Sensoray 526 analogy driver
PATCH 1/1 Sensoray 526 analogy driver
Hi,
I try to configure sensoray counters to generate PWM signal
#define SUBD_CNT 0
#define SUBD_AI 1
#define SUBD_AO 2
#define SUBD_DIO 3
insn.type = A4L_INSN_CONFIG;
insn.idx_subd = SUBD_COUNTER;
insn.chan_desc = CHAN(channel); insn.data_size = sizeof(dataC) / sizeof(dataC[0]); insn.data = data;
data[0] = A4L_INSN_CONFIG_GPCT_PULSE_TRAIN_GENERATOR; data[1] = cmReg.value;
data[2] = down_ticks;
data[3] = up_ticks;
ret = a4l_snd_insn(&dsc, &insn);
in a4l_do_insn the subdevice is check in this way but the test for counter, and I think also for dio, fails due to A4L_SUBD_MASK_SPECIAL bit
#define A4L_SUBD_UNUSED (A4L_SUBD_MASK_SPECIAL|0x1) #define A4L_SUBD_COUNTER (A4L_SUBD_MASK_SPECIAL|0x40) #define A4L_SUBD_DIO (A4L_SUBD_MASK_SPECIAL|0x20)
/* Checks the subdevice's characteristics */
if ((subd->flags & A4L_SUBD_UNUSED) != 0) { __a4l_err("a4l_do_insn: wrong subdevice selected 0x%X\n",subd->flags); return -EINVAL;
}
there is something wrong or I miss something ?
TIA

You miss nothing. There was a bug in the subdevice's flags checking line:
The problem is here: if ((subd->flags & A4L_SUBD_UNUSED) != 0) {
I fixed it in my git repo one week ago.
Either you clone my git repot or you wait for the pull request I will make tonight.
