Posted on May 18, 2017 at 09:45Hi,I use a Nemeus pico gateway and a B-L072Z-LRWAN1 with the I-CUBE-LRWAN software.I displayed uplink message with a python scrypt running on a Raspberry Pi.Nevertheless, i can't see downlink message like the join acce...
Posted on May 23, 2017 at 11:39Hi, I'm using the STM32L152C8U6-A MCU. I want to use the high speed external clock signal (HSE). The HSE is specified for frequencies from 1-24 MHz. I have an 26 MHz crystal oscillator. What happen, if I still use the ...
Posted on May 22, 2017 at 11:05Hello,I'm working on a project in which there is an inter-board I2C link between the master MSP430F5438A and the slave STM32F207IG. Now whenever the master MSP430 resets(due to the external watchdog), the PE bit (Perip...

Posted on May 22, 2017 at 10:49Hello,I recently bought the STM32F769I-DISCO to learn and do independent work with the M7-Cortex MCU series, and decided that the features of this board would be sufficient for such work, having special interest in wor...
Posted on May 23, 2017 at 00:19 hello, I am working with this MCU for the first time, i used AVR until today, I would like to start with a minimum circuit to do some experimenting. I m using this schematics but i don't have any idea if is goo...
Posted on April 27, 2017 at 09:20Hello all,I'm trying to setup the STM32L476RG via SPI with an external DAC (SPI clock speed: 40MHz). I used the HAL_SPI_Transmit() function to transmit a 24Bit word.After one transmission there is a gap of 2.5�s befo...
Posted on December 07, 2015 at 18:33 I have the DAC output of my STM32F44 feeding into a non-inverting op amp. Everything is working, but not real great. The problem is at the lower end, and gets worse the closer you get to zero. For ins...
