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 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...
