Setup
Before using the programmer, ensure you have the necessary drivers and programming software installed on your computer.
Instalacija drajvera
The CH341A programmer typically requires a USB driver. This driver is usually not included in the package and must be downloaded from the manufacturer's website or a reliable third-party source. Install the driver before connecting the programmer to your computer.
Instalacija softvera
Dedicated programming software is required to interface with the CH341A programmer. Popular options include CH341A Programmer software (often found online) or open-source tools like IMSProg for Linux. Download and install the appropriate software for your operating system.
Povezivanje programatora
- Connect the CH341A programmer to an available USB port on your computer.
- The operating system should recognize the device after driver installation.
- Open your chosen programming software.

Uputstvo za upotrebu
This section outlines the general procedure for reading and writing data to EEPROM and BIOS chips.
General Programming Process
- Identify Chip: Determine the type and voltage of the chip you intend to program (e.g., 24 series, 25 series, SOP8, SOP16, 1.8V).
- Odaberite adapter: Choose the appropriate adapter or socket for your chip. For SOP8 chips, select the 150mil (narrow) or 200mil (wide) adapter. If the chip operates at 1.8V, use the 1.8V adapter in conjunction with the main programmer.
- Insert Chip/Connect Clip:
- For DIP chips or chips on adapters: Carefully insert the chip into the ZIF (Zero Insertion Force) socket on the CH341A programmer or the chosen adapter. Ensure correct pin orientation (Pin 1 alignment).
- For in-circuit programming with SOP8 clip: Attach the SOP8 clip to the target chip on the circuit board. Ensure all pins make good contact. Connect the clip's ribbon cable to the appropriate header on the CH341A programmer.
- Connect to Programmer: If using an adapter, plug the adapter into the ZIF socket of the CH341A programmer.
- Pokreni softver: Otvorite softver za programiranje na svom računaru.
- Detekcija čipa: In the software, use the "Detect" or "Identify" function to ensure the programmer recognizes the connected chip.
- Read/Backup: It is highly recommended to first read and save a backup of the existing data from the chip before attempting to write new data.
- Erase (if necessary): For some chips, an erase operation is required before writing new data.
- Učitaj podatke: Učitajte željeni firmver ili podatke file into the programming software.
- Write/Program: Initiate the write or program operation. Monitor the software for progress and completion.
- Potvrdite: After writing, perform a verification step to confirm that the data was written correctly.
- Prekini vezu: Safely remove the chip or clip from the programmer/circuit board.
Using the SOP8 Clip for In-Circuit Programming
The SOP8 clip allows you to program EEPROM chips directly on a circuit board without desoldering them. This simplifies the BIOS flashing process. Ensure the device powered by the chip is turned off and disconnected from power sources before attaching the clip. Carefully align the clip with the chip's pins, ensuring a firm and stable connection.

Using the 1.8V Adapter
Some modern EEPROM and BIOS chips operate at a lower voltage of 1.8V. If your target chip requires 1.8V, you must use the included 1.8V adapter. Connect the 1.8V adapter to the CH341A programmer's ZIF socket, and then insert your 1.8V chip (or its adapter) into the 1.8V adapter's socket. Failure to use the correct voltage adapter can damage the chip or programmer.

Održavanje
To ensure the longevity and proper functioning of your DollaTek CH341A Programmer Kit, follow these maintenance guidelines:
- Skladištenje: Store the programmer and its accessories in a dry, dust-free environment, away from direct sunlight and extreme temperatures.
- čišćenje: Use a soft, dry cloth to clean the programmer and adapters. Avoid using liquid cleaners or solvents.
- Pažljivo rukujte: The ZIF sockets and pin headers are delicate. Avoid applying excessive force when inserting or removing chips and adapters.
- Pregledajte veze: Periodically check the SOP8 clip and other adapters for any bent or damaged pins.
- ESD mjere opreza: Always observe Electrostatic Discharge (ESD) precautions when handling chips and the programmer to prevent damage.
Rješavanje problema
If you encounter issues while using the DollaTek CH341A Programmer Kit, refer to the following common problems and solutions:
- Programer nije otkriven:
- Ensure the CH341A driver is correctly installed.
- Pokušajte s drugim USB portom na svom računaru.
- Verify the USB cable connection.
- Chip Not Recognized by Software:
- Confirm the chip is inserted correctly into the ZIF socket or adapter, paying attention to Pin 1 orientation.
- Ensure all pins of the SOP8 clip are making good contact with the chip.
- Verify you have selected the correct chip type or family in the programming software.
- Check if the chip requires a 1.8V adapter and that it is correctly installed.
- Some chips, particularly ESMT SST class 25, may only be readable and not writable due to CH341A chip characteristics.
- Read/Write Errors:
- Ensure the chip is properly powered (if external power is required for the target circuit during in-circuit programming, though the programmer itself is USB powered).
- Check for poor contact with the SOP8 clip; sometimes one pin might not connect properly.
- Verify the integrity of the data file you are trying to write.
- Ensure the chip is not write-protected.
- The erase speed for some chips is approximately 2-3 Mbit per minute; ensure sufficient time is allowed for operations.
- SOP8 Clip Connection Issues:
- Some users have reported issues with the SOP8 clip having one pin too short, making a reliable connection difficult. Gently adjust the clip or ensure maximum pressure is applied for contact. If persistent issues occur, consider an alternative clip.
