can2040 project adds software CAN bus to Raspberry Pi RP2040 microcontroller

Raspberry Pi RP2040 can2040 software CAN Bus

The can2040 project is a software CAN bus implementation for the Raspberry Pi RP2040 microcontroller that leverages programmable I/Os (PIO) to achieve reading and writing CAN 2.0B data frames at rates up to 1Mbit per second. Kevin O’Connor, the developer of the project, further explains the implementation uses only one of the two RP2040 PIO hardware blocks, so it is possible for a single Raspberry Pi RP2040 chip to have two separate CAN bus interfaces. Some processing also happens on one of the Arm Cortex-M0+ cores of the microcontroller with the processing time dependent on the amount of bus traffic, and a fully saturated CAN bus at the fastest supported rate of 1Mbit/s may use up to around 30% of that core when clocked at 125MHz, so that should still leave plenty of room for other tasks that may run on the system. I could not find any information about […]

Embedded World 2022 – June 21-23 – Virtual Schedule

Embedded World 2022

Embedded World 2020 was a lonely affair with many companies canceling attendance due to COVID-19, and Embedded World 2021 took place online only. But Embedded World is back to Nuremberg, Germany in 2022 albeit with the event moved from the traditional month of February to June 21-23. Embedded systems companies and those that service them will showcase their latest solution at their respective booths, and there will be a conference with talks and classes during the three-day event. The programme is up, so I made my own little Embedded World 2022 virtual schedule as there may be a few things to learn, even though I won’t be attending. Tuesday, June 21, 2022 10:00 – 13:00 – Rust, a Safe Language for Low-level Programming Rust is a relatively new language in the area of systems and low-level programming. Its main goals are performance, correctness, safety, and productivity. While still ~70% of […]

MIPS unveils RISC-V eVocore P8700 and I8500 multiprocessor IP cores

MIPS RISC-V eVocore

MIPS is dead, right? Well, there’s now very little done on the architecture itself, MIPS (the company) has decided to switch to RISC-V architecture, and unveiled the eVocore product lineup currently comprised of the eVocore P8700 and I8500 multiprocessor IP cores. The 64-bit cores are scalable from single-core multi-thread to a single cluster with multiple cores, and up to a multi-cluster, and target high-performance, real-time compute applications such as networking, data centers, and automotive. The eVocore P8700 comes with a 16-stage deep pipeline with multi-issue Out-of-Order (OOO) execution and multi-threading. MIPS claims it has single-threaded performance greater than what is currently available in other RISC-V CPU IP offerings, but did not provide any numbers. It will likely be used in the cloud and high-end servers as it can scale up to 64 clusters, 512 cores and 1,024 harts/threads. P8700 highlights: Multi-issue superscalar Out of Order (OOO) with Multi-threading 16-stage pipeline […]
