I like MISO and MOSI instead because they are super-explicit and spell everything out for you. --- End quote --- Anyone considered that SPI doesn't have to mean 'master/slave'? Sometimes it is just peer-to-peer data, spat out when it's available rather than triggered by one end or the other. Master/slave would be appropriate for multidrop, but otherwise who is in control and who is being controlled is a purely software thing, so not really appropriate at the hardware level. Indeed, if it were a software stack there would be too much cohesion between the two levels if you did that. --- End quote --- wrong, so the chip in question can generate it's own clock and has chip select pins to pick who it is sending data to? SPI is master/slave, only one device can control. Yes it is possible to have a multi-master situation but I think that is very rare and probably only happens between micro controllers. Peripheral chips never really have the ability to control the bus. SPI is so ubiquitous because it makes life so easy, a single clock, MISO and MOSI and you can talk to as many other chips as you have pins to enable them with with no buggering about with addresses like other protocols require where you often can't have 2 or more of the same chip on the bus and also have to hope that different chips don't have the same address. |

Just signed up to post this. So angry. Long time lurker. https://www.oshwa.org/2020/06/29/a-resolution-to-redefine-spi-pin-names/#comment-499399 Can a few others leave some sensible comments here please. This is going too far in general. I'm positive that none of the people who post in this forum are 'white supremacists' as this article suggests. I, throughout my career have met EE of many races and colours and none of them understand what the hell is going on, none of them have any issue with the terms MASTER and SLAVE, these are word that perfectly describe a FUNCTION. The words do not belong to one race and while I completely disagree with racism I too disagree with being told what words I do and do not have the right to use. Rob, |

Slavery isn’t exclusive to people of color, it permeated society for millions of years, and literally nobody else has a problem with using those words for hardware. The sorry state of society we’re in that we must need to create our own problems when we don’t want to deal with real problems. How about addressing the rampant gangs that destroyed our cities, or the militant takeover of Seattle. Nope, we’re going to fix the problem by frying electronic devices because no one knows which way they need to be connected. What’s next, are you going to petition BDSM clubs to stop using words master and slave. --- End quote --- The blogs promoting the "SPI resolution" are censoring people with opposing opinions, somewhat ironic. --- End quote --- Yeah, thanks, take note guys: --- Quote ---Endorsements Individuals and companies welcome (Email info@oshwa.org to be added to the list below) Adam Benzion, Hackster.io bunnie, bunniestudios Glenn Samala, Sparkfun Harris Kenny, OSHdata Jason Huggins, Tapster Robotics Jonathan Georgino, Binho LLC Joshua Lifton, Crowd Supply Libi Striegl, Media Archaeology Lab Limor Fried, Adafruit Industries Matthias Tarasiewicz, RIAT Institute Nathan Seidle, SparkFun Electronics Phil Torrone, Adafruit Industries Shawn Hymel, Hello Blink Show Steven Abadie, OSHdata Tod Kurt, ThingM Tom Igoe, NYU ITP Joel Murphy, Pulse Sensor Yury Gitman, Pulse Sensor --- End quote --- |

Comments already disabled, I guess telling people what they can and cannot say is easier if you also delete all the historical words you disagree with. |
