I looked at that link before, wasnt much use im afraid. What im trying to do is convert my int value to a float, then to a string to display on screen to 1 decimal place. so in the calculations i do, FLOAT = SAMPLE Then in string manipulation, STRING = FloatToString$(FLOAT) All i get on the screen i...

Hi, I would like to be able to display my temperatures like 32.1C, 32.4C as apposed to just 32C, 33C. I am using ADC and realtime calculations, i end up with my real temperature value to the closest whole number. Im doing this: (TEMPERATURE = SAMPLE / 3), This gives me my single number value. How do...

whats new for V5??

Hi Martin,

Thank you for the link, that works spot on for me now.

Hi, i have 2 strings that i would like to compare, The first string called "in_string" is the data being received, in that string is 4 characters, e.g "STID" The second string is called "STRING" and is in a string manipulation box, STRING = "STID" OK, so i send my 4 characters STID and it stores the...

I have tried modifying the code i was sent to go with the custom.c file.

I managed to get the code to compile and downloaded to the pic, the line was showing up but it was 8 pixels thick and still had gaps and random pixels around it.

hi

I tried that little change and its still the same as before.

whats the rest of that code about where he writes to the ram etc

Ben, Iv sent you a PM

hi,

It doesnt matter what i do to it, it doesnt display correctly

plotting a pixel only works on the top line, after that the pixel location is wrong,

when printing a number ot a string, i just get a line,

The box was the closest i had to doing something it should

OK, I have gone through pages 41-42, and checked it against the code. void MX_GotoXY(char x, char y) { char page, columnl, columnh; page = (y / 8) | 0xB0; ****correct**** columnh = (x >> 4) | 0x10; ****correct**** columnl = x & 0x0F; ****In the datasheet this says it should be 0x00, when i put that ...

Ok no problem,

If it helps the st7565 is a COG controller so the lcd will have a little chip under it surrounded in silicone

Is there anywhere else in the code i can look to solve this problem?

hi ben

When making this change instead of the box i get 3 lines at the top and loads of scattered pixels

ok, more problems, when drawing a box to fill the screen my coordinates are 0,0,127,63 (this works as it should) when putting a 1 pixel border around the box i use 1,1,125,61 (the 1,1 is correct, but the 125,61 should be 126,62) so its 1 pixel out when putting a 2 pixel border around the box i use 2...

Iv just been going through the forum looking for some inspiration when i came across this

http://www.matrixmultimedia.com/mmforum ... =29&t=8035

this is pretty much whats happening to me, was this ever figured out??

Hi, i have just noticed that my chipset it a "ST7565R-G"

will this cause a problem or should it work ok, i cant find a datasheet with the G extension

Dont suppose you know what lcd you used when testing this code??

A quick update, I have now got the LCD to initialise, i am using the speed test file. There was a line missing to switch the lcd on, I can see the X on the LCD corner to corner, but the lines look like \\\\\ they are not connected and are not in the right place, but i can see it flashing on and off ...

Hi Benj,

Im using a 19.6608Mhz crystal, i have also verified that the code is running with a blinking led.

I have LVP disabled and have checked I/O using leds on my lines, all seems in order.

I will try the nop instructions, is there anything else here that might come into play?

Hi, im playing with the ST7565 custom file, Problem is i cant seem to get it to do anything. Just a blank screen, do you by any chance have the schematic you used when testing this file?? I have tried the c86 pin high and low and also the P/S pin high and low, but nothing. I have set the custom file...

just been reading that this can be done using adc, using the internal capacitor.

Anyone got any idea how to make this work in flowcode??

V3 doesnt have the 726, but if i know i can make it work on V4 then i would probably buy v4 to do the job on,

I have seen other people use chips like 16f610 and 16f887, but i dont understand how they do it.

Hi Guys

I was just looking for a replacement to my QT320 IC, i came across the PIC16F726, this pic has a capacitive sense module built in.

Has anyone ever used flowcode to use this feature??

Can flowcode even be used to make this feature work?? I need to 4 keys to replace what i have already.

dont worry i figured it out, in the custom.c file im using it says the following: /*Macro_LCD_Print_Number_Start*/ char string_length; if (Number < -10000 ) string_length = 6; else if(Number > 10000 || Number < -1000) string_length = 5; else if(Number > 1000 || Number < -100) string_length = 4; else...

Hi Benj, The image might be a bit more than i can do at the moment. Think ill just draw the image using line command. I am having another tiny problem, when creating variables to make a number increase or decrease, the number displays ok, but when it gets to 10 it just displays a 1 and for 100 it di...

Using a KS0108 LCD and also a PIC 18f4685

Can flowcode be used to convert a Bmp or Jpg to show on the LCD?

If it can does anyone know how??

I can draw the image using loads of draw line commands but this would become a major headache after a while

ok narrowed this down a bit more, learning more and more every day. this is what i think these mean... adcon0 = 0x3C; (set all ADC to unassigned) adcon1 = 0x0F; (set all pins to Digital I/O cmcon = 0x07; ( turn off comparator) just to see which was causing the problem i deleted them one by one from ...
