Hi Nico This was the part that confused me the most. I did compile the terminal but dont know how to use your HAL like framework. Would you mind giving some pointers please. I have ordered my STM board already and I want to really partake in testing your work. > Nico > >> On 11/22/2014 12:49 PM, el cringo wrote: >>> Hi, >>> i just added pdfs for the current hw version.
