Reading AT command response

Hi, I would like to read AT Command responses back from my ESP2866, as I want to check whether the response is "OK" or "Error". I made a function as below but it doesn't work properly.The plan is to send AT commands on USART3 and right after that, re...

Looking for STM32G0 information as in the ARM Cortex-M0+ TRM ?

dear all,My question is about the Cortex-M0+ options that were selected for the STM32G0 products (table 1-1 from the ARM Cortex-M0+ TRM). I can hardly find them in the STM32G0 RM and DS. Do you know where I can find the answer ?Regards

I2C2 stuck in timeout on STM32L4S9

HW situation is:I2C2_SCL on PB10 (pin L4)I2C2_SDA on PB11 (pin M4)Both have a pull-up resistor of 18K.The sensor attached to these lines is removed, so nothing is connected.This is not a dev-board but our own design.I have generated code through STMc...

Why my convertion time is not correct when the sampling time is less than 84 Sampling time ?

Hello,I'm using STM32f411RE with ADC and I would like to know why when the sampling time is less than 84, I don't find by calculation the same expected conversion frequency/time?My calculation is Tconv = (3+12)/210000Hz = 714 ns so a frequency of 1.4...
