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...
Hello.First of all, thank you for your help.I have a question about UART & debug.When I stop transmitting from the PC while communicating with the PC and then debug, there is no problem.When I stop debugging and resume while transmitting from the PC,...
I'm using UART7 on a STM32H743 to drive a RS-485 transceiver. I've set it up to use the hardware DE pin to switch the transceiver between TX and RX modes. I transmit 14byte messages to devices on the bus, and they send back ~14byte messages. My code ...
I am trying to implement an application with USB CDC-ECM host capabilities. As a bring up setup, I configured two STM32 boards:1) STM32U5G9J-DK2 board, configured as a CDC-ECM device, using USBX.2) STM32U575I-EV, configured as a CDC-ECM host, using U...
