Re: Hello from Southern Germany

Hi Karin I have been experimenting with some LoRa modules, using the cheap BluePill STM32F103 board I find that LoRa library by Sandeep Mistry (on github) worked fine for the SX1278 modules, and I think the HopeRF modules have exactly the same interface so the same library should work for the Hope d...

Re: Hello from Russia

Welcome Aleksey

There are probably 6 or more people who are building systems for their cars or motorbikes.

So if you search the site, hopefully you will be able to find what they are doing.

Re: USB HID / USB MIDI as libraries

Re: Host To Host A few weeks ago, I did try to find if it was possible to send a command via HID, as its supposed to be bi-directional, but did not find anything useful There was a post on AVRFreaks where someone was using VUSB for HID and wanted to send commands to the AVR but he seemed to have a r...

Re: First experience review of allpcb, $5 for 100x100mm boards shipped

I checked again, yesterday and it appeared to be fully working again, but it sounds like their site is not well maintained.

(Which isnt surprising, as they must not be able to afford to spend much getting it maintained, when they are taking a loss on each $5 order)

Re: F405 & F411 versions of the BluePill

I've tested DFU upload on one F4 board, and it seemed to work every time. I checked the board and it does not have a pulldown on PA9 or PA10 I also checked the STM32 Stamp schematic (there is a copy in my repo in the STM32F4Stamp folder) and that board does not have a pulldown on PA9 or PA10 (it can...

Re: keypad library

No

Thats just your sketch that uses a file called keypad.h

Your sketch does not compile if I select Arduino Uno in the IDE

Re: Hi from poland.

Interesting idea I think that should work, because it does not need much processing and the MCU is very fast So for output pixel X,Y ( X is along the scan line, Y is the scan line number), The output GPIO pin gets turned on if abs(ADCBUF[X * X_RESOLUTION] - Y * Y_RESOLUTION) < THRESHOLD and if the p...
