The most two common USB protocols are HID and CDC. Most of the popular open source projects which use the microchip are using the CDC for interfacing with PC. For example, the popular bus pirate, logic scrimp, ir toy are using CDC. The dangerous prototype has their open source USB stack so the bus pirate, logic scrimp, logic pirate are all using the Honken USB Stack source. Another popular open source stack is M-Stack (Free USB Stack for PIC 16F, 18F, 24F, and 32MX Microcontrollers), it has more organised source code and more detail commented. However it only has support on x series compiliers like xc8, xc16, and xc32.Last, is the microchip default USB stacks, the most common, least problem and abundant of examples. Shouldn't be troublesome if you are using microchip library and microchip compiler. In this tutorial, I am using microchip library. I like CDC over HID because it has higher transfer rate, and it appeared as serial communication. The latter feature ensures all of the terminal software can be used. My favourite terminal software is termite,it is easy to use, no installation required, auto detect and auto configure the serial port.There are other popular terminal software like tera-term, and real term. Both of these are popular among hobbies as the functions provided are vast and stable. Nevertheless, the learning curve for both software are longer. Whereas, Termite is like a software for dummy, basically no learning curve at all. To start a project USB CDC project, the

Understaning PIC ConfigurationThis second in a series of five blog posts continues exploring getting started with Microchip’s 8-bit PIC family ofmicrocontrollers by delving into basic processor memory organization and how this family of microcontrollers initialize, specifically: PIC Memory & Registers PIC Configuration Sources Revisiting MPLAB X Project Creation MCC Generated Code ExplorationPIC®, MPLAB® X, and PICkit™ 4 are trademarks of Microchip Technology Inc.All data sheet references are to Microchip document PIC18F27_47Q10-data-sheet-40002043C, © 2019 - Microchip Technology Inc, available at the time of post publishing here.PIC Memory & RegistersWhile this post does not attempt to completely explore the memory architecture of the processor family, a basic understanding of memory types and basic organization within the processor helps to understand the broad role registers play. On chip memory of the PIC18 high-end devices comes in two primaryflavors, static RAM and flash memory. Contents of flash memory persists after thepower to the microcontroller is removed; it is where application code is stored when the application is compiled and uploaded to the microcontroller via the PICkit 4 programmer /debugger. Unlike flash memory, static RAM does not persist when the power to themicrocontroller is removed; it is “working” memory whosecontent changes frequently through reads and writes as part ofprogram execution.The Data Memory Organization (heading 10.3 of section 10 Memory Organization) of the PIC18F47Q10 datasheet refers to the static RAM in the controller as data memory. This data memory isbroken up into 256-byte banks. As the PIC18 family is based on an8-bit architecture, the smallest atomic unit of memory is 8 bitswide – one byte, hence the bank consisting of 256 bytes, an amount evenly divisible by 8. This data memory element can be thought of as consisting of memoryfor two purposes, registers and application memory.The registers always occupy a specific address in data memory. Application memory contents are managed by the executingapplication. The PIC18 family has two types of 8-bitregisters, from the datasheet they are Special Function Registers(SFRs) and General-Purpose Registers (GPRs). GPRs can bethought of as scratch pads for the processor. An example ofGPR use would be when the current instruction is adding two bytes– the two operand bytes would typically be placed in GPRs and thenmoved into the ALU for the addition operation; most likely the output ofthe ALU operation would then be placed in yet another, or perhaps oneof the same GPRs. Three instructions later those same GPRscould hold two completely different values. The primary registers of interest in this post are SpecialFunction Registers – SFRs. A primary use of SFRs is control andstatus of processor peripherals. As mentioned previously, SFRs, likeall registers in the family, are 8 bits wide. The processormanaged GPIO (General Purpose Input-Output ) SFRs providefunctionality such as holding the logic value (0/1) of processorpins, determining if a particular set of pins (a port) are inputs oroutputs, or if the pins have weak pull up resistors enabled. Other SFRs configure how communication busses such as SPI and I2C operate or how a timer behaves aswell as the current count

Screen rotation, as well as puzzle rotationīy solving puzzles, you will get loot and experience. Switch day and night modes, customize color schemes Lock current puzzle state, check assumptions Auto save if you stuck you can try another puzzle and come back later Use crosses, dots and other symbols to mark cells Nonograms sorted by groups from 5x5 to 50x50 All puzzles tested by computer program and have unique solution If guessing, a single error can spread over the entire field and completely ruin the solution. Only cells that can be determined by logic should be filled. Solvers usually use a dot or a cross to mark cells they are certain are spaces. Later in the solving process, the spaces help determine where a clue (continuing block of boxes and a number in the legend) may spread. Determining which cells are to be left empty (called spaces) is as important as determining which to fill (called boxes). To solve a puzzle, one needs to determine which cells will be boxes and which will be empty. For example, a clue of "4 8 3" would mean there are sets of four, eight, and three filled squares, in that order, with at least one blank square between successive groups. The numbers are a form of discrete tomography that measures how many unbroken lines of filled-in squares there are in any given row or column.Nonograms, also known as Hanjie, Griddlers, Picross, Japanese Crosswords, Japanese Puzzles, Pic-a-Pix, "Paint by numbers" and other names, are picture logic puzzles in which cells in a grid must be colored or left blank according to numbers at the side of the grid to reveal a hidden picture.
