Channel names

[rgrr]

Hello pico-code,

here is my PR for "channel names from probe".

Don't know, if this is intended: you have tabs in your code. Or is that what the libsigrok guys want?

probe side

example code for the probe side:

            case 'N':
                // return channel name
                // format is N[AD]yy, A=analog, D=digital, yy is channel #
                ret = false;
                if (d->cmdstr_ndx >= 4) {
                    tmpint = atoi(d->cmdstr + 2);
                    if (d->cmdstr[1] == 'A'  &&  tmpint >= 0  &&  tmpint < SR_NUM_A_CHAN) {
                        sprintf(d->rspstr, "ADC%d", tmpint);
                        ret = true;
                    }
                    else if (d->cmdstr[1] == 'D'  &&  tmpint >= 0  &&  tmpint < SR_NUM_D_CHAN) {
                        sprintf(d->rspstr, "GP%d", tmpint + SR_BASE_D_CHAN);
                        ret = true;
                    }
                }
                else if (d->cmdstr[1] == '?') {
                    strcpy(d->rspstr, "ok");
                    ret = true;
                }
                break;

Actually not very complicated ;-)

sorry for the tardiness. Originally I didn't touch this because I was trying to minimize changes waiting for mainline acceptance.
sigrokproject#256 should have a similar fix to allow channel renaming.
