 | | Time available during 1 kHz system interrupt? —Greg Starr

| | | Does anyone know the approximate amount of time available for user assembler programs which "add on" to the existing 1 kHz HB interrupt? Another way of stating that is...how much time is used by the 1kHz HB ISR code? --greg ***...*** * Greg Starr, (...) (25 years ago, 1-Nov-99, to lugnet.robotics.handyboard)

| | | | Hi Greg, It all depends. Various features of the HB can be turned on and off to change the amount of work done in the main ISR. By default the code uses 300ms to execute. The file lib_hb.c provides the following: /***...***/ /*** System Interrupt (...) (25 years ago, 2-Nov-99, to lugnet.robotics.handyboard)
