ESP8266 Community Forum

- Thu Aug 11, 2016 11:36 am #52710 I have trying to program ESP8266-1 in lua for a few days, so it could be problem that I'm doing something wrong. I have written simple program to test files.
Idea was to get as much data as I could from sensor. It mean that I was going to write data to file, and when filesystem would be full delete oldest file.

after several runs (about 340) my module hangs, reset with reset code 2 !!! what was impossible. Reset pin pulled.

curr file 348 file to del 51
Waiting answer from ESP - Timeout reached. Command aborted.

module doesn't respond to Esplorer even when I try to change lua file

but after format module work OK.

Question is if there is a bug or am I doing sth wrong

my module ESP8266-1,

there is my code

    singleLua=0
    print ("init")
    FileCurrNumber=0
    FileDelNumber=1
end

dane=FileCurrNumber
    for num=0, 100, 1   --init data file
    do
        dane=dane.." aazzaaax"
    end

if singleLua~=0 then
    singleLua=singleLua+1
    if singleLua>3 then
        singleLua=0
    end
    print(singleLua.." meas ")
    return
end

singleLua=1

maxFileNr=500        --OK
FileName='awyn'     --OK
FileExt='.dat'     --OK

    r,u,t=file.fsinfo() print("Total : "..t.." bytes\r\nUsed  : "..u.." bytes\r\nRemain: "..r.." bytes\r\n")
    if(r<20000) then --less than 20k free
    maxFileNr=1    --delete one file
    end
     r=nil u=nil t=nil

print("curr file "..FileCurrNumber.." file to del "..FileDelNumber)

FileCurrNumber=FileCurrNumber+1
fileCntr=FileCurrNumber+1-FileDelNumber

fileCurrName=tostring(FileName..FileCurrNumber..FileExt)

file.open(fileCurrName ,"w+")
file.write(dane)
--wyn=file.seek()
--print('dlugosc = '..wyn)
file.flush()
file.close()

print (fileCurrName)
print (fileCntr)

if fileCntr>maxFileNr then
    fileDelName=tostring(FileName..FileDelNumber..FileExt)
    file.remove(fileDelName)
    FileDelNumber=FileDelNumber+1
end
singleLua=0

Wow, you're really dumping a lot of stuff onto the flash But that shouldn't render the file system unusable.
In any case, it might be that the loop prevents the watchdog timer from being serviced. If it's running for more than 5 seconds, then the ESP will be reset by WDT. Please try to add tmr.wdclr() and report the results here.

- Fri Aug 12, 2016 12:28 pm #52793 with tmr.wdclr() there was record with 385 file runs.

Total : 397082 bytes
Used : 377253 bytes
Remain: 19829 bytes

curr file 385 file to del 87

while line 45 mean:

[code

47 --print('dlugosc = '..wyn)

49 file.close()[/code]

So clear of wdt could a little help but not solve problem.

I have tested work on 5 different modules ESP8266-01 from different shops, but I have only current build, and results are the same.
Question is if you could test program with your modules - code from post #1 is complete file - I wasn't able to attach lua file. I have run file with timer every 1 second
