Hi!!
I'm adding spi functionality to S132 and SDK 14.0.0 ble_app_uart now.
The communication which added the function of UART to SPI and the sample code of ble_app_uart are successful.
for (;;)
{
if(0 == nrf_gpio_pin_read(30)){
SPITxDummy(0x00); //Dummy_Data LOFFSTAT
SPITxDummy(0x00); //Dummy_Data LOFFSTAT
SPITxDummy1(0x00); //Dummy_Data CH1
SPITxDummy(0x00); //Dummy_Data CH2
SPITxDummy(0x00); //Dummy_Data CH2
}
power_manage();
}
code1：External interrupt handling
void SPITxDummy1(unsigned char Data)
{
//uint8_t * p_data;
nrf_gpio_pin_clear(22); //CS pin low
static uint8_t m_rx_buf[2];
m_rx_buf[0] = 0;
nrf_drv_spi_transfer(&spi, &Data, 1, m_rx_buf, 2);
// p_data = *m_rx_buf;
m_rx_buf[0] = *m_rx_buf;
nrf_delay_us(100);
//app_uart_put(m_rx_buf[0]);
}
code2：ExternalDummy data output
I would like to output five dummy data when the pin 30 goes down, I want to transmit the data wirelessly and see it on the smartphone.
I have 2 questions.
①When the 30th pin goes down, should 5 dummy data output instructions be placed in the for statement here?
②I want to receive data with Dummy 1 and transfer the data over wireless,I want to receive data with Dummy 1, want to transfer data by radio, but how do I store the data received by SPI in p_data on nus_data_handler??
I sincerely wish to achieve this project from the bottom of my heart.
If you have something to know, please tell me!!!
thank you in advanced!!!
