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 an electronic engineer and I'm working on a project for automation of agricultural machinery, we are using in this project the microcontroller STM32F446RCT7TR. however I have little experience in this microcontroller and so I'm sorry if my...
I'm planning on using a STM32F411CE in an application where the SDIO hard peripheral is connected to a SD-card in 4-bit mode. I also need to use both PA and PB ports in a rather high-speed fashion, so I'd like to set them one 16-bit word at a time (i...
IN the rm0316 documentation, there is no explicit indication of where and which SPI interface takes the clock, you have to "guess through who turns on this periphery", which is not "strictly deterministic behavior". the documentation is done formally...
HiI'm trying to read an EEPROM connected to SPI1 and facing difficulties. For some reason the clock is off by being idle high. This doesn't happen if I use SPI3 and am therefore wondering if there's some characteristic or further configuration that i...
hey thereI am using an EEPROM which is AT24C08. here is my code //write ee24_write((16*(3)),(unsigned char *)("+989163306941"),13,500); ee24_write((16*(4)),(unsigned char *)("aaa"),strlen("aaa"),100); ee24_write((16*(7)),(unsigned char *)("+989163...
I could successfully build (with STM23CubeIDE) and run these projects:STM32CubeF4\Projects\STM324xG_EVAL\Applications\mbedTLS\SSL_ClientSTM32CubeF4\Projects\STM324xG_EVAL\Examples\UART\UART_PrintfAs a next step I wanted to send out debug messages on ...
I have a ST32F769I-DISCO board and an example project that uses the onboard ST LINK/v2as a VCP (Virtual Com Port) that allows me to use printf to send data to a terminal on the PC.This example project is not a CubeIDE project and all hardware setting...
Hi All, I've created a PCB (same happens on the Open107V dev board) and I'm finding that the I2C comms is failing unless I have an external capacitor of 22pf connected from the SDA line to ground. I know the aim is to keep the capacitance as low as ...
Hey guys and gals! I am facing a persistent problems when configuring system clock on the STM32L152 to 32MHz using SPL. It smoothly runs at 24MHz but always freezes when making it to run at its maximum freq.The MCU's max clock frequnecy is 32MHz and ...
Hi,I am trying to post an issue and getting "Looks like you don’t have access to create a case. Ask your community manager for access"Can you please give me access.ThanksSharon
