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...
Hi,I am working on stm32f051c8t6tr microcontroller, from this I want to read some sensor data with UART1 and same data I want to transmit to another UART. Can you please suggest some example code related to my task. I am new to this controller.I have...
We have a project in which we acquire 12 ADC channel with a 600 samples per channel. The data acquisition works, but the end of the array never gets written to by BDMA.I have cross-checked the behaviour with the NUCLEO-H723. Basically same configurat...
The descriptions of FLASH_PECR bits 1, 2 (PRGLOCK, OPTLOCK) on page 103 appear to have the meanings of 0 and 1 swapped. For example, referring to PRGLOCK (Bit1) the RM says:0: The write and erase operations in the Flash program memory are disabled.1...
I understand that there are many sensors available on B-L4S5I-IOT01A . But I am not able to find any tutorials or sample code for reading data from these sensors. If there is anything can anyone in this group help me
Hi all I am working in the implementation of Bacnet MS/TP protocol in stm32g431 using rs485 can any body guide me about the stack available.Thankyou
Hi there,I am looking at STM32G031Kxxx (32pin LQFP) and am wondering whether it is possible to provide an external high speed clock source to this µC?The datasheet shows that in this package OSC32_IN and OUT are available, but for the HSE, there is o...
We have another problem with EEPROM emulation. We use STM32H723Z and store user configuration to flash as emulated EEPROM. I used driver from the H7 examples' directory as a basis.When we write the configuration heavily, after few days, there occurrs...
Hello.I have a custom board with STM32F411RET6. I need to use SPI1 to communicate with an RF chip. I'm using HAL and FreeRTOS. I need to use DMA, since it's a high-throughput application. I'm not using CubeMX.The problem is I can't get any IRQ to fir...
Hi All,The idea, to use variable length data on UART receiver is that "Use a timer ",I am using a timer with interrupt, Once the first byte is received timer start and on second byte receive timer STOP and store the data and start the time again, At ...
Hi community,This question is all about the behavior of the DMA1_Channel1_IRQHandler in my application.I am working with an STM32G431CBT. It is running at 168MHz. Configured with 4 Flash wait states.NVIC interrupt priorities are setup using CMSIS fun...
