您好！

目前程序编译后，发现flash空间不够用了，我这仪器代码量128k应该是够了的，ST的64K也够用，现在程序还没写完，显示已用97.9%，现在程序存储数据就不对了，请问是不是哪些东西比较占用空间？

谢谢

Hi!

Is it possible with some internal magic to get a more flexible pin-placement for I2C SCL/SDA signals on the psoc4L series?

Thanks

Hi everyone! I am a student working on a senior project using CYBLE-212006-01 to communicate through SPI with the ATWINC1510-MR210x. Does anyone have a working function of SocketInit() or tips for getting started? Any help or resource would be greatly appreciated. We have been using this software guide http://ww1.microchip.com/downloads/en/devicedoc/atmel-42418-software-programming-guide-for-atwinc1500-wifi-using-samd21-…  but it does not use the CYBLE component.

Hi all,

I am trying to implement a bootloader which connecting with a external memory by SPI, for that I use (as reference) the document " Psoc 4 BLE - OTA Firmware Upgrade using Serial NOR flash".  As it is shown in the screenshot at the moment I start the SPI the message is "ERROR: Ram overflowed with stack"

Any idea about it?

the result is

when in dis-comment this line :  ( I put this line (EMI_SPIM_Start()) to easy shown the behaviour)

The TopDesign is :

Thanks very much in advance for your help, I hope some of you have any idea about it.

Regards.

Hello,

i would kindly ask if it's possible to switch the IDAC's polarity? The configuration in the IDE is fixed? We would control the configuration by software API as needed.

So is this possible?

Thank you and kind regards,

Hello,

I am using a CY8CKIT-042 PSoC 4 Pioneer Kit.

I need to be able to produce microsecond (or less) long pulses at fixed intervals. I know of the CyDelayUs() function, but it's not as accurate as I need it to be, the way I'm using it at least.

Firing a digital output, calling CyDelayUs(1), then turning the output off produces a pulse of about 3.2 us as measured on an oscilloscope, and that's as low as I could seem to get it.

I also tried using a Timer Counter component in One shot mode with a period of 10 and a clock frequency of 6 MHz. With this configuration it should count up to 10 in 1.67 us, then turn off. In code I have a digital output firing if the counter is greater than 0, and turned off otherwise. Looking at the output with an oscilloscope, I am seeing a pulse duration of exactly 2.5 us, and no matter what I do I can't get it any faster than 2.5 us. Even with a clock frequency of 12 MHz and a period of 5, which should give me a pulse of about .42 us, I still see a pulse of 2.5 us. It seems the speed is being bottlenecked by something else I am not aware of.

I know the processor is capable of doing this, as I can see <1 us pulses using a PWM component with the right configuration, but I need single pulses at fixed intervals, sometimes several seconds apart.

So, what is the quickest pulse I can manually achieve, and what is the proper method of doing so?

Thanks

Hello, I am using CY8C4025AZI-S413. i want to implement brown out reset. As per one example i have selected global signal reference as component , i am not able to find power system interrupt.Can anyone help me regarding this, i would appreciate the help.
