STM32 HAL 101 – UART – Receiving arbitrary length string

Despite the fact that UART communication is the simplest and mostly used one, there are some problems or limitations that we can face when coming from other more complex communication protocols like, for example, USB. The first problem that we can find is the lack of having an efficient way to receive an arbitrary amount … Read more

Announcing the HW-USB-CAN – A Highly integrated USB-CAN Sniffer based on STM32

I had been looking for this kind of products for a long time without so many good results (maybe I’m not so good in searching :P). Tha main key-features that I was looking for were: Being based on STM32, that is where I have more experience and I can customize and develop my own firmware. … Read more

HW-MODS: A prototype board for the STLINK-V3-MODS

Since STMicroelectronics presented it, I had been very curious to try it. There where all the specs for being a very usefull thing: a cheap and really small debugger intended to be integrated on every custom PCB that needs onboard debugging capabilities. I have immediatly decided to develop my own PCB in order to get … Read more

Say welcome to the OpenDAQ

An open source data acquisition board based on the STM32F4.
Features:
-10x extremely high resolution analog inputs (32bit primary ADC+ 24bit secondary ADC)
-4x low res analog inputs (12 bit embedded ADC)
-4x NPN logic isolated digital output
-2x programmable analog outputs (12bit DAC + op-amps)
-PC connections available over USB or wifi (nrf24 or esp8266)
-2x I2C interface
-4x UART/USART interface
-1x SPI interface (shared with nrf24)
-Expansion GPIO for extra CAN, digital inputs/outputs, 3v3 regulated power supply, usart, i2c connections
-Wide operating input voltage: from 6,5 to 36 Volt

Additionally to the STM32F4 you can use an ESP8266 to develop custom Wi-Fi application. It is interfaced with the micro by uart.

More information about price, availability and a getting started guide will be made available soon..
