Hello,
I know the snippet of code below in Tinyos 1.x /tos/platform/atm1281/HPLADCM.nc
is marked for being registered as an interrupt. I'm trying to understand how
the software knows to run this piece of code when the ADC Conversion is
complete. The ADC part of SIG_ADC is listed in the Atmel 1281 datasheet (pg
106) as the name of the interrupt vector that signals a conversion is complete,
however, when I search source code info on the TWI interrupt vector, there is
no SIG_TWI in the nesc code, but instead SIG_2WIRE_SERIAL, and nothing to map
2WIRE_SERIAL to TWI.
So how does TOSH_SIGNAL(SIG_ADC) get associated with the ADC conversion
complete interrupt vector? Which file has this information? I'm just teaching
myself by walking through sample code.
TOSH_SIGNAL(SIG_ADC) {
uint16_t data = inw(ADCL);
data &= 0x3ff;
sbi(ADCSRA, ADIF);
cbi(ADCSRA, ADEN);
__nesc_enable_interrupt();
signal ADC.dataReady(data);
}
