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...
In the manuals it usually says that the 16-bit filter includes 11-bit STID, IDE, RTR and EXID[17:15]. Does that mean that if standard CAN IDs are used, EXID[17:15] covers the r0-bit and two highest bits of the 4-bit DLC-field? I haven't found that me...
Hi hello,As iam new to stm32 i don't know how to use CAN bus to transmit and receive through CAN bus analyzer to stm32f4 controller, could some one help to give some sample or example code to send and receive message using CAN bus analyzer to stm32f4...
I want to decrease the reference voltage of the ADC to have a better resolution, is it possible to do it?Could someone explain me how can I do this? I am using the Nucleo-64 board STM32F030R8 and CubeMX to generate the code. Do I have to configure so...
Hi, I'm using an STM32F301 chip to write to a display, so I need a lot of data to be transferred to it. The chip is configured as an SPI slave and the data is received via DMA. My issue is that the DMA receive buffer takes too much space in RAM becau...
I'm not a hardware engineer, so apologies if this is a stupid question ...I have two STM MCUs communicating over an open-drain line which has a pull-up resistor. Each MCU has a GPIO port connected to the line, and the ports are configured open-drain,...
I want to interface temperature sensor LM35DZ with STM32F103C8T6. I wanted to know whether we need any signal conditioning circuit between the sensor and the STM32 or not. If yes, then I wanted to know the exact circuit using voltage divider and the ...
Hello,I'm working on an STM32F411 and I'm using two peripherals : one SPI and one SDIO.The SPI is triggered every millisecond in a timer ISR and is using two DMA2 streams 0 and 2 in direct mode at a very high priority for TransmitReceive. Then, the D...
I have a STM32F091 Nucleo-64 and have the basic RS232 UART examples (ComPolling and IT) from the Cube working.I need to implement RS485 and was hoping to find a basic example to build upon.I'm currently going through the STM32Cube_FW_F0_V1.9.0 exampl...
Is there any easy way to get to the newest contributions in above thread? It is over 100 entries long and to get to the bottom, where newest contributions reside, requires tedious scrolling, clicking, waiting for reload, scroling, clicking ... etc.Is...
