I am using STM32G050 and I also tried with STM32L476. I am transmitting data as an I2C Slave using STM-HAL. However, when I use HAL_I2C_EnableListen_IT, the transmission is an error. I can't read values and see the logic analyzer. HAL_I2C_DisableList...
Hello everyone,I have been struggling with the ETH interface on my board for a while now.Since I'm stuck, I wanted to ask if any of you can help me or give me a tip on which direction to look.I have a customised board with an STM32H743IIK6. The LAN87...
I have an ADC issue with the STM32F0. Looked all through the HAL docs and not sure what the error is. I can't get the ADC to complete a conversion or if it does only the first call. When I debug with the ADC calibration call, it goes to a fault. When...
Hi, I have a firmware runing on STM32F405RGT6 whith is reloacted at 0x800C000 and is called by a bootloader. The problem is if I enable UART DMA, the program will be interrupted by non stopping DMA interrupt immediately. However, there is no stream...
Hi all!uC: STM32L433VCTCubeMX, CubeIDE, CubeProgrammerI've configured my RTC to set an alarm every minute. When an alarm occurs, the next alarm gets set and so on.About once to twice a day, the rtc alarm is skipped, so there's a continous error, beca...
I'm running the board on 3.3v, and as per documentation: +3V3 power supply Using the +3V3 (CN4 pin 14) directly as power input, can be interesting, for instance, in case the 3.3 V is provided by a shield board. In this case the ST-LINK is not powered...
Hello Experts, I designed my custom board with reference to AN5419 application note (Getting started with STM32H723/733, STM32H725/735 and STM32H730 Value Line hardware development). but it doesn't work.When i apply to power to the board and connect ...
Had a look at the newest 'F437/439 datasheet (wonder why 'F427/'F429 was not updated with the same things, e.g. ETH_MII_RXD2 missing in the AF table for PH6):I don't think it was supposed to look like this.JW
I want to execute a program by copying it from flash to RAM on power-up. How can I achieve this?STM32CubeMX's PCC tool as shown in the diagram:
If you put an MCU in sleep mode with WFI, such as the STM32L452, you are supposed to suspend the SysTick and resume it after. Usually this is done in the main thread context. However, when you have an interrupt, I believe the next instruction will be...
