Re: Overload protection setting

I was talking about external DC/DC power supply (with customizable voltage and current limit).
When you plug laptop power supply, it will start initial procedure where FLASH is communicating with other devices on board and you can not read/write FLASH during operation (bus conflict).

Re: Overload protection setting

Please check what is current consumption of your board when you use external power supply DC/DC powering it from the same pins as programmer (programmer disconnected). Programmer is limiting to 100mA/200mA but sometimes it's not enough and the only solution is to desolder the chip and programm it in...

Re: Ukp pro problem z ekranem?

Skrócenie taśmy raczej nie ma nic do tego, o ile jest równo ucięta, bo może być sytuacja że końcówki taśmy są postrzępione (w miejscu cięcia) i robi Ci zwarcie, obciążając układ zasilania. Jak jest za duże obciążenie (zwarcie) to włącza się limit prądu i moduł nie wstanie (może cykać). Jeżeli to nie...

Re: Prins LPG eVP-500 tank valve

Ok, usually this switch is outside ECM.
You can also check C3 signal T-ECT (or M1), seems like it may be ON/OFF controller

Re: Data Logger próbkowanie 10Hz problem

Sprawdziłem te ustawienia, mam dwa pytania: 1. czy wyświetlacz jest podłączony i wyświetla wskazania, czy UKP pracuje w trybie tylko android? Jeśli tylko android to trzeba w ustawienia -> ekrany -> autowygaszanie ustawić autowygaszanie włączone 0s. 2. na wejściu DS-B jest ustawiony czujnik temperatu...

Change signal source from LPG electrovalve, it will be constant +12V/0V

Re: Prins LPG eVP-500 tank valve

+4.4V is still fine for high state. Are you sure is it +4.4V between measured wire and vehicle ground?
It can not be software controlled, it's hardware input, low state <0.5V and high state >3V, so 4.4V is 100% fine and it should work.

Re: verify error after erase+write

It depends mainly on external circuit, you can have bus conflict (SPI bus is shared, MCU can communicate with FLASH when you power up it). There are some tricks and workarounds. Please read Chapter 5 for more details. If you share me more details about your external circuit how FLASH is located on b...

Re: verify error after erase+write

Are you programming in external circuit?
Please try to increase voltage +0.2-0.3V and decrease SPI speed to 50% or 10%. If it will not work, you need to desolder the chip and programm it directly in WSON8 adapter.
