13:22 | vpeter | jnettlet: Can we talk privately? |
13:23 | jnettlet | sure just pm me. I will be back and forth to my computer for a half hour or so |
16:40 | topi` | I have ttymxc0, ttymxc2 and ttymxc3 on my HB Gate. Which one of these goes to the Mikrobus UART pins? |
17:31 | jnettlet | topi`, ttymxc3. ttymxc0 is the serial console, ttymxc2 is for the BT module on the microsom and ttymxc3 is the mikrobus connector |
17:35 | topi` | thanks, I'll proceed with wiring :) |
17:36 | topi` | gotta do some sunday work, my balance is full of minus hours :( |
18:01 | topi` | this is stupid question, but if I have a module that wants 3.3V for its UART, how do I know if the UART pins in the Mikrobus are going to drive 3.3V or 5V? |
18:01 | topi` | I will use 3 wires - GND, TX and RX |
18:33 | jnettlet | All the signaling is 3.3v |
18:34 | jnettlet | We don't support 5V signals on any of our boards |
19:35 | topi` | OK |
19:35 | topi` | so the Mikrobus spec does not force a certain level on those UART pins? |
19:36 | topi` | there are separate lines for +3.3V and +5V so Mikrobus seems to be designed "voltage agnostic" |
19:42 | rabeeh | yeah; a bit problematic |
19:42 | rabeeh | 3.3v on HB2 |
