Save file on the sd card from html client


hi,

trying days store config file web page sd card.

the rest command use "/arduino/saveconfig/data"
where data json string.

on arduino site collect data with  code myfile on sd card
myfile filesystem.open("/mnt/sd/arduino/www/project/myfile.cfg", file_write);


while(client.available()>0) {
  c=client.read();
  myfile.print(c);

this works ok till configuration size bigger 500 bytes.
if size bigger 500 bytes  timeout.

are there possibilities write sd card in other way?

regards

sahin

for big size file please bypass fileio @ atmega32u4 , let ar9331  take care only.

code: [select]
nano /mnt/sda1/download.py

code: [select]
#!/usr/bin/python
import urllib2
zipfile = urllib2.urlopen("http://download.thinkbroadband.com/10mb.zip")
output = open('/mnt/sda1/10mb.zip','wb')
output.write(zipfile.read())
output.close()


code: [select]
chmod 755 /mnt/sda1/download.py

profile code:

code: [select]
time /mnt/sda1/download.py
real    0m 7.64s
user    0m 2.55s
sys     0m 1.49s


it take 7.64s download 10 mb file , save @ microsd.

by use sys.argv  and process   ar9331  could control atmega32u4.

code: [select]
void insertdb() {
 process p;            
 p.begin("/mnt/sda1/download.py");      
 p.addparameter("http://download.thinkbroadband.com/10mb.zip");
 p.addparameter("/mnt/sda1/10mb.zip");
 p.run();
