Re: Some pins not usable when using ST-Link ?

Yes, I am aware of this. Still, when using DFU upload method, the full JTAG debug pins are assigned for debugging even if only SWD connector is on board, and I don't really see why would be this useful for "majority users", someone can please explain. I agree. If someone uploads via bootl...

Re: Setup of STM32F104CBT6 board

If you have a USB to Serial converter, you can flash the bootloader using that, instead of the sketch.

But, the sketch always worked for me. But perhaps some vendors started to lock the bootloader flash pages.

Re: Open Energy Monitor

Excellent! i have plenty of nRF51 modules kicking around, so I may build this when I get time. BTW. I think in the long term that Sandeep Mistry's "Arduino nRF5" repo will definitely supersed mine, as his is a much cleaner implementation than the RBL one, as his is not based on mbed. Howev...

Re: Open Energy Monitor

Off topic -- but I built the energy monitor based on Bluetooth chipset. The project uses nrf51822 module which can be programmed in Arduino. Source code: https://github.com/ardyesp/PowerMeter Its pretty accurate. Interesting .... Which Arduino core for nRF51 did you use ? One of the ones I made fro...

Re: Some pins not usable when using ST-Link ?

I'm confused now

People wanted the SWD pins enabled all the time, so I changed it.

Is this not what was wanted by the majority of users?

Re: Lib for ILI9486 - 3.5 inch 480x320 touch TFT for RPi

@stevestrong Looks good. Things are often not to difficult to implement once you have worked out what to do. However its the R&D to work out what to do thats the difficult and time consuming thing. @Squonk42 Luckily the STM32 SPI speed (and most other parts of the MCU) are operate well beyond it...

Re: Advice sought regarding mesh networking devices

Steve Sounds like you need some serious high end system. You probably need to post to the various specialised forums, for the manufacturers of networking systems, or possibly a dedicated networking section on sites like the EEVBlog forum, or even the Arduino.cc forum's networking section (However I ...

Re: Advice sought regarding mesh networking devices

You have not said what range you require. This will make a big difference in your choice of RF hardware. Also does the link need to be encrypted ? Your basic description glosses over the mesh part of the system e.g. where master cant communicate directly with specific nodes, and there data is relaye...
