I've been wanting something for longer reads for a while now so I whipped something up. This will allow you to point to a struct that contains all of the data (addresses, length, and an array to read to / write from): https://github.com/boarchuz/HULP/blob/41a13b672cbb279ba8a092501c370dc747e20d12/include/hulp_i2cbb.h#L287-L454
I haven't tweaked any of the timings yet but most I2C slaves are pretty tolerant in my experience so should be fine. Let me know how you go.
That's fine, thank you for replying to my request. I just adjusted at row 387 with I_GPIO_READ(sda_gpio) and added initialization of the .unused parts in the struct and everything was getting work as expected.
A slightly optimised version just pushed to master. I've decided not to fix timings, it's a lot of faffing about for something that's probably fine and not a high priority.
Some sensors like the ADS-111x DO require 16-bit readouts. Could you please add a macro for 16 bit write?
