AVR programmer

An ISP programmer for AVR microcontrollers.

FEATURES

- Faster than one which uses a legacy serial port.

- Simple circuit.

- Built-in FTDI's official driver.

- Built-in simple filer.

- Logging UART from MCU via MOSI pin.

LOGGING UART

- Logging via MOSI, not MISO. Non-inverting UART.

- New line is CR or LF or CR+LF.

- Only ASCII.

- In this mode, ADBUS0(TXD, SCK) and ADBUS2(RTS#, MISO) output H.

- SCK/MISO are not able to use as GPIO. Please set their DDR to input.

USB-OTG

- Please check that your phone supports USB-OTG.

- The phone catalogue which Google Play has may be wrong.

NOTES

- To make an adapter is required. Its schematic is in this app.

- The cost of parts is about US$20.

- The PDI/TPI are not supported, which are next generation interface.

- Only Intel HEX is supported.

- If your phone can not resume USB, you had better to disable sleep.
