From b14d0afe86966b91ad6a40816439cdc34602b49e Mon Sep 17 00:00:00 2001 From: Nao Pross Date: Tue, 4 Jul 2017 11:35:23 +0200 Subject: new structure for process management, structures to discuss the idea behind kernel/include/progman.h was good but the implementation was very not unix-like, so I made a new file under kernel/include/process.h that will implement the same features other changes: - move usart register structs definitions outside of the device - remove old build files - delete boot.h and boot_loader.h (as they weren't used by anything) - change on makefile to build binary with `makebin` instead of `xxd` - new file memory.h to implement memory mapping and mmu control - new type `uint` in types.h --- sw/z80/kernel/include/drivers/pio.h | 35 +++++++++++++++++++++++++++++++++++ 1 file changed, 35 insertions(+) create mode 100644 sw/z80/kernel/include/drivers/pio.h (limited to 'sw/z80/kernel/include/drivers/pio.h') diff --git a/sw/z80/kernel/include/drivers/pio.h b/sw/z80/kernel/include/drivers/pio.h new file mode 100644 index 0000000..5d289ca --- /dev/null +++ b/sw/z80/kernel/include/drivers/pio.h @@ -0,0 +1,35 @@ +#ifndef __PIO_H__ +#define __PIO_H__ + +#include "devices.h" +#include "types.h" + +#define PIO_A 0 +#define PIO_B 1 + +#define PIO_MODE_0 0 +#define PIO_MODE_1 1 +#define PIO_MODE_2 2 +#define PIO_MODE_3 3 + +#define PIO_INT_ACTIVE_HIGH (1<<5) +#define PIO_INT_AND_MODE (1<<6) +#define PIO_INT_ENABLE (1<<7) + + +void _pio_data(int port, uint8_t data); +void _pio_command(int port, uint8_t cmd); + +void pio_set_mode(int port, int mode); +void pio_set_interrupts(int port, int control); +void pio_set_interrupts_mask(int port, uint8_t mask); +void pio_set_io(int port, uint8_t io); + +// uint8_t pio_read_data(int port); + +inline int pio_read_pin(int port, uint8_t pin); +inline void pio_write_pin(int port, uint8_t pin); + +// TODO: implement mode (in/out/both) and interrupt vector + +#endif // __PIO_H__ -- cgit v1.2.1
