PSoC™ 4 Forum Discussions

In the PSoC4 SCB manual I find a particular statment

Would this mean that 2 communication modes can be enabled simultaneously on a single SCB?

I mean is it possible to enable I2C and SPI on a single SCB block? If so, how would the pins be configured for the same?

Hi

1. Design with PSoC 4100S. XRES pull-up resistor is 4.7k, capacitor to GND is 0.1uF. No pull-up or series resistor on SWDIO and SWDCLK. System power should be 5V.

2. Miniprog3 can program PSoC at 3.3V, cannot program PSoC at 5V no matter programmer powered or external powered.

    While using PSoC Creator, powered at 5V, we found IC part number could be detected, "Programming" was shown in the output window but couldn't move on and then failed.

3. Miniprog4 cannot program no matter powered at 5V or 3.3V. It failed at detecting IC.

Could you give some suggestions on how to fix the problem ? Thanks.

Hi,

I am using CY8CKIT-042 PSoC® 4 Pioneer Kit. I am using it for the CapSense design with 10 buttons and 2 sliders.

I can see that, this kit has an in-built CapSense slider with 5 sensors.

Due to shortage of pins which are required for my project, I tried using the above in-built capsense pins I,e P1_1, P1_2, P1_3, P1_4 and P1_5 for my external custom CapSense.

But I couldn't get the capsense input sensed through these pins from external capsense.

Please suggest if there is any workaround.

Hi,

I need suggestion and a little clarification regarding the central -peripheral example PSoC-4-BLE/100_Projects_in_100_Days/Day012_Central_Peripheral/Central and Peripheral/Central and Peripheral.cydsn at mas…

I would like to know if there is any  flow chart also how do i put the code in the ble stack handler with respect to events without the commands through COM port.

Implementing the same as in example without the Com port commands.

Thanks,

Uma

I am using CY8C4248LQI-BL483. I have a bootable stack and application. I am bonding to the device. I'm using em_EEPROM V2.2

When I write to a secure BLE characteristic from my phone and then some time later in the main context call Em_EEPROM_1_Erase(), when the firmware next reaches CyBle_ProcessEvents(); it all hangs. I don't receive any error messages from CyBle_ProcessEvents(); nor from Em_EEPROM_1_Erase();

I can increase the amount of time after writing a secure BLE characteristic before calling Em_EEPROM_1_Erase() and the code will still hang when it reaches CyBle_ProcessEvents();

I can write and read and erase from the EEPROM as long as I do not write to a characteristic.

Is there a known bad interaction with Bonding or BLE and the Emulated EEPROM? Is there a workaround for this?

This does not appear related to KBA228069 as the device does not need to be powered down for this interaction to occur.

Hi,

I'm working on a USB device for a specific class and I need to send a zero length packet if my last packet was a full packet (which seems to be a fairly common requirement.)

Therefore I need to know that the max packet size is ... obviously I know because I configured it on the component, however it seems crazy to duplicate this in the code and run the risk of one changing without the other. Is there some way of getting this programmatically?

(I can see it deep in the descriptor defines, but I cant see a simple and foolproof way of getting at it.)

Also, as a side question ... am I right in assuming that for bulk endpoints LoadInEP() only supports transfers up to the wMaxPacketSize?

Many thanks,

Lee.

Hi,

     I am working on CY8CKIT-042 PSoC® 4 Pioneer Kit.

     I would like to connect this kit to the external cap sense module. I have used all the GPIO pins available on the PSoC kit for taking the input from Cap sense but i still need two more pins.

     So, can i use P4.0 and P4.1 (which are for I2C communication) for taking the input from Cap sense? If yes kindly let me know because I have tried connecting these pins (P4.0 and P4.1) to the Cap sense but couldn't sense any value.

Thanks in advance.

Hi,

My environment

OS:windows10 64bit

PSoC Creator:4.2.0

PSoC Programmer:3.28.5

KIT: CY8CKIT-044, CY8CKIT-026

I want to use LIN and I2C　at the same time. However both communication use SCL(4.0) and SDA(4.1) port in example program. Can I use both if I use other ports as SCL and SDA?

Thanks,
