Home/Memories

Category: Memories

A major element of every microcontroller-based embedded system is memory. Memory Card can be defined as a portable electronic storage device that falls under the category of the flash type of storage devices. This device has become a widespread storage method used to match with the modern-day technological evolution. The problem is that non-volatile memory technology options are expanding, making it challenging to determine the right memory for an application. We’ll provide some clarity on where to use each type like Memories, EEPROM, Flash, SSD, eMCP, eMMC, SRAM and their advantages. You may find your solutions or share your thought about to Memory by using our Volt.Tech support forums that are supported by thousands of contributing Volt.Tech experts.

Hello,

I’m working with E2studio 2023-10 (23.10.0) Build Id: R20231006-1456. with FSP 5.0.0

In my project, I have FreeRTOS with some Threads.

In one of these threads, in the header file, I put some declarations of my functions. I think that the correct line to put them should be between declarations of FSP_HEADER and FSP_FOOTER.

But when I compile the code, sometimes this declarations are erased automatically and I get a warning about no declaration of function.

What is the correct way to fulfill this header file?

Thanks. Greetings.

    Hello Kendallsmith,
    Thanks for reaching out Volt Tech Community!
    Is the header file that you tried to add your code, located on the ra_gen folder?
    Still, you can not add code, because the files in this folder are auto-generated, If yes.
    However, please add it inside the src folder, which has been created for the user’s code, If you want to add code.
    Hope it helps!

Dear Team,

I understand the System reset is turned on when SRSTN is set low.
I would like to know the details of the System reset function.

After the System reset,
is the Firmware renewed from the first step?
Can IO status be reset?
are all peripheral functions reset?

Best Regards,

Thank You

    Hi, HIB_REG_ON_IN is applied by the hibernation block to power up or power down the internal CYW43907 controllers.

    Hi,

    HIB_REG_ON_IN is applied by the hibernation block to power up or power down the internal CYW43907 controllers. For applications that use the hibernation block, HIB_REG_ON_OUT must connect to REG_ON. Also, when de-asserted, this pin holds the WLAN and APP sections in reset.

    SRSTn- System reset. This active-low signal resets the backplanes.

    Yes, After reset FW is also reloaded

Hello,

I am trying to put together a design with WROVER and LAN8720A. Based on existing designs similar as the one with WROOM and LAN8720A, GPIO17 is applied as EMAC_CLK_OUT. I wonder if there are any alternate pins for EMAC_CLK_OUT. Since WROVER uses GPIO17 for SPIRAM, if I can not apply a different pin, also I am stuck with WROOM only. It’s good to know what my options are.

Thanks in advance.

    Hello,

    I did this numerous years ago, so I’m still determining what has been modified in the software. But back also you could configure to use GPIO0 as the CLK.
    The problem with this was that it didn’t allow uploading the firmware automatically. You had to manually keep GPIO0 low and reset it to put it in bootloader mode for downloading. I wouldn’t say I liked this approach so I did it this way rather.

    I do not use that design presently, mostly because I only use the ESP32- S3, and there’s no stock of the LAN8720A. When I need Ethernet I use the KSZ8851SNL Ethernet Controller. Works great.

    Thank You

I’m presently in search of an LED driver for one of our products.
Since the LEDs are applied for the stimulation of cells, it’s crucial that the output current of the driver is a real adjustable constant current and not just a high- frequency PWM signal even if the “flickering” is undetectable for the human eye.

Does Volt Tech offer products that give a dimmable constant current output (some noise is of course tolerated)?

Best wishes,
