… standard modm::can api

…king, which should be fine because it is controlled via interrupt

… as well; fixed some things in example

…evice is now used internally for aquiring / releasing the bus whenever accessed

…he spi clock frequency when master is acquired

…ationHandler in example; changes canbdaudrate to 500kbps

…to the mcp2515 driver, because it should not be in user code

…ize and no SpiDevice bus mutex because SpiDevice only allows to be inherited from (protected api) ... this is a little better, because now you can call the driver from wherever (static) but it internally allows/needs instantiation and update polls for controllign the context the driver runs in

…properly which lead to infinite interrupts; added some more buffers for the different more or less concurrent read/write variables; added stuff to example;

…vel intact

…dify()

…t (aka NOT attempting to send it) if the mcp is not readyToSend() instead of waiting for it to be ready, which defeats the point of buffering packets indefiniteley

…code; minor style changes to mcp2515 driver impl

…d unused project xml things; cleaned up unused headers; changed mcp2515 driver class attributes to not have _ underscore postfix

…rescaler
