Category: Microcontroller

A microcontroller is a compact integrated circuit designed to govern a specific operation in an embedded system. A typical microcontroller includes a processor, memory and input/output (I/O) peripherals on a single chip. Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general purpose applications consisting of various discrete chips. The general microcontroller consists of the processor, the memory (RAM, ROM, EPROM), Serial ports, peripherals (timers, counters), etc. You may find your solutions or share your thought about to microcontroller by using our Volt.Tech support forums that are supported by thousands of contributing Volt.Tech experts.

Hello everyone. I’m trying to use a driver that uses spi with my RA6M3 board. But I ran into a problem that I had not encountered ahead. The NMI interrupt goes into an infinite loop and doesn’t live. I do not know much about NMI so I do not know what to do. The NMI pin on the RA6M3 board is P200. P200 isn’t enabled but never gets stuck in NMI masking function in the spi_transmit process. And it can not exit NMI_Handler.

Thank You

    Hello, What's the value of the NMISR register when the NMI handler is called? The value of the register gives some data about the cause of the NMI interrupt. Also at what point inside the 'spi_transmit' does the NMI occur? Regards Alex Thomas

Hello,

I could not discover the position of the electronic components in the blue circle in the schematic diagram in the AN599 Radar Baseboard MCU7- XENSIV ™ 60 GHz radar system platform file. What should I do to understand who these electronic components are connected to?

    Hi @Julian You can get an overview of the Radar Baseboard MCU7 schematics, and Altium design to have further insight into these components' connection. You need only to download the Radar Development Kit and browse the Hardware section. Cheers, Nidhi

Hello. I have the RA6M3 development board. With this card, I want to save the HDMI image to an SD card or USB flash, and at the same time, I want to display it on the LCD screen. Two styles come to mind. Which makes further sense?

1) First method, I can convert it to HDMI to the serial camera interface, control it with PDC, print to LCD screen, and save it to flash. How do I convert from HDMI to serial camera interface if I do this?

2) second method I’ll convert from HDMI to USB, save it to flash, and show it on the LCD screen.

Which of the 2 methods I mentioned over would be more straightforward and more logical? Are these methods doable? What do you suppose will be the quality of the video I’ll record in the most applicable method? Can I record 1080P 60 FPS? I would be very thankful if you could help me with your experience. Thank you very much for your support.

Have a nice day.
Enjoy your work.

Hello Forum,

I am trying to collect and run the NetX_dhcpv4_client project from the r20an0585eu0127– ek- ra6m4 example projects.zip group of demo projects. I’ve what I suppose is a standard install of the FSP4.3.0 decline and toolchain. If I import the below project from the zip file it looks like it imports clean but will not compile. I’m getting the error saying the toolchain configured for the project isn’t presently available. Where have I gone wrong with this project importation? I would have allowed all these example projects to be set up to run on the default toolchain.

Thank you for the help!!

Hello,

Using a single wdg at the driver position and 2 wdgm cases at the service layer position also can monitor both CPU0 and CPU1, right?

Then why different watchdogs are available in the TC3XX family? Is it due to any safety medium?

Whether using a single wdg (CPU0WDG) can make any safety violations?

    Well, that good olde L293D. This is a no-brainer because even a 3.3 V supplied GPIO affair generates 5V TTL compatible signal situations. See the datasheet of your chip. Application note AN4899" STM32 microcontroller GPIO hardware settings." is worth reading.

Hello Forum,

It’s been 5 years since I’ve done important firmware and have forgotten a lot of how this device works. I am trying to learn a simple netx application running. In the older Community ssp, there use to be a tab like properties or something that would allow me to change things like the thread name and set the heap and stack sizes. Where is that now hidden? I allowed it use to be down in the lower section there next to the problems tab.

Thank you for the help!

Dear colleague,

I’m working on a design where I’m applying the CY8CKIT- 062 PIONEER KIT, my design is versioned and everything is working OK (compilation, libraries, BSP) until I changed my laptop.

I pulled the design from the server to continue solving (understanding that Ire-generated themtb_shared libs using the library director) and the problem of the unresolved inclusion’ starts just after that. I tried to fix this using the indexer update and so on but I require help finding something!

Another thing that I need to mention here’s that when I produce a new design based on the empty design template’ the same problem occurs.

Thank you for your help.

    Hi Nidhi,

    I’ve just set up a result for this problem and I wanted to share it with you (if you or anyone differently have the same problem).

    On the top menu bar, go to Project-> Properties
    A properties window will show. On the left side menu, go to Project References.
    On the box to the right, confirm if other systems are listed and check the ones that might be related to yours.
    Press Apply and Close buttons.

Hi,

I need to apply the virtual EEPROM on a RA2E1. In principle, this mechanism works, and I can write and read the record IDs. During the production of the board, I need to program the original content of this rec id. Is there any documentation or example on how to make the memory address’s binary file starting from 0x40100000?

    Hi Nidhi,

    Thanks for reaching out to Volt.Tech Engineering Community.

    If I understand right you need to program the data flash of the device just right?
    The data flash can be written in both ways, by Renesas Flash Programmer, or by self-programming (by the software running on the device).

    To program only the data flash with Renesas Flash Programmer, the file used to program the device would require to hold only data for the data flash address range. A. srec,. hex, or. bin file can be used with RFP to give the data to be programmed into the flash.

Hello, I am planning to use RA2A1 MCU for a design with 24-bit ADC sampling and relay control.

Because there are many 5V peripherals in this system, it’ll be much simple if the RA2A1 runs at a 5 Volt power supply.

Most of the RA2A1 examples are running at a 3.3 V power supply, what’s the potential problem if run at a 5 V power supply?
