EEPROM CH341A programmer – Read and write data to chip on Linux
CMOS CH341A is a dedicated IC for serial EEPROM programming. It integrates USB to RS232 UART interface, I 2 C Bus, SPI Bus, and other serial Bus. The chip itself is low-cost, small size, and it supports EEPROM up to 24Cxx series. It’s widely used by electronic hobbyists and technicians.
Programming using EEPROM CH341A
Programming using EEPROM CH341A is possible on Linux platform. There are two ways to do it:
- Using a command line tool – Programming with a command line tool requires that the device is connected to the computer via a USB interface and that the required software is installed. Once the device is connected, the Linux command “lsusb” can be used to find the device where “lsusb” lists all USB devices connected to the computer.
- Using a graphical user interface – Programming with a graphical user interface involves selecting the type of EEPROM, selecting the required parameters and entering the command to be sent. The graphical user interface supports multiple types of protocols, such as I2C, SPI, and USB. Additionally, it supports auto-detection of the EEPROM type and an easy addressing system.
Read and write data to chip with EEPROM CH341A
Read and write data to chip with EEPROM CH341A is possible with Linux. To read the data from chip, the Linux command “dd” can be used which reads in a specified number of bytes from the given address. Additionally, the “dd” command can be used to write the data back to the device after programming.
EEPROM CH341A is a cheap, easy to use and widely used programmer for serial EEPROMs. It can be used on Linux platform with the help of command line tool or a graphical user interface. The “dd” command can be used to read and write data to the chip which makes programming with EEPROM CH341A significantly easier.
