Description

Overview

Mini HV UPDI (High Voltage Unified Program and Debug Interface) programmer for the new megaAVR 0-, tinyAVR 0- and 1-series microcontrollers built on ATtiny1604/1614 based on the design and the firmware by Dlloydev (https://github.com/Dlloydev/jtag2updi). The Mini HV UPDI programmer will enable you to use the additional configuration settings for the UPDI pin without the fear of getting locked out from the MCU. It features 3 programming modes: UPDI, HV or PCHV, with the target voltage at 5V.

Uploading Firmware

SELFPRG Jumper Settings:

SELFPRG Jumper Prog Mode
no jumper Normal operation.
pins 1-2 shorted UPDI - Uploading firmware or installing bootloader via UPDI header using another UPDI (HV) programmer. This is necessary when no bootloader is installed.
pins 2-3 shorted USB - Uploading firmware via USB. An installed bootloader is required.

Operating Instructions

MODE Jumper Settings:

MODE Jumper Prog Mode PA0 Configurations HV Pulse Power Cycle
no jumper UPDI UPDI NO NO
pins 2-3 shorted HV UPDI, RESET YES NO
pins 1-2 shorted PCHV UPDI, RESET, GPIO YES YES

Modes:

Mode Function
UPDI Mode This mode would be used when the UPDI pin is configured as UPDI or for any target device that isn't HV tolerant.
HV Mode This mode applies the 12V UPDI enable sequence (HV pulse) at the start of the programming sequence. This temporarily reconfigures the UPDI/Reset pin to UPDI mode which will remain in this state until the next power on reset (POR). This allows programming to occur when the pin is configured as Reset. A POR needs to occur for any fuse setting changes to take effect.
PCHV Mode Power Cycle High Voltage mode (PCHV) will initiate a power cycle and HV pulse at the start of the programming sequence. At the end of the sequence, a second power cycle will occur which causes any new fuse setting to take effect. The power cycle OFF duration has been set to 10ms. This mode would be used when the UPDI/Reset pin is configured as Reset or as GPIO.

Status LED Operation:

LED Status
PWR STEADY ON when programmer is powered
PRG STEADY ON when in programming mode
HV FLASHING at HV pulses during programming
