I have a question about Cygnal’s C8051F320 USB microcontroller and SDCC/Keil compilers. When I look at the USB_INT example code
that comes with the development board, the hex file is almost 16KB. Does this
imply that the memory of the microcontroller is almost completely full with the
USB code and that there is no space left for any other code? The really strange
thing is that the Keil compiler that comes with the
kit is limited to 4KB, but the hex file is 15KB… I must be missing
something here? If the memory is indeed full already, what are the options for
expanding the memory or reducing program size? The hex file resulting when
compiling with SDCC is pretty much the same size (the USB_INT SDCC port by
Thanks in advance,
PS: sorry if this is a little off-topic.
