I've tested tested with 2 units one connected to can hacker (transmitter) and the other one connected to P-Can view (receiver) and played back some data that I've recorded.
And I can confirm it and it all works perfectly ![]() |

You cannot use the programs from ST, you must use the software from Geehy.Geehy DFU Programmer is used for DFU upgrade of APM32 series MCU.
https://www.geehy.com/uploads/tool/AN1081_APM32F4xx_Quick%20Start%20Guide.pdf After you have converted a st-link to a j-link, for example from a Nucleo development board from ST, you will use the j-flash software from Segger to program the mcu, not the software from ST. You will need to connect the boards to be able to program. Update: Yes, use tools from Geehy. |

You can transform st-link in j-link https://www.segger.com/products/debug-probes/j-link/models/other-j-links/st-link-on-board/ I've just tried that and it reports no J-Link or ST-lik connected even though it is and I've pulled high the BT0 pinBut I haven't used any stm32 "clone", I don't know for sure if it will work for Geehy APM32F407VGT6, but you can test. That's the problem I've tried STM32 Cube and ST-Link software but both report NO ST-LINK detected on ST-LINK and no DFU on ST-Cube, Not sure if a boot loader is installed on these boards. This the link I clicked on the wrong one and not did not notice https://www.ebay.co.uk/itm/155813582240?hash=item24473695a0:g:J5QAAOSwMSRlH6uH&amdata=enc%3AAQAIAAAA4IKMLNJULr82n%2FIM3Gra5lFas6AWvjNkcBYr37spjk87o4HxooZbVSzAMfVTJRDRQKN8pdgDvgRUbtPiU%2FXUludle1%2FfBLOsm8mzaJ%2FHNOiUWTRTzVxn826c0NpeWx2ZOS38FDj9jywJv%2BW8hX2S3c76bfu1CRbVbr%2B6Qd3B6mjmfdCA0DPvl%2BbstSRNskEdICQtZSt8kH%2B%2F7Lqio9z4v4tcJfSir6AQLG98cOKm6x4BkIPr5w%2B6mwbQw12QissgEJmKrXw4aq%2FDyw4iQaD9al7IA2JpF%2FknhHhXtLmEr92X%7Ctkp%3ABFBMupSJo4Vj UPDATE: I've found what can upload program to it just carrying out some testing, Lets see how it goes found it here https://global.geehy.com/support/apm32/?id=383 |

I’ve made a big mistake and ordered some of these APM32F407VGT6 instead of these STM32F407VGT6 and realised when I could not get to upload the hex file using the st-link
Opps! |

I found the TCXO and it is quite expense option. I had Pi Pico on the shelf and I was thinking to overclock it to 200 MHz to clock the CPLD. this will be much cheaper than the TCXO.
The XTAL 25MHz + ICS511 shall be a perfect option. The price of 10 pieces of ICS511 is almost 3 euros. This is definitly good price. |

If you need a good precision with the frequency, you can find cheap 200MHz TCXO 0.1ppm on AliExpress (by Example) for near 12€ like this one.
An other solution is to use a XTAL 25 MHz and use an ICS511 (Multiplier) configured in Mult x8 (near 3€ at AliExpress). Best Regards. |

STMicro have a very good selection of ToF sensors https://www.st.com/en/imaging-and-photonics-solutions/time-of-flight-sensors.html I know about that and their solutions are in range of 5m or even less. The device I want to build has range of 1500m |

I watched this video and I am excited to build similar device : https://youtu.be/y7pbxEbqnVI
I want to build the project under 100 euros. Below are the components that were figured out in the video :
I believe that MAX913 will generate a pulse that indicate the time difference between transmitted signal and received one. The CPLD maybe used to read the duration of the generated pulse from MAX913. do you think my guesses are correct? Most online stores indicate out of stock components and I can't find oscillator for the CPLD to work at 200 MHZ. I was thinking to overclock Pi Pico to generate a fast clock but I am not convienced it shall be a good option. do you know a cheap oscillator operating at 200 MHz? |
