STRUCT W1_UART_LIMITS(9)

💖 struct w1_uart_limits(9) 💖

okay bestie, welcome to the Kernel API Manual — we're doing 1-Wire timing limits today and it's lowkey iconic. no cap, this struct is the little vibe check that tells you what timing sitch your 1-Wire operations are working with. let's get into it 🎀✨

🌸 NAME 🌸

struct w1_uart_limits — limits for 1-Wire operations. literally the boundaries, the parameters, the whole timing mood board 💅

✨ SYNOPSIS ✨

       struct w1_uart_limits {
           unsigned int baudrate;
           unsigned int bit_min_us;
           unsigned int bit_max_us;
           unsigned int sample_us;
           unsigned int cycle_us;
        };

• baudrate — the requested baud-rate that's gonna create the 1-Wire timing pattern. it's giving "make it match the rhythm" energy fr fr.
• bit_min_us — minimum time for a bit, in us. the floor, bestie. the absolute least. 🫶
• bit_max_us — maximum time for a bit, in us. the ceiling. don't exceed it, iykyk.
• sample_us — the timespan used to sample the 1-Wire response. that's the window where we're like 👀 bestie respond.
• cycle_us — duration of the 1-Wire cycle. how long the whole cycle runs. periodt.
