# tinyUPDI - Minimal UPDI Programming Tool for tinyAVR
## Description
This tool allows tinyAVR series 0, 1, and 2 microcontrollers to be programmed using a USB-to-serial converter connected in a special way to the UPDI pin (also called SerialUPDI). More information can be found [here](https://github.com/SpenceKonde/AVR-Guidance/blob/master/UPDI/jtag2updi.md).
## Preparations
If necessary, a driver for the USB-to-serial converter used must be installed.
## Installation
- Install [Python3](https://www.pythontutorial.net/getting-started/install-python/).
- Install [pip](https://pip.pypa.io/en/stable/installation/).
- Install rvprog:
```
pip install tinyupdi
```
## Usage
Connect the USB-to-serial converter via USB to the PC and via the circuit described below to the UPDI pin of the microcontroller.
```
USB2SERIAL tinyAVR
+--------+ +-----------+
| RXD| <------------+---> |UPDI (PA0) |
| | | | |
| TXD| ---|1kOhm|---+ | |
| | | |
| VDD| -----------------> |VDD |
| GND| -----------------> |GND |
+--------+ +-----------+
```
Alternatively, a pre-assembled [SerialUPDI programmer](https://github.com/wagiminator/AVR-Programmer) can be used.
```
Usage: tinyupdi [-h] [-d DEVICE] [-e] [-f FLASH] [-fs [FUSES [FUSES ...]]] [-t TRIM]
Optional arguments:
-h, --help show help message and exit
-d, --device set target device (if not set, it will be auto-detected)
-e, --erase perform a chip erase (implied with --flash)
-f FLASH, --flash FLASH BIN file to flash
-fs [FUSES [FUSES ...]], --fuses [FUSES [FUSES ...]]
fuses to set (syntax: fuse_nr:0xvalue)
-t TRIM, --trim TRIM configure oscillator for given frequency (set fuse 2)
Example:
tinyupdi -f firmware.bin -fs 6:0x04 7:0x00 8:0x00 -t 8000000
```
