You guys seen this? https://jaycarlson.net/microcontrollers/ Projects we're working on benefit from slightly more expensive microcontrollers, but interesting stuff nonetheless...

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 ...).

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
