My understanding of the present Woestenberg driver is that it only
supports 16-bit memory-mapped interface.
An additional motivation for my suggestion to access CS8900 via function
call (and/or #define macro) is that it would accomodate 8-bit mode a la
Cirrus AN181.
How about seperating the driver into two modules e.g. CS8900.c and
CS8900if.c? The first would contain the upper-level driver code that
generically handles the CS8900 and connection to the lwIP stack. The
second is modified for each target system to handle the particulars of
how the chip is wired into the system:
memory-mapped vs. I/O mapped vs. simulated bus via
general-purpose I/O pins
big-endian vs. little-endian
8-bit vs. 16-bit access
polled-mode vs. interrupt-driven
Is anyone else interested in 8-bit polled-mode I/O-mapped drivers?
Best regards,
Dick.

Subject: Suggestion for CS8900 driver
I'd like to suggest that the CS8900 driver code be modified to have all
accesses to the chip be made via function calls (or perhaps macros).
This would help in porting to systems where the chip is either I/O
mapped or driven by general-purpose port pins which simulate a bus. In
either case, several instructions are necessary to accomplish the
access. In the I/O mapped case, usually intrinsic functions are needed
(e.g. __inp(), __outp() or similar). In the second case, the register
address is written to one port, the data written to another port, and a
write strobe is asserted & deasserted to a third port.
The present code accesses the CS8900 registers by dereferencing
pointers, which the compiler reduces to a simple memory move instruction
sequence.
Perhaps something along the lines of:
uint CS8900_readreg(uint regaddr);
void CS8900_writereg(uint regaddr, uint value);
//----------------------------------------------------------------------
-----------------------------
// memory-mapped
uint CS8900_readreg(uint regaddr)
{
return *regaddr;
}
void CS8900_writereg(uint regaddr, uint value);
{
*regaddr = value;
}
//----------------------------------------------------------------------
-----------------------------
// I/O-mapped
uint CS8900_readreg(uint regaddr)
{
return __inp(regaddr);
}
void CS8900_writereg(uint regaddr, uint value);
{
__outp(regaddr, value);
}
//----------------------------------------------------------------------
-----------------------------
// port connected
uint CS8900_readreg(uint regaddr)
{
uint retval;
// setup the address
__outp(ADDR, regaddr);
// assert the strobe
__outp(CTRL, 0x01);
// read the data
retval = __inp(DATA);
// de-assert the strobe
__outp(CTRL, 0x00);
// return
return retval;
}
void CS8900_writereg(uint regaddr, uint value);
{
// setup the address
__outp(ADDR, regaddr);
// write the data
__outp(DATA, value);
// assert the strobe
__outp(CTRL, 0x01);
// de-assert the strobe
__outp(CTRL, 0x00);
}
Best regards,
Dick.
