Test to see if the built-in charger stops at 4.20V (it stopped at 4.15V).Change the mode from Simple UI to Advanced.Measure the beam intensity on Turbo with my DIY lumen tube.Īfter updating the firmware on the MT04 I did a few more checks:.Test to see if the torch turns on and off.There are so many enthusiast who have made helpful tutorials.īefore I updated the firmware I did some basic checks: If you have a different torch, please check out the discussions on budgetlightforum and reddit. Thank you for reading! I hope that this tutorial helps you with updating the firmware on your own Mateminco MT04. ![]() If you get the following error then you may need to make sure that the pogo pins are touching the pads and the jumper wires are not broken: avrdude: verification error content mismatch Writing | # | 100% 2.70sĪvrdude: verifying flash memory against To disable this feature, specify the -D option.Īvrdude: input file auto detected as Intel HexĪvrdude: reading input file for flash Reading | # | 100% 0.01sĪvrdude: Device signature = 0x1e930b (probably t85)Īvrdude: NOTE: "flash" memory has been specified, an erase cycle will be performed Sudo avrdude -c usbasp -p t85 -u -Uflash:w:Īvrdude: "safemode" feature no longer supportedĪvrdude: AVR device initialized and ready to accept instructions Connect the pins to the pads and test the connection. Here is what that looks like: Steps for loading the hex file onto the torch ⌗ġ. Pad TypeĬonnect programming pads to the 10-pin ISP adapter using pogo pins: Pad The MT04 has six programming pads on the driver board near the spring in the head of the torch. Pin 1 starts at the top left where the ISP connector is viewed with the USB plug on the left and there is a little notch half way down the left side of the black ISP connector. Here is what the pinout looks like for the USBasp programmer and the driver in the torch. You will need to understand what the pins and pads connect to and how to hook them up together with jumper wires. You should now see in the anduril folder. Install bzr and download the Anduril 2 source code ⌗Ĭd ~/anduril2/ToyKeeper/spaghetti-monster/andurilĮcho "#undef USE_SOS_MODE" > cfg-mateminco-mt35-mini.h I used a Raspberry Pi 4 running Ubuntu 22.04 LTS. You could also use Windows or macOS (there are more tutorials on budgetlightforum and reddit). You could use an Android phone with ZFlasher AVR and an OTG adapter but you will need to compile Anduril 2 somewhere or download the hex file () and transfer it to your phone first. Ubuntu) and a spare USB-A port to plug the USBasp AVR Programmer into. To follow this tutorial, you will need a PC running Linux (e.g. Preparing your environment and compiling Anduril 2 ⌗ I have also bought a VEML7700, TSL2591 and MCP9808 sensors from Core Electronics and used those sensors to review the performance of torches. I have provided links to products on their website because they are a local electronics business in Australia and I like to support local businesses where possible.
