PSoC™ 4 Forum Discussions
Hi.
I want to handle some registers in CY8C4045AZI-S413.
But there is no detailed information of them in TRM /Family Datasheet/Module datasheet,etc.
For example, in a control register, every bit should be introduced.
Is there such a document?
Show LessHello Everyone,
I Built the one project , It have capsense, I2c , UART, timer blocks but i found the one warning like setup timing violation of cyHFclk.
please tell me how to avoid this warning. (should i worried about it?)
Timing details attached with this case.
thanks ,

It is described as "VDDD and VDDA should be shorted externally.
"In the PSoC4100SP, can you not set “VDDA (5.0 V) ≠ VDDD (3.3 V)”?

"VDDD and VDDA should be shorted externally."と記載されています。
PSoC4100SPでは、"VDDA(5.0V) ≠ VDDD(3.3V)"といった設定はできないのでしょうか?

Show LessI am porting my firmware from EFM32 MCU to PSOC 4. I am not familiar with PSOC 4 and it looks like Cypress PDL does not support PSOC 4. I want to know if Cypress provide a C library for PSOC 4 like EFM32 emlib library?
Thanks.

Is this correct?
"SID185 vRISEIPOR" is the reset release voltage.
"SID186 vFALLIPOR" is the voltage to reset.
・Japanese(日本語)
以下、正しいでしょうか?
「SID185 vRISEIPOR」は、リセット解除の電圧。
「SID186 vFALLIPOR」は、リセット状態にする電圧。

Show LessHello,
my simple DCC decoder project gives a
"Warning-1367: Hold time violation found in a path from clock ( Clock_1(FFB) ) to clock ( \Bit_Timer:cy_m0s8_tcpwm_1\/tr_compare_match )."
which I don't understand.
My project:
The top DFF samples 80usec after a rising edge the DCC line
and the DFF below generates the according clock.
Its clk is fed by the negative cc signal, to be shure,
that DCC_Data is stable.
After 100usec, DCC_Clk is brought to LOW.

Even though most of you may be relatively familiar with the various types of mechanical controls, the same does not necessarily apply for capacitive ones. So, let’s start off by defining the most basic elements of capacitive sensing.
Capacitive buttons are the simplest touch - enabled controls out there. Buttons simply alternate between ON/OFF states when touched.
Capacitive sliders consist of groups of buttons, usually more than three. Sliders use buttons to report linear touch position.
Capacitive wheels are also groups of more than three buttons. Wheels use buttons to report angular touch position. Wheels can also be referred to as rotaries.
Capacitive controls can detect touches even if they housed under materials that cover them. Do you want an all-aluminum body for your device? No problem, you can just use capacitive controls and house them underneath it!
In fact, with proper design and capacitive touch sensor controller tuning, capacitive controls can work under a wide variety of cover materials (also called overlays) of various thicknesses.
But it’s not just the freedom regarding overlays that you can gain from using capacitive controls. You can also experiment with curved or bent designs, as capacitive sensing has evolved enough to be able to withstand bending!
In this use case, we will optimize a touch remote light switch. Traditionally, such a device would feature mechanical components. However, we'll show you how easy it is to design a capacitive- based device, if you have the proper tools.
To refine the design, we’ll use a combination of simulation and guidelines.
We proceed to draw the initial design of the model, which you can see above. This rough design has the following specs:
- Buttons with sharp edges and 2mm clearance
- 2 layer pcb with cover glass (50x70mm)
- No traces, as we’ll add them later

Show LessI designed a loop powered transmitter with XTR116, I made this application with Cy8C4025azi-S413. I used PWM block to generate DC for XTR116, but the PSOC does not work properly on supply provided by XTR116, Almost 24mA current PSOC draws which XTR unable to supply. The system clock I reduced to 6MHz. PWM clock is 12mhz.
I expect the PSOC must work on low power at 5mA in active mode
