大家好:
我们购买了BT-MSPAUDSOURCE Tools Bluetooth and MSP430 Audio开发板(MSP430F5229),希望提供中断处理程序(最好主设备,从属设备各一套);最好完整一些(宏定义,初始化,执行完整部分)
谢谢!

SuSan, 您好:
按照“蓝牙传输”的理论, 我们希望蓝牙主设备采用“广播方式”发出数据包;蓝牙从设备接收到数据,产生中断,解析数据包内容,进行相应处理!
我们使用的MSP430F5229芯片(开发板是:BT-MSPAUDSOURCE Tools Bluetooth and MSP430 Audio开发板),我们希望以它为基础的
大家好:
您看如下的MSP430的蓝牙接收中断处理程序,改装时注意几项?
MSP430 的 UART 例程您可以参考

大家好:
经过“理论“确认,USCI_A0_VECTOR(HCI_RX_1V8_CC---->MSP430F5229的37管脚:P3.3/UCA0TXD)正是我们蓝牙的主接收端口!
但我们将这个中断处理程序写入后, (
请参考:
// Echo back RXed character, confirm TX buffer is ready first
#if defined(__TI_COMPILER_VERSION__) || defined(__IAR_SYSTEMS_ICC__)
#pragma vector=USCI_A0_VECTOR
__interrupt
void
USCI_A0_ISR(
void
)
#elif defined(__GNUC__)
void
__attribute__ ((interrupt(USCI_A0_VECTOR))) USCI_A0_ISR (
void
)
#else
#error Compiler not supported!
#endif
{
switch
(__even_in_range(UCA0IV,4))
{
case
0:
break
;
// Vector 0 - no interrupt
case
2:
// Vector 2 - RXIFG
while
(!(UCA0IFG&UCTXIFG));
// USCI_A1 TX buffer ready?
UCA0TXBUF = UCA0RXBUF;
// TX -> RXed character
break
;
case
4:
break
;
// Vector 4 - TXIFG
default
:
break
;
}
}
)
程序下载后就跑飞了, 不能跳转到main()入口处!
如何破解?
dirtwillfly, 您好:
我认同您关于工程设置的假设,它的报错信息:
“Verify error at address 0xfff0 on target 0x92 in file 0x84
Verify error at address 0xfff0, Value should be 0x84 but is 0x92.
