    Hi Alex,

    The FSP and SSP releases are at a different meter and each version released is tested/ qualified against a specific version of e2-studio. The distribution download of the platform installer will ensure that the proper version of e2-studio will be with the FSP/ SSP version. I advise that you command a different and specific installation for SSP and FSP.

    Thanks & Regards

    Hello,

    By default, all GPIO pins start out at reset as Analog_HiZ. This means the pin though configured at initialization as a draw-down thing inactive low launches life floating until the boot initialization is complete.

    still, also I suggest an average worth resistor( 100K?) drag-down to GND If this is your project case.

    Thank You

    Hi,

    out of my one experience in switch mode power supplies there are a couple of key points to follow when doing these designs.

    1. Insure all resistors are 1 type, this limits the change over temperature which in turn will limit the output change variations.

    2. Insure the track from the switching point is close as possible to the coil and doesn’t add resistance to the coil.

    3. Output capacitors require to hold a low ESR type

    hope some of this helps.

    Thanks & Regards

    Hi, Do all possible noise sources have to be enabled during purposeful radiator testing or just those directly coupled to the antenna?

    Hi, Do all possible noise sources have to be enabled during purposeful radiator testing or just those directly coupled to the antenna? Obviously, there is some possibility of dealings between purposeful and unintentional radiator sources. This is how we get stuff like FCC complete modular instrument taking rf shielding and internal regulation. The unintentional radiator sources would be tested independently with purposeful radiators powered off. This may be different from other official authorities.

    Obviously, espressif should give some support similar to allowing gpio control or Lua/upython scripting in the test binary or releasing a library that can be incorporated into IDF designs. perhaps too important fear of CW mode being turned into a jammer? At least it should be available under NDA and usage agreement.

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

    Hi, If you have a DC-coupled Current inquiry you can cover Inductor Current to check if it isn't working in the saturation region. Still, also you can check the switching pin with a voltage inquiry just to see a perfect waveform and measure the right switching frequency. Let me know. Nidhi Singh

    Hello,

    Thanks for sharing your question with Volt Engineering Community!
    Please take a look at Code written for downloading and debugging with E2 will most likely just hang when run without a debugger attached.

    1. RFP is an option, or any development environment such as e2 studio or 3rd party tools can program the flash of the device.
    2. No special accommodations in the application code are necessary to enable flashing the device. Most designs will incorporate a custom charge-loader that uses a particular interface (UART, CAN, etc.) with a proprietary comm protocol, but this isn’t needed if the serial programming mode of the device can be set and a tool used that supports factory programming protocol.
    3. Renesas devices are optimized to execute code from the flash. Some designs that use comparatively slow flash technology can profit from RAM execution but that isn’t the case for RA devices.

    Kind Regards,
    Vikas Nagpal
