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,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_...
HelloI have interfaced sd card with controller STM32F779BIi have write text file in sd card but i could not see at what time file is written to sd card doesn't show in properties of that text fileis this is possible , if yes then how can i do that ?B...
Hello everyone,I'm trying to debug a problem with the UART communication between the raspberry pi 4 and an STM32.Indeed, I try to send the number 1 from the raspberry pi to the stm32 but I can't get the right result.Here is the code I implemented on ...
Interface of STM32L476RG to TI CC1200 SPI. Using MCU registers with NSS produces short acceptable CSN to clock start interval but I cannot get rid of the high pulse between frames which causes the CC1200 to malfunction. Manually configuring and toggl...
I have a nucleo-f767zi. When I connect it to my Linux computer by USB cable, LD4 keeps blinking red slowly and LD6 goes to solid green. And it stays there forever. I checked in the document LD4 should go to blinking red quickly then solid red. Can yo...
