STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Posted on February 01, 2018 at 09:37 Hi, I'm working on STM32F215 and I generate a PWM output on TIM1. This signal is going to an other device. For synchronization purposes on this signal, I would like to get the rising and falling edge of it. ...
Posted on December 05, 2016 at 17:45Hi folks,my application crashes occasionally with the above mentioned firmware package when data is transmitted to I2C devices.The crash is caused by following code in HAL_I2C_Master_Transmit: while(hi2c->XferS...
Posted on January 31, 2018 at 15:23I'm trying to use AN4759 to understand how to configure the RTC alarm for fractional seconds. As an example, I want to trigger an alarm every, say, 10.5 seconds.Pages 13 and 14 make reference to something that app...

Posted on January 29, 2018 at 16:35Seems like no matter what I try the .ifdef does not work. It always takes the default path.This happens with a symbol defined in the make settings as well as with symbols defined in any other way, including .equ an...
Posted on January 31, 2018 at 09:04HI.I am testing with ST Discovery LoRa Kit, PingPong.There is no problem sending / receiving 64 bytes.However, the size of 64 bytes or more can not be transmitted or received.Semtech says that 128 bytes are possibl...
Posted on January 21, 2018 at 19:32Hello,I use a STM32F072CB model with a battery connected directly to VBAT.So, I use the RTC hardware. I use CubeMX to generate the initialisation code.Unfortunately, each time the software start, the RTC registers ...
Posted on April 04, 2017 at 18:32I have a custom board with a STM32F769 and I am having problems getting the low speed LSE oscillator running. I am using CubeMX 4.19 to generate the low level code. In order to get the oscillator to run I need to set...
Posted on January 31, 2018 at 06:57 Good Day I have an ADC Configured for Continous conversion with DMA. I Periodically stop it and quickly process the data before starting it again. I would like to know how to process the data if I enable ...
Posted on May 26, 2017 at 01:19 Hello. I'm trying to use the RTC Alarm interrupt to execute code at a specific time interval. I did everything, but the interrupt code never gets executed. However, all registers seems to be properly set. Fin...
