Counting mode of pyb1.1 Timer

I want to use the counting function of pyb1.1 timer. Unfortunately, I didn't use it in the experiment. I browsed the chapter about timer on the official website, but I didn't understand how to use timer.IC, timer.enc_A, timer.enc_B. who has used or can provide an example? Where can I read the value ...

UART interrupt received data exceeds the buffer size

Hi, I use UART(6) of pyb1.1,Firmware version is V1.11. The code is as follows #------------------------------------------------------------------ from pyb import UART,Switch WT901_ISR_flag = 0 key = Switch() def WT901_ISR(t): global WT901_ISR_flag WT901_ISR_flag = 1 WT901 = UART(6,9600) WT901.init(b...

Re: Use of timers

It's because of the need for accuracy that I think of using timers. I'll try to find out if there's a good solution

Use of timers

Can I use the timer of pyb1.1 as the fixed length controller? I have a 1.8 ° stepper motor and stepper motor driver. I send 200 pulses to the driver. The stepper motor can rotate 360 °. I want to concede that the stepper motor will stop after 3.5 turns (700 pulses are needed). Can pyb1.1 be realized...

UART function

Hello, I'm afraid that I'm from China. I'm using pyb1.1. When using the official firmware version v1.93, UART (2) can use UART.readline() to read a row of data normally, but this version can't use ssd1306. When using the official firmware version v1.11, ssd1306 can be driven, but the data obtained b...
