thanks for comment. there is a microcontroller on the other side and I want to have faster communication. On Monday, June 17, 2019 at 11:57:26 PM UTC+4:30, Dennis Lee Bieber wrote: > > On Mon, 17 Jun 2019 05:44:09 -0700 (PDT), > hamidkav...@gmail.com declaimed the > following: > > > > >I

thanks for comment. there is a microcontroller on the other side. the spi works fine. I send data to microcontroller and can read from it properly. but I want to have faster communication. in fact I don't need CS at all. On Tuesday, June 18, 2019 at 12:42:10 AM UTC+4:30, gra...@flex-radio.com

Hello, Nice. I just reviewed (peeked) over their site. BBBlue and me are in it to win it. Seth P.S. I am still messing w/ arducopter. I might give up on arducopter for now and try their idea. Maybe. I have my own bots but not for bots creating their own understanding of obstacle detection.

The folks at Texas A University have been working on a robot called SCUTTLE for which more and more documentation is being published and we are working through system-level tasks with them. You can find information at: https://mxet.github.io/SCUTTLE/ -- For more options, visit

Dennis: Be careful. Many/most SPI slave devices use the rising edge of the CS line, following the write activity, to load the data and make it active. So, you load it serially, but it is not transferred into the active control or output registers, until CS goes high, making it all take effect

Hi there I want to send some data to a micro controller with a beaglebone black (beagle bone is master). As shown in the picture, the delay between falling edge of cs and first rising edge of clock is too much. could you please tell me how to decrease it? the image is taken from a logic
