mga master
meron na po bang naka expirience dito na yung microcontroller(any microcontroller) ay magsave ng data sa usb flash drive.
parang my LCD display ang microcontroller tapos kapag nagplag ng USB eh madiditek at pwede ka nang magsave ng data from eeprom. possible po kaya ito?

if usb flash drive to mcu ang setup, dapat meron embedded host capability ang microcontroller. Some PIC24 and PIC32 chips meron nito.

If ordinary microcontroller lang ang gustong gamitin, why not use a multimedia card instead of USB flash drive.

Medyo madugo nga ito kasi ako never pa rin nakagamit ng PIC na my usb host capabilty.

mas madali pa nga sa MMC or SD, SPI lang ang kailangan. kung gagamitan ng FAT, structure lang ang kailangan matutunan.

Use a MMC or SD cards (SPI protocol) and then use a USB card reader to read your data written on the MMC or SD card. UP Diliman students have used the z8 encore to write to MMC cards using FAT16 format in previous MADC contests. See
http://tech.groups.yahoo.com/group/microdesigncontest/
go to the "Files" section
then to the directory
"Open Design 2007-2008 Docs"
the entry
"Axel Monitor Phase 2 MADC Full Documentation.pdf "

You might need to join the egroup to access the files.

fyi :-)

mga master tnx.
mukhang mmc or sd nalang ang gagamitin ko.
meron po bang version sa pic?

Anong data ba ang isasave mo?

paranz · « **Reply #7 on:** April 14, 2009, 08:18:26 AM »

pwede na ang pic16f877a

but why not try making your own MMC card reader? you can use the popular PIC18F4550. PICmcu po yan na merong USB

time and date lang po, my input po na sensor ang microcontroller tapos po save nya po muna ang time and date sa internal memory, kapag my dumaan sa sensor, tapos po every week po save na sa mmc ang mga data.

meron nabibiling USB host controller IC sa farnell pwede ikabit sa MCU na walang USB capability.

maldihtah13 · « **Reply #10 on:** April 14, 2009, 10:36:47 PM »

pwede nman di na dumaan sa internal memory at direct na maglolog sa external memory. May ginawa na akong ganito pero kasya na sa external EEprom ang data. Tapos pwede mo makuha yung data using serial terminal. Hindi na kailangan ang sobrang laking memory.

rdpzycho · « **Reply #11 on:** April 14, 2009, 10:38:30 PM »

maliit lang pala. pwede nga 'yung maliliit na EEPROM. minsan nga lang irresistible 'yung PhP 20 MMC at SD sa CD-R King.

marami nyan sa sparkfun.com ang dami talaga ako gustong bilhin dun....haaayyyy...ubos na budget ko eh

agg_asd · « **Reply #15 on:** May 11, 2009, 04:16:08 PM »

patulong naman po baka my sample project kayo dyan......
