Printf output, with buffer with a value of 0?
I have a message from an external device, that gets filled into a buffer. This is a raw binary in terms of data. I would like to see this data in my terminal screen.

Triac Circuit Advice for Zero Crossing
So 35mA will grantee that triac will fully open. So i am correct my calculations show a 800ohms resistor would be needed.    Does this seem correct? As AN mentioned 100-...

Triac Circuit Advice for Zero Crossing
Ok   From what i have understood, i will also need to use Vgt and Igt to calculate the ideal resistance value.   So am i correct that for the triac selected: VGT = 0.7V...

Triac Circuit Advice for Zero Crossing
This is the datasheet for my device,   BT137S-600 (mouser.co.uk)   Seems there is not voltage Vs current for the gate.

Triac Circuit Advice for Zero Crossing
Thanks   I have changed R2 100ohms, as my calculations have shown minimum resistor for 24V is 33 ohms but 100ohm is widely used among my PCBs. I guess I have a little extra...

SAMD21 Writing To unused part of the Flash?
So that i am understanding it correctly.   If my bootloader becomes 75K( Due to a downloading firmware over wifi), i can then set my application memory to be between 80K-256K?

SAMD21 Writing To unused part of the Flash?
I have existing project, how can i change where the application start address is?   It seems the default is set to 0
