I am a new member, I am learning about UART data transmission of MCU STM32F411RE on a nucleon board. I have read and understood the function HAL_UART_Transmit. However, in this function, there is a part I don't understand. I don't understand the mean...
Hello everyone,I am trying to install STM32cubef3 patch v1.11.2 ,the zip file download from st web site, and I already installed STM32f3 v1.11.0, but when I use embedded software packages manager choose the zip file, it always display "Missing depen...
1. It is correct to read and write flash through command function when there is no memory mapping enabled（ flash:MX25R6435F ）2. After memory mapping is enabled, after accessing the address of 0x90000000, the MCU crashes and cannot recognize the chip....

Based on the info in the STM32 reference manual, I would have thought this code to start up the WWDG would work (after processor reset). // sets up the WWDG with a period of about 1 sec, no lower limit inline void StartWwdg() { LL_APB1_GRP1_EnableC...
Hi together,I have ADC reading issues with my STM32G431. I read the ADC with DMA. The readings are triggered by a burst of pulses (approx. 750 kHz) and the ADC buffer seems to get filled. However, the ADC readings are way to high.A 2.5 voltage regula...
Hello,I am trying to recognize a number sent to USART:If I send '123' over USART to MCU then MCU receives only '3' (the last character). Variable recv has uint8_t (unsigned integer) type. How could I receive the complete number ('123')?I am using STM...
Hai,I just want to enable the gpio through the LabVIEW using VISA communication, for this how can i make changes in stm32 firmware code to enable the gpio through the labview, if anyone have idea about to how to write the firmware code to access the...
The description of DMA_CMARx (and also DMA_CPARx) register in single-port DMA (AN2548) says:This register must not be written when the channel is enabled.What wrong may happen if this register is written when the channel is enabled?This of course is ...
