PSoC™ 4 Forum Discussions
I am using PSoC Creator 4.2 and trying to build my project, but am running into the issue "Unable to find component cy_boot_v5_81". I tried to update update the components, and in the Component Update Tool I see that my current version of cy_boot is 5.81 (Unknown), and the new version in the program is listed as 5.70. How can I update the new version in the program to 5.81?
However, the accepted solution did not work for me. Please let me know how to fix this.Show Less
Is it possible within the Observer example project to continuously scan a single BLE advertisement channel with absolutely no time gaps missed due to any "interval" or "window" setting?
If so, will the PSoC 4 module be able to transmit the advertisement data out of its UART while simultaneously continuing to scan the single advertisement channel and receive another RF advertisement packet?
I don't care about power. I am simply looking to implement a single channel sniffer which performs GFSK demodulation and relays any received advertisements from any clients out of its UART in real time.Show Less
Dear Sirs and Madams,
Please tell us how to use the ”Cy_SCB_I2C_MasterSendStart()" API of I2C interface.
The waveform when the function "Cy_SCB_I2C_MasterWrite (CYBSP_I2C_HW, & masterTransferCfg, & CYBSP_I2C_context)" of I2C Master.c is used is as follows.
ACK has also been confirmed, and communication is successful.
When We change this function Cy_SCB_I2C_MasterWrite() to Cy_SCB_I2C_MasterSendStart(), the waveform never appears and the SCL is fixed at 'L'.
API that is working normally before the change:
Cy_SCB_I2C_MasterWrite (CYBSP_I2C_HW, & masterTransferCfg, & CYBSP_I2C_context)
API that does not work properly after change:
Cy_SCB_I2C_MasterSendStart(CYBSP_I2C_HW, I2C_SLAVE_ADDR, CY_SCB_I2C_WRITE_XFER, 1000000UL, &CYBSP_I2C_context)
I configured it with reference to PDL, but is there a problem with how to use this "Cy_SCB_I2C_MasterSendStart()"API?
One of Our customers requested above application guilde.
First, I tried to build of myself.
But I faild because there is no archive files named 'OTA-required-files.zip' in page 16
I attached the guilde application note.
Please support that issue to solve.
Dear Sirs and Madams,
I know that PSoC4S has SAR ADC( 12bit, 1Msps).
Does overflow or underflow occur when the input to the ADC is VDD or GND?
I confirmed for the component data sheet of SAR ADC, but it was not mentioned, so I am checking it in this community.
Although the ADC is 12 bits, it is estimated that it may occur because the data handled by the conversion output is 16 bits.
In that case, it is necessary to correct the data by software, so please confirm it.
We are making security improvements to our OTA FW process. We are exploring the option of configuring FW to trust a set of public CAs and required a FW update to be signed by one of the supported CAs. I'm looking for similar projects, but I don't see anything yet. Is there a good example out there?
If this is not the process people commonly use, is there a better approach to verifying FW images are trusted?Show Less
PSoC4(CY8C4125LQI) WDT counter works normally if device is powered on, but WDT counter does not work normally at debug mode.(device is not reset)
Does not WDT counter work normally in debug mode?

I am really struggling to implement a fixed duty (50%), variable frequency pwm output (controlled by a pot). - I am trying to generate a variable (+modulated) clock frequency for an external chip.
The only way I seem to be able top do it is by adjusting both the period and compare (as period/2) simultaneously, which feels a little clunky.
would anyone have any other suggestions how this could easily be done?
Any pointers how this might be done would be greatly appreciated.Show Less
I am using PSoC4 CY8C4247AZI-M485 to measure 8 currents and i also want to measure a thermistor. I can not seem to get PSoC to build this is there another way I can do this?
