Resolved! CAN wrong bit timing: bit time larger than expected
Title edited to give an accurate idea of the issue. Hello together, i had a problem with setting a correct bit time on a CAN-port. On my nucleo-h755ZI-Q board, I want to operate the FDCAN1 by the CM4 in classic-can mode with a baud rate of 1 MHz. I s...
Resolved! Can STM32H563VIT6 LQFP100 package support parallel 8080 type LCD interface on FMC?
We would like to connect LCD panel with parallel 8080 type LCD interface. The pin can be setup as follows. LCD_CS --- FMC_NE1 LCD_RD --- FMC_NOE LCD_RW --- FMC_NWE LCD_ReadResistor -- FMC_A16 LCD_D[0:15] --- FMC_D[0:15]/AD[0:15]If the FMC_A16...
Resolved! can I flash 90kb .text hex into a 128kb dual bank stm32G474 dirrectly?
himy Hex file have a 90kB .text session size,and I want to flash it into stm32G474cbtx mcu which have 128kb dual bank flash. I use stm32cubeProgrammer v2.19.0 and stm32CubeIDE v1.19.0. if the option byte DBANK is 1, I can successfully flash it usin...
HRTIM Start Synchronization
Hi All. So, I'm currently working on a project that I need some assistance with... I'm using the HRTimer and ADC. Timer A and Timer E both control my gate drive outputs; they're variable frequency. I also have Timer F, which controls my ADC sampling....
Resolved! Bad voltage on VREF+ pin (VDD instead of VREFBUF)
I'm using an STM32H743VIT6 (rev V in LQFP100 package), powered at 3.3V and programmed with STM32CubeIDE.I'm using the ADC2 and ADC3, and also want to use the VREFBUF voltage (available on VREF+ pin) programmed for 2.5V. The *.ioc file is generated wi...
Should I add an RC filter to the analog input pin (STM32F103 ADC) for a triac light dimmer application?
I'm designing a custom PCB using an STM32F103 microcontroller to control a triac-based light dimmer. The firing angle for the triac is determined by reading the voltage from the potentiometer.The potentiometer output is routed through a header and th...
Can't erase external flash sector on a B-U585I-IOT02A board with STM32CubeIDE functions.
I'm trying unsuccessfully to erase a 4K sector at 0x73ff0000 using STM32CubeIDE code, but the STM32CubeProgrammer works fine. I've tried using BSP_OSPI_NOR_Erase_Block() and MX25LM51245G_BlockErase() with no luck. My code base is the HTTP_IOT_WebSer...
Resolved! Has ChatGPT bricked my NUCLEO-L433RC-P board :(
I wanted to do a full chip erase using STM32Programmer (I am trying to debug a custom bootloader) but kept getting the error "Mass erase operation failed. Please verify flash protection".I sent the following option byte screenshot to ChatGPT....Chat...
STM32F446RET6 Timer and clock
Hi, I designed the us and ms delay functions using timer 2 and 4. Initially in the PLL source, I was using HSI, but it had some errors, so I switched it to HSE. I was using my delay function to control the DAC output, but when I switched to HSE, all...
