...but it hasn't arrived at my email yet, what do I do?

I bought it 4 days ago BTW, and already sent an email to r.barry @ freertos.org

Sorry to here you have had a problem receiving your documents. I have been out of communication for a few days so, while a colleague has graciously been sending out the documents on my behalf, I will not have seen your email request.

Normally missing emails turn out to have been filtered or blocked somewhere along the line, so I guess this is what will have happened in this case. In any case, I will ensure it gets sorted as soon as possible.

Regards.

If there is an issue with Hotmail recieveing the file, maybe you could send it to this other address: mgurrola@gdl.cinvestav.mx

Thanks

PS. If you need some kind of receipt, tell me what should I send you

Dear Richard,
I would like to start learning freeRTOS. I will be using PIC18F452 with Microchip's C18.
Which edition of your book "Using the FreeRTOS Real Time Kernel - a Practical Guide" would you recommend?
Thank you.
