Hello,

Three accompanied PWM waveforms

Is there a recommended way of producing three accompanied PWM waveforms on an RA4M1?
Two is easy with the two outputs from one counter, but how about three?

Should I start two counters together, and hope for the best?
Should I set one to count to a higher figure, and also use the second one to reset the first?

Thank You

    Hello @ashish To read the advertising name and data of other devices, you will need to use the Bluetooth Low Energy (BLE) scanning feature of your RA4W1 evaluation kit. This feature allows your device to scan for nearby BLE devices and retrieve their advertising data. Thank You Jullian White

Hi all,

I am testing to configure node 2 and node 3 on module CAN1 to be linked to the inside can bus and out.

My final aim is to transfer some data on cun node 1- 2 and receive it on can nodes 1- 3 without any processing in the CPU.

no purifier configuration and messages to be transferred, no pack/ unpack function- just as simple as that loop back out.

so I set all needed configurations where I had the node working on normal mode( transfer and receive messages, filter, and messages defined), but also I removed the configurations of the filter and added to the configuration the needed flag

rc = canNodeConfig (& nodeConfig, reeCanNode);// set common configurations

* nodeSfr = IfxCan_getNodePointer (nodeConfig.can,nodeConfig.nodeId); nodeSfr->NPCR.B.LOUT = 1;

for both nodes 1- 2 and 1- 3.

what eventually happens is that I send from an outside source and it looks like the CPU receives (no errors on the bus) but the other bus has errors on it.

how can I be sure that the messages entered into that node? will interrupt for TX/RX receive?
what should I do to test it correctly?
is the setup OK for my purpose? (loop back out)?

Thank You

    Hello,

    Connected to the internal CAN bus and loop back the messages received on node 2 to node 3 without any further processing by the CPU.

    To accomplish this, you can configure both nodes to operate in normal mode and enable loopback mode for node 2 using the LBP bit in the NPCR register. The LBP bit sets the loopback mode for the node, allowing it to receive its own transmitted messages.

    Here are the steps you can follow:

    • Configure both nodes to operate in normal mode as you have already done.
    • Enable loopback mode for node 2 by setting the LBP bit in the NPCR register to 1.
    • Transmit a message from an external source to node 2.
    • Verify that node 2 receives the message by checking the RMC and NCR registers.
    • Verify that node 3 receives the same message by checking the RMC and NCR registers.

    You can also use interrupts to receive messages on the nodes. You can enable interrupts for receive and transmit events and write interrupt service routines (ISRs) to handle the events. When a message is received, the corresponding receive interrupt will be triggered, and the data can be read from the received message object.

    Kind Regards,

    Alex Thomas

Hello,

I am setting up the two interrupts on the LSM6DSOX, INT1, and INT2 to indicate Single and Double Tap events, independently.

I am suitable to make both events spark their separate interruptions but I would want them to be fully separate.

I suppose I need to apply a delay on the Single Tap, to insure it does not operate under double tap condition- it presently works twice for a double tap!

Is there a way I can do this inside the LSM6DSO, or must I separate the interrupts in my microcontroller?

Thank You

    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,

I’m trying to come up with a system to perform wear leveling in the Dflash EEPROM (AURIX TC265).

After going through the user manual, example code, and a few other posts in this forum, the correct way of writing to Dflash is (Please correct this if it’s wrong)

1. Erase entire sector( 8KB)

2. Enter Page mode with the page address

3. Load data to be written

4. Write page/ write burst.

Repeat steps 3 and 4 until the needed amount of data is written to DFlash.

The data that I want to write to Dflash isn’t further than 32 bytes in total. So, I was looking for a technique to spread out these 32 bytes written in the logical sector( 8192 bytes) itself every time I need to store a new dataset. Is this possible? Or am I limited to spreading out my writes across sectors and not on the page level, as erase command works only on the sector level and not on the page level?

Thanks

    Hi Vikas. Yes, that is a common issue. You do not need to fill the whole sector at once; you can incrementally write pages until the industry is full.

    Hi Vikas.

    Yes, that is a common issue. You do not need to fill the whole sector at once; you can incrementally write pages until the industry is full.

    The tricky part is avoiding the erase disturb effect and dealing with the possibility of word line failures, as described in 10.8.3.1 Robust EEPROM Emulation on page 1000 of tc26xB_um_v1.3.pdf. For example, it’s impossible to have one set of static manufacturing data written once in DF0, and one set of dynamic data; all data must be periodically rewritten to avoid erasing disturbs.
