In TC377, what's the problem with DMA and CPU access a same SRAM at the same time? For example, during CPU reading a variable DMA moves a data to the variable, or during DMA moving a data to a variable CPU reads it, what will happend in this case?

Hi,

Voltage trackers that I see in Infineon portfolio (for example TLS115B0EJ) are down to 2V (ADJ/OUT).  In my setup LDO input will be 5V, output current under 150mA, and ADJ/OUT should go down to 1.7V. Is it possible for this devices (specified with min 2V ADJ/OUT) to work fine in my setup?

Thank you

J.H.

Hello everybody,

I have some problems to communicate with a 2D hall sensor from Infineon via I2C.

First some background information:

CY8CKIT-42 PSoC 4 Pioneer Kit

PSoC Creator 4.4

TLE493D-A2B6 (https://www.infineon.com/dgdl/Infineon-TLE493D-W2B6-UM-v01_01-UserManual-v01_11-EN.pdf?fileId=5546d46261ff5777016229accba436e2)

I wrote myself two functions which allow me to read or write a register.

The TLE493D has a 2-byte read command and a 1-byte read command. So I try to write the register first and change it to 1-byte read command mode.

When I try to write a register, it works, but when I try to read a register, I always get a NACK after I send the register address of the sensor. I don't know what the problem is.

 

I tried the read function with a MPU6050 sensor and it worked. I could read the register.

Why can't I read the registers properly?

I have added some pics and the project in the attachment.

 

Best Regards and Thank You

What does each character mean for the six characters on the body? eg. GAT036 on attached picture. Thanks in advance for help

There is tRDYI as a timing parameter to enable/disable MRDY.

This parameter is related to MOEX and MCLK. It can be designed in Synchronous SRAM mode, but it cannot be designed in Asynchronous SRAM mode because MCLK is not output external. How should I design it?

Thanks,

Hello,

I've an issue similar to this post https://community.infineon.com/t5/Wi-Fi-Combo/STM32F769NI-Murata-SN8000-Problem-with-high-throughput-clock/td-p/112986.

I succeed to communicate through SDIO with the module, flash the module without any error but I've the error 

/* If your system times out here, it means that the WLAN firmware is not booting.
         * Check that your WLAN chip matches the 'wifi_image.c' being built - in GNU toolchain, $(CHIP)
         * makefile variable must be correct.
         */
         WPRINT_WWD_ERROR(("Timeout while waiting for high throughput clock\n"));
         /*@-unreachable@*/ /* Reachable after hitting assert */
         return WWD_TIMEOUT;
         /*@+unreachable@*/

The value of the register SDIO_CHIP_CLOCK_CSR is 0x64. One time out of 20 it's working and I've the result 0xC0. (Bit 0x80 is set).

With STM32 Connectivity pack, it's working every times.  I can't use STM32 Connectivity pack because I need Wi-Fi Direct (P2P)

I used the STM32 to output the clock for LPO. This clock is always on at frequency 32.768kHz.

The SDIO clock frequency is both 5MHz with WICED and with STM32 Connectivity pack.

I downloaded WICED parameters files from Laird and adapt it to my board. (wifi_nvram_image.h, platform.c/h, platform_config.h). I tested the same set of parameters (wifi_nvram_image.h, binaries files) with STM32 Connectivity pack and it's working.

I check every signals with oscilloscope and I didn't see any major differences.

I use WICED 6.2 because STM32H753 MCU is already added. I adapted files for STM32H733.

Do you have any solutions?

Thank you

• Hardware

  • host: PC, ubuntu 20.04

  • slave: sg130gs(1280*720, YUYV, 30fps) + fpga(spartan 6) + cyusb3014, isochronous mode

• Problem

  • Can't open the third camera with error(No space left). while currently the bandwidth of one camera is about 8 * 2 * 1024 * (1000000 / 125) / (1024**2) = 125Mbps(bInterval=1, bMaxBurst=7, Mult=1), for two is 250Mbps, much less than 90%(from USB3.0 spec) of the 5000Mbps, why can't it allocate bandwidth for the third camera?

Thanks

Hello all,

I am using DAVE CAPTURE_GetPeriodInNanoSec to measure the period of a signal. I am calling that function every 2 ms (500 Hz). When the signal frequency drops below about 250 Hz the status code from CAPTURE_GetPeriodInNanoSec is always CAPTURE_STATUS_NEW_VAL_NOT_CAPTURED. I believe this is because the CAPTURE_GetPeriodInNanoSec is looking for both a rising and falling edge between calls and at input signal frequencies below half of the capture calling frequency that will never happen.

I have modified CAPTURE_GetPeriodInNanoSec such that it only returns CAPTURE_STATUS_NEW_VAL_NOT_CAPTURED if neither a rising nor falling edge was captured. This seems to do what I want. Does anyone have any insight into this?

Another possible solution is to call CAPTURE_GetPeriodInNanoSec at a lower frequency, but that makes it harder to use the filter that I would like to when my signal goes into a higher frequency range.

PS: the reason I need to use the return code at all is to detect when the frequency of my signal suddenly drops to zero. In those cases I expect to get CAPTURE_STATUS_NEW_VAL_NOT_CAPTURED returned and I can use that to know that the frequency is now zero. Show Less

Hello,

 

I am trying to understand my possibilities regarding purchasing a company id for my BLE devices.

When I look at resources on this site, all of them say I can purchase the company id either from Bluetooth SIG or from IEEE.
However, the company identifier provided by Bluetooth SIG is only 2 bytes, so I don't understand how can I use one purchased from Bluetooth SIG as my company id in the device.

I saw that the value set by default (00A050) is Cypress' IEEE address, not the Bluetooth SIG address. I could not find any reference to the company identifier (provided by Bluetooth SIG) of Cypress (0x0131) in the code.

 

Is it possible to use the company identifier provided by Bluetooth SIG? If so, how can I obtain the value for the third byte of the address?

 

Any help will be greatly appreciated.

With Kind Regards,
Omri

@Hello Support team,

We have designed a custom board with NXP I.MXRT1020 MCU and Murata 1MW using freeRTOS. We have an application running on RT1020 which scans the Wi-Fi network and joins the network whose RSSI is better. The software will then continuously performing the ping on google server to verify internet connectivity and communicate with cloud.

Wi-Fi : 1MW
Wi-Fi firmware Version: wl0: Jan 8 2021 06:48:16 version 7.45.230 (984c094 CY) FWID 01-4ab01959
Antenna: Internal antenna as per 1MW certified chip antenna
