hei,
i have 2 of them here,
booth not working , they have not been working till the day
i first used my code, but since it did not work i uploadet the tutorial_16 svn
and edit the code for what I think is to be set for AOUT_NG:
// initialize AOUT module AOUT\_Init(0); // configure interface // see AOUT module documentation for available interfaces and options aout\_config\_t config; config = AOUT\_ConfigGet(); config.if\_type = AOUT\_IF\_TLV5630; config.if\_option = 0; config.num\_channels = 8; // INTDAC: only 2 channels supported, 8 channels pre-configured for your own comfort config.chn\_inverted = 1; AOUT\_ConfigSet(config); AOUT\_IF\_Init(0);
The LED is lighting up, and i followed the connection from the chip 541 till the DAC >>> from the beginning i have done right; to be sure for that, i copyed all info i found about that weired connection:
and i think there is something wrong with the documentation, the photo of the ng shows i (i think) a different pinning) also in every shematic or tutorial or wiki you get other names for that pins - its very confusing - can anybody check my multicolor painted connections in graphic above - thanx
for that i removed the Discovery board and “biept out” all connections, i finally replaced the 541 on the core… R33 is also stuffed, and it is a 1K network - all right -but solved nothing.
i also tryed a second core, that i have (i have a pair of them),
i also measured carefully direct on the DAC GND and +5V all are there.
I measured DAC-A output aka “pin 0” and i have 0V to Digital Ground > so nothing.
I connected ±12V from a doepfer PSU2 - right from the beginning on…
and as far as i can say i have not heated the DAC to much while soldering, i made it quick and clean with a Weller Station where i can change the temperature…
i stuck a bit… maybe there is something wrong with the inital code (posted above)
thx for any tip
