Posted on February 01, 2018 at 21:57I am using a STM32F427 MCU and have trouble understanding the stop mode behaviour I am experiencing.I use the RTC periodic wakeup event to wake from stop mode (WFE - using event only). The the correct EXTI line 22...
Posted on January 30, 2018 at 12:30Hi, I have an uart at 115300 baud rate and I miss data.I have implemented the rx callback where I grab one byte at time.How can I grab more than one byte till the end of the receive?HAL_UART_Receive_DMA(&huart1, (u...
Posted on January 30, 2018 at 21:53Hi. I need to change the uart baudrate dinamically.I have tryied this but sems to not work. Have you got an example to show? serial->Init.BaudRate= BaudRate; serial->Init.WordLength = UART_WORDLENGTH_8B; s...
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 ...
