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 Guys,Quick question. We are using STM32H757Eval board for an application. We are not using in-built DSI display, instead, we use RGB display of size 1024*768. We are using 32bpp and transmitting RGB via LTDC. As per the datasheet, the maximum perm...
I'm currently trying to get a message from another can device and I can't figure out why my callback isn't triggering.I can transmit a message without any problem however I can't receive any. I am using vector CANalyzer to check my bus.I was trying t...
Hello everyone, I am trying to measure how much time is used to finish executing a function. I cannot use the timers because it adds some delay to the system. My other option is to use GPIO pins.To do this, ISET a pin at the start of the functionRESE...
I'm using the HAL_I2C_Master_Transmit_DMA driver on an STM32L412. I am transmitting 8 bytes of data to an external 4 channel I2C DAC - I have only one device on the bus. The first use of the driver works fine as confirmed by using an oscilloscope on ...
Hello ST community,I have QSPI flash and an environment sensor based on SPI with stm32l496rg development board.If I put controller in stop mode 2 without sensor and flash current consumption of system is 3uA.If I connect flash and sensor then in stop...

Hello community,I have a problem with using usart6, although usart1 is working fine.My setup: STM32F439, usarts connected to a dual ftdi chip, so I have two com ports on the pc to choose of, which represent usart 1 on usart 6 resp.Also direct usb con...
please review the datasheet,--4 Pinouts and pin descriptions-- from the datasheet, both PIN 42/43 and 45/46 could be I2C1; both PIN 21/22 and 35/36 could be I2C2; which is right exactly?
Hello,I am measuring execution time of a function that operates with floating point numbers and noticed that it is more than I expect. I am using Nucleo F429ZI, clock is configured to the 50 MHz. For measuring the execution time I use TIM6 configured...
