Here are the lines you are interested in when setting up the modes in bistro.
First is the ramp table that converts the raw PWM numbers into “modes”
#define ONE7135 14
#define ALL7135s 27
#define RAMP_7135 3,4,7,11,18,27,40,57,77,103,133,169,211,255,255,255,255,255,255,255,255,255,255,255,255,255,0,255,255,255,255,255,255,255,255,255,255,255,255,0
#define RAMP_7135s 0,0,0,0,0,0,0,0,0,0,0,0,0,0,11,22,35,49,64,82,101,122,144,169,195,224,255,255,255,255,255,255,255,255,255,255,255,255,255,0
#define RAMP_FET 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,9,24,39,55,73,91,111,132,154,177,202,228,255
Notice that I zeroed out the one7135 channel at the 27th ramp in order to allow the bank of 7135’s to run without the single 7135 engaged. Simply return that zero to a 255 to re-enable it.
Here is where the mode groups are setup. I have this firmware set by defualt to use mode group 3 and enable moon mode. Moon mode in this firmware is 3 PWM as that is the 1st ramp table value. So that takes care of your first mode.
The code for the mode groups, the bolded group is the default one and the one that should be close to what you are looking for:
Now I am not totally sure how many mA a 7 as the first mode will draw but you can simply adjust it up or down until you get the brightness you are looking for. I am guessing it will be around 50ma since that correlates to a 40pwm in the ramp table.
You should be able to adjust from there pretty easily.
Here is the code for the above setup: PD68-Tripledown
