TSC2007IPWR TLE4275QKVURQ1库存物料，客户改板，留下这两颗库存，有需要的话来联系哦

SDK版本是simplelink_cc13x2_26x2_sdk_4_30_00_54。在例程simle_peripheral上进行的修改. 通过GATT_Notification函数操作特征值4.通过sysconfig把 MAX_PDU_SIZE 修改为255.在周期性任务中调用了一次HCI_LE_SetDataLenCmd(connList[0].connHandle,251,2120)。但是还是不能一次性传输超过20个字节。请问该怎么做才能实现超过20个字节的发送呢？谢谢。

win10系统，altium designer20.0.2装好以后关联出了问题，如图： .c文件关联被改成x2.exe，怎么改都改不动，删除所有x2.exe的注册表项也没用[em:8:] [attach]1571912[/attach]

求高手点拨。 想要使用单通道连续采样，工作在最高采样率。但是用TI的例程实测，采样率都低太多。 时钟用ADC内部振荡器，约5MHz，2个采样周期+13个转换周期，计算下来应该4us左右采一个点。 但是，输入5kHz的正方波——100us高电平， 采下来高电平就采到2、3个值，低电平采到1、2个值，感觉30多us才采了一个点。 IAR编译，自己画的开发板，代码如下： #include #include "..\com\delay.h" #define Num_of_Results 30 static unsigned int results[Num_of_Results]; // Needs to be global in this // example. Otherwise, the // compiler removes it because it // is not used for anything. static unsigned int index = 0; unsigned char ir; void main(void) { WDTCTL = WDTPW+WDTHOLD; // Stop watchdog timer /* for test */ P1DIR |= BIT0; // 上电指示 P1OUT |= BIT0; P2DIR |= BIT6; // ADC12CLK P2SEL |= BIT6; // Vref+ 在pin7测试 P5DIR |= 0x70; // P5.6,5,4 outputs P5SEL |= 0x70; // P5.6,5,4 options, ACLK, SMCLK, MCLK /**/ P6SEL |= 0x01; // Enable A/D channel A0 ADC12CTL0 = ADC12ON + SHT0_2 + REFON + MSC; // Turn on ADC12, set sampling time ADC12CTL1 = SHP + CONSEQ_2; // Use sampling timer, single-repeat mode, default: ADC12CLK = ADC12OSC(about 5MHz) ADC12MCTL0 = SREF_1; // Vr+=Vref+ ADC12IE = 0x01; // Enable ADC12IFG.0 delay_ms(20); ADC12CTL0 |= ENC; // Enable conversions ADC12CTL0 |= ADC12SC; // Start conversion _BIS_SR(LPM0_bits + GIE); // Enter LPM0,Enable interrupts } #pragma vector=ADC12_VECTOR __interrupt void ADC12ISR (void) { results[index] = ADC12MEM0; // Move results index = (index+1)%Num_of_Results; // Increment results index, modulo }

void setclock(void) { WDTCTL = WDTPW + WDTHOLD; // watchdog timer setup if (CALBC1_1MHZ ==0xFF || CALDCO_1MHZ == 0xFF) { while(1); // If cal constants erased, trap CPU!! } BCSCTL1 = CALBC1_1MHZ; // Set range DCOCTL = CALDCO_1MHZ; // Set DCO step + modulation IFG1 &= ~OFIFG; } void settimer(){ TACTL=TACLR; TACTL=TASSEL_2+MC_2; TACCTL1=CM_3+CCIS_0+CAP+CCIE; TACCTL1&=~CCIFG; _EINT(); } void setgpio(){ P1DIR=0X01; P1OUT=0X01; P1SEL=BIT2+BIT1; } void main(void) { setclock(); setgpio(); settimer(); while(1); } #pragma vector=TIMER0_A1_VECTOR __interrupt void Timer_A (void) { if(TACCTL1&CCIFG){ TACCTL1&=CCIFG; //CC=CCR1-C; //C=CCR1; P1OUT^=BIT0; } }

目前我从事摩托车行业，准备像汽车行业一样做OTA远程升级，需要TBOX和网络的支持，但我目前对我使用的MCU(TI的TMS320F28035)的了解仅仅是在bootloadr的时候刷新数据，问题就是还有没有其它需要了解的知识。

WAKE_UP_RTC_MAX_TIME - 睡眠唤醒所需时间，根据不同睡眠类型取值可分为：睡眠模式/下电模式 - 65(默认) 这个单位是什么？ms？还是计数值？

在自己的设计中调用Quartusii生成的firIP核，我的设计是verilg，fir的顶层是verilog，功能实现全是vhdl。然后在modelsim中进行仿真，仿真时提示错误Instantiation of 'fir_top_0002' failed.quartus版本是13.0 modelsim版本是 modelsim_altera 10.1d 百度也查不到。。求助高手。。

uint32 Systick_Config (uint32 ticks ) { if ( (ticks-1UL) >0xFFFFFFUL) { return 1UL; } return 0UL; } 疑问，当ticks的值为0时，函数返回值是多少？
