Hi,
The error what I was getting with respect to isr is solved now as I included _isr in the function name. Now the problem what I am facing is, the LPBACK option(loopback) which was working earlier with 8.3 version mplab is not working now with 8.87 version mplab. Earlier I used to get the...
Hi,
Ya I have gone through the data sheet of dspic30f controller for I/O ports. I am trying to read/write the latches. But PORTF and PORTG are not reading any values. Even though I set or reset the TRIS bits, PORTF and PORTG are not reading any values. Please let me know the reason for this...
Hi all,
I am using dsPIC30F6014A controller and I am trying to write a driver program to read/write the port pins. I am using C30 compiler. Since this controller has A,B,C,D,F,G ports I am writing a value to each port and trying to read the value written using functions for read/write...
Hi all,
I have resolved the previous problem that I mentioned by including libpic30.h supporting file in which all the registers were declared. Now I need to know the syntax of ISR to be used for dsPIC30F controller. I am getting the following error.
error: syntax error before 'isr'
The...
Hi all,
I downloaded C30 compiler for dsPIC30F controller and tried to build the code for UART. I have included pic30f header file but still I am not able to build it successfully. It is showing register bit fields as undeclared.
example: error: 'UARTEN' undeclared (first use in this function)...
Hi all,
Waiting for your response for my query.I also want to know if line feed(LF) and Carriage return(CR) are to be included in our coding for communication with hyper terminal and if so how to include it?? Please respond to all my queries as soon as possible. Waiting for response.
Thankyou...
Hi all/Betwixt,
I now need to implement UART Driver with DSPIC30F6014A. I have gone through the data sheet and the settings to be made. Can anyone please share the code for communication with the hyperterminal? This being a higher end development board does'nt need any connections to be made. I...
Hi Betwixt,
I have another doubt with respect to the pin diagram of MAX232 IC. The data which comes in through the T1IN(pin 11) is connected internally to TOUT(pin14) or to R1IN(pin 13) of the IC?Please clarify.
Thankyou

Hi Betwixt,
I have another doubt with respect to...
Hi Papunblg,
Actually the kit manufacturers have just supplied the kit and the connectors along with the debugger and adapter. There are no cables supplied. So I have myself done the soldering of wires by taking two DB9 connectors. I connected the PIC side TX(pin 3) to the PC side RX(pin 2) and...
Hi,
Oh that is so wierd. I actually have two kits with the same schematic on both the boards!!Here in this case if I am not able to transmit receive to/from hyperterminal, atleast the loopback should work as the swapping of connections does'nt make a difference in loopback right? But my pin...
Hi,
Thankyou Betwixt for this information. I wonder how the kit manufacturers have messed up the important connections! Really shocking. Now I can't use this kit for my project. I shall take MAX232 IC and try out by crossconnectiong the RC6 to pin 11 and RC7 to pin 12. I will get back if any...
Hi,
That was the schematic of the MAX232 which I got along with the development board. If according to what you say,the transmit and receive are crossed over,then how else can I rectify it?Because the IC is inbuilt and the connections are soldered with the development board,what other option I...
Hi,
I am checking if the IC is working properly. I checked the voltage between pin 16(VCC) and pin 15(GND) and it read 5V. Now I want to check the capacitors voltages but I don/t know the ranges and I am not able to get information about it. I am using MAX232CN IC. Please tel me the voltage...
Hi,
Linking MAX-232 at the PC side is nothing but shorting pins 13 and 14 right?When I tried it I am not getting data reflecting back from TXREG to RCREG. I am doubting if there is any problem with the MAX-232 IC. Because I have read many posts which tell this IC would fail after many hours of...
Hi,
I have a doubt regarding the pins13 and 14 of MAX-232. Pin 13 actually is the input pin which receives serially transmitted data at RS 232 logic level; connected to transmitter pin of PC serial port and pin 14 is the output pin which outputs the serially transmitted data at RS232 logic...
