Hello all,

I am currently trying to understand how the UVC host application works. Code is from the zip file linked to by this thread: UVC Extension unit

The host application allows you to either get or set the current firmware version on the FX3. It seems the parameters for the function "SetGetExtensionUnit" (host application) dictate which control is to be executed on the FX3 side. The "dwExtensionNode" parameter  is commented as the "XU Node ID" on line 187. Is this supposed to be the "bUnitID" from the Extension unit descriptor? In the host application code, "dwExtensionNode" is set to 2, while the extension unit descriptor "bUnitID" is valued at 3. The processor unit in the UVC header has a "bUnitID" set to 2, so are we actually calling the processor unit with the host application code?

The next parameter in "SetGetExtensionUnit" is "xuPropertyId"; commented as "XU control ID" on line 188. I assume this is the control ID with possible values ranging from 1 to 31. Assume I wanted to make an exact copy of the Firmware control but instead make it control number 2. I would have to edit the extension unit descriptor such that "bNumControls" was set to 0x02, and "bmControls" was set to 0x03, 0x00, 0x00. In the "UVCHandleExtensionUnitRqts" function on the FX3, I would have to add a case to the switch statement for "wValue", which would recognize control 0x0200 as my copy of the firmware code. I should then be able to edit the host application, so that "xuPropertyId" was set to 2, and I could then get and set the firmware just as if the parameter was set to 1. Unfortunately this does not work, so my understanding is flawed.

This is one of the last major milestones in my project, and would greatly appreciate any help you can offer, thanks.

Can someone please post example how can I measure battery with 022001-0 module. I have the same code working for 012011-0.

When I change the Vref to pin 1.7 and use one of pins 3.X as ADC inputs, the battery measurement does not work.

I am using CYBT-343026-EVAL with WICED 6.2 now.

1.I want to know software strcture diagram of WICED 6.2.

When I read hci_control.c,I saw  Software User Manual (WICED-SWUM10x-R) like below,

but I can't find it.

2.I want to know where can I find Software User Manual (WICED-SWUM10x-R).

Would you please tell me that?mifo​shjl​goto-t_2353976​user_437857088​user_140663973​

Hi

I got a UART transmission block working, sending 4 bytes at a time but the logic i'm using is actuallly not making a lot of sense to me, even though it works.

I was checking if the transmission status was FIFO not full, but what really makes sense is to check if the FIFO is empty so I can immediatly load it with the 4 bytes to send. When I do this, however, it never goes into the if, it's always false even if right before checking it I place the clearTXBuffer and I don't understand why.

Does anyone have any idea? Am I understanding the functioning wrong? I've read the datasheet some 3 or 4 times and this is what I could understand from it.

Thanks.

Dear Developers,

I am using ds18b20 for reading temperature  using the library shared on psoc community. I am able to successfully interface the ds18b20 (dallas) ic . But comparing the result

i found that my ds18b20 is giving 7-8 degress increased drift in the reading. I thought it was sensor fault so i retested the sensor on the arduino where is gives proper reading. I have RTD Pt100 sensor using which i compared ds18b20 is giving proper result on arduino but not on psoc5lp ( kit 59).

This below library is shared in psoc community.

I have a combination bootloader application but I'm having trouble debugging the image in the upper section. There seems to be some issue with my firmware copying/flash writing code but it only happens when the upper image is running and writing to the lower image location (the first firmware copy to the upper location works fine). I don't know how to debug the upper image. I can trick the bootloader into booting the upper image but the debug symbols don't seem to align to the correct code if I do this.

Hello forum members,

i am looking for a way to encrypt an char array before those data are exposed via Bluetooth.

Those encrypted data later will be processed in a secure harbor. So transporting of those are

fully transparent and no security issue so far. What is the best economic way to achieve the

encryption? Maybe an public key based encryption is sufficient?

Thank you for taking time to read this and helping me out to find a solution.
