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 ATM32H747XI datasheet Table 9 on page 89...As I read this table... Examples are...Pin Name PA1 Alternate Function AF1 = TIM2_CH2Pin Name PA2 Alternate Function AF2 = TIM5_CH3Question 1:For PA0 AF1, there are two functions listed... TIM2_CH1/TI...
Hi community. I would like to know if reading the internal temp of the mcu (using the right channel of the adc) can give you an accurate idea of the temperature of the pcb where the mcu is mounted.Is it accurate this temp?Is it sensistive to other ef...
Hi I have pin PA6 setup to interupt on high and low levels. I have done the following:GPIOA->MODER &= ~GPIO_MODER_MODE6; //PA6 as inputSYSCFG->EXTICR[1] &= ~SYSCFG_EXTICR2_EXTI6; //PA6EXTI->RTSR1 |= EXTI_RTSR1_RT6; //enable rising edgeEXTI->FTSR1 |=...
Hi,I have inherited a project that utilizes Nuttx RTOS. This project is to change out the LCD display due to EoL. We are changing from Renesas R61580 Driver to Ilitek ILI9341. The existing driver is hooked up via 16-bit MCU command via the FSMC, with...
Hi everyone,I am encountering issues in sdcard initialization on my custom board.I am getting SDMMC_FLAG_CTIMEOUT error in SD_PowerON once the first CMD8: SEND_IF_COND is sent.Looking at signals and comparing with an identical custom board, you can s...
Hello,I've seen the AN4229-how-to-implement-a-vocoder-solution note, which talks about support for G.711 and G.726. Does anyone know if anything is available specifically for G.722?Thanks

Dear STM CommunityIn order to ease our debugging, I would like to make use of the Micro Trace Buffer which seems to be integrated in the Cortex M33 Core (e.g. stated by STM here: https://www.st.com/content/st_com/en/arm-32-bit-microcontrollers/arm-co...
Hi,My MCU us stm32f401rct6.This MCU has three UART and all UART are using for service. No console UART port :(So, I make a USB CDC device to use console port.But, iwdg is not working. When I use UART console port, while(1); occur watchdog reset. But,...
