PSoC™ 5, 3 & 1 Forum Discussions
I want to get information from the slider on the touch nextion screen to psoc. I connected Nextion with UART to PSoC.
For example, if the slider value is 25%, how can I transfer it to PSoC?
Show LessHello,
I've just bought a PSOC5-LP and I'm interested in testing the glucose meter project.
Where can I download the source code project?
Thank you!

Hi,
Recently I used example code ot check how USBUART CDC works, but I can't connect to COM Port. I've got an error. Changing USB port and restart computer also not fix that issue. It's seems to be Microsoft Error. As I was able to establish usbser.sys block this COM port, but I don't know how to unblock this port. Any suggestion?
Thanks for helping.

Hi,
My project is about making a full-duplex communication between PC and uC (microcontroller). At the uC I have to make a simple wave generator which allow user to chose a few signal type like: sinus, triangular, saw etc. When I will do that I have to convert the signal by ADC converter and pass them to USB port.
The usb port have to be fast, because we have sampled signal. If any sample will be lost, I can go ahead - so I think its good choice to use ISOC Transfer, but the USB also have to provide changing signal attribute, like amplitude or phase, or even change signal type from sinus to saw. To make it possible I want to use second endpoint - control transfer.
Summarize, I have
- first endpoint - CONT Transfer - 16 bytes buffor - use to changing signal type
- second endpoint - ISOC Transfer - 64 bytes - using for transmitting signal samples
Everything has to be connected with desktop app build with Java and JavaFX to give user simple interface to control and see current signal on board.
I have problem with USBFS. I configured usb descriptors like below.
I don't know why, when i plug my psoc 5LP to my computer sometimes it's works, and sometimes not.
Thanks for helping

They are all 24-bit data(or multiples of) with a clock and data on positive or negative edge triggering
-
There is a gap between data packets that is orders of magnitude greater than the clock to distinguish start.
Hi,
I have problem with connecting with my USBUART port. I restarted my computer. It is still the same. Do you have any suggestion? How can I debbug that?

Hello
It would be very helpful if you could answer as soon as possible.
I am using a CY8C24123A device.
Since the project created a long time ago cannot be opened with the latest version of PSoC Designer, a message was issued to open it with a version earlier than Ver4.4.
When I built the project with version 4.4, the message of the attached image appeared and I could not build.
●Why is this happening?
●Is there a solution to the problem?
Best Regards
Haya

Hi all,
i am a little confused regarding the supply concept of a Psoc5 CY8C5888AXQ-LP096100-TQFP and have a question regarding the supply.
In the data sheet of the psoc i have found a figure for an example schematic for a 100 pin TQFP part with power connections. In our application we have a DC/DC converter for a supply voltage of 5V. Regarding the supply i have come across the regulated and unregulated mode of the psoc. Due to our 5V supply, as far as i understood i have to apply the 5V to all the VDDx (VDDio,VDDA and VDDD) of the PSoc in order to use the unregulated mode. In this case, i dont have to supply the VCCx pins, but i have to connect both of those without any supply. Can someone please confirm that this consideration is correct? How does the Psoc "know" that im using the internally unregulated mode? Do i have to do any further settings in the Psoc Creator itself, or is this mode recognized automatically by the Psoc MCU?
I also saw pins for VBAT/VBOOST. As far as i understood those are for powering the Psoc with an integrated boost converter in order to supply the psoc with a single cell battery or something like that. Since we have a DC/DC converter, we dont need those pins. My problem ist, that in the example schematic the VBOOST, VBAT and VSSB pin are simply connected to ground, but in Figure 6-7 of the Datasheet (Application of Boost Converter not powering PSoC device) there is an external circuit with the note, that all components and values are required. Since we are not using the internal boost converter and a supply voltage connected to VBAT, is it enough to simply connect VSSB,VBAT and VBOOST to ground as shown ine the example schematic?
Many thanks for your help.

Hi,
I've been trying to make a hardware based boost converter using PSOC5 but it isn't working. I have attached a picture of my hardware configuration.
The PWM's period is 21.333us and the listed sampling rate of the ADC is 100000, giving the system about 10us of time for the system to complete the DMA and trigger the interrupt along with running a few lines of code. However using the debugger the interrupt runs either only once or not at all. I know it at least has been set up properly because it can be triggered.
I have attached the project below and am hoping someone might have insight as to why it is not repeatedly triggering.
Any help would be appreciated
Show LessHi,
We are looking for a customized microcontroller for PLC communication or a PLC integrated circuit compatible with our existing microcontroller and topology in our New Generation 25-33 kW Solar Inverter products.
In our new generation solar inverter product of 10-25-33 kW, which is the subject of this meeting with you, we are planning to use 50 measurement units for 100 PV panels, each of which will measure 2 panels and transfer them to the PLC line.
We request your opinions on whether your PLC solutions will enable the electrical measurements of each of the 16 serially connected PV units that we aim in our product to be able to transport to the central inverter with 800VDC (1200VDC max) via PLC.
In each communication module, communication signals must be coupled serially on 12A DCmax current and the signals must be read over this line. In this way, 3-4 strings are connected in parallel and connected to the inverter's DC bus. The total current in this line can also be 50A DCmax. It is not necessary for the communication unit on the inverter to be serially on the power line.
There are buck output capacities connected in parallel to the output of each module. (this is important to know the high frequency path)
In the current design we are taking a few measurements from PV units by using some electronic equipments which creates
-15 Khz Switching Signal
-100 Khz Switching Signal
-50 Khz Switching Signal
switching noises over the PLC line.
We would like to further find out if your company's PLC microcontroller solutions have filtering solutions that can communicate uninterruptedly between such switching signals.
The data to be read from each measurement point is around 20 bytes. Data will be requested from each communication point at the most frequent 1 minute intervals. However, the request response with a period of 1 second will be found continuously on the system. Communication is 2-way, from the inverter to the measuring points.
