Microchip PIC32MZ-W1 is a 32-bit MIPS WiFi MCU with 60+ GPIO, USB, CAN Bus, Ethernet, and more

PIC32MZ W1 and WFI32 2.0 Curiosity Board

Microchip recently released the PIC32MZ-W1 wireless MCU along with 20 other WiFi parts, including WiFi MCUs, link controllers, network controllers, and plug-and-play modules. Among them, the PIC32MZ-W1 wireless MCU is the most interesting because of its 32-bit MIPS microAptiv M-class core running at up to 200MHz, advanced hardware security features, and integrated Microchip Trust Platform for secure cloud authentication. Over the years ESP32 MCUs have become the go-to choice for wireless applications. Still, one problem we always have with ESP32 SoCs is their limited GPIO option due to their strapped-out pin structures. But this new MCU has over 60 GPIO pins to work with along with Ethernet MAC, USB, CAN Bus, CANFD, SPI, I2C, SQI, UART, ADC, JTAG, and more. PIC32MZ-W1 wireless MCU specifications MCU MIPS32 M-Class core clocked at 200 MHz 16KB I-Cache, 16KB D-Cache microMIPS mode (up to 35% smaller code size) DSP extensions (4x 64-bit accumulators, single-cycle […]

DALI2 expansion module for ESP32-C6-Pico and ESP32-S3-Pico boards facilitates Smart Lighting integration

Waveshare has recently launched the Pico-DALI2 expansion module for ESP32-Pico series boards designed to enable DALI communication for customized control of multiple lighting groups. It is compatible with development boards such as the ESP32-C6-Pico and ESP32-S3-Pico and includes a DALI communication screw terminal for connecting external DALI devices. DALI (Digital Addressable Lighting Interface) is a standardized protocol used for lighting control in building automation systems. The latest version of the DALI2 protocol is better than the old one in that it offers enhanced interoperability, additional features like multi-master configurations, and better energy management capabilities. DALI2 devices can communicate bidirectionally, meaning controllers can send commands and also receive status feedback from lighting devices, allowing for more complex automation and diagnostics. We can get more information about DALI from Wikipedia. We have previously seen the uses of DALI in Texas Instruments MSPM0 Arm Cortex-M0+ microcontrollers as an interface and in Acme CM3-Home […]
