I see that my device wakes up from sleep before the WDT interrupt.

how can i determine the source of the interrupt that caused the wakeup?

I used CyBle_Stop(); before entering sleep. So i guess it is not BLE, or can psoc fail enetering sleep even if BLE has stopped?

thanks.

AN54908 calculation shows 65nm having a lower LSBU factor. In past experience smaller die have greater error. Are there improvements that accounts for the lower LSBU in the 65nm versus 90nm?

Hello everyone,

I have a project where it is nessesary to know the start-up time. Meant is the time between connection to a power supply and reaching the main loop in active mode.

Does any body know how long this takes?

Try to avoid the super cap.

Thanks and best regards

Hi I am a newbie and wanted to understand if it is possible to advertise the data on some value change to the bonded device.

I am creating the android app which connects to my ble device and pairs it. Now on some button press on the device, I want it to be notified to the mobile app. As far as I understand, once the device is paired and bonded, its not possible to advertise the data from the ble device.

How should i handle this scenario?

Appreciate the help. e.pratt_1639216​

Hi,

I am trying to use CARKIT interface of FX3s. There are some example

codes  in "001-76074_EZ-USB_FX3_Technical_Reference_Manual.pdf"

as given below.

/* Enable the USB PHY connections. */

GCTLAON->control &= ~CY_U3P_GCTL_ANALOG_SWITCH;

/* Enable and set the EPM clock to bus clock (100MHz). */

GCTL->uib_core_clk = (CY_U3P_GCTL_UIBCLK_CLK_EN | CY_U3P_GCTL_UIB_CORE_CLK_DEFAULT);

GCTLAON->control |= CY_U3P_GCTL_USB_POWER_EN;

CyU3PBusyWait (100);

CyU3PUsbPowerOn ();

UIB->otg_ctrl = CY_U3P_UIB_OTG_CTRL_DEFAULT;

GCTL->iomatrix |= CY_U3P_CARKIT;

UIB->chgdet_ctrl = CY_U3P_UIB_CARKIT;

But where those definitions such as "CY_U3P_GCTL_ANALOG_SWITCH" are given?

I searched in Linux files but could not find anything.

Can you please share the whole project? I will also appreciate an example code to set

FX3S in CARKIT mode using CTL11 and CTL12 pins.

Thank you.

I have constant array: const uint8_t test[10] = {1,2,3,4,5,6,7,8,9,10}.

If I changed only one number inside the array, for example: const uint8_t test[10] = {1,2,3,4,5,6,7,8,9,11}, hex file changes on two positions:

Project type is Bootloader Project. I find out that this is the reason why hex file has changed on two different places.  Looks like that the "second place" is  bootloader "checksum".

I couldn't find any info about "bootloader checksum", is it possible to get any details about it (checksum calculation, location in hex file...)?

I am developing a project with CY8CKIT-059. This project required to run up to 1 year.

I try to put the microcontroller into Sleep mode to reduce current consumption but until now, there is no luck.

When I put the CY8CKIT-059 into Sleep mode, the current I measured is always around 1mA.

However, the datasheet stated that the IC can consume only several uA during Sleep mode.

I try to slow down the CPU clock speed as well as turn off all other components, but the whole kit still takes 1mA of current.

Any idea how to get that mysterious value of several uA?
