Benj,

Any luck replicating this fualt on your set up

Hi Benj

Done a full format and still get the same result

Hi, I have not tried a full format, What happens even when using your .wav test file is that it will play approx. 2 seconds absolutly fine then it hangs up with a hissing sound followed shortly with a sound like a stuck CD and stays like that until i reset it and it starts again then hangs up again ...

hI

Please find attached program

regards

Hi,

I am now a step closer, the card was not formatted right. But the only problem now is i only get about 2 seconds of sound then it locks up and all i get is a hiss or a looped noise like a dirty cd . any ideas ?

Thanks for your help so far

Its a 20 Mhz crystal (i also tried a 19.6608) on a EB006 development board and used the setting from emanuel program and also tried to adjust them but nothing seem to change ???

Hi,

OK i have load a program to the 4455 ic that just prints "HI" in one second intervals to the LCD , but when loaded to the hardware it takes 20 seconds to repeat the message. i think this is the problem but how do i solve it to get the timing correct

Hi,

Still having problems now it will not ID the chip when compiling or clicking on auto detect. Place a 16f877 in the ic socket and it see's it no problem, changed it with a new 18f4455 and i get " Could not ID onboard chip "

Any ideas

Wayne

Hi,

its the example program you sent me, please check chip config on my program

using EB006 Board with a 19.6608 Mhz
EB037 with jumpers on "A" and 5V and 16M MMC Card

Thanks

Wayne

I was going to use a PIC16F877/A with it's internal clock on a EB006 development board using Flowcode 4, there a limit to the size of memory card or class

Hi, You show a example of playing a wav file from a sd card e-block, but can you give me some more info 1. the chip config in example is shaded out, what is the clock speed (internal,rc,xtal) 2. the sound output is on what pin (pwm) 3. what input is card reader on 4. what kind of circuit did you use...

Good morning Benj,

What i was trying to say is on the scope from the rs232 on the pc i get the following
Null=logic 1
0xFF=logic 0
From flowcode i get
Null=logic 0
0xFF=logic 1
Which would say RS232 from flowcode is not inverted

Any idea's

Regards

Wayne

Just two more question how to set up the stopbit and parity, also when i look at the data on my scope it is inverted to what i got from the pc?

Rgds

Wayne

Benj,

Am i right in saying i have to open a RS232 send macro for each of the above,i.e null then 0xff and so on

Rgds

Wayne

Hi I have just captured the following RS232 data string from a pc to a message board <NUL><FF><FF><NUL><VT><SOH><FF><SOH>01<STX><EF><BO><EF<A4>TEXT<FF><FF><NUL> This was sent @ 2400buad, databits 8, stopbits 1and parity none How would i achieve this using the RS232 component in flowcode 4 Regards Wa...

is there a relaese date yet ?

Rgds

Wayne

what can we look forward to in flowcode 4

Rgds

Wayne

Post your program and i will have a look

Hi steve,

Sorry for pestering you, But how do i break down the 209 (tag) into powers of ten. I will get my head round this !

Rgds

Wayne

Benj,

The answer to my calculation is larger than 1 byte, so what type of varible do i use. INT is ok for the first calculation, but when i get to tag2*256*256 it comes back as zero

Rgds

Wayne

Is there any information on this site on how to creat a macro, so i can have a go at doing this calculation.

thanks

wayne
