SD Card data loger over SPI

[pablo]

Hi Everybody
Just registered here, but been visitor for a long time!!!
I am working on project with WC8 + several 1 wire temp sensors18b20
I would like to log and store data on SD card with SPI
Did anybody worked with WC8 -SPI???
Please let me here what You think about it???
Regards

This sounds like a good job for an Arduino.

You can through PLC code to write data bytes into external SD storage on the SPI or I2C bus.  There are a lot of I2C and SPI EEPROM chip modules out there. Anything that Arduino can work, it will also work on WC8 and WC32.
 
On the other hand, WC32 can directly plug an USB thumb drive on its USB bus, then simply change configuration to enable log, any IO change will be automatically logged into flash drive. You can later put that flash drive on computer to view the log data.

Apologies!  I didn't see the forum.  Yes, do it on the WC8 or WC32!

@dementeddigital, It is okay.  Most things other platform can do, they can also be done through PLC code at higher level.  WebControl through its PLC engine removed most lower level timing and protocol details, so that user can write PLC code to handle them easier.  SPI and I2C logic is fully supported in PLC, users don't have to worry about timing on WC8 or WC32. But unless it is popular item, like I2C real time clock fully supported by default in firmware, other chip modules users still have to follow the protocol steps. However, if you have specific needs, we can support them here in discussions.
