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...
I want port U-Boot to my own board with stm23f767;Now I stock with FMC Nand Flash driver;there is a MT29F4G08ABADA on my board;when i set FMC nand register,i think this will be ok;but i'm wrong;i still could not get the nand id;when i debug under U-B...
I have not tried, I would need this 'feature':Have a GPIO pin configured as Open Drain output, driven by the MCU. If MCU sets it to high but on the outside an external chip drives it low - could I read the status on the external pin without to change...
STM32F722 Strange GPIO problem with Multiple CD4094(Serial to Parallel Converter)Hi,I am working with GPIO LED , LCD 4-bit Mode Working fine. But 16 Multiple CD4094 have strange problem as below.I am Just using D0, CLK , STB. and Not using any extern...
Hello to everyone,I'm working on the STM32F746NG Discovery Board to realize a simple audio effect and i need to use the audio codec WM8994. It is interfaced with the SAI2 audio peripheral. I dont want to use the HAL libraries but to write directly th...
Hallo,2 STM32 μc (NucleoF767ZI and Nucleo F446RE) should communicate via SPI. The first µc is programmed with Simulink using the Nucleo Support Package. As it stands, the μc with the Support Package can only work as a master. Now I just want to send ...
I want to connect the PF1-OSC_OUT pin to another circuit on my board, to use this 32.768kHz clock for another counter. ( instead of adding another crystal )Would this be a problem? I can buffer it to minimize pulling the crystal. Any suggestions?(I...
I am using #[STM32 MCUs] #Cortex-m0 . In linker file we have symbol: __ICFEDIT_region_ROM_start__ How we can use this symbol in application ?I have assigned &__ICFEDIT_region_ROM_start__ to Pointer.i.e int *p = &__ICFEDIT_region_ROM_start__now usin...
Setting up the MCU to use a PCLK of 32 MHz (using PLL and external 16 MHz xtal in x4/2 mode ) I can confirm the clock is really running at 32 MHz with the USART config. I get the expected baudrates and SystemCoreClock is uppdated correctlu.When I the...
Hello,I would like my STM32 to be able to wake up from sleep / standby by an interrupt caused by input on an analog pin passing a certain threshold (let's say, 2V).Is this an existing capability?How is it called? is there a way to look for this capab...
I want to generate bursts of complimetary PWM to drive a half bridge. I have the PWM working fine, with deatime etc... but when I call:HAL_TIM_PWM_Stop(&htim1,TIM_CHANNEL_1);HAL_TIMEx_PWMN_Stop(&htim1,TIM_CHANNEL_1);Rather than stopping to a defined ...
