Im getting a register allocation failed error pointing to this type of code:
/***************************************************
* checks if two angles(sectors) are adjacent
**************************************************/
inline bool_t isSectorAdjacent(uint16_t new_angle)
{
int16_t angle_diff = abs(new_angle - rotpos.angle);
return angle_diff <= 60 or (new_angle == 330 and rotpos.angle == 30);
}
/*****************************************
* get current sector with offset
****************************************/
int16_t getSector(void)
{
int16_t sector;
if(config.adv_sector_fetching)
{
uint16_t GetCurrentHallAngle(void);
float fastNormDeg(float);
uint16_t current_sector = GetCurrentHallAngle();
bool_t is_sector_adj = isSectorAdjacent(current_sector);
if(is_sector_adj) sector = (int16_t)current_sector;
else sector = (int16_t)rotpos.angle; // if adjacency check fails just return normal version
}
else sector = (int16_t)rotpos.angle;
sector += (rotpos.dir == REVERSE ? config.bwdsectoroffset : config.fwdsectoroffset);
return fastNormDeg(sector);
}
Disclaimer: this snipped is by no means efficient it was just part of a little trial and error phase where i tried to fix an issue.
Kind Regard Tobias F.
