Platform Lattice iCE40: The iCE40 family of ultra-low power, non-volatile FPGAs has five devices with densities ranging from 384 to 7680 Look-Up Tables (LUTs). In addition to LUT-based,low-cost programmable logic, these devices feature Embedded Block RAM (EBR), Non-volatile Configuration Memory (NVCM) and Phase Locked Loops (PLLs). These features allow the devices to be used in low-cost, high-volume consumer and system applications.
[env:icezum] platform = lattice_ice40 board = icezum
You can override default IceZUM Alhambra FPGA settings per build environment using
board_*** option, where
*** is a JSON object path from
board manifest icezum.json. For example,
[env:icezum] platform = lattice_ice40 board = icezum ; change microcontroller board_build.mcu = iCE40-HX1K-TQ144 ; change MCU frequency board_build.f_cpu = 12000000L
