WriteString needs the '&' removing from the code block too

Back from my travels and the FRAM chips had arrived :-) I wired one up - and using an Arduino and a logic analyser found LOTS of problems with my former code (oops). So - this works - with the proviso that I've only tested writing and reading arrays of 20 bytes to address 0 - the values of the array...

I don't have access to any hardware (or indeed Flowcode) at the present. However, i would try and create a single macro Blink (count, pattern1, pattern2) rather than using individual macros for each time period. Select the patterns using a lookup table (either the component or an array) with index a...

Hi Stefan,

Sorry - I'm away from home at the moment - and no access to anything to test...
What are you getting in the menuconfig ? I think you need a fullclean / rebuild (or change another menu setting, rebuild) after adding the tinyusb library before it shows up?

I think in theory - you could get 115200 baud using C at 32MHz - you have 69 instruction cycles per bit (@8.7uS)

It would take some careful coding though...

Using the EUSART hardware is easier!

Leigh beat me to it...

Can i ask how you are timing this? In theory you can get a 1us delay using a timer (with interrupt) or with some nop instructions. So something like: LATA0 = 1; // Set RA0 high DELAY(); // delay also has function call overhead. LATA0 = 0; // Set ra0 low Will take longer than 1us due to the function ...

Fleshing things out slightly... I added a character map - I think the uppercase letters are more successful than lowercase, as the sizes vary for lowercase in a jarring manner. It supports all the printable ASCII characters ' ' .. '~' (95 characters) This tested with the HT16 chip (and should work w...

Some progress? Compiling okay now? Does it appear to connect to USB with a new port?

Can you post your code so far?

ht16k33.jpg Note that the display is just 'plugged' into the Arduino - and is upside down - dp at top left! I just photographed a 'random moment' - and digit 4 is yet to change to reflect the others (probably should have added a delay!) The digits look rather brighter - and the off segments are far...
