Hello to all,
I’m prototyping a new cape board for BeagleBone Black.
I have designed most of the circuit and now it’s time to connect all the thing to the beaglebone.
I have a problem: I can not figure out whitch PINs can I use.
I read the BeagleBone Black System Reference Manual and the AM335x Sitara Processors datasheet, but I can’t find where all the pin’ s feature are explained.
I some different kind of connection:
- 1 I2C bus (it’s OK, ill use P9 17 and 18 PINs)
- 1 UART with CTS and RTS
- 2 IRQ from push buttons
- 4 analog channel (it’s OK, ill use AINs PIN on P9)
- 2 SPI bus
- 3 PWM channel (standard PWM modulation, fixed frequency, variable duty cicle)
- various I/O (no problem for this)
Until now I have always designed on less complex systems, like PIC24 and PIC18 based board. I know the hardware, but the AM3358 seems too big and complex, and I’m a bit scared of its.
Please, can someone help me?
