Willar SP200Se ProgrammerI recently grabbed one SP200SE device programmer from an online vendor and was amazed to explore the rich features of this module with such a low price tag. This module costs less than Rs.

The following are code examples for showing how to use serial.Serial.They are from open source Python projects. You can vote up the examples you like or vote down the ones you don't like. About the Programmer This is a Simple com port based Microchip PIC microcontroller Programmer,This Programmer is based on JDM programmer.The entire programmer is built around commonly available components Features. Does not support the usb to serial converter. Works with most of PIC mcu. Works with 18F2550 and other 18F series mcu.
800 and supports some of the most popular family of MCUs like 8051, 8052, MegaAVR and TinyAVR. All in all it can program 200+ different device including MCUs and Serial EEPROM. After exploring the programmer for a while, I decided to write a Know-How article to use this device programmer.Overall it’s simple to use with the WLPro programmer software. But there a few tricks that one must learn to use this device programmer efficiently.
Unfortunately WLPro software is available only for Window based systems. Let’s do a step by step run through of using SP200SE Device Programmer on Windows based PC. Features. Easy to Use.
USB Interface to PC. Easy to use and Intuitive Software GUI. Supports 8051/52/MegaAVR/TinyAVR/ EEPROM. ZIF Socket.
Small size. Low CostStep – 1 Install USB-TTL Chip Drivers on your ComputerSP200SE has this chip called CH340T to have USB interface. CH340T converts USB data into TTL serial data stream. One must install CH340T drivers to use SP200SE.Install these drivers and make sure after installing the driver you have a COM Port listed on your device manager. May be something like COM13, COM2 etc. If it is not listed in device manager try restarting your operating system.If your COM Port number is in 2 digits i.e.
10, 12, 13.your SP200SE will not work as it needs a single digit name of com port number. So its time to change your com port number to single digit. Step – 2 Convert COM PORT number to Single Digit, If not already in single digit. Choose SP200S Enhanced Programmer, Green DOT must be ON to use device Programmer Step – 4 Choose Device and Program/ Verify/ Read/ Protect etc.SP200SE is super easy to use and very useful tool at a very low cost. A Must have for all serious hobbyists and embedded system designers.For any queries related to SP200SE Device Programmer, use the comment section below. I hope this article helps you to learn something new.This entry was posted in, and tagged, on. Post navigation.

My question is regarding the exact timing of inserting the device into ZIF socket, during the sequence of operations (steps) required during programming.A typical sequence is detailed below, which is vaguely described or IMPLIED in many online manuals:-Infact none of the manuals are of good readable english, let alone professional!A) INSERT the Microcontroller Device into the ZIF socket of SP200S.B) Connect the SP200S-Unit to a PC, using USB-cable, there by powering the programmer.Blue or Green Power-LED comes on.C) Run “WLPRO” software in PC. It detects the programmer-unit (Green Online Mode).D) Now “Select Device” to be programmed: SST89E516RD.E) Click on “Program”-button & Provide bin/hex file. The RED programming LED comes ON.Now my question is regarding Step-A (Inserting micro into ZIF socket).
Is it at the correct position/timing?Is’nt the Correct & Safe position/timing between Steps- D & E?My concern is that the microcontroller may get damaged, if inserted earlier before plugging into USB. Since some times randomly I see the RED-LED coming on while plugging programmer into USB itself. In such case the signals & power at ZIF-socket may not be defined properly for that particular micro, resulting in it getting damaged.Can some expert comment on this & share their experience?regards.
