HAL I2C Routines

RAyWB

Hi,just a question regarding the I2C Routines in HAL :I s there a reason why Arduinos Wire Routines are not used?and would it make sense from your side to Change Hal to the wire routines?
Spent a lot of time a year ago to fix the routines for DUE and they work well on MCP23017 and PCA 8574.at the Moment I try to get PCA9685 running but for unknown reason i can´t read back from it.Component itself is OK as it´s working with Wire library.

Good question. This makes it easier to stop using arduino. Maybe also a speed issue, not that I think it would be a issue on due. Or wire just did not exists when we started the due port. I can't say as initaial due port is not from me.

Is wire address number the same? On AVR they differ by factor 2.

adressing is ok , so i know that from work with the mcp23017.still fighting with datasheet of pca9685, seems to need Special initialisation.so as i just want to add some external pwm´s i think i´ll Switch over to TLC5947 and Software spi as it´s faster and i have some spare Pins to handle that.Might be interesting for spindle control and laserdriver if it works.so in that case there is no Need for timers ;-)
