Flowcode Support Board

Hi Ben

On my board I have AXP192 Power management IC.
I like to read a register and later write in the register
I have a sample code but I don't know to translate this in flowcode.
I'm always reading 255

here the democode:

uint8_t AXP192::Read8bit( uint8_t Addr )
{
Wire1.beginTransmission(0x34);
Wire1.write(Addr);
Wire1.endTransmission();
Wire1.requestFrom(0x34, 1);
return Wire1.read();
}

Here my program: Some info about all the register:

Hi Stefan,

You were on the right track.

Give this a whirl, fingers crossed

Here's another version with the write function.

Hi Ben

I tried both versions but I always get 0. With the oscilloscope I have clock and data on the correct pin.

Hi Ben

I think the register 32h is 0.

I tried some another register with your first code and there I get the correct value.

Hi Stefan

In the example code there is a far bit in the initialise function code. It might be it needs setting up to work as expected?
