sorry guys I guess I need some more direction with this one. OK I'm looking for a particular sequence of characters in a RS232 input. As per my previous post the ssequence is Stopped. So i looked at how to test for the sequence and thought a number of Yes/ No decisions would be the go. The problem i...

Hi I want to perform a component macro in Ver 4 when a certain string in this case "Stopped" is received on the RX receive pin of an 18F458 PIC. EG I am sending commands to a vmusic2 module. When the MP3 file(s) in a directory finish playing the vmusic2 responds with "stopped". When this string is r...

OK I had the set up as recommended, ie masking the correct ports. What I found worked was use a variable. i called one variable for setting masked outputs high and another variable for setting masked outputs low. I made variable B_output_high = 255 and B_output+low = 0 and used the mask to set the c...

Hi I am simulating a 16F628a and i have leds connected to B0, B3, B4, B5. I wanted to flash these ports on and off about 4 times and then leave B5 on. I tried this using port masking checking the ports listed above and also by trying by just selecting all ports without masking. the only port that fl...

Sorry to bother you again but can you steer me in the direction of code for say a 4 x 4 keypad matrix. I have the basic idea 4 x columns x 4 x rows. Each column is made high in turn by setting the equal port to a 1 and each row is read in turn (for each cloumn and checked for a high. I'm guessing th...

I am looking at controlling a number of leds and the only way I can see to do this is by using a second microcontroller. I'm looking at about 40 leds which will light in various combinations. The combination will depend on a keypad selection. This keypad selection will send serial code from the 1st ...

Hi How would i go about designing a macro to simulate a 4 x 4 keypad. I'm guessing that you make the equivalet of 1 column high and then read each row and repeat for each column, but where do you go from there? Any suggestions or Links that I could learn more from would be appreciated. regards Ian B

Hi I'm writing a programme in flowcode that uses a keypad to determine what particular folder of music plays. The music is stored in various folders on a usb stick and the usb stick is plugged into a vmuisc2 module, whic in turn is connected to the pic microcontroller Example If keypad 1 is pressed ...

I've just purchased Flowcode 3. When is version 4 being released please.

Hi
how to i tell a port that it is being used for RS232 comms rather than a standard digital port. although this is a generic question the chip I am using at present is the 16F627.

Thanks

Hi
When i send a CR (13) I only see an asterisk on the RS232 component. If i send text such as Hello I see that OK.

I know CR is not a printable character so I'd suspect the asterisk might be flowcodes interpretation of the sent CR.

Would this be correct?

Cheers

Hi
I'm looking at a project that would require more than the 12 keys in a 4 x 3 keypad as per components on flowcode.

At present I am only using the evaluation software before committing my funds.

Is it possible to use a larger keypad , matrix and how would this be done.


Thanks

Ian

I'm just evaluating flowcode as a method of programing for a small PIC project for use in disability sector. I'm trying to work out how to send specific ASCII chahracters from the TX port of the pic. Example in simplist form Keypad button 1 is pressed and characters cd\ followed by ,cd B1 followed b...
