serout to vfd

Gabrielroto

I have a vfd (vacuum fluorescent display) that will accept serial strings from the BS2P. Like this SEROUT disp,16429,[noparse][[/noparse]"Hello World"]. I would like to serout a the contents of a variable but I'm not sure how. For instance: If the debug screen says adcres = 2500 then I want the 2500 to show on my vfd screen. Here's what I have so far.
HIGH cs

MAINIO

main:
DO

LOW cs
SHIFTIN dout, clk, MSBPRE, [noparse][[/noparse]adcRes\13] ' shiftin bits from 12 bit ADC
HIGH cs
adcres= adcres-6247*10
DEBUG adcRes,CR
SEROUT disp,16429,[noparse][[/noparse]adcRes] ' Trouble Here!!!!!!!!!!
PAUSE 100
GOTO main

LOOP
END

I want

Gabrielroto -

See if this gives you what you want:

SEROUT disp,16429, [noparse][[/noparse]DEC 4 adcRes]

Check the syntax of the formatters (DEC is just one of many) either in the PBASIC Help File (within the IDE), or in the PBASIC Reference manual. Unfortunately I don't have either resource handy - sorry.

Is it possible for me to format the 2500 as 25.00 without writing code for each individual digit?

Gabriel,

As a note you would not be getting an output adcres = 2500 with the code you posted. The DEBUG screen would also have garbage using that format because you’re sending a raw binary value to it, rather than an ASCII string. The DEC formatter will work on both the DEBUG and SEROUT commands.

yep, that's exactly what was happening before. I took bruce's advice and did some research on serout/DEC. I have some code that does the whole 00.00 thing, but it's a little long. If I can, I'd like to learn a shorter way to go about doing this. I have a load cell and when I squeeze it I want the numbers to go up and down in this stop watch (00.00) kind of format. I figured out that 88 (8.8*10) is equal to one pound of pressure so I'm still working on that math too. Anyhow thanks for all you guy's help.

This is the best way I could figure out how to do it for a temperature display. I only showed to one decimal place.
This was for an LCD so I added a leading space when the temp is under 100 degrees to keep things lined up.

IF ( Temp > 999) THEN
  SEROUT TxPin, Baud9600, [noparse][[/noparse]DEC Temp DIG 3, DEC Temp DIG 2, DEC Temp DIG 1, ".", DEC1 Temp]
ELSE
  SEROUT TxPin, Baud9600, [noparse][[/noparse]" ", DEC Temp DIG 2, DEC Temp DIG 1, ".", DEC1 Temp]
ENDIF
