bad soldering. how to change Shift register for BPM common pins

Testing/Troubleshooting
1

I am in trouble. I desoldered alittle to much and now one of my solder pads on my DOUT R3 is bad and wont make a connection with the wire. I am doing this for the bpm display of the seq on its common pins which are normaly on shift reg 6 and at pins  d0, d1 and d2. My d0 solder pad is bad and need to change the connection to another “D” on the same shift register. Do I do this in the seq led txt file?.

#if DEFAULT_BPM_DIGITS_COMMON

movlw DEFAULT_BPM_DIGITS_COMMON - 1

call MIOS_DOUT_SRSet

#endif

;; set digit

lfsr FSR1, BPM_DIGIT_0

movf SEQ_BLM_ROW_CTR, W, BANKED

movff PLUSW1, MIOS_PARAMETER1

#if DEFAULT_BPM_DIGITS_ENABLED == 2

comf MIOS_PARAMETER1, F ; invert for common anode

#endif

#if DEFAULT_BPM_DIGITS_SEGMENTS

movlw DEFAULT_BPM_DIGITS_SEGMENTS - 1

call MIOS_DOUT_SRSet

#endif

You forgot to copy&paste the three lines before this code block:

        ;; duplicate (just because the remaining pins are not used for any other purpose)
        swapf  WREG, W
        iorwf  MIOS_PARAMETER1, F
[/code]









it's a hidden feature (but please don't tell it anybody else before they blame me that it cannot be found in the schematics ;-)) - each common select signal is available on two pins.







In other words: the D0 signal is also available at D4

so d1 is also on d5 and d2 is also on d6?

You are clever! :wink:
