Error calling smart contract functions with parameters

[RodrigoRP7]

Hi!

Thanks for your awesome work, your library is great and has saved me lots of time and headaches.

I am using it with an ESP32 WROOM and I've been able to: 1) Send transaction to address 2) Call smart contract functions 3) Send transactions to smart contract functions without parameters.

However, I get an error every time I try to send a transaction to a smart contract function that contains some arguments. Here is an example:

Working

C++ code

string param = contract.SetupContractData("modifyNumber()"); 
string result = contract.SendTransaction(nonceVal, gasPriceVal, gasLimitVal, &contractAddrStr, &callValue, &param);

Solidity code

contract Test {

    uint8 public number = 20;

    function modifyNumber() public {
        number = 100;
    }

}

Not working

C++ code

uint8_t newNum = 100;
string param = contract.SetupContractData("modifyNumber(uint8)", &newNum); 
string result = contract.SendTransaction(nonceVal, gasPriceVal, gasLimitVal, &contractAddrStr, &callValue, &param);

Solidity code

contract Test {

    uint8 public number = 20;

    function modifyNumber(uint8 newNum) public {
        number = newNum;
    }

}

Error

The error occurs in contract.SetupContractData(...), whenever the provided function contains some parameters. The output error is of type: Guru Meditation Error: Core 1 panic'ed (LoadProhibited). Exception was unhandled

Thank you in advance!

I just found out that the SetupContractData() function does not interpret uint parameters with size different than 256 bits. In my case, I was trying to pass a uint8, but this is not defined in the library function. Maybe this could be an interesting upgrade to allow optimization.
