NUCLEO-64 STM32L476RGSTM32CubeIDE 1.10.1 Trying to get a microsecond delay to work based on this post.APB1 Timer = 80 MHz from HSI->PLLCLK.TIM6 = 1 MHz (Prescaler = 79, ARR = 0xFFFF)My main (after MX stuff) looks like this and sets delay to 5000 us (...
Hi there, I am trying to implement 3 CDC interfaces over USB. I'm using the USB stack generated by CubeMX, I enabled composite devices and call 3 times "USBD_RegisterClassComposite" in my "MX_USB_Device_Init".I am having troubles with endpoint number...
I am using the STM32H743VIT6 LQFP100. I am integrating it into a custom board and looking for the best (easiest, cheapest, fastest) way to program it. This will be in a setting where we would like to just plug in a programmer and hit program; however...
Hello, please mention RCC_BDCR_LSESYSEN in U0 reference manual in the LCD chapter. This is a new requirement when running LCD with LSE on STM32U series. Maybe chapter with other devices to run on LSE clock will profite too. Regards
Hello STM32 Community,I’m encountering an issue with the RTC on my STM32L4 microcontroller. When I connect VDD to the VBAT pin (without using a battery), the RTC is not functioning. However, if I use a battery for VBAT, the RTC works fine.Here’s the ...
Hello, I am a developer and I am using the L431RC chip on a custom board. I am using CAN BUS to communicate with the system, and during normal operation (via firmware), there are no communication issues,in fact, everything works quite well. However, ...
Hi folks, I am trying to interface Datai motor control unit for one of my projects using stm32f469I disc board. I am sending and recieving same CAN ID but unit is not giving data in live expression in stmcubeide. Can anyone tell me the solution of th...

Hi,I am using STM32G0B1CBT3 controller and would like to send and receive data in classic mode. I have configured all necessary parameters using cubemx but the buffer is getting full when I call this function HAL_FDCAN_AddMessageToTxFifoQ(&hfdcan1, &...
Hello, I am trying to vary the PWM frequency of Timer 2 in between 20Khz to 200 Khz in stm32G0C1RET6 Board.1. Whenever I change the Frequency from 200 Khz to 20 Khz, it works. but then I change it again to 200Khz it just doesn't work. my PWM line goe...
