supports 48MHz system frequency in terms of product functions. This series has the characteristics of wide voltage, single-wire debugging, low power consumption, ultra-small package and so on. Provide common peripheral functions, built-in 1 set of DMA controller, 1 set of 10-bit analog-to-digital conversion ADC, 1 set of op amp comparator, multiple sets of timers, standard communication interfaces such as USART, I2C, SPI, etc. The rated working voltage of the product is 3.3V or 5V, and the working temperature range is -40'C~85'C industrial grade. + +PeripheralVersion=1.6 +MCU=CH32V003F4P6 diff --git a/code/ch32v003_bootloader/CH32V003_BL.wvproj b/code/ch32v003_bootloader/CH32V003_BL.wvproj new file mode 100644 index 0000000..7a53b06 Binary files /dev/null and b/code/ch32v003_bootloader/CH32V003_BL.wvproj differ diff --git a/code/ch32v003_bootloader/core/core_riscv.c b/code/ch32v003_bootloader/core/core_riscv.c new file mode 100644 index 0000000..fa82ae0 --- /dev/null +++ b/code/ch32v003_bootloader/core/core_riscv.c @@ -0,0 +1,276 @@ +/********************************** (C) COPYRIGHT ******************************* + * File Name : core_riscv.c + * Author : WCH + * Version : V1.0.0 + * Date : 2022/08/08 + * Description : RISC-V Core Peripheral Access Layer Source File + ********************************************************************************* + * Copyright (c) 2021 Nanjing Qinheng Microelectronics Co., Ltd. + * Attention: This software (modified or not) and binary are used for + * microcontroller manufactured by Nanjing Qinheng Microelectronics. + *******************************************************************************/ +#include + +/* define compiler specific symbols */ +#if defined(__CC_ARM) + #define __ASM __asm /*!< asm keyword for ARM Compiler */ + #define __INLINE __inline /*!< inline keyword for ARM Compiler */ + +#elif defined(__ICCARM__) + #define __ASM __asm /*!< asm keyword for IAR Compiler */ + #define __INLINE inline /*!< inline keyword for IAR Compiler.
