Hi All,

I am trying to interface PSOC 5LP Prototyping Kit, with a 16x2 LCD (RG1602A) over Port P12 [6:0] and have made the corrections properly ( triple checked).

And made the DWR and pin assignment as well as Step 8 (main.c) as mentioned in: http://www.airsupplylab.com/psoc5-lp/17-psoc5-lesson-07-interfacing-character-lcd-display-module-with-psoc.html#for-cypress-cy8ckit-059-prototyping-kit

I have connected the LCD pins according to above article on P12[6:0] and programmed the PSOC.

But there are no characters displayed on the LCD, instead the first row is all black boxes as shown in the image below:

And i have searched and found out the following info from one of microchip forum: "One row of boxes at the top of a two line display almost always indicates either bad initialisation or a data or control wiring fault and is because the diisplay controller is still in its power up default of single line mode which needs a different contrast voltage to two line mode.

As the display section of the schematic looks sane, the problem is probably either the actual sequence used or its timing - either inter-command delays or setup and hold timing for strobing out each nibble."

Can you please help on what to do in this scenario and  what could be the issue and how to resolve it?

Regards,

Yash

We are currently working in a home automation start-up and is using Wi-Fi for communication. It would be highly beneficial if you could provide the details of 2.4 GHz transceivers and WiFi SoCs, having a minimum of 30 GPIOs.

Also, about the microcontroller that support the features of MATTER.

Hi,

We use AP6212 (BCM43438 based) module on our board and we need wl utility to do compliance testing. Local FAE could provide the wl binary with bcmdhd driver, but we use brcmfmac driver, can anyone help me to provide this? Thanks

Our hardware platform / Env:

- Linux Kernel 4.19, armhf

- Wi-Fi driver: brcmfmac

- Raspberry Pi CM3+ based

Best Regards,

Paul

Hi,

I have successfully have data transfering over a SPP using the HCI UART in Raw mode, by following https://community.cypress.com/t5/Knowledge-Base-Articles/How-to-Use-HCI-Raw-Data-Mode-in-CYW20706-KBA225970/ta-p/248902

However, if I start sending a file and compare it to the original (using CYBT-353027-02-EVAL and using a PC via RealTerm 2.0.0.70 on both ends without hardware flow control selected) the file transfers successfully except for a section somewhere near the beginning. I think this is due to a receive buffer filling up before the BT module has woken from sleep. Sending a few bytes before sending the file (to wake the BT module up) results in a perfect file transfer.

I tried selecting use CTS/RTS hardware flow control on both serial links (BT & HCI serial) but this does not fix the problem, as I would expect to.

Is there something else I need to do to enable hardware flow control? From other posts it sounds like flow control on HCI port isn't optional, but if so why the missing part?

I have attached my main source code.

Thanks,

Ian

Hi 

I had selected "CN" by wl country CN, and wl chan_info displayed Channel 12 and Channel 13.

But I still cannot assoicate with the AP which is on channel 13.

The firmware is the standard firmware, not MFG test firmware,

BlueZ 5.46 in Linux

It is a Murata LBEE5HY1MW,  Cypress (CYW43455).

We are sending a device though certification for BLE and was requested by the test lab to provide the following. 

1. For Receiver blocking, need conducted sample which with the Direct Test Mode(DTM) enabled

I need assistance on how to configure the device to meet the requirement. 

In electro-tech-online I asked about my need of making a device wich could generate a sinusoidal signal (by PWM method) with a 18F4550 Ucontroller, but it seem it is not possible. Someone named Dana suggested me to see the information about this cypress device.  So, the questions are:

1. Is it possible to make a threephasic 5 KHz signal (3 120 degrees unphased signals), wich could be used by a power stage to handle about 1 ampere each branch in some kind of power transistors?

2. If the signal is analog, is it a way to isolate the control stage from the power stage?

3. Is it possible to stop or restart this signals with a Ucontroller signal?    Or further, to control amplitude?

4. Do this device is sold and there are existences now on Mouser, Arrow or DigiKey?

Thank you for your time
