BlueNRG, BlueNRG-MS stacks architecture and ACI
88
When using another external microcontroller these files should be ported/adapted for
addressing the ACI SPI communication.
In order to proper setup the ACI SPI interface, user is only requested to perform the
following steps at initialization time, on main() function:
1.
Init SPI interface by calling the following API:
SdkEvalSpiInit(SPI_MODE_EXTI);
2.
Reset the BlueNRG module by calling the following API:
BlueNRG_RST();
The user is also requested to place HCI_Isr() within the SPI_IRQ_IRQHandler() handler on
file stm32l1xx_it.c: this allows BlueNRG, BlueNRG-MS device to use the SPI IRQ pin to
notify the external microcontroller (SPI master) when it has data to be read.
