AVR USB ISP Programmer Pinout Explanation
The AVR USB ISP Programmer is a popular device used to program and debug AVR microcontrollers. It has a 10-pin interface that connects to the target AVR device. Here's a detailed explanation of each pin and how to connect them:
Pin 1: VCC (Target Voltage)
Function: Provides power to the target AVR device.
Connection: Connect to the target AVR device's VCC pin.
Pin 2: GND (Ground)
Function: Provides a common ground reference between the programmer and the target AVR device.
Connection: Connect to the target AVR device's GND pin.
Pin 3: MOSI (Master Out Slave In)
Function: Transmits data from the programmer to the target AVR device.
Connection: Connect to the target AVR device's MOSI pin.
Pin 4: MISO (Master In Slave Out)
Function: Receives data from the target AVR device and sends it back to the programmer.
Connection: Connect to the target AVR device's MISO pin.
Pin 5: SCK (Clock)
Function: Provides the clock signal for the SPI communication between the programmer and the target AVR device.
Connection: Connect to the target AVR device's SCK pin.
Pin 6: RST (Reset)
Function: Resets the target AVR device.
Connection: Connect to the target AVR device's RST pin.
Pin 7: VTarget (Target Voltage Sense)
Function: Senses the target voltage of the AVR device and adjusts the programming voltage accordingly.
Connection: Leave unconnected or connect to a voltage source (e.g., 5V or 3.3V) if necessary.
Pin 8: NT (Not Connected)
Function: Not connected or used.
Connection: Leave unconnected.
Pin 9: NT (Not Connected)
Function: Not connected or used.
Connection: Leave unconnected.
Pin 10: USB Signal
Function: Carries the USB signal for communication between the programmer and the host computer.
Connection: Connect to a USB cable, which connects to the host computer.
Connection Structure:
When connecting the programmer to the target AVR device, follow this structure:
1. Connect Pin 1 (VCC) to the target AVR device's VCC pin.
2. Connect Pin 2 (GND) to the target AVR device's GND pin.
3. Connect Pin 3 (MOSI) to the target AVR device's MOSI pin.
4. Connect Pin 4 (MISO) to the target AVR device's MISO pin.
5. Connect Pin 5 (SCK) to the target AVR device's SCK pin.
6. Connect Pin 6 (RST) to the target AVR device's RST pin.
7. Leave Pin 7 (VTarget) unconnected or connect to a voltage source if necessary.
8. Leave Pin 8 (NT) and Pin 9 (NT) unconnected.
9. Connect Pin 10 (USB Signal) to a USB cable, which connects to the host computer.
Important:
Ensure the target AVR device is compatible with the programmer and has the correct pinout.
Use a suitable cable or adapter to connect the programmer to the target AVR device.
Take necessary precautions to avoid damage to the programmer, target AVR device, or host computer during connection and operation.
By following this pinout explanation and connection structure, you should be able to successfully connect and use the AVR USB ISP Programmer with your target AVR device.
