But, first of all, let's have a look at the hardware. Also, some source codes are available from manufacturer. The problem is that this device comes as-is, without any documentation or software.ĭrivers are available from manufacturer's website (but the site is written in Chinese). A popular device is the so-called ' that you can buy for 2 to 5 USD. The IC is somehow limited in this configuration, because the programmer makes use only of the SPI and I2C interface. The chip is manufactured by Chinese company CH341A is used by some cheap memory programmers. ![]() Spi Serial Flash Programming Schematic DiagramĬH341A is an USB interface chip that can emulate UART communication, standard parallel port interface, parallel communication and synchronous serial (I2C, SPI).
