Re: CANbus... on ESP32

Hi

Glad to hear it is running.

Depending on whom you buy from, ESP boards can certainly have conflicts as accurate documentation seems a distant afterthought.

Re: CANbus... on ESP32

Hi Not at a PC just now so can't really check for your chip, however not all pins on ESP devices are actually available for general use. Some are used for such things as internal Flash and communications or are read-only. If you have a datasheet specific to your board (and can share a link) it shoul...

Re: Loop While!

Hi Much like Jorgen I had to retro fit to an existing door. Owner had wired up himself using keyswitch but no endstops, so magnetic contacts were used to electrically stop when fully open/ closed via appropriate relays (motor did have an inbuilt cut out if "stuck"). RC was added later in t...

Re: Analog Pin Configuration for PIC16F84A with Potentiomete

Hi

Im not at a PC just now so can't offhand recommend a direct replacement, but there are many similar PICs that do support ADC.

Re: Analog Pin Configuration for PIC16F84A with Potentiomete

Hi

As far as I remember, the 16F84A doesn't support ADC function on any pin.

You could use an external ADC or any one of a number of similar PICs that do support ADC.

Re: bug with pca9685

Hi Travelling at present so I cannot test on HW, but I have used this component in the past without issue. That said it was possibly v9, but point being it worked. I'm always a little wary when people say something or other doesn't work when all they are doing is simulate in 3rd-party software. Try ...

Re: Tool adon

Hi

I will just check my crystal ball...... Nope nothing there..... :)

Perhaps if you were a bit more specific in your issue and perhaps attached a chart it would help us to assist you further.

Re: ST7789 gLCD and Arduino nano- Slow Display response

Hi

Sorry, I overlooked that you were using v9. Unfortunately I don't have v9 on this laptop.

Hi

If you go to properties on the display, scroll down you will see option for scaling.
