This is a cheap little pen-like radiation detector/dosimeter from China that apparently could benefit from a lot of firmware improvements:

  • persistent cumulative dose after shut down
  • cps/cpm monitoring
  • pulse click with ability to enable/disable this
  • high dose-rates measuring improvements
  • temperature monitoring
  • power saving features
  • etc.

Here is a nice an thorough review of it.

MCU: ARM Cortex-M0 FM33LC043N MCU from Fudan Micro
Sensor: HH614 GM Tube
Battery: 150mAh LiPo cell - 50h promised

I'm urrently waiting for a SWD debugger to play with this. Let me know what else I can provide and how I should go about this.

Sorry for reviving this but I managed to dump the firmware of this device. SWD port is not locked as previous thought.
I used a J-Link device (actually a ST-Link V2 clone flashed with J-Link using STLinkReflash) and I managed to dump it with J-Link Commander as well as with Keil µVision V5

For J-Link Commander I dumped it with   
savebin C:\Users\jonah\Downloads\HFS-P3_dump.bin, 0x0, 40000

For Keil µVision V5 I dumped it with
SAVE HFS-P3_dump.hex 0x0, 0x3FFFF Then converted the Intel HEX-386 file format to binary using hex2bin.exe

Also, here is the datasheet in English:

The FM33 is quite different from the STM32. This would require a lot of time and motivation, which I currently don't have.

I can understand that. Thanks anyway! 🙂
In the meantime I found some interesting developing sources for FM33LC0xx here on GitHub. In case anyone else is brave and knowledgeable enough to hop on this I'm willing to help with testing.

PS. I also posted all this in that radmon.org post as well since that’s where this thing started

One more thing... could you test #97?
