just found iac_freq!=0 with stalled engine and any position, it switch fast from 0 to 100% with unstable freq about 5Hz, but with runing engine all ok.
(it's video - rename to *.3gp)
Map sampling 1ms (best) or 2ms (good too).
map_processing() every event (best), or every rev (good too)
- //sensor_filt[MAP] = 2 * map_samples_summ / map_samples_count;
- void map_processing(void)
- {
- uint16_t t16;
- uint32_t t32;
- t16 = div_65535_x(map_samples_count);
- t32 = mult16_16(map_samples_summ,t16);
- sensor_filt[MAP] = t32 >> 15;
- map_samples_summ = 0;
- map_samples_count = 0;
- }
- has about 3us execute CPU time
vbatt, clt, mat with freq faster than 10Hz - waste of CPU time. I think 4Hz is enough.
