I've uploaded a Basic-X project that provides easy function code timing on the ?M-FPU V3 when it is connected to a BX-24 via SPI. An image of the project breadboard is in the group Photos section, too. The BX-24 code measures an empty function to determine timing overhead, a nominally one-millisecond delay function to establish a time scale, and the unknown code, repeatedly; the unknown co...

Hey, I'm making a synth with a bx-35 and am using a MAX3110 as the MIDI uart. And am using this schematic: http://devices.sapp.org/m icro/stamp2sx/max3110/bsmax3110big.gif as a reference (but with the Basic Stamp replaced by the BX35). I've got all the SPI communications working fine, and MIDI
