I tried coneccting CySmart 1.3.0.8 and CY8CKIT-042-BLE-A using default settings.
Then, too many peer devices were listed in master tab.
Could I delete peer devices from list when I push [start scan]?
and is there a way to display only Cypress(Infineon) devices on master tab?
Or Could I serch and sort devices with device name?
best regards

Show Lesshi, Im music developer try to create new instrument basic on Eastern instrument ,i start my prototype with Arduino board .
I want to change for Infineon microprocessor ,I need same touchkeys function in this link .
- different dimensions keys board
- Bluetooth MIDI/OSC transmit messages controller
- 156 touch switch
- 26 touch keys with full midi/osc controller function
-OLED display
((My main question is which microprocessor i need to start with .))

Hello together,
in the description of the HSIOM_AMUX_SPLIT_CTL-Registers I found that there seems to be a switch to connect the Bus to GND/VSSA. The switch is named SWITCH_AA_S0 (or BB for Bus B). In one of my application it would be helpful to use this switch to discharge the whole bus.
Is there any documentation how this switch works? I tried to activate it, but I didn't see any success.
Unfortunately I did not find any details in the TRM for PSoC4100PS. Also I can't find any details in the code or in the analog routing graphics.

Show LessHi,
When we compared samples of the CY8C4124AXI-443T produced at different dates and factories, the differences detailed below were detected
In order to understand which of these differences in top marking and lead frames are correct, we need your official statements that we can use.
Reverse Logo colors, different alignment and size
TWNxxxx vs xxxx (There is no any Country Code. PHI or TWN)
Different Lead Frames (X-ray image)
Are there any official statements about these differences?
Show LessHi 正如我标题所描述的,我们现在有客户要测试cy8c4025相关的capsense防水功能,但bsp中没有相关芯片选择。是否是需要新建一个empty app然后从其他 项目移植过来。
Hello
My application calls the below function during a connection. It is configured as a peripheral. The connection interval is 100ms min/max with no 0 for slave latency. I'm reading a voltage from a sensor, sending it into an onboard opamp and then reading the output via the ADC. The problem is an inaccurate adc result. The reading I get is slightly higher by a few counts and sometimes toggles. If I don't call the function, the reading is accurate with no toggling.
I feel that placing the device into deepsleep between events is the issue but I don't know how to solve it. I've read the low power application note but I'm confused about what deepsleep does behind the scene. Do the GPIOs retain their states? Are the analog peripherals altered in any way? Is VREF affected?
thanks for your assistance.

I'm using PSoC Creator 4.4 with a 4200 M0 processor. When debugging and stepping through the assembly code, the system freezes on attempting to execute a branch with link to a label instruction: "bl label" The label is valid and runs correctly in other situations. Creator freezes and there is no other information at that point.
When I halt the processor, I get the error message:
"The run request failed. Encountered error (This INTERRUPT operation is not valid while the state is Paused.)"
"The request to run the application on the target failed. Make sure that your code is valid and that the selected target supports debugging."
I would greatly appreciate any suggestions on how to find the cause of this. Thanks very much.

Show LessHi,
I am doing a research project using CY8CKIT-042 PSoC4 Pioneer Kit (CY8C4245AXI-483). The prototype device is powered from a battery of 40mAh capacity. After the normal mode operation when I power OFF the device, the uC enters into deep sleep power saving mode. From the deep sleep mode when I connect charger for charging the battery or press the power ON key then uC exits from deep sleep mode and enters into normal mode.
However in an extreme case, the battery was weak while the time I powered OFF the device then in between the deep sleep operation state the battery was fully drained and there was no power source to the device and uC wad fully turned OFF.
After the above scenario, when I connect a power source to the device the expected behaviour is that the device should turn ON automatically due to the reset signal that appears on connecting the power source. However, in some scenario the device didn't turned ON and a re-flashing of the uC was required for turning ON and resuming the expected behaviour.
Can anyone suggest some root cause for this behaviour and what could the possible solution to avoid it?
Thanks in advance.
Show LessHellow World example code, is an output string using cy_scb_uart_putString ().
How do I change to printf?
Although retartget-io was found, it can only be used for PSOC6, POSC4 cannot be used.
