Hi David, It could be that renaming is sufficient but for that I need to dive a little deeper in the PIC16F18325.
You can give it a try but I might work on it later too.

I don't want to take the risk to hang the whole main bus if those devices are not attached. And since there are two MSSP in the PIC, it's worth to use them. Rob, If it this as I described (only copy and rename the registers/variables/constants by adding a '2' as needed, if you want, I can do it myself and share it later on). I was planning to use also the i2c_level1.jal and i2c_reset_bus.jal libraries. Therefore, I think this will need 3 new (copies) files.

I could make the library for you and start this weekend. I think that it is not that much work.

This PIC has 2 MSSP modules, so this is possible. But, the I2c_hardware.jal lib does not support that: it can only reference the first module. o i have to make a copy of that lib, and rename all references to the registers of the MSSP module to access the second module ? (Ex: SSPCON2 which is an alias for SSP1CON2 should be renamed SSP2CON2 in the copy of the lib) Or is there another way ? Also note that if I want to make the buses run at different speeds (ex: one at 100 kHz, and one at 400 kHz), some global variables and constants have also to be duplicated and renamed. Any ideas welcome.... Kind regards, David -- You received this message because you are subscribed to the Google Groups "jallib" group.
