I am interested in attempting to write some code for a MIDI controller for a keyboard or guitar. Has anyone done this or know anything about it? I have never worked with MIDI codes and know very little about it. If anyone has done anything in FlowCode concerning MIDI, I would love to see some ...

I am having a problem with my LCD. I am using a 20x4 Display and am able to print to it fine.
The problem I am having is that the cursor wraps line 1 > line 3> line 2> line 4 > back to line 1. Also, it doesn't seem to matter which display I choose in Flowcode, such as a 16x2. It even simulates like ...

I haven't been able to compile usable code to the F88, but I was able to with an F876A.
In the end I used hyperterminal to send an ASCII to the PIC and then displayed it on a 4x20 LCD. I've started playing around with VB2005 and in 5 minutes wrote a small program to send the contents of a user ...

I'm getting an odd compile failure error. With V2 of Flowcode I used the "Insert C Code" to add in assembly code for the Config settings of the PIC. I saved it as a Macro and would plug it in for each of my programs. Now when I use the same Macro, I get a failure to compile due to and error in the C ...

Is there an example I can look at to understand how to implement RS-232 communications between a PC and PIC in Fowcode?

I want to use a Modtronix board with an RS-232 connector to communicate with a PC. The PIC is a 16F876A. The board can be seen here:

Can I assume that since I purchased my Pro version in mid-September, I will recieve a free upgrade to V3? What do I need to do to make that happen?

How do the users who only just purchased get the free upgrade to V3?

Yes, the flasher works at the correct speed. I will play the the KeyPins and see what happens. Thanks again.

Ok, I have two things going on here. One is that I think the pinout for my keypad is wrong, or I'm wrong or both. Following what my datasheet says:
Column1=KeyPin3
Column2=KeyPin4
Column3=KeyPin4
RowA=KeyPin1
RowB=KeyPin2
RowC=KeyPin8
RowD=KeyPin7

and KeyPin6=NC

I have 10k Res inline on the Column ...

Sorry, i forgot to say that I am not using the E-Block keypad, but have wired it the same as the E-Block schematic shows, but rather than it going to DB9, it runs to Port B. And I do have it set to 8MHz under clock speed. The keys appear not to be stuck.
Also, I changed the pins that I am using to ...

I tried swapping around the ports. I set the LCD up on port A and the keypad on port B. The slow update of the LCD is still occuring as it was (the 1 second flashing of the characters.) It now flashes with a 10 and 4. ???

The LCD is on A0-A4 and A6
The keypad is on B0-B6.

Also I am using a ...

I am trying to use the Keypad component with a 16F88. I have connected the keypad to port A and an LCD to port B. To use port A, I configured for INTRC_IO so I could use A6 and A7. The component pin connections are set to:

Column1 = Bit0
Column2 = Bit1
Column3 = Bit2
RowA = Bit3
RowB = Bit4
RowC ...

That did it. Thanks.

I have the clock set to XT and the other settings like this:

asm __CONFIG _CONFIG1, _XT_OSC & _DEBUG_OFF & _LVP_OFF & _BODEN_OFF & _MCLR_ON & _PWRTE_ON & _WDT_OFF


and

asm __CONFIG _CONFIG2, _IESO_ON & _FCMEN_OFF

If I set _IESO_OFF (clock switching?), nothing comes up on the display.

Thanks. That helped. I've got it running close to real time, which is good enough.
Another problem: I changed the target PIC to a 16F88 with the same settings and 10MHz XT, but it runs very slow- about 1 second tic on the display every 5 minutes. Why would that be?

OK. I should have had the configuration for the 84A set to WDT off and PWRTE on . Had them switched. I loaded the Clock Tutorial (#22) and noticed that the count was not advancing on the display, so I played with the config and solved the flicker.

Should it count up close to "real" seconds? It is ...

I am playing around with an LCD display and a PIC16F84A. I can get "HELLO WORLD." to display but it flickers. This rate of flicker changes when I change the PIC clock speed in FlowCode. When I set it to 10000000 the flicker is least ( I am running with a 10MHz XT and all my connections seem to be ...

Is there an ETA for v3?

I just got it to work by inserting a C Code block at the beginning of the chart:

asm __CONFIG _XT_OSC

but it does not work with the #Defines component.

Sorry, I am a bit green with C. Most of my experience is in Visual Basic on a PC.

Is there anything wrong with doing it as pasted in C Code ...

I have tried the #defines component with this code: but it doesn't carry over to MicroPro and I don't see it in the asm file. What am I doing wrong?

I am using MicroPro to program my PICs from FlowCode and it is working good. Is there a way to set the configuration bits in FlowCode so I don't have to keep setting the fuses in MicroPro? By default it comes up with RC for the Oscillator which I then set to XT.

In the MPASM help file it has a ...
