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/drivers/pio.c | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) create mode 100644 sw/z80/kernel/drivers/pio.c (limited to 'sw/z80/kernel/drivers/pio.c') diff --git a/sw/z80/kernel/drivers/pio.c b/sw/z80/kernel/drivers/pio.c new file mode 100644 index 0000000..e29383f --- /dev/null +++ b/sw/z80/kernel/drivers/pio.c @@ -0,0 +1,19 @@ +#include "drivers/pio.h" + +static uint8_t *pio_port = (uint8_t *) ADDR_DEV_PIO; +static uint8_t *pio_ctrl = (uint8_t *) (ADDR_DEV_PIO + 2); + +void _pio_data(int port, uint8_t data) +{ + *(pio_port + port) = data; +} + +void _pio_command(int port, uint8_t cmd) +{ + *(pio_ctrl + port) = cmd; +} + +void pio_set_mode(int port, int mode) +{ + +} -- cgit v1.2.1
