PSoC™ Creator & Designer Forum Discussions

  Hi everyone,

I am using CY8CKIT-062-BLE kit, PSoC Creator 4.2 (4.2.0.641)

My idea is using CM4 core to capture GPIO interrupt (SW2 button), set a flag variable then using CM0 to do something (such LED toggling...) when this flag variable is set.

GPIO Int is handled by CM4 core, so that I MUST place "User_GPIO.c" file in CM4 folder (otherwise i got error with variable &SysInt_Switch_cfg).

In this "User_GPIO.c" I created 2 functions: User_SetVal_Pin_SW2_Int_Flag(), and User_GetVal_Pin_SW2_Int_Flag() to clear and get value of that interrupt flag, respectively. Their prototypes are also declared in "User_GPIO.h" under folder "Shared Files" .

Core CM0 processes general system events by calling function Get_Event() which calls to User_GetVal_Pin_SW2_Int_Flag() to check the Int_flag continuously.

Function Get_Event() located in "User_Event_Interface.c", and this c file already got this line #include "User_GPIO.h" .

However, i got build error with msg PSoC6_IoT.cydsn/User_Event_Interface.c:49: undefined reference to `User_GetVal_Pin_SW2_Int_Flag'

Can anyone please help me to fix this?

I created a port that uses 16 pins on the processor. These are simply feeding LEDs that I want to update at the same time every time. This spans across multiple ports: P0[0..6], P1[0..3], P1[7], and P2[0..3]. I see that I'm able to map them as spanning but how to I reference the whole port in code?

I am new to this kit. I tried to connect a character LCD and I couldn't make it work only if I connect it to port 2. I read on some places that other ports such as 3 have analog pins and therefore it could introduce some noise. I connect it to port 12 which should be suitable for digital connection. However, it didn't work neither.

It is a little bit disturbing because the LED is connected to 2.1 pin.

Is this behavior is normal ??

Please answer below.
The same question is written in English and Japanese.

・English

I think the horizontal axis of CapSense _ Tuner is the number of samples.
I would like to sample as soon as possible. Which parameter should I change?

・Japanese
CapSense_Tunerの横軸はサンプリング回数かと思います。
なるべく早くサンプリングしたいのですが、どのパラメータを変更すればいいですか？

Hi

Can someone please advise how I fix this issue when I open a project in new install of Psoc Creator on Windows 10 machine
