Hi! As said in the PRU topic, I'm working on a 32 channels servo controller using PRUs. The aim of this controller will be to drive servos synchronously, ie they should start/stop at the same time. Like these dedicated boards do:
http://www.lynxmotion.com/p-1032-ssc-32u-usb-servo-controller.aspx http://www.dfrobot.com/wiki/index.php/Veyron_Servo_Driver_(24-Channel)_(SKU:DRI0029) (I own the second one). The question is: which pins should I use for the servos, and which ones should I keep for other purposes (future features)? For example, I think I should keep: - 1x I²C bus - 1x SPI bus - 1x UART - a few PRU direct access GPIOs (for fast rd/wr, like pulse measurement...) - pins which can be used for timers/counters inputs As far as I understand, UART0 can be used directly from PRUs. But UART0 is the one wired to the FTDI-compatible header; is it a good idea to use it for other purposes than debug the board? What about the I²C 2 bus? It seems to be allocated; is it used by linux for some board chips access? What other pins have usefull usage I should be aware of? Thanks for feedback and suggestions.
