Interrupts can occur while a delay is 'running' So Delay 1s - UART Rx interrupt(s) - add chars to circular buffer.... .. Delay finishes - process input.. The delay does (in effect) while (ms < 1000) ms = Getms(); On an interrupt - the processor saves the current context - performs the interrupt code...

Ah yes. I was still on the web...

Thanks for that....

? - you got me on that one.. Can't find that 'button' anywhere???

Guess I always did lack style

Hi Steve,

Click on your name - top right - used control - board preferences - my board style. You can choose 'element ' or prosilver.
Prosilver is a light scheme like the old board..

It's strange - I modified: avrc_arduinoA.bat - :ProgFlash @SET AVRDUDEcmd="%~dp0..\bin\avrdude.exe" -p m328p -P%ComPort% -b %BaudRate% -c %2 -D -U flash:w:"%FileName%" @SHIFT @GOTO Send :Config @SET AVRDUDEcmd="%~dp0..\bin\avrdude.exe" -p m328p -P%ComPort% -b %BaudRate% -c %2 -u So I'm forcing a m32...

So - this is probably related to other issues - but couldn't find the topic :-( If one of the other VCs wants to move this across then please do... I tried to program an Arduino Pro (maybe it's a mini?) 3.3v. This doesn't have a USB port and programming is via a FTDI convertor. Anyway - using the Pr...

I wanted to highlight the education packs at https://www.flowcode.co.uk/education/ - complete, well presented courses on 'embedded internet', 'canbus', 'RFID' amongst others.

What an excellent resource - many thanks to MatrixTSL for making this available.

Thanks Ben,

Mouse wheel - that's great. Now I can read the pin labels... 5v & 3.3v swapped top RHS, VEXT marked as GND pin 4...

Using CAL SPI - if 'use chip references' is unticked - then, for example, having (Software mode) MOSI = $pin15 gives compilation error (port5 doesn't exist did you mean portA?)

Should there be 2 available channels for SPI?

Just trying to get ESP programming working - and encountered a few things which I'm not sure about.. 1) If the program 'falls' off the end (loop: goto loop) then I get watchdog timer fired - program didn't respond in time - message on the uart. This is if auto clear watchdog is set/not set. It doesn...
