Posted on May 17, 2011 at 12:17Quick questions for my friend on SPI and TImer1,
1) SPI:
When the ports are configured as SPI, on the STM it takes up 4 lines: MOSI, MISO, CLK, NSS.
(for no dynamic change of master/slave operations)
Q,when SPI is enable, can the NSS use as a general GPIO?
2)Timer1,
similarly, when some of the ports are configured as timer, say TIM1, which takes up 4 lines TIM CH1-4.
Q, if i only use one of them, can i use the other ports as GPIO?
Thanks
😉
