Sujet : RP2040 / Pico shared ram? De : jl (at) *nospam* glen--canyon.com (john larkin) Groupes :comp.sys.raspberry-pi Date : 03. Oct 2024, 23:32:17 Autres entêtes Organisation : A noiseless patient Spider Message-ID :<kh6ufjdf1g6d6sp2q279mtp08lusibf8v4@4ax.com> User-Agent : ForteAgent/8.00.32.1272
Given an RP2040 CPU with two ARM processors (we call them Alice and Bob), how can they talk to one another?
We hate FIFOs. Is it possible for them to share a block of the SRAM? It would be cool if the two programs could both declare a struct and both be able to access it simultaneously. We's manage the access details ourselves, who writes to what variables.
