can use the same procedure to reactivate your kit when this kind of issue happens again)

    Step 1 Use Segger J- Flash Lite to erase the chip.

    Step 2 Use Segger J- Flash Lite to program the corresponding s- record image file. The ZIP file below contains the image file for RA6E1- VUI kit( TW001- VUIA6E1POCZ). zip

    Step 3 Extract the Zip file below to get the CyberonLicenseTool and execute it.

    Software License RecoveryTool.zip

    Step 4 In the tool pane, select the”CybServer_RenesasWWPromo_Recovery. bin”, which is also provided by the above Zip file, in the first configurable window.

    Step 5 Then, fill up the correct UART settings in the second configurable window. You can check out Device Director to get the correct COM port number, which should be assigned to JLink CDC UART Port.

    Step 6 Click the launch button. Then, you should get the communication as same as below.

    Step 7 Press the onboard S2 Reset button( should be a red color button). also, you should get the communication as same as below.
    *** When you find the communication of” License data OK”, the reactivation process is done successfully. ***

    Step 8 Before you close the tool, you can try speaking to the device using Wake- up command” Hey Siri”. Once the program reacts to your voice command, it means the license confirmation process is passed.

    Step 9 Close the license programming tool and reboot your device. After that, you can use Tera Term to test the device.

    NOTE For doing this process, there’s no extra hardware connection needed except the single USB connection between your computer and the onboard micro USB connector J6.

    Thanks,

    Nidhi
