I2C适配器异步写:pending transactions issue

Wed, 2018-02-28 14:38--rajames

I am using the i2c adapters (in master mode) for doing asynchronous writes or reads that waits FOREVER for an OS_EVENT to be signalled from the callback.
However instead of waiting FOREVER I want to be able to set a timeout value so that it doesn't get stuck if say there's no device on the bus.

Wireless Comm Master-Slave Assignment on the fly

Under your Serial Communication example, you have two separate projects, one for a device and one for a host ( I am reading this as Slave and as Master, respectively). With the DA14580, is one able to change this relationship on the fly? Let's say I have Device A which acts as a Master and whose role it is to transmit data to Device B (Slave Device). However, there will be some circumstances where I will use a PC to download data to Device A. In this case, the PC acts as Master and Device A has now changed from Master to Slave device. How is this achieved?
