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, everyone, I have the next problem, I am using the same pins like a simple GPIO output, and like a PWM output.To change the output from PWM to GPIO i using this code: GPIO_InitTypeDef gpio; gpio.Pin = GPIO_PIN_0|GPIO_PIN_1; gp...
I'm using STM32F427.I want to declare the variable as a custom section and use it in a specific address area on the MCU FLASH.I change the *.ld file, declare that the variables are assigned to the designated section, so the compile becomes normal, an...
Hi, our hardware engineer kinda messed up and I'm forced to use an onboard STM32C8T6 and lowball it as a UART "relay", basically UART1 reads whatever that's putting in with likely a buffer of 32 bytes, and immediately sends them out over UART3.The du...
Hello,I'm using an STM32H743-EVAL2 board, I want to access the LCD screen to draw a PNG image, so I'm using a png library to load the image, and this library use "malloc".Unfortunately the RAM of the H743 is too small for handling large pictures, so ...
I'm working with a 24-bit external ADC (LTC2512-24) and stm32u5 (NUCLEO). With the MCU as master, after Data Ready Line (DRL) falling edge from the ADC I need to read 24bits via SPI within 740ns and then have SCK remain quiet until the next DRL falli...
HelloI'm using an STM32L431 and trying to enable character match on usart2MXcube does not manage "MODBUS" modes and the st HAL layer doesn't seem to allow this setting (it allows modbus timout but not character match)So I try to modify USART_CR2 ADD...
Hello I have a custom board with a STM32H753ZIT and I’m wondering about the amplitude of the HSE crystal. It is only 300mV (see the attached Image). It seems to wok but is this normal?The crystal requires a load capacity of 20pF per datasheet, the ca...
Hi,I am doing security project by STM32L562QE and have some questions.1. I am trying to generate SFI file, but I didn't find the document talking about how to generate these files(encryption key file, Nonce file, and option bytes file). Can you provi...
Posted on January 02, 2018 at 22:53I have an application using an STM32F429ZI processor and I'm seeing a strange problem where the L/R audio output gets swapped after changing I2S frequencies.My procedure to change frequencies is as follows:HAL_I2S_...
