The reason for this question is that the data sheet for the User Module says, in the example C code:
The same code in C is as follows. Note that the interrupt routine must be written in assembly.
I note however that the User Module comes with an example project, which uses an ISR written in C, so I am wondering it the statement in the User Module data sheet is simply incorrect.
My datasheet is version 2.6, Designer is version 5.4.
I note also that the Compiler Guide says:
To associate the interrupt handler with an interrupt, add ljmp _name at the interrupt vector in the boot.tpl file.
When I look in the boot.tpl file, it says:
org 38h ;PSoC Block DCC12 Interrupt Vector
`@INTERRUPT_14`
reti
so I think the compiler guide is asking me to change this so that it reads:
org 38h ;PSoC Block DCC12 Interrupt Vector
ljmp _MyTimer16Interrupt
reti
Would that be correct? If I do this, it builds but with a warning "old-style function definition for `MyTimer16Interrupt'"
and it warns me that 'boot.asm' has been modified outside of the editor, do I want to reload it. (Words to that effect.)
I can't help thinking that, despite following the instructions, I'm not doing whatever it needs to make it entirely happy. Any suggestions?
