VL (21.12.2015 18:09, просмотров: 1) ответил VL на Kinetis M0 SPI - как-то странно, не ставится бит разрешения. Почему так может быть?Fixed: Ошибка в определениях ИАРа ver 7202. ИАР:
typedef struct SPI_MemMap {
uint8_t C1; /**< SPI control register 1, offset: 0x0 */
uint8_t C2; /**< SPI control register 2, offset: 0x1 */
uint8_t BR; /**< SPI baud rate register, offset: 0x2 */
uint8_t S; /**< SPI status register, offset: 0x3 */
uint8_t RESERVED_0[1];
uint8_t D; /**< SPI data register, offset: 0x5 */
uint8_t RESERVED_1[1];
uint8_t M; /**< SPI match register, offset: 0x7 */
} volatile *SPI_MemMapPtr;
