Hello, As I was going through interrupts, I noticed that the settings for TMR0 Overflow interrupts are not showing any difference when going through prescaler values. http://recycle-your-animals.net/misc/fc4.png Is this a bug, as I remember this working correct in FC v3 for the AVR. Kind regards, Nils

Hello,

Would you have a sample Flowcode v4 AVR program for this E-Block comparable to the one you have for the PIC micro?
This would be needed to jump start a project on IR control or a remote fan.
Thank you.

Kind regards,
Nils

Hello,

I am sorry to bother you again, but as I need to work with bluetooth communications in a project, I would like to resolve my problem.

Thanks,
Nils

Hello there, I am trying to revive a EB024 Bluetooth board, which seems to elude any attempts using it. We worked with the bluetooth board and an AVR programmer for some days and returned one morning back to the lab finding it not working at all. The use case was pretty simple: - setting it up as di...

hi I scripted a nice Perl script which takes care of all the settings you usually would have had to do by yourself. and there is also a small description of what is going on in this file with all the Macro* definitions. take a look in my sig and go to the Custom_Code. c help needed link. there you'l...

ok, here it comes. after I took a look in some FAQ' about AVR gcc I found the answer I was looking for. I have no idea why it doesn't work the other way round. // this include is needed, to get access to the program functions // and special keywords #include <avr/pgmspace.h> // table for sine wave o...

yes, I already came across this pitfall when I began using C code ;) I am not simulating now and working with the actual hardware bits: AVR programmer and LCD E-Block. I do have really now clue what is going on with arrays implemented in the Custom Component, so I tried to do the same thing without ...

hi again I just wrote a very small C program to see what was going on, because I couldn't get it running with the microcontroller. first I have to achknowledge, that I should have set the variables to both unsigned char to avoid any confusion with signed values. changing this, the output on my compu...

Hello I am using the AVR programmer with an Atmega32 and the LCD E-Block. Then I use the Custom Component to implement a lookup table called aSineWave inside the GetDefine dummies. In the Custom Component function TestWave I try to access this array, but I do not get anywhere. I tried to print it ou...

hello steve

thank you for the insight. so it is possible, not in the way I thought, but this is fine with me.

cheers,

Hello My question is about the site licence you offer for Flowcode. As far as I understand, you are then allowed to install it on as many computers you want at e.g. in the University, if this is the licence's owner. But is it ok then to give the students, who attend a lab in microcontroller programm...

Hi there

as I already suggested a vector based output of the flowcharts for Flowcode, I came up with a solution on my own which I want to share with you.
So here my small howto to get a scalable flowchart for everyone.

again have fun with it, comments are welcome.

Hi I like the idea of exporting the flowcharts as images, but it would be really really nice if there were a vector based output for these i.e. SVG, PNG, PDF, EPS or PS. Why? Because then scaling wouldn't be tied to loss of quality but only in readability of the small font when scaling down. The nex...

I thought about something like manufacture default setting.
It just is only confusing for the first time you notice that a second is not a second and wonder why...

anyway, thanks for clearing that up

cheers,

Hi even if I hijack this thread a bit, but is there a description of how to set up the bluetooth E-block module for an AVR device ? and if not, is there a short description of which port it has to be connected to. my best guess is Port D at an Atmega32 because of the USART connection. the purpose is...

Hi Peter Flowcode should work as soon as you registered the Components, either by - batch file - or by simply running the installer inside Wine. the latter worked for me fine in Wine 0.9.55 and with Flowcode AVR. the only problem left is getting the USB programmer to work and that seems impossible t...

Hi I noticed, that the Atmel Atmega32 that is shipped with the AVR programmer block is not set to the external crystal, but instead to the internal RC clock of 8 MHz. I know this has been resolved by editing the fuse bits, but right now there is no easy way to access these bits inside of Flowcode, o...

Hi there

new updated version of the documentation:
- changed flowchart
- added a short description how to invoke the script in Win/Lin/Uni/Mac environments

have fun with it

hi I enjoy programming with flowcode, but I really really miss more shortcuts/hotkeys I know that clicking buttons is quite easy and intuitive, but sometimes I want to upload the code to the microcontroller with a nice shortcut, like you did for the whole "Run"-menu. or make it as opt-in in a prefer...

version 1.2 changed recognition of functions, so that ugly things like this one void Test(char Foo, short Bar){ugly code; do not try to do so;} will result in void Test(char Foo, short Bar){ /*Macro_Test_Start*/ ugly code; do not try to do so; /*Macro_Test_End*/ } and now time stamps of the backups ...

Hi I played also around with PWM but needed mopre control over it, so I chose to implement it by myself in the Custom Component as functions that I can call then by the Component Macro inside Flowcode. the problem is, that as soon as you use C code in Flowcode it does not simulate right anymore, but...

version 1.1b_2 hi there this evening I tweaked a bit the code for supporting different styles of braces, as I know that you folks of MM do it another way as I do, and maybe others out there too. now following things are possible: void something1(){ some code; more code; } void something2() { some co...

so if anyone is interested in what my script is doing (in a brief explanation + flowchart), I wrote up a little LaTeX document to introduce my script and the "Macro" definitions I am altering/generating with it. hope it helps people that were a bit helpless like me seeing the Custom_Code.c file for ...

dupe, double post

I thought you would ;-) it is not completely bug proven, but it works for me. unfortunately it does not contain compatibility to your style of coding i.e. void something() { some code; more code; } in contrast to mine that is void something(){ some code; more code; } but maybe you have the excellent...
