Re: [Machinekit] using hal_spi module

[schoone...@gmail.com]

See https://github.com/ArcEye/machinekit/tree/hal_spi_base I have used the simplest strategy.  As only the _PERI_BASE seems to be different, I have changed the #define to an unsigned int variable. This is then set to either 0x20000000 or 0x3F000000 depending upon version detected. Just added code for number_of_cores() and included cpu_info.c to get the others. It builds but needs testing If you get problems, add some DBG prints to see what revision and number of cores is being returned regards On 29/09/18 17:56, mngr wrote: https://github.com/mngr0/machinekit Il giorno sabato 29 settembre 2018 18:50:47 UTC+2, Schooner ha scritto: Can you link to a github repo with this in?  I will look tomorrow. You have probably declared something as extern or otherwise done enough to satisfy the compiler, but not actually linked it or similar. Each driver probably needs to have all the routines and info within it.

Hi, Gemi has wrote this driver for a particular board      https://github.com/kinsamanka/PICnc-V2/wiki . I can't believe that it is very useful for someone else. IMHO the nomenclature isn't overly happy. A little bit to general. ;) BR I need a way to write commanded velocity on the spi, my bigger problem wiill be on the spi-slave, and this seems to me a pretty easy protocol to implement   -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
