PSoC™ 4 Forum Discussions

Hello,

if I search for this kit a lot of documents are still available but not the kit files.

Where I can download the EXE or ISO file for these kit ?

Regards.

I found the top mark of CY8C4025AZI-S413 are totally different in logo and text format as you can find in the attachment,is there a PCN doc to clarify this,or is there any doc to explain this?thx

Hi,

I am testing die temperature with CY8CKIT-041-41XX board with single ended negative input equal to VRef.

No work well (Wrong values) when I change single ended negative input to VRef:

#define DIETEMP_VREF_MV_VALUE 1200

#define DIE_TEMP_GET(x) DieTemp_CountsTo_Celsius((((int32)x * ADC_DEFAULT_VREF_MV_VALUE) / DIETEMP_VREF_MV_VALUE))

AdcCh = AdcGetVal( ADC_CH_6, 1 );
TempDie = (int16)DIE_TEMP_GET( AdcCh );

Do you have a solution ?

Best regards

Hi.

Please tell me about the offset voltage of the PSoC4200L OpAmps.
In the datasheet, the offset voltage and the offset voltage drift values are listed.
However, the values of min/max and typ are defined only for high mode, and for medium and low  modes, only the typ values are described.
What are the min/max values for these modes?

Regards,

Dev-board : CY8CKIT-149
IDE : PSoC Creator 4.4

Hi, I’m using touchpad(metal mesh sheet) and trying to detect short defect by shorting two GPIO Pin connected with electrode.The capacitance value of the shorted pin is theoretically twice the normal value, but 40 times the normal value is detected.And its 40 times value is constant at 854375 (In general, capacitance value should shake out a bit).

Something is wrong obviously.I have got a few ideas.

Regarding to “PSoC® 4 and PSoC 6 MCU CapSense® Design Guide ‘3.1 CapSense CSD Sensing mode Figure3-1), when using CSD mode, a GPIO pin may serve as an output as well as an input (if both are outputs, there will be a conflict).

When I disconnected the Jumper wire from the electrode and shorted the pin on the dev-board, the constant value was detected as well, so the problem must be on the board side.

For example, I shorted P2_2 and P2_1. Any other combination would have the same result. What’s strange is that sometimes pins that aren't shorted act like they are shorted. When the Pin is not shorted, it measures normal values, so it is unlikely that the board is broken.

I share the project. Please teach me what is wrong with it and how to accomplish my purpose.

Thank you.

Dear Receiver,

I am testing PSoC4 I2C Master and Slave sample code.

I understand Master_Read, Master_Write, Slave_Write and Slave_Read from sample codes which are provided by PSoC creator 4.4.

But above sample codes are all for polling type.

I can't find sample code for slave receive interrupt.

Could you please help me to get a I2C slave interrupt (master - > salve, and slave interrupt immediately not polling ) sample code ?! 

Thank you so much.

I'm a beginner, and I've been assigned a project to enable an OTA FW update for PSOC 4 BLE boards via an iOS app.  There are two different boards shipped with two different PSOC 4 BLE  parts on them: CYBLE-224116-01 and CYBLE-224110-00.  The present FW on the units is not equipped with functions to read the the PSOC part IDs to differentiate them during flashing.   The test units I have do not have recovery pins exposed, so flashing FW compiled for the wrong part could brick the unit.  I need confirm the bricking behavior. Will the unit become inoperable without recovery or will the FW flash simply fail due to a check in the flashing code and leave the running FW in place?  If its the second one, I can simply retry with a FW file for the other unit since there are only two possibilities.

Hi ! I'm experimenting with CY8CKIT-149.

I'm using  CSD sensing method or CSX  sensing method to measure the capacitance value on touchpad.

I shorted two GPIO Pin to simulate short defect. In this case, the two shorted GPIO Pins theoretically indicate double the normal value.

But, it was observed 40 times as large as the normal value and constant at 84537 fF measured by the function CapSense_GetSensorCapacitance().

I don't know how to observe the double value.

Please help me.

Hello,

I am working with PSoC-4 and want to know what is the PSoC-4 boot time. How much time it take for executing the first line of main() upon power-up. I could not find this data from Cypress website. 

Please help.

Thanks,
