Member Function Documentation
| void close | ( | ) |
Close SPI - disables IRQ and set received buffer to 0.
- Parameters:
-
none
- Returns:
- none
Definition at line 81 of file cc3000_spi.cpp.
| uint32_t first_write | ( | uint8_t * | buffer, |
| uint16_t | length | ||
| ) |
First SPI write after powerup (delay needed between SPI header and body)
- Parameters:
-
buffer pointer to write buffer length buffer length
- Returns:
- 0
Definition at line 92 of file cc3000_spi.cpp.
| void open | ( | ) |
| uint32_t read_data_cont | ( | ) |
Process the received SPI Header and in accordance with it - continue reading the packet.
- Parameters:
-
None
- Returns:
- 0
Definition at line 174 of file cc3000_spi.cpp.
| void read_synchronous | ( | uint8_t * | data, |
| uint16_t | size | ||
| ) |
Low level SPI read.
- Parameters:
-
data pointer to data buffer size number of bytes
- Returns:
- none
Definition at line 168 of file cc3000_spi.cpp.
| void set_wlan_en | ( | uint8_t | value ) |
Enable/Disable the WLAN module.
- Parameters:
-
value 1 : Enable 0 : Disable
- Returns:
- None
Definition at line 214 of file cc3000_spi.cpp.
| void wlan_irq_disable | ( | ) |
| void wlan_irq_enable | ( | ) |
| uint32_t wlan_irq_read | ( | ) |
Get WLAN interrupt status.
- Parameters:
-
None
- Returns:
- 0 : No interrupt occured 1 : Interrupt occured
Definition at line 77 of file cc3000_spi.cpp.
| void WLAN_IRQHandler | ( | ) |
SPI interrupt Handler.
The external WLAN device asserts the IRQ line when data is ready.
The host CPU needs to acknowledges the IRQ by asserting CS.
- Parameters:
-
none
- Returns:
- none
Definition at line 222 of file cc3000_spi.cpp.
| uint32_t write | ( | uint8_t * | buffer, |
| uint16_t | length | ||
| ) |

- Parameters:
-
buffer pointer to write buffer length buffer length
- Returns:
- 0
Definition at line 109 of file cc3000_spi.cpp.
| void write_synchronous | ( | uint8_t * | data, |
| uint16_t | size | ||
| ) |
Low level SPI write.
- Parameters:
-
data pointer to data buffer size number of bytes
- Returns:
- none
Definition at line 161 of file cc3000_spi.cpp.
