BPM LED digits configuration

[Rio]

Hi all,

 

i have build up the BPM LED digits exactly like: http://www.ucapps.de/midibox_seq/mbseq_v4_bpm_digits.pdf

 

but i'm not sure how to setup it correct, because all LEDs of every segment are "on", when I start and run a sequence. I use these 7 segment digits: http://www.dl9usa.de/Ebay/009/vqb37.gif

 

and these MBSEQ_HW.V4 settings (which must be wrong :D):

##################################################
# Optional BPM digits
##################################################

# set to 1 or 2 to enable the 3 optional BPM digits
# 0: BPM digits disabled
# 1: BPM digits with common cathode
# 2: BPM digits with common anode
BPM_DIGITS_ENABLED 1

# define the DOUT shift register to which the segments are connected (0=disabled)
BPM_DIGITS_SEGMENTS_SR 5

# define the DOUT SR and pin to which the common pins are connected
# we are counting from right to left
# Example: 140.5 BPM: (COMMON1 = .5, COMMON2=0., COMMON3=4, COMMON4=1)
#                       SR  Pin
BPM_DIGITS_COMMON1_PIN   4   3
BPM_DIGITS_COMMON2_PIN   4   2
BPM_DIGITS_COMMON3_PIN   4   1
BPM_DIGITS_COMMON4_PIN   4   0

Hi,

 I had some problems with the bpm wiring also and discovered that the segment  wiring is inverted (I think the common pin also). There is a thread about it somewhere :rolleyes: . 

You probably have also another problem because ALL segments should not be on but without a picture of your actual wiring it's hard to

say where the problem is. The data says common cathode but perhaps try with common anode...
