Hello Ben,

I am using 33FJ32MC204 and it has remappable peripherals. I am using Flowcode 6.0.7
It is not possible to remap the TX and RX pins in hardware channel.
When I try another dsPIC33 I can remap the TX and RX pins.

Hello Ben,

How can I connect the Tx from the RS232 to another port on a dspic33. The Tx is now connected to portB.6 and I want to connect it to portB.9
I am using V6.

Thanks, Marcel

Hello Ben,

The RXint2 is working like I suspect. So that problem is solved. But the next problem is already there. I like to use a timer interrupt to sample a signal on my AD pin. But this interrupt routine seem to have the same problem. In simulation it works fine but in the PIC it doesn’t work ...

Hello Ben,

YES, now the interrupt on RXINT2 is working. I need now further testing.

Thanks for your help so far.

Hello,

I have test the program but the interrupt will not start. Is there a possibility to test the interrupt?
Is it possible to give an interrupt on RX2 instead of RX1?

Thanks, Marcel

Hello Ben,

I'am still struggling with this, the program is not working.
Do I need to fill in a return value in the component macro UART 2 Receive Byte ?
I have attached the new program.

Hello Ben,

At the end of the c code there is this warning "This interrupt has previously been enabled, so the macro <rx_uart> may never get called."

Hello Ben,

If I move the sendRS232 macro into the next while loop, I receive nothing.
I have attached the program and the C file.

Hello,

In your example I have the 5 sec. delay replaced by the UART-1 for transmitting data, I read data by UART-2.
I only receive 00 00 ...... 00
I think the interrupt will not start, it's not working. Maybe you could help me.
Thank you.

Hello Ben,

I have put your cicular-buffer v5 in v4, but it will not work. Maybe I'm doing something wrong.
I have attached the program. Could you please look whats going wrong.

Kind Regards.

Hello,

I’m facing a problem with reading data from a serial sensor and sending the received data through. with a serial bluetooth module. I’m using a PIC 18f6722 and Flowcode V4.
I connect UART 1 at a bluetooth device and UART 2 at the serial sensor. The sensor send continually data. It sends 3 ...

Hello,

I have a LinkMatik bluetooth module from FlexiPanel. How can I set up this module as a generic serial communication bus, same as the Ezurio bluetooth module. Can I program it with the example 1 program from the bluetooth bundle ?

Kind Regards, Marcel

Hello,

Thanks Ben now it's clear. But.....If I have a variable of type Byte, why do I see in the RS232 Macro: Return value: (INT).

Thank you, kind regards.

Hi Ben,

In my program I make a calculation: income = Idx. Do I also change Idx in a INT type variable ? It's now a Byte type variable.

Thanks.

Hello Steve,

Do you mean char receive type "Int" and the data bits remains 8 ?
In the decision box should I fill : income <= 255 ?

Thanks.

Hi Nicolas,

The program is working now, Also when I program it. Thank you very much for your help.

I have another question, I would also like to receive hex number FF (255)
In the decision box I fill in: income <= 255. It works but is it allowed?

Hi Nicolas,

Thanks for looking at my code. I have add the while loop, but it would not work.
When I simulate it, its going wrong at the decision box. Also when I program it I see nothing.
I have attached the new program. Could you please look whats going wrong, Thanks.

Thank you very much for responce.
I have tried it but I don't know how to implement it in my program. Maybe you could help me.

Thank you, kind regards

Hello Ben,

With this program I have attached I can receive and sent the hex numbers that are comes from my sensor.
But I receive a lots of data that I do not all needed.
The problem is I only need the first 15 bytes when byte[2] has the hex number 81 or 83 or 87.
I am still struggling with this and ...

Hello Ben,

I now have a program that shows de Hex numbers of my sensor. I would like to read this data (in Hex) and stores into an array. Is it possible to stores the Hex numbers into an array ? And how could I received(send) Hex number FF ?

Kind Regards.

Thanks Ben,

Do I need the incoming RecieveRS232Char change to RecieveRS232String ?

Kind Regards.

Hello,

I have a uC with 2 uarts. I have a sensor and this sensor send HEX numbers to the RS232 (Tx,Rx) input.
How can I see these HEX numbers on my PC with hyperterminal ? I see only the ASCII codes on my PC.

Thanks, Marcel

Hello,

How can I programming a 64 pin PIC ( QFN ). I have a EB006 multiprogrammer.
