I've been trying to attach a serial device to the beaglebone black and communicating with it over UART 1 (p9_24 and p9_26) with no success.
In part because I am new to linux and have no idea how to ping/check connected devices over terminal and NO prior electronic knowledge to insure the device is properly wired up to the beaglebone black. I've attached a wiring diagram below. Can someone please confirm: 1. That I've wired it correctly by looking at the diagram 2. That the supplied voltage from the BBB is sufficient to power the attached device (3.3V TTL) Mapping explained (see device diagram): Pin 1 VCC (P) to 3.3Vdc on the BBB (p9_03) Pin 2 GND (G) to GND on the BBB (p9_01) PIN 3 TXD (O) to UART1 RX on the BBB (p9_26) PIN 4 RXD (I) to UART1 TX on the BBB (p9_24) <https://lh3.googleusercontent.com/-ydiICNM4U4I/VHQ-aW5xjzI/AAAAAAAAAnw/wJnRP_pSdso/s1600/BBBSerialDiagram.png> Regards Pieter -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
