Hi I might have one somewhere to try. If I find it I'll see what I get but I think it was a cheap module so ended up in a drawer as it was not very good. Meanwhile, do you have a USB-TTL serial converter? If so, you could connect the Rx terminal of the converter to the UART Rx pin, open up a Termina...

Hi What I have noticed is that every time I close the program and open it, for example the next day, the pin configuration assigned to the keyboard is lost in FC. When you open the FC program again, the row and column pins are reset to the default values ​​in FC. Similar issues to this have been fou...

Hi

All components are now free, you just need to purchase chip packs for those not included as "free", and any required license if not for hobby use. Have you downloaded all toolchains and set their location in Global Properties?

Hi Following on from above, in FC the chart you posted doesn't constantly transmit. The component itself Waits for key press Gets value Waits for key release The only way it can then branch to actually send the value is if the value is less than 16 (0x10). I don't use Proteus so can't really advise ...

Hi If your clocks are correct you wouldn't really need "debounce" as:- You "test" and obtain a key press value, you send this value and you then wait for one second before "testing" again. If your clock was fast, that 1S delay may only be tens of mS. I always start by creating a one-second flash tes...

Hi Referente al valor FE, parece una actividad constante el el pin TX del Pic emisor That isn't happening in your FC chart / simulation so may be an issue in Proteus. Eso no sucede en su gráfico/simulación FC, por lo que puede ser un problema en Proteus. In Project Options you can set your oscillato...

Hi Sorry for the delay in replying due to travel. In a post above (11:38am) you show Proteus connections as Row on B0 - B3 and Column on B4 - B7 However FC has Row on B4 - B7 and Column on B0 - B3. This would certainly cause issues in reading the keypad. Both FC and Proteus need to have the same con...

Hi I don't use Proteus so I can't help with that. Your latest chart simulates correctly in Flowcode. When a key is pressed and held, the correct value is captured and stored in the array for transmission. Note though that this value only changes when you press a key and whatever is contained in the ...

Hi

I will let you know what I find using Hardware, but that will be later in the week

Les haré saber lo que encuentro usando Hardware, pero eso será más adelante en la semana.

Hi Thanks again for the response. Yes, I already see in the debugger and in the console that everything is transmitted fine. The problem is that at the output of the Tx terminal of the pic within Proteus, activity is seen but what the virtual terminal reads does not correspond to the values ​​that F...
