I am working on the SPI driver for PXA270. When entering the initialization operation in SPI_Init, dwSpiSysIntr = SYSINTR_NOP; dwHwIntr = IRQ_SSP; hSpiEvent = CreateEvent(null, false, falsE, null); if...
I found that when RS485 is reading data, sometimes a false freeze will occur. At this time, if an interrupt occurs, the program will stop at return ReadFile(g_hDEV, commRead, NumBytes, ref BytesRead, ...
