DSPS example

嗨，对话，

Thanks a lot for your quick reply.

My code as in the attached, there seems no unconsumed data.

我仍然认为spi I与uart冲突

因为uart在我的项目中没有用处，

can you help to tell me how to stop it? then I can test if uart conflicts with spi.

Thanks

(I test spi in other example, it works well)

我认为spi是导致冲突的唯一原因

Thanks

Benjamin

嗨，对话，

Boot from system, there is little interact between uart

My major modification as following

void timer\u回调（void）

{

int iSSS;

iSSS=spi\ U事务（0x80040001）；

/ /空间站= (iss > > 5) &0xFFFF;

//iSSS/=64;

//iSSS=1023;

拱门打印（“TTTTT\t”）；

}

#ifdef CFG_PRINTF_UART2

GPIO\U配置引脚（2，8，输出，PID\U UART2\U TX，false）；

GPIO_ConfigurePin( 2, 9, INPUT, PID_UART2_RX, false );

#endif

GPIO\u ConfigurePin（0，0，输出，PID\u SPI\u CLK，false）；

GPIO_ConfigurePin( 0, 2, OUTPUT, PID_SPI_EN, true );

GPIO\u ConfigurePin（0，5，INPUT，PID\u SPI\u DI，false）；

GPIO\u ConfigurePin（0，6，OUTPUT，PID\u SPI\u DO，false）；

SPI\u Pad\u t SPI\u CS\u Pad；

spi_CS_Pad.pin = 2; //2 or

spi\ CS公司_Pad.port =0; // SPI\ U端口；

spi\ u init（&spi\ u CS\ u Pad，spi\ u MODE\ u 32位，spi\ u ROLE\ u MASTER，spi\ u CLK\ u IDLE\ u POL\ u LOW，spi\ u PHA\ u MODE\ u 0，spi\ u MINT\ u DISABLE，spi\ u XTAL\ u DIV\ u 8）；

timer_init();

timer0_register_callback(timer_callback);

The output as following, then it stops, about 15s, it fails. attached is the whole doc that modified.

嗨，对话，

Total 4 documents modified,all in the above .pdf simply copy them and paste into the corresponding doc, then you can test it.

非常感谢你的帮助

嗨，对话，

I increased DB_HEAP_SZ 2 times and 4 times, but still it crashes, the difference is the bigger size the DB_HEAP_SZ, the longer time it took to crash.

can you help to say where the memory is used?

Do you have other way to avoid crashing ?

Thanks

Benjamin

嗨，对话，

以前我用的是SDK3.xuart\u slave，DB\u HEAP\u SZ是1024，还是很好用的，我按照你的建议换了新的SDK，但是崩溃了，如上图所示，我觉得是串口内存消耗的原因，因为我的项目没有用到串口，你能帮我建议怎么停止串口吗？

Thanks

Benjamin

嗨，对话，

Maybe spi conflict with other interrupt?

因为spi可以独立工作。

Thanks

嗨，对话，

Following 3 files modified:

主拱门

user_periph_setup.c

da1458x\配置\基本.h

I copied the contents of the 3 files and their modifications in the PDF document, the 3 are separated by ///////////you can find the modifications where there is //Benjamin added.

I tested the same code with SDK3.x uart_slave, and it works.

Thanks

嗨，对话，

My project is to use dsps to read throngh spi, I think it should be possible.

Thanks

嗨，对话，

can you give me a response?

Thanks

嗨，对话，

you said there are pending messages, can you please give example which message?

Thanks

BenjaminDU

任何人都可以告诉我如何使用spi，同时，也可以通过ble连接？

嗨，对话，

The project I tested is dsps_device.uvprojx, the modified 3 files as attached

Thanks

Benjamin

嗨，对话，

UART is not a must, I use UART to output data in a easy way to observer the code runing during debug, but I tested my code, if I don't use the UART to out put anything, still the program can crash, also in SKD3.x, I use slave_uart and master_uart example,UART works well with SPI.

I tested SPI_flash example, and it can interact with my SPI device well.

My requirement is to read data by SPI and send the data to a peer device(eith to mobile or sps_host)

你的意思是延长睡眠模式会禁用SPI吗？SPI被停止了，也许这就是程序崩溃的原因？

Thanks

Benjamin

嗨，对话，

是的，我用的是客户板。

I use the sps_host firmware, and I can also use the mobile application , both of them can connect to the dsps_device

希望你能有一个测试我的代码，并帮助我找出哪里有问题。

Thanks

Benjamin

你好，

我测试了主动模式，它似乎工作，我会做更多的测试，以确认它。

Thanks
