The Atomthreads port uses Timer 1 to drive the system tick. If you wish to use some other timer then you may do so by modifying atomport.c. +Note that the build scripts make no assumptions about the RAM and program +space available on your platform, partly because you may have external RAM +over and above the ATmega device's internal SRAM. You must, therefore, +ensure that you have sufficient RAM and program space available for the +applications that you build. This information can be obtained by passing +the application ELF filename to the avr-size utility. + ---------------------------------------------------------------------------
