I solved this issue by having a payable fallback function by defining it as:

Turns out that I was using the address from the which I created the contract as the source address, instead of the newly address created by the new contract.

Try this code

You can add negative margin to the right and left of the divider that is equal to the outer padding.

I almost succeeded, now I have the problem that the answer is repeated ... any advice?

You need to convert that string into a Datetime object in order to add the hour. Try something like this:

If I was you, I would use swapExactTokensForTokens and call it as many as you want. you can even create a loop to manage if you have many cryptos to swap or if it's always the same, hardcode the calls. here is a quick example with DAI and USDT. you can replace the tickers with variables and use a loop if you want.

If particular ECU doesn't receive CAN frame within 300 ms timeout after powerup, it stops responding to any further frames and must be power cycled. This is a information from customer's technicians, I have to just believe it.

This does of course entirely depend on what task it is performing.

Generally, an ECU, as in an automotive computer in a car/truck etc is never allowed to hang up/latch up. The normal course of action would be for the ECU to either reboot/reset itself or revert to a fail-safe mode.

But in case of tractors and heavy machinery the normal safe mode is "stop everything".

It is possible to powerup ECU after CAN driver thread is ready, but it would require some extra wiring by end customers.

I don't know what this is supposed to mean. What is "extra wiring"? Something to keep other nodes in common mode while one is rebooting? Terminating resistors? Some dirty power-up delay circuit?

Software solutions are all bad or worse, like running FreeRTOS before important checks, put CAN driver code to code common with other products, or start CAN periphery in the bootloader and left running without software control until driver starts.

Generally speaking, it's custom to initialize critical hardware like clocks, watchdogs, prescalers, pull resistors etc very early on. Initializing hardware peripherals may or may not be critical. It's custom to do this after the CRT has been executed, at the beginning of main() and the order of initialization usually matters a lot.

If you have a delay longer than 300ms from power-on reset to the start of main(), something is terribly wrong with the program.

The sensitive part is, that we have no explicit demand to start CAN driver within such a short time in specification. Customer says, that it's part of J1939 specification.

I haven't worked much with J1939 and I don't remember what it says specifically, but 300ms is an eternity in a real-time system! It's not a "short time".

In general, correctly designed mission-/safety-critical CAN control systems in automotive/industrial settings work like this:

• All data is sent repeatedly in fixed intervals, regardless of if it has changed or not. Commonly once per 10ms or once per 100ms.
• A node which has not received new data will use the previously received data for now.
• There is a timeout from the point of when last valid data was received, when the receiving node must stop using old data and revert to a fail-safe mode. This time is often relative to how fast the controlled object can move. It's common to have timeouts after some multiple of 100ms.

I would say that your customer's requirements are very reasonable, it's nothing out of the ordinary.
