Logging Data Using PIC Microcontroller

02/10/2007 5:00 AM

I want to log data using a PIC Microcontroller to capture. PIC has limited memory. Would like to save the data on a memery stick. How do I do this? Addressing the USB M-Stick with a PIC ? Thanks pierre@proteafarm.co.za

Hello

I think this is a to hard task for a PIC. What you can do is to use a PIC with an UART and transmit the data to a PC and then save it to a memory stick.

You can take NAND FLASH (cheaply and greater capacity) and connect it to PIC the interface is so simple (protocol is not hard) and PIC will be not so charged (file system naturally you do not use). Data is taken away through UART if PIC is simple and cheap (115kb/s).
But if PIC is not cheap and not simple that you can use USB and it is possible for PIC. It will be slowly enough but if you have data bit rate some hundreds byte per second that normally.
If you want to see data from memory stick at PC it's necessary file system FAT or other .... For PIC it will be so sleepy but possible.
