SerialPlot is a custom component for interfacing with real-time plotting software SerialPlot.
Hackaday.io: SerialPlot - Realtime Plotting Software
The component implements interface to the real-time charting software SerialPlot. Using this component, PSoC data can be easily visualized on personal computer (Linux, Mac & Windows). Component doesn’t consume hardware resources, performing all operations by CPU, which is useful for systems with little resources, such as PSoC4. Multiple instances of the component can run simultaneously in the project.
Component features:
Data types: int8, int16, int32, uint8, uint16, uint32, float
Up to 8 channel output
The component was tested using CY8KIT-059 PSoC5 prototyping kit and CY8KIT-042 PSoC4 Pioneer Kit. Demo projects are provided.
Attached archive contains component library (v0.0), component datasheet and demo projects for PSoC5 and PSoC4. Please read installation instructions in the readme.txt.
The component provided as-is, no liabilities. It is free to use and modify.

Dear /odissey1-san,
Although your component seems to be nice, my brain is not functioning well.
May be, because it's Monday.
Anyway, I extracted zips as below
Then I opened Demos/SerialPlot_basic_01a.cydsn/SerialPlot_basic_01a.cydwr.
When I tried "Clean and Build" I got
Then I opened Demos/SerialPlot_P4_basic_01a.cydsn/SerialPlot_P4_basic_01a.cydwr.
When I tried "Clean and Build" I got
Apparently, I'm missing some step(s), would you teach me how/what to do?

Dear odissey1-san,
I'm sorry for being messy but...
well, first the good news is your library and demo seems generating right data
(1) Recorded log (numbers seems to be fine)
next the bad news is my plot does not look like yours ... orz
(2) Data Format Tab
(3) Plot tab
I wonder if my plot tab is appropriate.
Could you show/teach me your Plot tab setting?
Best Regards,

Motoo,
I downloaded an tested your project SerialPlot_P4_basic_01a on CY8CKIT-042 (Pioneer Kit) using Creator 4.2. Everything seems to be OK, the output is below. Attached also SerialPlot Settings_01.ini file.
Can you please switch the Component output format to ASCII and check with TeraTerm or Putty what data is being generated by the project?

Dear Odissey1-san,
Something just came to mind.
I grubbed another CY8CKIT-042 from our lab stock.
And tried with the same project.
So I realized that my CY8CKIT-042 was broken or at least sick as its output was still
Then another thing came to my mind.
So I started the PSoC Programmer and updated the firmware of my CY8CKIT-042.
Then the output was
After all, the problem was the old firmware on my CY8CKIT-042 (KitProg).
I'm awfully sorry for disturbing you with this.
But next time you see the above middle screen you can suggest your customer
to update KitProg frimware.... orz
Anyway, now I (think that I) am fine.
Thank you very much!
Best Regards,

Attached below is a new version v1.0 of the SerialPlot component for interfacing with real-time plotting software SerialPlot (0.12.0).
What's new in v1.0:
* The number of output channels increased to 64
* Option to send multiple data packets per frame
* Added procedure PlotArray() for large number of channels
* Full compatibility with PSoC4 SCB UART
The component was tested using Creator 4.0 and 4.4 using CY8KIT-059 PSoC5 prototyping kit and CY8KIT-044 PSoC4200M Pioneer Kit. Demo projects are provided.
Attached archive contains component library, component datasheet and demo projects for PSoC5 and PSoC4. Please read installation instructions in the readme.txt.

Figure 1. Example of SerialPlot Bar Chart plotting of 32 channels of data using Chart_PlotArray() API.
Below is a demo project showing high speed data output from PSoC4M to the SerialPlot charting software. The SCB UART is configured for 2Mbaud rate using external clock of 16MHz (48MHz/3), with oversampling ratio of 8.
To achieve such rates, an external USB-UART converter has to be used, as the KitProg's USB to UART converter maxes out at about 115.2 kbaud due to the clock inaccuracy. An FTDI converter cable ( TTL-232R-5V-PCB) was used for this purpose.
The test data (2 channels of int16) were generated at about 9kHz rate and sent to the SerialPlot charting tool using the SerialPlot v1.1 component. Project essential code:
int16 v1,v2; // data channels
...
for(;;)
{
if(isrTimer_flag != 0) // monitor for Timer interrupt
{
isrTimer_flag = 0; // reset flag
GenerateSignal(); // update values v1-v2
Chart_1_Plot(v1, v2); // plot values
}
}
Full project description provided in the component datasheet (Appendix 5).
Figure 1. Project schematic. The SerialPlot component is configured for 2 channels of int16 data type, Custom Frame format, with the Checksum enabled. The SCB UART is configured for 2Mbaud rate using external clock of 16MHz (48MHz/3) with with oversampling ratio of 8.
Figure 2. Component Advanced settings. To reduce the amount of the overhead bytes and to lower the SerialPlot refresh rate the number of data packets per frame was set to 32. The FrameSizeFormat parameter was set to automatic (first byte is a payload size).
Figure 3. Project annotation using KIT-044 v0.2 annotation component. The external USB-UART bridge is directly connected to the SCB UART output Pin_4[1]
Figure 4. SerialPlot output and Port settings: Port: COM6 USB Serial Port; Baud Rate: 2000000;
No Parity, 8-bits, 1 Stop Bit, No Flow Control. The non-standard Baud Rate value must be typed
into the dropbox manually. The data packets rate is 8885(4 bytes each) per second.
Attached is v1.2 of the SerialPlot component for interfacing with real-time plotting software SerialPlot (0.12.0).
What's new in v1.2:
* Option to use USBUART interface
The component was tested using Creator4.0 and 4.4 using CY8KIT-059 PSoC5 prototyping kit and CY8KIT-044 PSoC4 200M Pioneer Kit. Demo projects are provided.
Attached archive contains component library, component datasheet and demo projects for PSoC5 and PSoC4. Please read installation instructions in the readme.pdf.
