The Pins They Are A-Changin’
Some fairly major (and frankly rather overdue) changes are coming in the way that users access the GPIO pins on the Raspberry Pi. The shift will (hopefully) be fairly gradual and, for users of certain libraries, entirely invisible. However, for others they may be quite disruptive. As forewarned is forearmed, hopefully this little article may be of some use to those affected!Fri Mar 17 22:17:09 2023 - permalink -

The Amsterdam Compiler Kit
The Amsterdam Compiler Kit is a cross-platform compiler and toolchain suite that is small, portable, extremely fast, and extremely flexible. It targets a number of low-end machines including the Z80, 8086 and 80386, but there are many other code generators available. It supports several languages, including ANSI C, Pascal and Modula-2, and contains integrated runtime libraries including a libc.Fri Apr 2 23:54:59 2021 - permalink -
The maintainer, David Given states "I, dtrg, cannot honestly recommend using the ACK for production code unless as a stop-gap measure or unless the other benefits of the ACK (e.g. having a very lightweight turnkey toolchain is valuable to you) outweigh the code quality."- http://tack.sourceforge.net/
