In CC2420ControP.nc, there is part of code to set MDMCTRL0.
However I tried to copy this code and set Mdmctrl1, but that does not work
void writeMdmctrl0() {
atomic {
call MDMCTRL0.write( ( 1 << CC2420_MDMCTRL0_RESERVED_FRAME_MODE ) |
( addressRecognition << CC2420_MDMCTRL0_ADR_DECODE ) |
( 2 << CC2420_MDMCTRL0_CCA_HYST ) |
( 3 << CC2420_MDMCTRL0_CCA_MOD ) |
( 1 << CC2420_MDMCTRL0_AUTOCRC ) |
( (autoAckEnabled && hwAutoAckDefault) << CC2420_MDMCTRL0_AUTOACK ) |
( 0 << CC2420_MDMCTRL0_AUTOACK ) |
( 2 << CC2420_MDMCTRL0_PREAMBLE_LENGTH ) );
}
// Jon Green:
// MDMCTRL1.CORR_THR is defaulted to 20 instead of 0 like the datasheet says
// If we add in changes to MDMCTRL1, be sure to include this fix.
