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'm trying to change color of a component (circle) inside a container inside a scrollWheel.This should occur when user press a button. The button is a component outside of scrollWheel. How can I reach this circle (inside a container inside a scro...
Greetings!I have "blue pil" stm32f103c8t6 and I want to send data over I2C via DMA. "Classic" way is working fine (I'm sending data to 2004 display through PCF8574 extender), but I can't get it working with DMA.BTF flag isn't set and the loop becomes...
I have multiple CAN FD Participant which are configured the same way:if (canFdMode == canFdModes_2mbit) { hfdcan1.Instance = FDCAN1; hfdcan1.Init.ClockDivider = FDCAN_CLOCK_DIV1; hfdcan1.Init.FrameFormat = FDCAN_FRAME_FD_BRS; hfdcan1.Init.Mod...
I want to use a different PLL block than PLL1 to leave PLL1 specific to SYSCLK generation; and for example use PLL2 to generate my arbitrary clock.I see that SAI blocks use for example PLL2 or PLL3 but I don't know if it is possible to make an arbitr...
I am using an STM32L552ZE (it is in fact the nucleo version). After carefully reading the manual and looking at some example code from the STM32 Cube IDE, I came to the conclusion that this code is what I need to enter stop 2 mode with Wait For Event...
Hi All,I am using the simplest mode, single conv, software start, etc. 21MHz clock (/2 divisor).I have been measuring the conversion times both in a loop and with a scope on a waggled GPIO pin.With a sampling interval of 3,56,480 I see conversion tim...
I'm working on a STM32L072, and I want to implement an update over the air. I saw there is an errata about the dual bank boot, and ST has made a workaround on it, and it uses the EEPROM.Code from the errata sheet:void SystemInit(void) { /* ...
In CubeMX 5.3.0 I have configured FATFS and FREERTOS for a card running STM32L431. The HAL SDMMC driver is communicating with SD card, and everything goes well until the FATFS want to read the MBR block from the SD card. In this case, the DMA channel...
