I am using FC 7.2, dsPIC33 ECIO with SIM900 module. I would like to send status and warning messages from my pool control via email, since SMS is limited to 160 characters. After I have expanded the control, I see that mail texts (body) longer than 250 characters are not sent. With SIM900 and termin...

Thank you, now I understand it! I have created an additional input, declare it as not a local copy, and pass the result at the end of this input string. This keeps the original string unchanged and it also works with the simulation.

Thanks for the quick reply!
Could you please show me how this works with parameter transfer? I have simple tools, which I always need again, packed into a component macro. Attached is a small example with the Replace function, but only works with short strings.

Thanks
Christina

Is it possible to set a return string of a macro longer than 20 characters? I am using Flowcode 7, latest version. Example: Search and Replace a Character in a String. I would like to use this function with some other string manipulations in a component macro. If I now want to edit strings longer 20...

Hi
Many thanks to LeighM and Benj for the quick solution! It works wonderfully!

Hi I am using FC 7.2, dsPIC33 ECIO. What I intend is that I send between 200 and 400 characters long strings over Wlan (ESP8266) from the PC to the MCU (and vice versa), which are then stored in the serial EEprom (parameters and texts). Attached is a transmission protocol and a short testroutine, wh...

Is it possible to send or receive a string with 400 byte or more via the RS232 (Wlan) interface?
I need this function to parameterize my circuit without having to split these strings.
Perhaps there is a simple way to realize this?

Christina

Thanks Ben for the quick reply.
I use the ECIO40P16, do not know whether it only occurs in the simulation. In my program I use for passing global variables since I had in the simulation of this problem.
Only 20 characters are possible in the Simulation.

Is it possible to create a macro with a return string up to 250 characters?
This function would be very important!

Thank you Ben for the many work, but the timer 5 works now! But my program still needs to be considered. In the function Chk_Switch, I activate the timer 5 and then I go to the keystroke. If the routine immediately enters the keystroke, the timer is not activated. If I disable the keystroke then it ...

Thank you Benj for the work. With the timer interrupts in the main program I have no problem, which runs without problems. The example that I have sent shows that a button is interrogated in the Chk_Switch macro (via Interrupt IOC port) and whenever the button is pressed, the status of port 1 is cha...

I use for my circuit an ECIO40P16, control and display of the periphery via a Nextion display and additionally print buttons for port on / off. Nextion and buttons are controlled by interrupt. Timer 1 accepts the cyclic tasks (polling the ports, switching date and time, etc.) If an override is to be...

I use the same module, the address of the AT24C32 is at 0xAC and 0xAD (A0-A2 are connected via resistors to VCC). So it runs with me without problems.
Enclosed is a section of an I2C tracer.

Thanks Ben!

One more question:
To which pins of the ECIO I2C is connected?
The Uart pins are remappable, but I2C have a fixed assignment (according to the data sheet of the controller).

Thanks!
Christina

Hello Benj,
Thanks for the quick and comprehensive response. I can then connect everything (GSM, Wlan, RTC) to 3.3V, for the Nextion display I take a level shifter.
Should I need an external I2C connection, then also over level shifter.

I have questions about ECIO dsPIC33.
Is it possible to get a dimension drawing from the PCB?
Are the pins 5V tolerant or only 3.3 V?
Can the MCU be programmed via ICSP with Pickit 3 or only via USB?
Can all Eblocks be used (LCD, Wlan, GSM ...)?

Thanks in advance for the answers!
Christina

Thank you Benj for the answer! It would really help if this function can be realized. It is much easier to check the routines on the PC under real conditions and then program the MCU.
I will first create a workaround to complete my program.

After I got no answer to my post, here again the question in short form:
Does RXINT work in simulation?

Perhaps someone can tell me whether in the simulation the Interrupt RXINT0 of the RS232 interface with Injector functions. This would be very helpful, I do not know whether I should continue to try to configure the interrupt according to data sheet.

The baud rate works with Nextion up to 115200. I have set 38400 Bd. With Bauds=38400 the transmission rate is permanently adjusted, runs fine. Sleep = 0 is needed because I have 3 minutes Auto Sleep. The 3x \xff \xff \xff are the end signal of a command via the serial interface. The functions of the...

I connected a Nextion touch screen to Com Port 1, the display is programmed so that every 5 seconds a query is made for changed data. In order not to reprogram the MCU every time, I have connected the display on the Com Port (USB) of my PC. Now I want to jump over the serial interrupt into my routin...

Thanks for the reply, Kersing!
Then I continue with macros.

Christina

Thanks for the answer! I've looked at everything I've found about component creation. I need a function, where I can pass parameters in the flowchart (as with a display or RS232 or similar), this example does not seem to work. The calculation is made when you enter it in the Properties window. The e...

I need a specific function for a project that creates a string of decimal or hex values from a delimited string and outputs the number of separators. Is it possible to create a component that returns these two values? I always get only a "return value". Has anyone ever tried this and can give me som...
