SPI example for CYW20706

[AnjanaM_61]

This application demonstrates how to use SPI driver interface on CYW20706 to send and receive bytes or a stream of bytes over the SPI.

Hardware connections on CYW20706 EVAL:

For SPI Slave use the below pins :

•   CS   - P26
• MOSI - P27
• MISO - P25
• CLK  - P36

For SPI Master use the below pins :

•   CS   - P26
• MOSI - P0
• MISO - P25
• CLK  - P36

Test Procedure:

• Program 1 kit with the spi_master app and another kit with spi_slave app (attached the project).
• Connect the SPI lines and ground on the 2 kits.
• Power on the kits. You can see the logs through PUART
• Reset the SPI master first and then SPI slave.

有几个问题请教一下：

1.您使用的WICED是什么版本？我有很多API与您的不相同

2.您SPI Master Demo中#define MASTER1_P36_CLK_P00_MOSI_P25_MISO  0x00240019  

“0x00240019 ”是如何得到的？

3..您SPI Master Demo中使用的GPIO为P36\P00\P25\P26吗？？与您Blog中介绍的不符？？请问实际使用的GPIO为哪个？

Hi,

1. I am using WICED SDK 6.2

2. available pin combinations are in spiffydriver.h

   The value can be find out as below

MASTER -  0x[00][hex of clock pin (eg: 24(hex of 36) for P36 )][hex of mosi pin][hex of miso pin]

SLAVE1_P36_CS_P24_CLK_P27_MOSI_P25_MISO 0x[hex of CS pin number][hex of clock pin ][hex of mosi pin][hex of miso pin]

3. Couldn't able to understand your query.

Thanks,
Anjana

Hi Anjana，

I am using WICED SDK 6.2，copy your code and config pins follow you。

But logs through PUART  always are [Rx]Sent start byte。

Follow code，it can't pass if(ACK_ID == rec_byte[0])，do you have some suggestion to check it?

Thanks,

Leo

Can you please try by P33 switch position in OFF on PUART SELECT SW5 ?

Please try reset both devices (first master and then slave) and try.

3.The Hal_spi_master.c is    #define MASTER1_P36_CLK_P00_MOSI_P25_MISO  0x00240019.but Your introduction

For SPI Master use the below pins :

•   CS   - P26
• MOSI - P27
• MISO - P25
• CLK  - P36

Hi,

Sorry , it was a mistake from my side. Modified the intro.

Sorry for the inconvenience.
