This is by design, and the FET cannot be ramped smoothly up +and down. Turbo is a single level at the top of the ramp, with a big sudden +drop to the next level. + +**Moon**: This light has a pretty bright preflash at moon level, and the +output is unstable so there is very visible ripple. The user can either raise +the ramp floor to a level high enough to avoid these issues, or learn to live +with the ripple and preflash. + diff --git a/hw/lumintop/fw3x-lume1/anduril.h b/hw/lumintop/fw3x-lume1/anduril.h index b208fbc..cd06c6a 100644 --- a/hw/lumintop/fw3x-lume1/anduril.h +++ b/hw/lumintop/fw3x-lume1/anduril.h @@ -8,10 +8,9 @@ * For more information: www.loneoceans.com/labs/ * Datasheets: * - 1634: http://ww1.microchip.com/downloads/en/DeviceDoc/Atmel-8303-8-bit-AVR-Microcontroller-tinyAVR-ATtiny1634_Datasheet.pdf - * - 85: https://ww1.microchip.com/downloads/en/DeviceDoc/Atmel-2586-AVR-8-bit-Microcontroller-ATtiny25-ATtiny45-ATtiny85_Datasheet.pdf */ -#include "lumintop/fw3x-lume1/hwdef.h" +#define HWDEF_H lumintop/fw3x-lume1/hwdef.h // set this light for 50C thermal ceiling #undef DEFAULT_THERM_CEIL @@ -20,60 +19,61 @@ // this light has three aux LED channels: R, G, B #define USE_AUX_RGB_LEDS -// it has no independent LED in the button unlike emisar d4 -//#define USE_BUTTON_LED - // the aux LEDs are front-facing, so turn them off while main LEDs are on #ifdef USE_INDICATOR_LED_WHILE_RAMPING #undef USE_INDICATOR_LED_WHILE_RAMPING #endif -// ../../bin/level_calc.py cube 1 149 7135 0 0.5 1000, with 0 appended to the end. -// for FET PWM (PWM2), all values are 0, except for last value of 1023 -// (with max_pwm set to 1023) #define RAMP_SIZE 150 -//#define PWM1_LEVELS 0,0,0,0,1,1,1,1,2,2,2,3,3,4,4,5,5,6,7,7,8,9,10,11,12,13,14,15,16,17,19,20,22,23,25,26,28,30,32,34,36,38,40,42,45,47,49,52,55,58,60,63,66,70,73,76,80,83,87,91,94,98,102,107,111,115,120,124,129,134,139,144,150,155,160,166,172,178,184,190,196,203,209,216,223,230,237,244,252,259,267,275,283,291,299,308,316,325,334,343,353,362,372,382,392,402,412,423,433,444,455,466,478,489,501,513,525,538,550,563,576,589,602,616,630,644,658,672,687,701,716,731,747,762,778,794,810,827,844,861,878,895,913,930,948,967,985,1004,1023,0 -#define PWM1_LEVELS 1,1,1,1,2,2,2,2,3,3,3,4,4,5,5,6,6,7,8,8,9,10,11,12,13,14,15,16,17,18,20,21,23,24,26,27,29,31,33,35,37,39,41,43,45,48,50,53,56,58,61,64,67,70,74,77,80,84,88,91,95,99,103,108,112,116,121,125,130,135,140,145,150,156,161,167,173,178,184,191,197,203,210,217,223,230,238,245,252,260,268,275,283,292,300,308,317,326,335,344,353,363,372,382,392,402,413,423,434,445,456,467,478,490,502,514,526,538,551,563,576,589,603,616,630,644,658,672,687,702,717,732,747,763,778,794,811,827,844,861,878,895,913,931,949,967,985,1004,1023,0 -#define PWM2_LEVELS 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1023 + +// level_calc.py 5.01 1 149 7135 0 0.2 2000 --pwm 32640 +// regulated channel: 16-bit PWM+DSM for low lows and very smooth ramp +#define PWM1_LEVELS 0,1,2,3,4,5,6,7,9,10,12,14,17,19,22,25,29,33,37,41,46,51,57,63,70,77,85,93,103,112,123,134,146,159,172,187,203,219,237,256,276,297,319,343,368,394,422,452,483,516,551,587,625,666,708,753,799,848,900,954,1010,1069,1131,1195,1263,1333,1407,1483,1563,1647,1734,1825,1919,2017,2119,2226,2336,2451,2571,2694,2823,2957,3095,3239,3388,3542,3702,3868,4040,4217,4401,4591,4788,4992,5202,5419,5644,5876,6115,6362,6617,6880,7152,7432,7721,8018,8325,8641,8967,9302,9647,10003,10369,10745,11133,11531,11941,12363,12796,13241,13699,14169,14652,15148,15657,16180,16717,17268,17834,18414,19009,19620,20246,20888,21546,22221,22913,23621,24348,25091,25853,26634,27433,28251,29089,29946,30823,31721,32640,0 +// DD FET: 8-bit PWM (but hardware can only handle 0 and MAX) +#define PWM2_LEVELS 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,255 #define DEFAULT_LEVEL 56 #define MAX_1x7135 149 -// TODO: test if underclocking works on lume1 -//#define HALFSPEED_LEVEL 14 -//#define QUARTERSPEED_LEVEL 5 -// don't slow down at low levels;
