The ESP32-P4 has been announced by Espressive Systems with a RISC-V core and AI instructions. Powered by a dual-core RISC-V CPU running up to 400MHz, ESP32-P4 also supports single-precision FPU and AI extensions, thus providing all the necessary computational resources. In addition, ESP32-P4 integrates an LP-Core which can run up to 40MHz. This “big-little” architecture…

Raspberry PI silicon RP2040 has entered the embedded market with a bang, where millions of units have been sold and tens of millions are on the way. It was felt that it lacked connectivity, and Raspberry PI team have listened to the community. We now have a new version rolling out which brings effortless WiFi…

https://iotechprojects.com/sending-data-from-the-esp8266-to-mysql-directly/ Usually, we use some sort of queuing mechanism to connect two devices or processes where the reliability/availability of either end isn’t guaranteed. However, if you have a reliable connection between two devices, the queues can be skipped. The above article does exactly that. It explains how an esp8266 based board can connect to a…

I remember looking at the Intel MCS-96 datasheets in the 1990s and admiring the fact that the more expensive 16-bit controller family had the HSO/HSI (High speed output/input) capability.

Raspberry PI 2 was a great improvement over the version 1. However, we did have to attach external USB WiFi dongles to connect wirelessly. The Raspberry PI 3 offers an upgrade from 32 bit to a 64 bit ARM Cortex A-53 CPU, faster clock speed of 1.2 GHz over Raspberry PI 2’s 1GHz. But I…
