Martin beat me to it...

Please post your chart (or a sample) to demonstrate the issue - I would guess an issue with the read logic, maybe reading unset bytes from the buffer?

There is probably something similar in the FC component catalogue... For a little fun - I did a MAX7219 component - I have an eight digit display - but the number of digits can be changed - although the modules can be linked I haven't allowed for that here - max number of digits is 8. It allows digi...

The pins for the display are also incorrect - and can't be edited in either hardware pr software mode - which looks like an issue with the
LCD component. The Nano needs these to be set to port B - as mentioned above...

Testing a new PICKit5 - and wondered how easy it would be to use a PICKit5 to upload code to a PIC. Very easy - in the compiler options tab: Select 'programmer': Then select PICKit3 IPE External Power (or PICKit 4 IPE...) I needed to point the Location to the ipecmd.exe file (and you'll need to use ...

The esp32 doesn't really have any EEPROM - you can use flash memory as persistent store, or the RTC has some memory that is non-volatile too.. There is a post about SPIFFS and also using RTC memory - though will take a bit of searching.. https://www.flowcode.co.uk/forums/viewtopic.php?t=2642&hil...

There are some interesting algorithms: Depending on how often you need to reverse the bits of a byte 0 - the quickest technique is probably a lookup table rev[256] Where : rev[0] = 0 rev[1] = 0x80 rev[2] = 0x40 etc Then to reverse a byte rev_byte = rev[byte]. See also Hacker's Delight (Henry S Warre...

The buzzer component only turns a pin on (or off) to play a tone - which is a feature of the buzzer hardware.... The frequency value is only for simulation. It might be possible to alter the tone using PWM either with the buzzer device or by outputting directly (via a transistor or amplifier) to a s...

I can't replicate the issue (I think you've mentioned it before) - I tried PuTTY and idf.py - p COM6 -b 115200 monitor - and both work as expected with / without the interrupt. Which terminal program are you using? There is definitely some repeated data that is 'correct' (A0:B7:) - but then everythi...

Hi Stefan,

Default string size is 20 - and if somewhere there is a 'make a copy' box checked that might explain things? Passing strings by reference (not copying them) is usually the preferred option - and quicker too - but the default seems to be to pass by value.
