【愛普特APT32F110開發(fā)板工程師測評1】printf花式表白

APT32F110X 系列串口功能強大：可以完成STM32串口功能，驅(qū)動AT物聯(lián)網(wǎng)模組不在話下。

資源串行通信接口：1 × I2C，3 x UART，1 x USART，1 x SPI，1 x SIO

通用異步收發(fā)器（UART）

3個通道

8位數(shù)據(jù)長度，支持校驗位(奇偶校驗，0/1校驗)

單獨的8x8位收發(fā)FIFO

可編程的波特率

同步異步收發(fā)器（USART）

• 1個通道
• 支持5、6、7和8位數(shù)據(jù)長度
  
• 單獨的8x8位收發(fā)FIFO可編程的波特率
• 校驗位，幀檢測和緩存溢出錯誤報告
  
• 支持Loop-back模式
• 支持同步全雙工模式
• 支持LIN總線協(xié)議：LIN1.2或者LIN2.0
• 支持智能卡協(xié)議：ISO7816-3兼容

編程實踐：

時鐘配置

void system_init(void)

{

CK_CPU_DISALLNORMALIRQ;

csi_iwdt_close();//close iwdt

csi_sysclk_config();//sysclk config

csi_get_sclk_freq();

csi_get_pclk_freq();

csi_tick_init();

csi_clk_calib();

CK_CPU_ENALLNORMALIRQ;

}

串口配置：115200波特率

__attribute__((weak)) void board_init(void)

{

//console config for print

console.uart_id = (uint32_t)CONSOLE_IDX;

console.baudrate = 115200U;

console.tx.pin = CONSOLE_TXD;

console.tx.func = CONSOLE_TXD_FUNC;

console.rx.pin = CONSOLE_RXD;

console.rx.func = CONSOLE_RXD_FUNC;

console.uart = (csp_uart_t *)(APB_UART0_BASE + CONSOLE_IDX * 0x1000);

console_init(&console);

#ifdef CONFIG_USER_PM//low power manage switch

if(csi_get_rst_reason() & RST_SRC_SNOOZE_WKUP)//wake up from snooze mode

{

g_tPmCore.wkup_frm_snooze = (void *)csi_ureg_read(USER_REG0);

if(g_tPmCore.wkup_frm_snooze)

g_tPmCore.wkup_frm_snooze();

}

else if(csi_get_rst_reason() & RST_SRC_SHD_WKUP)//wake up from shutdown mode

{

g_tPmCore.wkup_frm_shutdown = (void *)csi_ureg_read(USER_REG0);

if(g_tPmCore.wkup_frm_shutdown)

g_tPmCore.wkup_frm_shutdown();

}

#endif

}

花式打印表白啊，程序員哄女孩子的利器！！

先上圖案：

代碼實現(xiàn)很簡單， printf打印就可以了：

int main()

{

//start_system();

system_init();

board_init();

csi_pin_set_mux(PB02, PB02_OUTPUT); //PA06 output

csi_pin_set_high(PB02); //PA06 output high;
