Steps for Developing NRF8001 driver for Arm-M3 Lpc1758

[sidd]

Hi I am trying to write a driver for the nrf8001 BLE and interface it with LPC1758 Arm M3. I am a beginner in this field and I am not exactly sure, if I am following the correct steps. 

My understanding is- 

1. To get out of the unkown state which is mentioned on page 80 of the product specification, I need to give a reset(active low). In order to do that, I give a low signal to the BLE RST pin. 

2. According to the various posts and also by the diagram on page 82, I will receive a DeviceStartedEvent after the reset and before I send my setUp data. However, I am not receiving anything until and unless I send some data to the nrf8001. 

I am sure that somewhere, I am missing something or my understanding is wrong. I would really appreciate, if anyone has worked with nrf8001 on Arm-m3 and can help me develop the driver for it. 

Best

Sid.

There is a driver that is for the STM32 F series based on the Maple port for STM32.

You can look for the links in this case.

Hi David, 

Can you validate my understanding in the post above. I believe that that MISO line will receive a Device Started Event, when I pull the Reset line for minimum of 200 ns and in result the nrf8001 will pull the Rdy line. I can send the logic screen, if you require it,
