Hi guys,
i'm a student of University of Genoa (Italy). I'm new on your website an i have already found some important information for my research. You ar very cool and professional. Now i write here because i want to try to calculate the Interrupt Latenc for freeRTOS using an ARM LPC23xx.
The idea that i have is that: i want to generate an interrupt from extern and to misure the time tha will be between when i generate the interrupt and the time when the firs instruction af the interrupt routine will be executed. The misuremen should be made by inserting two probes of an oscilloscope in the interrup line and in the output. Then the time that should be between the two puls will be the Interrupt Latency.
THE PROBLEM CORE IS THE CODE!!!
So, i ask you if someone has ever wrote a code to make this or has eve made a code to calculate Interrupt Latency in some way.
Best Reguards to you all. Thanks. Davide.
