Simplest way to write to USB stick or TF/SD card with PBP?

[CuriousOne]

Well there are several solutions capable of doing this. FTDI has this: https://www.ftdichip.com/old2020/Products/ICs/VNC2.htm
I've bought ones made by Parallax back in 2011, and they were around $45 ea now prices are about 8 times lower...

I had a PBP project to write to a SD card and it worked. That was many years ago and I don't remember the details of it, but it works. Attached is the sample code that I downloaded from the internet. Just change the file extension to PBP or copy paste the code into your program.

For data logging type applications I've had great success with the OpenLOG. Just send it ASCII data over a UART line and it will write it to a .txt file on an microSD card.

Thanks!
Any sample PBP code?
for OpenLOG ?

[HenrikOlsson]

Again, for simple datalogging type applications there's really no need for any sample code. Just send it ASCII data over a UART line and it will write it to a .txt file on a microSD card. It CAN do more than that if needed, I suggest you read the documentation. Sparkfun (who I believe created (and should have all the credit) the OpenLOG) have a tutorial but I'm sure you've found that already...

[CuriousOne]

Their tutorial is quite weird.


I do need additional hardware or can hook it to say PIC16F886 directly?
Also, about Baudrate and other init options, it is not clear I need to do it each time on power up or just once?

[HenrikOlsson]

No extra hardware needed.
The easiest way is to put a config.txt, containing your desired options, on the SD card. See the Configuration File section of the tutorial.
