#84811 - No No Inside ISR Responding to: ???'s previous message |
printf() inside the ISR is not the only no no. The large printf() routine most likely calls any number of other library routines from the linked on run-time library. Any of these additional routines that are not re-entrant that may be in use from the mainline will give problems when the ISR calls printf().
