Hi, I am currently trying to use the HIO8 interface on the DSP56303EVM for GPIO. However, I cannot get anything to the output pins.... Here is the code I used to setup the HPCR and HDDR registers HPCR EQU $FFFFC4 ; host control register HDDR EQU $FFFFC8 ; host GPIO data direction register HDR EQU $FFFFC9 ; host GPIO data register bclr #HEN,x:HCR ; disable host interface bset #HGEN,x:HCR ; enable GPIO on the host interface movep #HDDR_VALUE,x:HDDR ; configure the 8 bits as outputs (8 bits I/Q output) However when do (for example)... bset #0,x:R i don't observe anything on the output pins... One other questions.... which pins does bit 0 and bit 1 map too ? pin 11-12 or pin 1-2 (of J3) ? Thanks in advance, Guillaume |
