  1. A really basic question this one. I wish to have RA0 on a PIC16F877A as the only active ADC, all the rest should be outputs. How do I do it? Conrad Forgot to mention that Vref will be Vdd and 0v will be Vss.
  2. I have a VFD module that I would like to use with a PIC16F877A. The VFD in question is this one Noritake VFD module data As far as I can see I should be able to just use the TX pin (RC6) of the PIC, GND and Vdd, set the baud rate on the PIC and the module to be the same and that should be that. Does anyone have any working code? Thanks Conrad
  3. How soon will this be released Dave? I could really use this facility now I have all the support hardware for my Uni project done now apart from the PIC programming. This needs the most time as I am an inexperienced PIC programmer to say the least. As usual time is running out. Until I can get some code that will allow me to use the display on my PICDEM 2 PLUS I can't proceeed. There is an asm file that came with the demo board that I could use but I'm unsure how to go about using it in conjunction with C code. Conrad
  4. I have just changed programmers from the matrix multimedia PPP parallel port programmer to ICD2 and wondered how I should set up Source Boost to accomodate it? Thanks Conrad
  5. I am struggling to understand (it's early days) how to configure the Ports for LCD libraries. My intention eventually is to use a PIC16F877A and an LCD in 4bit mode. If I load boost4bit.__c project and I want to use the SourceBoost LCD plugin how should I configure it? I mean what ports? I can see that trisa is set to outputs and that #define LCD_E 0 #define LCD_RW 2 #define LCD_RS 1 I cannot however figure out what I should set DB4,5,6 & 7 to on the plugin. I know that DB0, 1,2 & 3 should be Vss in 4 bit mode. Initially I can experiment with a PIC16F84A but I h
  6. I have verified that the LCD is ok as I have it displaying some text. So I wonder what the problem could be with the FMesure project? Does anyone have any ideas? Conrad
  7. Hi Dave well I 'thought' that I had done what you suggested, yet when I looked at the unzipped folder it appeared to have some extra files in it. In hindsight I think that I must have tried to compile Lcd6Pin first. Anyway I unzipped the folder to a different location and all is ok with the compiler. Now the problem is that I can't get the LCD to work, it is definitely wired correctly, the datasheet suggests that it is pin compatible with the one shown on Gerard Burger's schematic. My LCD uses a KS0070B controller IC. Any ideas? Is there something I could use as a quick check to see
  8. Hello I am having some problems compiling the FMesure program listed as an example from the SourceBoost pages. click here I am using the SourceBoost IDE but I confess to being new to the program. Presumably if I unzip the files and make sure that lcd6Pin.c and FMesure.c are included the project should build, link and compile ok. I get lots of errors such as the code below indicates. I am using C2C plus toolsuite with the matrix multimedia PPP parallel port programmer, although I think should be obvious from the output window code :-) Please help! Compiling... C:\PROGRA~1\S
  9. I have been using the version of C2C that is supplied with the Matrix Multimedia PIC development kit but I needed to use a PIC16F877A and so upgraded to the SourceBoost package. The SourceBoost IDE has loaded sucessfully and I have sucessfully registered my password for both SourceBoost and C2C plus using the command line prompts. The problem is that there is no sign of the c2cw.exe program that appears in my Matrix multimedia directory. I did not uninstall the Matrix multimedia version of C2C so perhaps this is the problem. Can someone help please as initiallt I would like to cont
  10. I have a design project at University which is basically to make a handheld X band Doppler 'speed gun'. The basic requirement is to build something that will acquire and display speed in mph or kph with a range of 10-150 mph, an accuracy of +/- 1mph and an acquisition time of 0.5 seconds. It must be able to detect a moving vehicle at a distance of > 20m. I am to be supplied with an X band Doppler module which has a low noise amplifier fitted. The module has a WG16 flange for the connection of a horn which I also have to fabricate. I have calculated that the mixer diode output will be be
