I am designing a system with an STM32 and an FPGA(Xilinx 7 series).STM32 is in charge of the user interface and the FPGA is in charge of driving the LCD to show images.Information needs to be exchanged between the STM32 and the FPGA. (STM32 send a co...
Hi STM Team, We are planning to use STM32G491 MCU in our application. As per datasheet, it is mentioned that STM32G491 MCU will support USB PD 3.0. We have come across the below STM document where it is mentioned that "STM32 UCPD MCUs are compliant ...
Tests Performed and Results:1.A DC regulated power supply was used to provide 14V to the board directly. At room temperature, the CPU's TIM pin output is normal. However, at high temperatures, the output waveform becomes intermittent.2.The on-board ...
Hello,I'm using a specific board where the STM32 cohabit with another "master" device on the parralel bus.One time the STM32 is the master and "drive" the external RAM and one time the other device "drive" this RAM.My first thought was to disable the...
Hi allI am working with SPI1 on stm32f407vgtx and issue what I am, facing my NSS which internally controlled by SPI is taking more time for goes high even CLOCk has been stopped . my configuration are SPI full duplex 16 bit data clock is 2.6MHZ after...
I’m using the STM32L443 in one of my products, and currently, there are around 2,500 units deployed in the field. I’ve been experiencing issues that I believe are related to the firmware programming process during production. The product includes a ...
I'm trying to understand the operation of the STM32F446xx family of microcontrollers. I'm reading the reference manual that's available here: https://www.st.com/resource/en/reference_manual/rm0390-stm32f446xx-advanced-armbased-32bit-mcus-stmicroelect...
Hi everyone,I'm working with an STM32U5 and using USBX with the CDC-ACM class.My setup is as follows:I have a USBX CDC ACM receive thread that calls usbx_cdc_acm_read_thread_entry() in ux_device_cdc_acm.c file.Alongside, I have a state machine runnin...
Hi, I'm searching for more details on STM32F303 ADC Voltage Regulator Function ADVREG. According AN4195 it needs to be enabled before ADC calibration. ADC Regulator is by default disabled. But i cannot see any big difference on ADC conversion result...
... leads to "funny" results:STM32L011 with 16 kB of flash, HAL inits and LED toggle in main, DEBUG, no optimization:93% of flash usedI had not expected it to be that bad! :grinning_face_with_sweat:Okay, I will probably not use too much HAL, will use...
