Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

MSSP Driver Melody Module

Overview

The Master Synchronous Serial Port (MSSP) module is a serial interface useful for communicating with other peripheral or microcontroller devices. These peripheral devices may be serial EEPROMs, shift registers, display drivers, A/D converters, etc. The MSSP module can operate in one of two modes:

  • Serial Peripheral Interface (SPI)
  • Inter-Integrated Circuit (I2C)

Features

The SPI and I2C interface supports the following operating modes

  • Host mode
  • Client mode

The driver operation can be configured as

  • Polling
  • Interrupt

Changelog

All notable changes to this project will be documented in this file.

[7.0.3] - 2024-12-18

Bug Fixes

  • M8PD-12295 :- Updated I2Cx_IsBusy API in MSSP host driver to remove S bit check in SSP1STAT register
  • M8PD-7589 :- Modified the client driver error handler to clear the SSPOV bit if it is set by hardware, preventing the bus from locking up
  • M8PD-5173 :- Corrected the wrongly set read-only SSPxSTAT bit during I2C client operations, with the default set to zero

[7.0.2] - 2024-09-27

Bug Fixes

  • M8PD-10703 :- Unit test stage on CICD pipeline and locally passed when the coverage for the module files was lesser than the threshold
  • M8PD-9373 :- Included stddef.h header in the interface files of the I2C/TWI Host and client for successful compilation
  • M8PD-9323 :- Fixed the PIC MSSP driver to check for ACKTIM bit after an address match by the client
  • M8PD-8902 :- Fixed I2C drivers to avoid incorrect occurrence of TX_READY state prior to the ACK reception for the address match
  • M8PD-8844 :- Fixed the I2C client to check for ACKSTAT bit for address match instead of checking ACKDT
  • M8PD-8843 :- Fixed I2C drivers to enable clock stretching for ack, address or data reception
  • M8PD-6136 :- PIC16 I2C Client Address match event occurs after the ACK/NAK has already occurred
  • M8PD-5191 :- Fixed the I2C address mask for PIC18F devices to be set to default POR of "7F" to avoid I2C slave malfunctioning with multiple devices
  • M8PD-5088 :- Fixed driver to avoid generating continuous I2C NAK interrupts after setting PEN for PIC16F13145 device

New Features and Improvements

  • M8PD-7530 :- Fixed MISRA violations for I2C/TWI firmware

[7.0.1] - 2023-11-30

Bug Fixes

  • M8PD-3078 :- Access SPI only through SPI_Host and SPI_Client Drivers
