Rob, Here attached the files to control a second I2C bus for PIC'w with 2 MSSP modules (ex: PIC16F18325 which I'm gonna use in my next project) I did not add a control to see if the PIC has a second MSSP at compile time, because it was not controlled for PIC with one MSSP either....
Nothing is tested, but if it compiles, it should work, because what I did was only "Search and replace". i did not touch the logic Feel free to adapt as you wish Le mercredi 26 mars 2025 à 16:23:18 UTC+1, David VB a écrit : > Hi, > > I will use a PIC16F18325 to control (as master) TWO separate I2C Buses. > 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 ?
