Webb16 juni 2011 · PIC24F UART RX interrupt never called Hi, I have been trying to get simple UART RS-232 communication going with a PIC24F16KA102 PIM and an Explorer16 board. The PIC24 transmits fine, but I cannot get the receive interrupt to actually get called - even though a scope shows valid TTL on the PIC's RX pin. WebbThis example project demonstrates how to configure and use an internal PIC24F timer using an interrupt. You will be shown how to configure a PIC24 timer to generate an overflow interrupt every half-second. You will write a simple C function to toggle an LED.

WebbSince we need to use this value in switch_threads, we load it into register edx: .globl thread_stack_ofs mov thread_stack_ofs, %edx. Next, switch.h defines SWITCH_CUR and SWITCH_NEXT as the offset of cur and next within the stack frame (20 and 24; see how this matches with what is shown in the earlier figure). WebbThis feature is called the Interrupt Stack Table (IST). There can be up to 7 IST entries per CPU. The IST code is an index into the Task State Segment (TSS). The IST entries in the TSS point to dedicated stacks; each stack can be a different size. An IST is selected by a non-zero value in the IST field of an interrupt-gate descriptor.
