May 21 12:05:22 HI EVREY ONE May 21 12:06:28 i am trying to set my bbb as spi slave is anybody manged to do it? May 21 12:07:15 [15:06] i am trying to set my bbb as spi slave is anybody manged to do it? May 21 12:12:17 Hi All, Had anyone experienced working with UniFlash ? May 21 12:16:56 I'm trying to have BBB as a SPI slave did any one manged to do it ?? May 21 13:19:19 naor_: maybe pmezydlo can help you on that .. May 21 13:20:11 zeekhuge, naor_: hi, what is the problem? May 21 13:20:42 naor_ is trying to implement SPI slave on BBB May 21 13:21:12 yeah I know about it May 21 13:22:31 oh ! I see that he already knows about your project. May 21 13:24:09 for now I don't have enaught time May 21 13:25:18 zeekhuge: how are you? ready for mentoring? May 21 15:18:50 naor_: McSPI supports slave mode, although you probably need PRU to service it fast enough (or DMA if you just want to blindly receive and/or transmit a stream of data) May 21 15:27:59 the A8 can service it fast enough May 21 16:31:21 I suppose it depends on the intended speed May 21 23:56:26 lol spawn a pool worker threads to receive SPI input May 21 23:58:42 that sounds like an excellent way to make your response time even slower May 21 23:59:09 (and probably get incoming data swapped around now and then) May 22 00:15:31 you'd know that structure better than me May 22 00:15:42 i don't even know how deep that buffer is or wether or not it's DMA's May 22 00:15:44 DMA'ed May 22 00:16:33 but i am assuming that read-speed is more important than write May 22 00:17:19 it all depends on what protocol is layered on top of SPI, but the big problem with most typical SPI-based protocols is that you need to respond with very very low latency since the SPI master controls the bus clock May 22 00:17:36 hence getting the response data into the fifo becomes hard-real-time May 22 00:17:57 that would make sense May 22 00:18:28 most of my imaginary uses cases for communication with the BBB involve the BBB basically acting as an endpoint for storage and eventual retrieval May 22 00:18:53 i've been obsessed with high speed ADC ever since i wokred in a semiconductor lab May 22 00:19:23 it very much depends on why the desire to have the bbb be an spi client exists in the first place May 22 00:19:28 yeh no kiddin May 22 00:19:52 i just wnat to know what the iv curve of a switching memristor looks like during its transition XD May 22 00:19:52 *spi slave May 22 00:20:36 sigh those days are over **** ENDING LOGGING AT Mon May 22 03:00:01 2017
