OneTransistor - Good website if you are looking for electronics ideas and many Maker topics. Printer Port - The device can emulate a EPP Parallel Port over USB to be able to connect to older printers. Parallel Interface - This interface can be used to talk to parallel memory Bus with all the required control signals. Synchronous Serial - I2C and SPI - The chip has 3 chip select pins and Multi-mode support for SPI protocol. It can also be used for RS-485 since it has automatic driver control pin also available. UART - The chip can be used as a USB to UART converter. There are 4 major items that become clear from the enclosed Datasheet(English) This is versatile USB to multi-protocol converter chip. Please note that this repository is a Coagulation of know-how from different sources. What's the best option, and why? I only really need to reprogram motherboard (desktop/laptop) and maybe GPU BIOS at the moment.Documents and Software Related to the famous CH341a used in I2C/SPI Flash Programmers also called as BIOS Programmers I never used a CH341A - are they as easy to use as the TL866CS?Ī third option is to get a 1.8V adapter for the TL866CS which is even cheaper but I remember seeing somewhere that they don't work/are useless? Though I don't know why. I also have the option to buy just the programmer for €46.70, if I could get the 1.8V adapter separately and use the other eprom adapters from my TL866 CSīut another option seems to be to buy the CH341A for much less money €10.30 which says it does 1.8V and 24/25 series eproms These come with various attachments and the kit including a 1.8V adapter is either €62 with 12 adapters or €68 with 1 7adapters. I could splash the cash and buy a V11.71 TL866II. However for the first time I have come across a 1.8V Eprom and my programmer will not do 1.8V 
I have a TL866 CS Eprom programmer and up until now it did everything I needed to do
