TWI glitch filtering and slew limiting
Posted: Thu May 11, 2017 8:30 am
Hi folks, it seems that AVR chips feature 50ns input glitch filtering and slew limiting of falling edges in their TWI devices. Looks like the ARM processors do not (SAM4L appears to be the only exception). With this in mind, has anyone found a buffer device (or circuit suggestion) to bring the ARM devices in line with the AVRs? Do you just need to make an AVR TWI transceiver?
