Hello Joris On your XP machine did you try restarting. Sounds like an uninstaller failed and is now causing the windows installer to be unavailable. Fingers crossed if you restart your machine and then straight away run the setup it may install correctly. Vista should also run TINA. At the moment it...

Hello Bert

You can create a C variable and then call it in assembler by using an underscore in front of the variable name. Would that work?

char varname

asm{
movlw _varname
// rest of the asm code
}

Hello PWM is a hardware function and uses CCP pins. These should be marked on the chip diagram in Flowcode. CCP1 is PWM channel 1 and CCP2 is PWM channel 2. If you wish to output PWM to any old pin you will have to do it by toggling the state of the pin in software. Using a timer interrupt could com...

Hi Wayne

I think Steve is postponing announcing the details until we are sure what is going to be included. Theres going to be a lot though.

Hello

You probably have to wire up your LCD like this.

PortB.0-->Data4
PortB.1-->Data5
PortB.2-->Data6
PortB.3-->Data7
PortB.4-->RS
PortB.5-->Enable

RW pin tied to Ground.

Hope this helps.

Great thanks Achillis,

Sounds like a great project and would be interested to know how you get on.

Hello I am using a nested for loop because 1 of the delays from your previous program delayed for approx 1/20th of a second. Now I am calling that same delay 10 times to allow for a delay of 1/2 a second. I cannot simply increase the size of the original delay because the Unsigned INT variable size ...

Hello In answer to your questions 1) 65000 is the number used to assign how many program cycles the chip should wait before continuing to the next instruction. 2) That particular value is used because it roughly generates enough of a delay when running at 20MHz to allow for 1/20th of a second delay....

Hi Damian Sounds like a great project, might have to give that one a go myself. Where there any specific delays involved or is it quite easy to guess the delays needed between the LED outputs? Glad its all up and running for you now and that your finally seeing the good side to Flowcode and our ECIO...

Hello Fred

Shame you had to resort to a reinstall but glad its all working for you now. Let me know if you have any problems.

Hello Flowcode variables are given the prefix FCV_ in C code. It is this C code that is compiled to give you your working program. Flowcode V3 does not currently have direct access to registers onboard the chip without using C code. You would insert writes from your variables into the timer register...

Hello Achillis To save data to Excel format there is two options. 1) Send data via the USB to a software application eg VB which will append the incoming data to a file in an excel format eg comma seperated variables. 2) Send data directly to a SD/MMC card which will append the incoming data to a fi...

Yes you can insert the assembler code directly in a C code Flowcode icon so you will be able to edit and comment the code as well as add other Flowcode features such as displays etc.

Hello Yes the SD/MMC card would just allow you to locally store data in a fashion compatible with excel etc. Eg timesheets could be logged and then at the end of each month the card is removed from the system and inserted into a PC where the data is copied across for working out wages etc. Obviously...

Hi Wolfgang For your program timer_set_00_dec = 901 timer_00_set_wert = ToString$(timer_set_00) a timer_set_00_dec = timer_set_00_dec - 1 wait timer_00_set_wert = ToString$(timer_set_00_dec) go to a Would become timer_set_00_dec = 901 timer_00_set_wert = ToString$(timer_set_00) timer_00_set_wert = t...

Hello Dont you just love assembler code, Im so happy it finally dying a death. There is now a stepper motor component available for Flowcode which should make your life a lot easier. Simply extract the contents of the attached folder into your Flowcode V3/Components directory and then run the Instal...

Hi Wolfgang

Yes thats normal. What you need to do is print one or two characters of white space after your number to make sure the previous number gets erased.

Eg instead of printing "100" and then "5" which will lead to "500", print this instead "100 " and "5 " which will lead to "5 ".

Hello Yes the system you are proposing should be acheivable using Flowcode and a RFID E-Block. Each member of staff could have their own RFID tag and as you say switches could be used to assign new tags etc. Time can be based on an interrupt on the chip and will be highly accurate (eg prob loose or ...

Hi Damian

Ah ok hopefully that will sort out your problem then.

I will try and make it clearer what you have to do in the documentation.

Hi Damian If your getting the advanced configuration screen then your have not selected the ECIO target instead you have selected a standard 18F target. The ECIO devices should have no configuration settings at all (should be greyed out) to protect the bootloader and as you say be beginner friendly....

Hi Chevvy

Here is the current version hot off the generator tool.

Hello Here are a few other things I can think of. Do you have the latest version of Flowcode installed V3.4.7? Are you running any heavy anti virus or firewall eg Norton or Mcaffee? Another piece of advice I have found is to do the following. http://windowsitpro.com/article/articleid/72659/jsi-tip-1...

Hello To break a variable into powers of ten you will have to do something similar to the following. INT_Var = 10500 thousands = INT_Var MOD 1000 //should equal 10 INT_Var = INT_Var - (thousands * 1000) hundreds = INT_Var MOD 100 //Should equal 5 INT_Var = INT_Var - (hundreds * 100) tens = INT_Var M...

Hello Fred

What version of Windows are you running? Also do you have admin rights?

If your using Vista then maybe try right clicking the .bat file and selecting run as administrator.

Hi, The PICstart programmer requires MPLAB, I think that it is possible to setup Flowcode to use the PICstart so it may be possible to configure your compiler to also use this programmer. There should be a topic on this forum regarding integrating PICstart into Flowcode which should help you get sta...
