I'm new to PBP (but not to PIC MCU's or BASIC) - so be gentle.
I have searched the FAQ but have not seen the answers to two questions.
1) When doing an I2C write to a slave device, there is an ACK sent by the device after every byte, does PBP automatically process this and go to the FAIL label if its not received?
2) I am using a Dallas DS1307 real time clock for a Numitron clock that I am building. The datasheet for the DS1307 indicates that when the chip is transmitting the data (7 bytes) for the date and time that "The DS1307 must receive a 'not acknowledge' to end a read".
Does PBP know to do this (as well as sending the STOP) as I assume it knows to send an ACK after each byte sent by the slave?
Thanks for any help, as I said, I searched the archive and couldn't find this.
