If you can post your ADC question in the Flowcode V4 section of the Forum, I will reply to it early next week.

But in Flowcode V4 fourm the new post botton is not visible.That is why i am posting my problems in General PICmicro programming.

hi sean, I am using pic18f4523 having the 12-bit adc.There is a problem with the C code using in flow code the problem is the variable i had declare in the flow code is not called in c code macro.The other way what i thing is to same the adc value in controller innternal eeprom and read in the flow ...

Hi to all, I am using pic controller having the 12-bit adc .I just read the data from the Adc channel 0 in ReadasInt and display on the LCD when i vary from 0-5 v i got the value from 0-1023 instead of 0-4095. below i had set the settings in flow code. /**** Macro Substitutions **** 0 = Which ADC Ch...

hi sean,
i had sloved that problem thanks for the replay.

Have the hardware address pins (A0, A1, A2) on the 23017 been configured correctly? For initial tests these pins should be connected to 0v to match the device address (0) passed to the read and write macros in the example programs. Any changes to the device hardware address must be matched by the s...

Hi to all, I am making the project after writing a long program when i compile i found the erron in my code it shows:- D:\Pen Drive Data\Important Data\projects\BOD\Flow Code\BOD_Main19Nov.c(164): error: missing right paren D:\Pen Drive Data\Important Data\projects\BOD\Flow Code\BOD_Main19Nov.c(164)...

No i mean to say that if i am doing large progam and while doing the programming i need to disable the particler line of code like in C we use
/* */ to diable the code block and (//) to disable the line of code.

Hi to all,
How do i Disable the code block in the project.

For the Above post i am sending you the File which i had make.

Hi to all, I am getting the problem with splitting the float variable into two Bytes in the Flowcode simulation it is working but on the actual h/w the value of higher byte and lower byte are 0 and 0 respectively.I had check all the parameters like clock freq,MCU configuration.The other program are ...

Hello Benj,
Thanks, i had tested the prog and do the wiring according to you in is working now.

Hi to all,
I am new with flowcode i am make the program where their is 7 keys with pressing of particular key the program with switch to different screen.
I am not understand how to make it please help me to solve the problem.

Thanks benj,
I understand you .But the thing is i am create the small program where there is 20 screens in the C i can create the structure and store the screen status in the bit wise variable.but here i can only use the byte then there will be the memory issue.

Hi to all,

Is it possible to create the structure in flow code like in C.

I had already make it high.

Hi to all,
I am getting confusion with the keypad i am using 2x3 size keypad it is working in the program but i need to know that what will be the actual connection for the keypad.means to whom i need to give the pull for rows or columns.

Hello Hello A few quick questions. Does a simple program work. Eg flashing a LED with 1 second delays. Yes it works properly . Are you using a pull up resistor for the MCLR reset pin? yes . Are you using your own programming hardware or one of our boards? I am using my own h/w.But that is working fi...

Hi to all, i am get the problem to communication the MCP23017 with pic16f877A i had run the same program which had post previously i donot know where the problem is i am get .78v in all the pin even if give high the PortA the PortB values havn't changed. I put 4.7k pull up in data and Clock bus.
