Hi Kenrix2, I tried your SW key and finally without stack corruption error so thank you again for this. Maybe i didn't save the compiling options. Also You are write again why make it too difficult I will follow your advise and make a bypass When certain commands are missing I send them afterwards v...

Hi Kenrix2, You got no error message like this in your compilation? Serious Warning: Possible sw stack corruption, function 'FCD_RS2320_ReceiveRS232Char' called by more than one asynchronous thread (main/Task, interrupt, interrupt low) Serious Warning: Possible sw stack corruption, function 'FCD_RS2...

Hi Kenrix2 Thank you for willing to help me . Yes, your write. But I need a micro with 2x PWM for the motorcontrol and 2 Usart for communication. Then you need soon the Pic18F..K.. models. This series mcu is not programmable with the E06 programmer board. I know it has to be possible to do this with...

Is there anyone who has experience with the use, in the same program, of a hardware Uart and a software Uart from the PIC16F877A for reading, editing, and sending data of a RS232 device to another RS232device? I've been a long time experimenting. Now I notice the following warning messages in the co...

Hi benJ, No I haven’t a scope or logic analyser. The only thing I can do is to use the program Micterm. With this program I monitor the RS232 signals. I fully agreed with your assumption that the interrupts do not works like they have to do. For that I tried to don’t use the interrupt on port B and ...

Hi Benj,
Finally succeeded to load the Visca protocol file.
Do you have any idea why the camera messages cannot be read through portB?
Beejo

Hi Benj, I am very glad that you are willing to have a look into my program. First there is one Pic16F877A that intermediates between a controller and a camera and controls a Pan & tilt head via an L273D chip. The controller can send “Visca” commands to adjust an Pan & tilt or gives “Visca” commands...

Hi Benj, Thank you. Yes i can use the nice work around because i have still a lot of problems to build a rs232 communication on a pic (eg pic16F877A) between a controller and a rs232 device. I am trying to make one connection on port C to the controller and one connection on port B to the device Usi...

Hi,
Can i monitor the RS232bus using the RXINT interrupt with Flowcode V6?

Beejo

Hi Benj, I think I have done what you told me but in simulation mode the interrupt does not work. I am not sure about where to place the enable interrupt in the program. I have the feeling it have to be done before the while-1 command in the main prog. I enable the RXINT interrupt before the While-1...

Hi,
I try to solve the problem to read an command in a reliable way by the RS232 in Flowcode4.5 prof.version. Maybe by making use of an RXINTInterrupt. BenJ gave this clue. I try several times but The Interrupt is also not working.
Someone can help me???
Beejo.

Hi Benj, Thanks that you are willing to help me. I have to use: hardware UART, 3wire RS232 bus, 9800baud, 8 data bits and no flowcontrol. I have no experience with Interrupt Handling. Can you show me how i can use the RXINT interrupt to read the bytes at a time? Maybe with a example? And what do you...

Who can tell something about design rules concerning Servocontrol, receiving RS232 strings, the use of the internal Eeprom and the use of an LCDdisplay in one Flowcode-program of an Pic 16F877A controller? Because for a long time I run up against unexpected results of servo moves and not received co...

Hi Benj, I disabled the servo’s before any read or write action of the EEprom. The result is that the Receive program accept all the commands except the stop-command. This is a really nice thing but only the Stop command is not always seen by the Read-RS232routine. I notice when the timeout value of...

BenJ,
That sounds great i never came up on that link. Tomorrow i shall try this in simulation mode and next monday in practice. Because i am not in the office till monday.
I inform you as soon as I know something more about it.

Beejo

Hi BenJ ,

I have send you two pm's with the programs enclosed.

No, only the RS232 module from flowcode. I don't know if they make use of a interupt routine.

Hi, I am trying to use the RS232 module in Flowcode 4.5 to receive commands in a PIC16F877A(“The receiver”) and to control two servo motors. To test the program, I use two EB006 PIC program boards. One to control the servo’s as an RS232 Receiver or to use as an direct Hand-control (5 switches), call...

Hello Benj, After disabling the servo’s in the program, the motors don’t react on a reset and that is good. Only when you power up the system they start up with a wrong pulse. The motors do the same thing with power up after disconnecting the signal wires from the PIC. So the disturbance doesn’t com...

Hello Benj,

Thank you for our proposal I change the program as soon as possible and let you know the result.
Regards,
Beejo

Hello Benj, The PIC16F886 was already loaded with software and i hope with the same version than i get on CD. The writer says that the versions on CD and on the PIC are the same. So I sent herewith the latest version from the CD. The file is an .bas file and this extension is not allowed to send her...

Hi Benj,
I am glad that you ask it. Here it is.

Beejo

Hi Benj, The motors make his movement just after i released the reset button. There is nothing happened as long as I push the reset, but on the moment I release the knob the motors makes the swing. I have to say that in the ICD mode, with step for step debugging, the first reaction comes from the Pa...

Hi Benj, Thank you for your quick answer friday. I put one Set Position macro direct below the begin statement. Than the enable Pan Servo macro direct below and the same for the tilt servo her under. It gives indeed an improvement with a minimum of 50% Instead of a linear disturbance movement of the...
