Interesting review of $1 microcontrollers

Projects we're working on benefit from slightly more expensive microcontrollers, but
interesting stuff nonetheless...

but interesting stuff nonetheless... A well presented and through review. Would like to mention that some of the FPGA soft core processors have an incremental cost under $1 and have full tool chains: ZPU and some versions of RISC-V. Many of the legacy processors not mentioned by Jay Carlson also qualify (soft-core version with under 1K LUT count: 6502 ...).

version with under 1K LUT count: 6502 ...). If you don't mind programming in Forth, there are stack soft processors that scrape the bottom of the cost barrel. They reach a LUT usage level where you can use several of them assigning separate tasks to each one rather than worrying with multitasking. -- Rick C Viewed the eclipse at Wintercrest Farms, on the centerline of totality since 1998
