From 9f28e53c71d28d04e2775c59944d2887a99f1e86 Mon Sep 17 00:00:00 2001 From: Josh Rahm Date: Sun, 22 Nov 2020 01:06:30 -0700 Subject: Large reorganization. What was in core/ is now moved to arch/stm34l4xxx/peripherals. This new directory is *supposed to* to contain raw header files defining just the pertinent register structures for the various peripherals. Peripheral management belongs somewhere in the new `kern/..` directories. This is not completely the case at the moment, so more refactoring needs to be done. What was sitting in the root has now been moved into the kern/ directory. The kern/ directory is to contain everything else other than raw device register definitions. The root of the kern/ tree is reserved for standard library-esque headers. The kern/ directory contains management systems for that peripheral. (At the moment DMA is the only peripheral with a decent management system.) Preferably these peripheral systems should only include their correlating header in arch/stm34l4xxx/peripherals, and use other management systems for handling other peripherals rather than manipulating their raw registers directly. (Though this ideal will require much more critical mass of management systems.) --- 02-usart/include/core/nvic.h | 46 -------------------------------------------- 1 file changed, 46 deletions(-) delete mode 100644 02-usart/include/core/nvic.h (limited to '02-usart/include/core/nvic.h') diff --git a/02-usart/include/core/nvic.h b/02-usart/include/core/nvic.h deleted file mode 100644 index c761574..0000000 --- a/02-usart/include/core/nvic.h +++ /dev/null @@ -1,46 +0,0 @@ -#ifndef NVIC_H_ -#define NVIC_H_ - -#include "arch.h" -#include "common.h" - -typedef __IO struct { -#define nvic_intlinesnum (0x0F << 0) - uint32_t ict_r; /* Interrupt control type register. */ - - uint8_t reserved0[0xF8]; - - uint32_t ise_r[8]; - - uint8_t reserved1[0x60]; - - uint32_t ice_r[8]; - - uint8_t reserved2[0x60]; - - uint32_t isp_r[8]; - - uint8_t reserved3[0x60]; - - uint32_t icp_r[8]; - - uint8_t reserved4[0x60]; - - uint32_t iab_r[8]; - - uint8_t reserved5[0xE0]; - - uint32_t ip_r[60]; -} nvic_t; - -static_assert(offsetof(nvic_t, ise_r) == 0x00FC, "Offset check failed"); -static_assert(offsetof(nvic_t, ice_r) == 0x017C, "Offset check failed"); -static_assert(offsetof(nvic_t, isp_r) == 0x01FC, "Offset check failed"); -static_assert(offsetof(nvic_t, icp_r) == 0x027C, "Offset check failed"); -static_assert(offsetof(nvic_t, iab_r) == 0x02FC, "Offset check failed"); -static_assert(offsetof(nvic_t, ip_r) == 0x03FC, "Offset check failed"); - -#define NVIC (* (nvic_t*) NVIC_BASE) - - -#endif /* NVIC_H_ */ -- cgit
