Dear Receiver,

There is an IoT device and it will be designed to connect to AWS (Amazon Web Service). 

Under this condition, do I need to select a MCU (PSoC_6, CYS0644xx) with Amazon FreeRTOS support ?!

I feel a little confused about...

If I select a MCU (PSoC_6, CYB0644xx) with only FreeRTOS support, dose this mean this IOT device can't connect to AWS ?!

Thank you so much.

I am using CY2305 with the configuration shown in the schematic below.

I measured the waveform of CLK1. It has a lot of jitter. (Approximately 2ns)

According to the data sheet, Cycle-to-cycle jitter is 200ps(max), but there is no Period jitter spec. Is this waveform normal? If yes, what can I do to reduce jitter?

I measured CLK1, but the waveform (jitter) is the same for the other output pins. It does not change depending on the load of the opposite device. Jitter tends to increase at high temperatures.

Thanks,
Tetsuo

Dear Engineers,

I have one customer gonna make a Bluetooth speaker , he is considering using Qualcomm SOC for this project.

I have promoted him CYW20721 for replacement, but he is concerning about performance of Cypress SOC.

He want to know: Have CYW20721 been used for any Bluetooth Speaker or Audio transmission application product.

He also want case study of A2DP of CYW20721 .The most important feature that he need : 1 phone can connect to 2-3 Bluetooth Speaker at the same time.

please support me this case so i can persuade this customer using Cypress SOC

Thank you and best regards

I am working on a project and trying to interface the CY8CPROTO-063-BLE board with an external I2C CapSense buttons and slider. Should I use the built in CapSense module, or just I2C? Attached below is the module I am attempting to interface with.

Hmm,  all posts are questions now.

I am working (very much part time) on a psoc5LP printer control project.  Life is what happens while you are making other plans.

I chose to use the Ramps 1.4x board for printer control due to availability and price. You can purchase built Ramps boards very cheaply.  I chose the CY8CKit-059 ('059') for much the same reasons, but it is now out of stock. 😟

I created an adapter board to adapt the '059' board to the Ramps board. It is now at version 1.3.  (yes, 3 previous mistakes)  I have posted the Eagle files for the adapter board at socmaker.com.  The schematic and board layout images are also shown on the site in case you want to roll your own using the information presented as your template.

I also have several posts for using the '059'  USB ports (micro-usb and the finger connector) with windows, mac, or linux.  And several other items.

Enjoy!

I am using  xmc1300 development board for PFC stage in 3.4kW onboard EV charger. In the software for PI  voltage control loop I have to set the max power limit as 3.4kw. This power limit is also used in duty cycle calculation for MOSFET gate signal. The max dc bus voltage at LLC stage is 64v and the  max current rating is 53A.  How to scale this 3.4kW power limit , so that I can use it in the software calculations. I am using DAVE 4.4.2 VERSION.

It is connecting HS device as Upstream. And it is necessary to confirm the HS Host in the USB signal quality test(e.g. Proper Eye Measurement) . Is it necessary to make any settings on the HX2LP for signal quality?
Is there anything else I should do other than putting the Host in test packet mode?

The HX2VL has a TEST pin. Not in HX2LP.

Thanks,
Tetsuo

Here is a system sample program hello_world. The sram usage rate of the program after the default compilation is too high, I now want to reduce the sram usage volume. I have tried to delete some unused libraries in the library manager, but it seems to have no effect. May I ask this How to solve it

• Hardware

  • host: tinker board 2s(rk3399)，kernel 5.13

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

• Problem

  • Run this script on host

    #!/bin/bash
    ​
    while : 
    do
            yavta -c30 /dev/video0
            sleep 2
            yavta -c30 /dev/video1
            sleep 2
    done

  • After random time(from minutes to hours), one of these cameras would be stuck

  • USB packets captured by tcpdump indicate that the host keeps polling(isochronous) the slave while the slave keeps responding with a data packet with zero-length

  • After this, if I restart the test script, the device that is stuck will be missed

• some trials on other settings also failed

  • ov5640(1280*720, YUYV,30fps) + cyusb3014, bulk mode

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

• In addition, test with a single camera is fine

Any ideas? thanks
