Hello STM32 Community,I'm trying to implement CAN communication on my Nucleo F446RE board and I'm facing some challenges getting it to work properly. I've attached screenshots of my .ioc configuration and the auto-generated code from STM32CubeIDE for...
Hi everyone, I'm trying to generate a sine wave using PWM output updated by GPDMA transfer on an STM32H5 device. I'm following this tutorial:STM32 Change PWM Duty Cycle With DMA For Sine Wave Generation However, when I try to implement it with STM32H...
Can we keep VDD33USB keep NC if USB feature not using In STM32H753ZIT6?If kept NC what may go wrong?
STM32World Rant #2 - MYSTERIOUS UNKNOWN MCUJust a short rant about the MYSTERIOUS STM32F402. This MCU does NOT exist in ST's catalog, and yet you can readily buy them in China. In this video I will go through the datasheet, find a comparable MCU whic...
Hi,I'm looking at implementing USB on my the NUCLEO-64 STM32F303RE EVAL BRD, with of course the STM32F303RE microcontroller. I'm having issues understanding what alternate function is needed for the USB-DM and DP pins. In the datasheet https://www.st...
Hello, I have the following problem - I configured TIM2 of STM32H723 in Encoder Mode following all recommendations in the Reference Manual RM0468, chapter Encoder Interface Mode, p. 1694: • CC1S= 01 (TIMx_CCMR1 register, TI1FP1 mapped on TI1)• CC2S= ...
I am new with the STM32 MCU and this is my first projectI am using a STM32F407VGT6I started a project that read a 16bit parallel on PDx GPIO. The data is placed by an external device and a signal is set to low for 400ns. I connected that signal on PB...
Hi,I used to run my STM32F303RE at 72Mhz clock from a 8Mhz CMOS oscillator. . Timers8/1 operated at 72Mhz as well. That worked fine. I had to change the CMOS oscillator from 8 to 24Mhz.I tried two modifications, see attachment:a) I changed PLLMul fro...
Hey, I just want to report an error in the Reference Manual for the STM32F411xC/E microcontroller.Reference Manual: https://www.st.com/resource/en/reference_manual/rm0383-stm32f411xce-advanced-armbased-32bit-mcus-stmicroelectronics.pdfPublished on: h...
Hi all.I have this piece of code: __HAL_RCC_CORDIC_CLK_ENABLE(); CORDIC->CSR |= CORDIC_CSR_NARGS; CORDIC->CSR |= (CORDIC_CSR_PRECISION_3 | CORDIC_CSR_PRECISION_2 | CORDIC_CSR_PRECISION_1 | CORDIC_CSR_PRECISION_0); CORDIC->CSR |= CORDIC_CSR_FUNC_1...
