Cool! The Bus::I2C:: namespace seems safe. Short, unambiguous, unlikely to have a legitimate claim from software. Under that you could put chip names like Bus::I2C::DS1307 [1] but I suspect software will fit better by function like Bus::I2C::EEPROM [2] since families of chips will naturally share code. The CPAN search for just I2C shows a few things, https://metacpan.org/release/i2c (i2c_{ser,lpt}) https://metacpan.org/pod/HiPi (various under HiPi::*) https://metacpan.org/pod/Device::LPS331AP https://metacpan.org/pod/Device::Gyroscope::L3GD20 https://metacpan.org/pod/Device::SMBus https://metacpan.org/pod/Device::WebIO::Device::I2CUser so it's probably too late to converge on one perfect naming scheme anyway. > Ultimately, it'd be cool to end up with lots of hardware chip > drivers on CPAN that can talk to all kinds of hardware, via whatever > mechanism people use to physically attach it. > > But lets start with the name... I don't see a way to avoid the usual problem with someone releasing Bus::I2C::EEPROM::Lite and Bus::I2C::EEPROM::Tiny after the first come module gets bloated out with obsolete parts. -- Matthew [1] http://www.rapidonline.com/Electronic-Components/Maxim-DS1307-Timekeeper-with-BCD-Real-Time-Clock-82-0567 [2] http://www.rapidonline.com/Electronic-Components/ST-M24C64-WMN6P-EEPROM-64k-SO-8-73-3636 http://www.rapidonline.com/EEPROMs -- The Wellcome Trust Sanger Institute is operated by Genome Research Limited, a charity registered in England with number 1021457 and a company registered in England with number 2742969, whose registered office is 215 Euston Road, London, NW1 2BE.
