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...
hello forumI've been playing with a H747I-Discovery board, and I want to add some more functionality to a combination of example codes - activating one of the i2c.the example itself doesn't include an .IOC file.As I see it I have two options:1.Start ...
Hi @Tesla DeLorean ,I use the IS25LX064 OctoSPI Flash memory with the STM32H573 and i can write and read from memory using direct mode. In memory mapped mode i can read the flash correctly for 0x90000000 but writing at 0x90000000 using memory mapped ...
(Spotted by sx107.)I know the subject is not very descriptive, but a figure is worth 1000 words:It's also in other 'H7 RMs; I leave it to ST to check them all (Btw. this is a carryover from the 'F7 RM, where both OTG's SOF indeed feed into TIM2 ITR1,...
TLDR: application tried to write to a FLASH address without accessing FLASH peripheral, so the Flash bit CFGBSY in the SR register got set and further accesses to FLASH CR register leads to a Bus Error (not documented). Of course, the main action is ...
Hello,I am using the Nucleo-H767ZI board. On this board, I am working with both a version that uses an external oscillator and one that does not. My question is whether it is normal for the firmware to work regardless of the following settings: RCC_O...
Posted on October 22, 2016 at 04:27 I am not sure if this is a bug fix or an enhancement. I am developing on a proprietary board using the STM32F7 series processor. I have a device connected via USB using the USB Host Library. This particu...
I am a beginner using the Nucleo-F334R8 with Keil and STM32CubeMX.I want to read ADC data with DAC. The ADC is from a potentiometer, and I will read the DAC using an oscilloscope. I am using the program below so that when I run it, it will generate t...
HiI use STM32U575I-EV.I want to periodically read data from an external SPI device without CPU.The SPI device will emit a data ready signal(active low gpio), so I want to use that as a trigger to read the data.Ideally, I would like to perform multipl...
Hi,i'm using a STM32L031. In my code i first initialize the MCU (FLASH, CLOCK, INTERRUPTs, GPIOs), start the LPTIM (running on LSI), then slow down the MSI clock, start the timer22 for PWM and go into low-power sleep mode. When i let the program run...
I'm currently testing low-power applications on the NUCLEO-U545RE-Q board, which involves using an SSD1306 OLED display and a BME280 MEMS atmospheric sensor, both interfaced via I2C1 and I2C3 at 1 MHz. The FCLK is configured to 160MHz. Clock source i...
