PSoC™ 4 Forum Discussions

Hi, I am working on PSOC 4 (CY8CKIT-041s-MAX PSoC 4100 MAX) I am trying to debug the Non-Blocking Flash Write using Poilling Example project . In this example project it is only writing the memory of 256U and I want to write memory more than 256U , I am unable to do that can you help me in that Show Less

I only use the MOSI of the SPI to send data, and there is no need for oversampling, how can I increase the rate of the SPI?

I See the max baud of SPI is 4MHz, and I need it to be 8MHz, the oversample is at least 6, how to config it to 3??

the chip is CY8C4025, thanks.

Hi Infineon.

 

Could you please let us know how to use external clock instead of internal clock on PSoC 4000S?

 

Can user use external clock by following 2 steps?

Are there any other steps required to use external clock, such as adding code other than below 2 steps?

 

If user implement below 2 steps, will the clock source be switched from IMO to external clock?

If user implement below 2 steps, will IMO stop and switch to PSoC operation using external clock?

 

 

=========================================================

Step 1:

Check EXTCLK to enable external clock.

Change HFCLK source from IMO to EXTCLK in the pull-down menu.

 

 

Step2:

Connect an external clock to P0_6.

 

 

=========================================================

 

 

Best Regards.

如题，用的软件是Psoc creator4.4,开始时可以识别烧录，接着插在板子上调试，最近插上软件就识别不到，烧录也不行（试了备用的烧录器是OK的），拆开烧录器，无明显损坏痕迹，也不存在芯片发热烧毁（以前有发热烧毁，更换芯片后就OK了），请问社区的大佬们，有谁知道大概啥方向的问题？主要拆开看没啥明显问题，又没电路参考，很难分析有啥问题？

I use DMA to capture the data from ADC, but the data captured with DMA in release mode and debug mode are different. 

The config of DMA is as follow:

trying to execute  CE195325 – I2C LCD with PSoC 4 example code using C8ckit-043. It does nothing when I execute it.

1. how does the LCD component know how where the I2C component is so it can communicate?

2. Is the code compatible with cy8ckit-043?

3. The only thing I haven't implemented is the reset pin. Is that necessary?

4. Will this work with a 2004 display? (20 character, 4 lines)
