Hi,

I have a cy8ckit-059 and I would like to power it using a 3.7V battery previously used in a drone. I would like to have a button that turns the system on and off from the battery and also I would like the battery to be charged when the board is connected through the USB port. As I'm really a newbie to this world can you please guide to how can I make it work if it is at all possible?

The battery has all the required protections built in so if I connect it to a 5V 1A source (regular USB charger or PC) it can be charged without any trouble.

Thanks ahead for your help!

Hi,  There,

We are using CYUSB3KIT-003 (the P/N of the chip is CYUSB3014) to design a camera. We need to send a leader and a trailer as single transfers before and after each frame. So I used the override mode to add the leader and trailer. I modified the AN75779 to test the override mode.

I add the leader in the GPIF CB function and the trailer in DMA CB function. I also added 2 states in the GPIF state machine: SOF0 and SOF1 to get the SOF signal from the camera (it’s a pulse 5ms before FRAME VALID signal ) to interrupt the CPU. In these 2 interrupts, I add the 52 bytes Leader of the frame. The resolution of my design is 1920*1200 Mono8 (1 byte per pixel) and the frame rate is 30 FPS. I set the buffer burst size to be 18K (18*1024). So there should be 125 transfer of 18K blocks, one leader and one trailer for each frame. I used AMCap to start the transfer though I know there will be no video in the viewer. I only need to see the USB traces.

But the trace I got is not as my expectation. The data blocks will sometimes be 124, and sometimes there will be one data block between the leader and trailer. The app will stop running after several seconds with an EP_UNDERRUN error. You can see the details in the attachment.

Please kindly give me some help.

Thank you much in advance.

Hi all

I've a bus trap while initializing the GTM clock. in particoular here

I've set a break point on line 121 (address FB86) reg_temp = (uint32)GTM_CTRL.B.RF_PROT; 

once I do a "step" with the debugger on FB88 I get a bus error.

Is this register somehow protected? Where I can get more detail about the cause of the bus error?

Thanks in advance

Hi Cypress,

I recently looking into the 4700S series, but i found that there are not much code example for this series, only 8 of them. 

I tried to follow those examples from PSoC4 such as 4200 series etc. but they are significantly different now.

Is there any resources you can share?

The way Cypress update or extend your component library is quite hard to do the sustaining process. All the functions and components are part specific, which is not quite user friendly, just my opinion.

Anyway, please see if you can share any helpful tips. Thanks!

Hello,

my stm32mp1 processor is connected with the USI module WM-BN-BM-26A that contains Cypress CYW43438 chipset via SDIO. I'm using driver brcmfmac and i'm able to connect to the wifi and access the net.

I'd like to send software commands to the wifi module via the wl tool.

I'm not able to find the right binary for my architecture (armhf), can you provide it?

It would be best if libraries were statically linked.

Thanks

I have a use case where 2 central devices need to connect to one peripheral. I am using psoc6 as a peripheral and phone as central devices.

The problem I see is that when one central device is connected to psoc6, the other central device does not discover the peripheral. I have increased the Max number of ble connection to 2 in BT configurator, but not able to connect two devices.

I am using 'BLE_Battery_Level_FreeRTOS' example and just increased the Max number of ble connection to 2. If I connect one phone via 'CYSmart' app, cysmart app on another phone does not show the peripheral in the list.

Is there anything additional thing needed to establish connection other than increasing the Max number of BLE connections in BT configurator?
