Posted on February 20, 2012 at 12:46I was trying to get the ADC working on an STM8S discovery, but left and right alignment setting of the ADC gives different results.
In the file
stm8s_adc1.c of the standard firmware library there is:
/* Left alignment */
{
/* Read MSB firts*/
temph = ADC1->DRH;
/* Then read LSB */
templ = ADC1->DRL;
temph = (u16)((u16)(templ << (u8)6) | (u16)(temph << (u8)8));
}
I suppose that last line should be
temph = (u16)((u16)(templ >> (u8)6) | (u16)(temph << (u8)8));
(shifting the lower byte in the other direction)
Right?
#adc-alignment-shift
