Hi ho
Just a quick query...
I am writing a lot of code to do pin bashing and am getting a lot of:
#define FPGA_POWER_PORT_SELECT P6SEL
#define FPGA_POWER_PORT_IN P6IN
#define FPGA_POWER_PORT_OUT P6OUT
#define FPGA_POWER_PORT_DIRECTION P6DIR
#define FPGA_POWER_PIN (1 << 4)
void
powerOn(void)
{
FPGA_POWER_PORT_OUT |= FPGA_POWER_PIN;
FPGA_POWER_PORT_DIRECTION |= FPGA_POWER_PIN;
}
What i would like to do is something like this:
const Msp430Pin l_fpga_power_pin(6, 4);
then:
l_fpga_power_pin = 1; // set pin high
or:
state = l_fpga_power_pin; // check pin level
or what would be really nice:
l_fpga_power_pin = Z; // make pin an input!
when i have a lot of pins it gets pretty messy doing it the current way
and from time to time i get the |= and the &=~ the wrong way around etc. etc.
The PIC compiler we also use has all the standard pins already defined so you
can do:
RB0 = 1; // set bit 0 of PORTB high
or what ever... it uses bit fields but i am not sure if we could do something
similar on the MSP430 with GCC and still get efficient code?
as you have probably guessed i am a hardware type who mostly write VHDL!! maybe
a perl/python/ruby script?
any ideas?
cheers
Tim
