PSoC™ 4 Forum Discussions
Hello,
I am using a thermal printer via UART, and I need to send ASCII extended characters to printer. The function that I used to send is UART_PutChar. Is there any way to send characters like Ç, Ã or Ê? PSoC marks these characters as a warning and the printer prints wrong characters.
Thanks in advance
Show LessHi I'm trying to use I2C in CYBLE-212019-00 module and I want to use 500Khz for SCB0_SCL
Does CYBLE-212019-00 support 500Khz I2C?
And I wonder Mater - slave switching is posible in one I2C
Show LessHello, I am struggling on the PSOC4 deepsleep. 0xFF is received when wakeup source is not UART. I find the UART low power note in the UART component datasheet.
0xFF is gone after applying this workaround. But I have to add more preamble bytes before the real data. It is very inconvenient.
Is there a solution or workaround to resolve this issue better?
Show LessHi Expert,
We use your PSOC4 Capsense make a product for liquid level check, we found the the test is not good when the plastic box wall is bigger than 2mm thick. There are only 0.5% rate of ADC value changed. But for little thickness(<0.5mm), there are 10% change rate of ADC value .
We have below questions?
1. What is the max thickness of plastic box wall for this Capsense liquid level test.
2. Can we get a design to satisfy this bigger thickness liquid level test with tuning the Capsense sensor pad bigger or other trick?
CY8C4246AZQ-M443 + Capsense CSD mode.
Show LessWhat happens is that I tried to use EmEEPROM with PRoC and it showed me that it was not compatible with PRoC. Then I would like to know how to use FLASH as emulated eeprom.
Show LessIn a PSoC4 BLE project I setup the Device Name in the BLE configution screen, GAP Settings, General, Device Name to be "LBE-5A" (without the quotes). I built the program and programmed a Device. Using an iPad app I observed the device to be advertising the name correctly.
Next, I changed the name in the same location in the BLE configuration screen to be LBE-5A-100. After building and programming the iPad app showed it to be advertising the same as before (LBE-5A) without the -100 part.
Do I have to do something other than clicking OK in the configuration screen, rebuilding and programming the device for this to work?
Thanks,
Dennis
Show LessI have a CY5677 CYSMART BLE 4.2 USB Dongle and a CYBLE-214009-00 evaluation board.
I am trying to use the USB dongle as a uart-ble bridge to communicate with the CYBLE-214009 through a serial terminal. When I type a character in the serial terminal, the usb dongle should transmit that character to the cyble-214009 and the cyble-214009 should in turn send continuous sensor data for about two minutes.
Would it be possible to use the 'UART to BLE bridge peripheral' project to program the usb dongle, and edit the 'UART to BLE bridge central' project to program the CYBLE-214009 to send sensor data over BLE through UART? What changes would I need to make?
Show LessI'm starting to doubt whether this is even possible. I'd be grateful if someone could tell me if I'm wasting my time:
i have created a custom PCB using a PSoC4 BLE module. I plan to have some number of these same units within the BLE operating distance of a similar number of iPads. I want to be able to pair/bond/connect a given iPad to one and only one of these peripheral units and each unit be able to connect to only the one iPad.
The ipad will be running an app specifically designed for this and will include a provision to specify which peripheral unit to connect to.
I've tried using different local names in each peripheral which works fine when only one peripheral is advertising but when two or more are advertising the iPad seems to not care what the local names are and will sometimes connect to the one with a different local name.
Is this a place to be using PSoC's public address or what should I do (if it really is possible to do this)?
Thanks,
Dennis
Show LessI remember reading that setting up a PSoC 4 BLE as a peripheral for an iPad (iOS device) needs certain parameter values as required by Apple, but I can't find this information. Can someone please direct me to it?
Thanks,

Show LessHello,
Can anyone explain why if we place a PSoC 4 BLE (CYBLE-224110-00), without respecting dimensions of the host PCB-keep out area, can lead us to an unacceptable BLE connection distance (RF-BLE connected at maximum 5cm RF from Tx)?
Based on Cypress datasheet "002-11264_CYBLE-224110-00_EZ-BLE_TM_CREATOR_XT_XR_MODULE.pdf" we have
Based on our board design we placed the antenna part of PSoC at the edge of host- PCB
What is the purpose of host PCB-keep out area concerning BLE RF propagation?
Keep in mind that we have an efficient VDD and VDDA in PSoC and also TX Power ,TXP, 0dBm!
Can this issue (the violation of respecting dimensions of the host PCB-keep out area for best RF perfomance) justify this unacceptable BLE RF connection or could be something wrong with other thing (bug)?
Thank you in advance
