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

Hey, I am creating a smash barrier controller with ESP32 SX1276 LoRa microcontroller, and I require a 5V external power force, but I can not find anywhere which pin of 5V is the VIN one, I do not want to ruin my module, so does anyone know this particular module and which of the 5V pins is the VIN one? I have uploaded the board setup for reference purposes. If you want any extra information please let me know.

    Hello, They are likely both connected to the Vin signal; check with a multimeter if there is continuance between the two pins if you want to make sure. Thank You Nidhi Singh

    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.

Hii, It’s getting as far as setting NEWDATA in MCTL_RX (also sets MGSLOST, presumably when the coming message arrives). It also sets NDST in STR.

An acknowledged pulse is transmitted on CTX. So, I presume the filters are set correctly.

STR isn’t in HALT or RESET. The relevant bit is set in MIER.

is set to 0x4D, but bit 16 (IR) remains clear. The interrupt handler routine is never invoked. ISER0 bit 0 is set.

Other interrupts are working (RTC). Is there some other global interrupt enabled within the CAN module that I’ve overlooked?

    Hi, The FSP documentation includes examples of using AES encryption and decryption. For a PC- based tool, I would suggest putting something together using Python. The Security Key Management Tool is used for installing/ wrapping keys and so isn't the device you need for the application you describe.Read more

Hi,

Configured IRQ Control Register (IRQCRi) rising and falling edge discovery (IRQMD{10}).
When the interrupt of the edge discovery is raised, where to find out which edge falling or rising is detected, I need to know what’s the pin position of the GPIO input pin when an edge is detected.

The used CPU is RA2E1.

    Thanks for posting your question!

    You could check your IRQ- pin’s level when entering your interrupt message function in order to check if a rising or falling edge is detected. In case your pin’s level was initially low and when entering your message function it became high then a rising edge was detected. If your pin was initially high and also became low then a falling edge was detected. You could read your pin level by accessing the register shown in the picture below.

    For example, if your IRQ pin is P110, you could check its level in the interrupt message function like this:
    R_PORT1->PIDR_b. PIDR10 and check if it’s 1 (HIGH) or 0 (LOW).

    Another way is by using the already given API
    1.fsp_err_tR_IOPORT_PinRead(ioport_ctrl_t * constp_ctrl,bsp_io_port_pin_t pin,bsp_io_level_t *p_pin_value);

    Kind Regards,
    Alex
