ADuC 70xx interrupts with Keil software

Question

The Keil software shipped free with the ADuC7026 dev kit is able to program interrupts using 'void IRQ_Handler() __irq' syntax. 
 Newer versions of software will not accept this syntax. I am not a very experienced programmer, but more experienced colleagues of mine have also struggled with this without success, and since it is free software there is no recourse to Keil technical support. Has anyone else had this problem?

Hi Nic, 
 The most recent revisions of Keil uVision like version 5, require CMSIS packs. 
 The exception vectors are defined in a startup file and yes the syntax does look to have changed in newer revision but - best check with a keil source. 
 Vectors: changed to __Vectors 
 This is from a Cortex-M3 startup file supported on uVision5 
 __Vectors DCD __initial_sp ; Top of Stack DCD Reset_Handler ; Reset Handler DCD NMI_Handler ; The NMI handler DCD HardFault_Handler ; The hard fault handler DCD MemManage_Handler ; The MPU fault handler DCD BusFault_Handler ; The bus fault handler DCD UsageFault_Handler ; The usage fault handler DCD SVC_Handler ; SVCall handler DCD DebugMon_Handler ; Debug monitor handler DCD 0 ; Reserved DCD PendSV_Handler ; The PendSV handler DCD SysTick_Handler ; The SysTick handler 
 ; External Interrupts DCD WakeUp_Int_Handler ; Wake Up Timer [ 0] DCD Ext_Int0_Handler ; External Interrupt 0 [ 1] DCD Ext_Int1_Handler ; External Interrupt 1 [ 2] 
 DCD ADC0_Int_Handler ; ADC0 Interrupt [13] 
 Y our C interrupt handler functions look like this then: 
 void ADC0_Int_Handler() { } 
 
 The evaluation software for the ADuC7026 was created about 14 years ago for version 3 of uVision. 
 At this FTP link, there is an installer that if you download and run, you will get the option to install uVision3 - a version that will work with the example projects for the ADuC7026. 
 ftp://ftp.analog.com/pub/microconverter/ADuC7XXXV0.2/ 
 I think this is your fastest path to getting a working example.
