Hi All,

I am working on a legacy product which requires me to compile and flash a code to ST7Flite29 controller.
I am using Ride7 IDE and have configured it for ST7Flite but if i compile, the RCSTM8 compiler runs automatically and throws error of Invalid '@' Character error for the file where ST7 registers are defined.
Below is the error message - 

** ERROR P002 IN LINE 137 OF hal/ST7Lib/devices/st7flite2/../../peripherals/../devices/st7flite2/st7flite2_reg.h : Invalid '@' character
*** ERROR P002 IN LINE 138 OF hal/ST7Lib/devices/st7flite2/../../peripherals/../devices/st7flite2/st7flite2_reg.h : Invalid '@' character
RCSTM8 COMPILATION COMPLETE. 0 WARNING, 2 ERRORS

I tried to check in RCST7.exe which also exists in the same place as RCSTM8 but the RCST7 is just a stub file which internally directs to STM8 compiler.
How do i get it to run for RCST7. Do i need to install again.
Can you please provide me a link to download the Raisonance ST7 Compiler if the compiler installation was an issue
