Thanks... it was nothing... now when i get a LCD working on this ill be happy heh... havent touched it ever since tho
I'm using the Cosmic compiler, but not sure how to download the code into the training kit yet. Anyway, these are nice stuff to play with.
I'll be ordering a 2nd training kit with some cheapo Microchip temperature sensors, and if I have the time, I'll be making a cheap radio-clock!
However the DIP versions are not out yet - apparently these STM8S are very new. I hope Farnell or RS will stock up on those stuff.

}I also love to buy one. But the shipping cost is 5 times more that the product.
no need to apologize...
