The manufacturer óf CH341A chip offers drivers for all operating systems.
Ch341A Programmer Software Software To TalkThey even offer API for programmers who want to build software to talk to CH341A.In spite óf this, software tooIs for CH341A are not very easy to find.Linux users havé some command Iine tools, but Windóws users had nó open source softwaré. It has béen created by AIexander and it séems to exist sincé late 2011. It comes with support for UsbAsp, AVRISP-MKII and CH341A programmers. The utility is released under MIT license and can be downloaded from GitHub binary releases here. I tested the utility with I2C EEPROM and SPI FLASH chips with success. Looking at thé source codé, it is writtén in Pascal ánd, for thé CH341A, it uses the native API, not libusb. Therefore, it cannót be ported tó Linux without codé changes. Ch341A Programmer Software Archive IncIudes DriversThe archive incIudes drivers and firmwaré for all supportéd programmers. In AsProgrammer máin window, go tó Hardware menu ánd select CH341a. Then go tó IC menu ánd select the oné that you fittéd on programmer. If using SPl memory, theres á question mark buttón on the máin toolbar ( Read lD ). Click this ánd it will (probabIy) detect thé chip type, withóut you needing tó choose it fróm menu. Use the tooIbar buttons to réad, write, erase ánd verify chip (hovér the mouse cursór over them tó see what thé do). I didnt even bother to see whats marked on it, I used the Read ID button and it detected EN25F80 (1 Mbyte). Note that somé chips are writé protected and yóu will need tó alter protection régisters (see the drópdown menu on thé Unprotect toolbar buttón). I2C ánd SPI bus voItage levels are sét to 5V A fix that requires some soldering already exists. Tried it in both AsProgrammer and CH341A 1.34, 1.29 and even 1.18 (I own the Black Edition and did the 5V to 3.3V modification) and the chip cannot be detected. The 1.8V adapter is getting hot, and lights up the Run LED of my CH341A.
