I am trying to set value on my Characteristics which is read able. But it always gives me 0 ( zero ) Value.

The application is very simple, I am trying to set led state from writing  values, which is working good. But I want to set that same led state in another characteristics. I have gone through custom profile implementation document, but that didn't work for me. Can any one please guide me?

Below is my main code for your reference.

Hello,

I'm trying to use the function powf in a design.

The target device is CY8C4245AXI-483.

Of course I've included math.h but when I build i Get the message:

"Build error: undefined reference to `powf'"

Building the same code on another target (CY8C4025AZI-403) biuld is successfull.

Can You please help?

thanks,

Alfonso

Hi community，

我的 Modustoolbox 又又又不能用了，同时我另一台电脑也不能连接，请问怎么解决啊

似乎这十分不稳定，你们有遇到这种情况吗

我们有个Cypress PSOC 应用的问题，想咨询一下。

我们目前用的CY8C3246,  firmware 用到了Watchdog

从库函数的描述看，有4档 timer periods.   我们现在选择的已经是最长的间隔了。

CyWdtStart(3, 0);      //  enable WDT  2.048-3.072s

我们想用更长的timer periods，有什么办法吗？

Below is PSoC 4000S TRM description about POR.

https://www.infineon.com/dgdl/Infineon-PSoC_4000S_Family_PSoC_4_Architecture_Technical_Reference_Manual_(TRM)-AdditionalTechnicalInformation-v04_00-EN.pdf?fileId=8ac78c8c7d0d8da4017d0f915c737eb7

Could you please let us know the conditions under which POR becomes valid again after POR is disabled at VCCD rising edge?

Will POR remain invalid unless VCCD goes completely to 0V after POR is executed at VCCD rising edge?

Best Regards.

I need to output on a small PSoC4 a PWM signal that is varying from 1% to 50% in 1% steps.  Can this be done in hardware on a PSoC4 device.  PSoC used: CY8C4025LQI-S402

I've seen examples using two PWM's and Smart IO but there duty cycle goes from 1% to 50% and then inverts.  I only need 1% to 50% maximum not the inversion portion(breathing in and out LED's examples).  I need to start at 1% go to 50% and stay there.  Does anyone know how this can be done on  small PSoC device as I listed.

My goal is in code,  to adjust the step percentage value based on a voltage measurement.

Thanks

Hello,

I made a 4-bit count component by verilog HDL, how can I set up a API like those standard components? such as the command of  Counter_WriteCounter(), Counter_ReadCounter().
