I've used the second ball (and disabled the first) when it was required for
a device. For example spi2_d1 uses P9.21b, so I disable P9.21a by setting
it to PULL_DIS | MUX_MODE15. Be careful about pull-up/pull-down contention
between connected balls. Use the same pull mode for both or set the
Hi!
I had a question regarding the I/O pins on BB-AI. I've noticed that on some
of the pins on the expansion headers, there are two AM5728 balls connected
to the same pin (through zero-ohm resistors). I've noticed these
particularly on the pins used for the LCD.
I was wondering, what's the
Okay, so based on a discussion on element14 and out of my own curiosity, I
am attempting to set a header pin to PWM but I am not having much luck.
Looking again at the am5729-beagleboneai-roboticscape.dts as an example, I
set P8_23 (gpio22) as follows:
* DRA7XX_CORE_IOPAD(0x3794, PIN_OUTPUT |
I found if I remove all of the usrx LED entries in the blinkLED.js except
usr3 and the system does not seem to become unresponsive after running the
example. I did move to P8_23 gpio22 to attempt to set a PWM pin for anther
example.
Ex:
const leds = ["USR3", "P8_23"];
//const leds = ["USR0",
