This blog captures the changes one is likely to see when switching from CYW20719-B1 to CYW20719-B2.
- One Major change for the Application developers is the different IDE requirement for CYW20719-B1 and CYW20719-B2. CYW20719-B1 requires WICED Studio for Application development while ModusToolbox is required for CYW20719-B2.
- The max tx power and configurable power levels have changed between CYW20719B1 and CYW20719-B2.
- CYW20719-B1: Max tx power = +4 dBm configurable power levels:[4, 0, -4, -8, -12, -16, -20, -24] dBm
- CYW20719-B2: Max tx power = +6 dBm configurable power levels:[6, 2, -2, -6, -10, -14, -18, -22] dBm
- Serial Peripheral Interface(SPI) driver API has been changed. Now it doesn't accept the pin configuration in the app, it needs to be defined in device configurator.
- Old API 20719-B1:
void wiced_hal_pspi_init(spi_interface_t spi,
UINT8 devRole,
UINT16 spiPinPullConfig,
UINT32 spiGpioCfg,
UINT32 clkSpeed,
SPI_ENDIAN endian,
SPI_SS_POLARITY polarity,
SPI_MODE mode,
UINT8 csPin);
- New API 20719-B2:
void wiced_hal_pspi_init( spi_interface_t spi,
UINT32 clkSpeed,
SPI_ENDIAN endian,
SPI_SS_POLARITY polarity,
SPI_MODE mode);
- I2C combined read API changed. Recieve and transmit parameters have been interchanged for uniformity across devices.
Old API 20719-B1:
UINT8 wiced_hal_i2c_combined_read(UINT8* tx_data,
UINT8 tx_data_len,
UINT8* rx_data,
UINT16 rx_data_len,
UINT8 slave);
New API 20719-B2:
uint8_t wiced_hal_i2c_combined_read(uint8_t* rx_data,
uint8_t rx_data_len,
uint8_t* tx_data,
uint16_t tx_data_len, uint8_t slave);
- Change in enum names. WICED has been appended in front of the names.
20719B1
enum CLK_SRC_SEL
{
ACLK0,
ACLK1,
};
enum CLK_SRC_FREQ_SEL
{
ACLK_FREQ_1_MHZ,
ACLK_FREQ_24_MHZ
};
20719B2
enum WICED_CLK_SRC_SEL
{
WICED_ACLK0,
WICED_ACLK1,
};
enum WICED_CLK_SRC_FREQ_SEL
{
WICED_ACLK_FREQ_1_MHZ,
WICED_ACLK_FREQ_24_MHZ
};
- Change in structure name. WICED has been appended in front of the names.
20719-B1
typedef struct{
uint32_t init_count;
uint32_t toggle_count;
} pwm_config_t;
20719-B2
typedef struct{
uint32_t init_count;
uint32_t toggle_count;
} wiced_pwm_config_t;
