how to use CSPIMaster together with CSPIMasterDMA about circle HOT 3 CLOSED

I understand the problem. Unfortunately the classes CSPIMaster and CSPIMasterDMA cannot be used together. I would suggest to implement your own SPI master class based on CSPIMasterDMA and to add the WriteRead() method from CSPIMaster to that class. Code using m_SpinLock and m_nCSHoldTime can be left out probably. Synchronous transfers can be done using this new WriteRead() method then.

Thanks. I will do it this way.

CSPIMasterDMA::WriteReadSync() has been added to the develop branch and will be on the master branch, when Circle 32 is ready. This method can be used now for the purpose you have described. Unfortunately there was one more patch required, compared to the things I wrote above, to get it running.
