I've never used such a scheme. I usually either use polling or interrupts, but not polling inside interrupts. It should work ok though.
Btw. When I need more transfer speed from a (virtual) comport I use an FTDI FT245. It has a parallel interface, handshake lines and internal buffers. Just send the packet on the PC to the "comport" and when the mcu has realized it needs attention, the buffer is probably filled up with many bytes already. Then I get them out as fast as the mcu can and as many as possible. I get over 900kBytes/sec which is near USB fullspeed maximum of 12Mbit/sec. The typical application is booting an FPGA. |
