PSoC™ 4 Forum Discussions

Hi,

I am using CYBLE-212020-01 module which sends with notify some values over BLE from App and made a demo using the CySmart Android App found here:

https://www.cypress.com/documentation/software-and-drivers/cysmart-mobile-app

I want to pass easily from GATT DB screen from the carousel view to directly the sceen Gatt Charateristic Notify Details.

How I can to do this easily?

Thanks in advance for any replies.

Hello,

I have questions about how the sample project works. The customer used the code from the sample project to evaluate the electrostatic sensor board.

   "CE210709_CapSense_Linear_Slider_and_Buttons"

   "CE224899_PSoC4_Low_Power_CapSense_Hybrid_Sensing01"

In the process of 'PROCESS_DATA' of Switch condition statement of main.c, the customer code saves the value of buttonStatus in a static variable and controls the GPIO to notify the status to the main CPU.

[problem]:

Continuously touching the CSD sensor causes PSoC to stop responding.

(Customer refer "CE210709_CapSense_Linear_Slider_and_Buttons")

[Results of customer analysis]:

1) GPIO which notifies the sensor touch event to the main CPU is not working.

2) However, when a problem occurs, "PROCESS_DATA" is executed normally in the debugger, and the sensor touch status can be acquired accurately. (Q1)

3) Furthermore, the GPIO control function (IRQpin_Write (0)) that notifies the main CPU is also executed normally. This can also be confirmed from the fact that the intended value can be obtained with the IRQpin_Read () function. (Q1)

4) According to the oscilloscope waveform, GPIO is not working.

5) Once in this state, the GPIO remains inactive even if the sensor touch operation is performed.

6) When I2C communication from the main CPU occurs, PSoC returns to normal operation and GPIO is controlled according to the sensor touch operation.

7) If CySysPmSleep () is deleted, this problem does not occur.

Question1:

According to the customer's report, the debugger normally exits sleep (CySysPmSleep ()) and shifts to "PROCESS_DATA" processing, but isn't the sleep function invalid during the debug processing of PSoC Creator?

[Guess]:

- Isn't the CySysPmSleep () running in the "WAIT_FOR_SCAN_COMPLETE" state not returning from the sleep mode after the completion of the key scan?

- 6) Isn't the problem solved by I2C communication from the main CPU because PSoC returned from sleep mode by the interrupt by I2C communication?

[Additional analysis result]:

From the source code of "CE224899_PSoC4_Low_Power_CapSense_Hybrid_Sensing01"

Before CySysPmSleep ();

  Added interruptState = CyEnterCriticalSection ();

After CySysPmSleep ();

  Added CyExitCriticalSection (interruptState);

The above solved the problem. (See attached sheet)

Question2:

CyEnterCriticalSection () has already been done inside the CySysPmSleep () function, so the addition of this code only makes a double critical section transition.

Why does adding CyEnterCriticalSection () solve this problem?

Hello,

I'm using the MiniProg3 (!https://www.cypress.com/documentation/development-kitsboards/cy8ckit-002-psoc-miniprog3-program-and-debug-kit  ) programmer to program my Cyble 012011-00 (!https://www.cypress.com/file/212456/download) module with EZ-Serial hex file (!https://www.cypress.com/documentation/software-and-drivers/ez-serial-ez-ble-module-firmware-platform).

I'm using PSoC Programmer software to program the hex file to the board, which does work as seen in the pictures. However, when I then try to connect it with my RX & TX pins to view the output in a terminal, it doesn't output anything. The documentation of EZ-serial says that it should output a system_boot event upon reset/power on. When I reset the module, the event output is not displayed. Sending commands, such a "/PING" is also does not provide a response.

I'm pretty clueless about what I am doing wrong at this point. Any help would be greatly appreciated!

Kind regards,

Toink

Hi.

My customer use PSoC 4100S Plus.

My customer changed Sense clock frequency on the CapSense Tuner.

3000kHz   =>  1500kHz

I recognize that if you lower the Sense clock frequency, the raw count will decrease.

However, this change has increased raw count.

What could be the cause?

Best Regards.

Hello everybody,

Is it possible to implement this architecture of circuit In PSoC 4200L with the Opamp used as integrator and two internal analog switches S1 and S2?

What are the switch components in the internal Cypress library?

the architecture for duration measurement is as follows:

Thanks in advances

Soukayna,

The Segment LCD can work properly when using High Speed Mode with hs_clk set to 1M ~ 3M Hz. But when set to use Low Speed Mode, the LCD can't work properly, with all the icons displayed on LCD. I can't turn off any icon by writing LCD_Seg_PIXEL_STATE_OFF to the corresponding pixel, while this method works OK in high speed mode. Currently using the PWM Driving Mode, but Digital Correlation has the same issue.  Could somebody kindly tell me how to drive Segment LCD in Low speed Mode?

I also notice that with High Speed mode, when the hs_clk is set to a low enough value (such as 100K), the same issue happens, i.e., all the icons are displayed and can't be turned off.

Hi all, I've got a pretty noobish understanding of the PCB world, but the various guides on it all have given me a pretty good understanding on capsense, enough to get started.

I'm currently trying to design a touchpad. It needs to be 30mm x 150mm and I've decided a 4x20 grid will do the trick (each block's diagnol length is roughly 7.5mm).

I'm currently very stuck on picking out a MCU. There seems to be a ton of options and I'm not sure exactly what I might need.

1. What is the best MCU to that has 48 capsense i/o pins for a 4x20 touchpad? (I am correct in assuming I need 48 capsense pins for a 4x20 trackpad I hope...)

2. What is the difference between capsense i/o and GPIO? On some MCU datasheets, they are listed as different things, but other documents seem to state you can use GPIO for capsense?

3. I'm very new to Eagle as well but I can figure that out thanks to Youtube tutorials... A few PSoC devices are there in my Eagle library by default, but I'm not sure if any of them will work in my case. Once I know which PSoC device I need, how do I find an Eagle library containing it?

4. Are there, by any chance, how-to videos or tutorials demonstrating the schematic/PCB design of a touchpad? Any examples I could take a look at, just to aid in the learning process?

I am looking for the PSoC 4 BLE power calculator mentioned in AN92584 section 3.4 ( excel worksheet) where can I find it?

Hello,   

       使用J-link对芯片进行烧录时发现, 当Debug select 选择SWD模式时,  芯片的烧录,  擦除完全正常.  但是当Debug select 选择GPIO模式时 ,HEX文件第一次烧录时是可以正常烧录 ,然而第二次烧录的时候 ,J-link就会提示连接错误 , 导致无法下载. 这时把GPIO模式下的程序使用Psoc programmer擦除 , 然后J-link又可以正常连接烧录 , 手动复位芯片也无法正常连接J-link.

       我有看论坛上有类似的问题,可是办法并不适用,当前使用J-flash版本为V6.34,论坛解决办法链接如下：

          [SOLVED] SWD connect fails on PSoC in low-power mode - J-Link/Flasher related - SEGGER - Forum     

       所以想请教各位是否有能够使用J-link下载low_power的程序的方法,谢谢！！   测试过PSOC 4000S和PS0C 4100S PLUS系列,现象一致.

Best Regard!
