Is it recommendation to used internal RCC clock instead of external crystal.
For peripherals like SPI as HCI, I2S which clock should use RCC or external crystal?

Resolved! frequency measurement behavior
Hi,I'm measuring a 40-60Hz frequency range from an input capture timer (STM32L475RCTX TIM4). The result is an expected calculation from 4000 to 6000 (40.00Hz-60.00Hz) using this initialization code:static void MX_TIM4_Init(void) { /* USER CODE BE...
Hi every one, I am using STM32F469 discovery , I just created a project in touchgfx with 2 png background screens and and when I refresh and compile this project in IDE I got errors .
the errors like :\st\stm32cubeide_1.6.1\stm32cubeide\plugins\com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.9-2020-q2-update.win32_1.5.0.202011040924\tools\arm-none-eabi\bin\ld.exe: STM32F469I-DISCO.elf section `ExtFlashSection' will not...
Resolved! About STM32G474 option production value?
My target device is STM32G474VET6. I checked my empty device that the values are the same with "ST production value" from user manual. (Please see the screenshot) After flash programming on this chip(have done erase and program, no options), I read d...
Resolved! question about STM32L562 smartcard mode?
Hi,When I configured the USART to "smartcard with card clock" mode, it can receive the response with 2bit guard time from smart card, but can't receive the response with 1bit guard time.Please advise why it can't receive the response with 1 bit guard...
ECC implementation for SDRAM in STM32H7
Hi team,We are working on project where external SDRAM is interfaced with STM32H7 microcontroller through FMC and its working fine.Now I need to implement ECC for the SDRAM, Can anyone help me out and the process flow to do that and any inbuilt regis...

Hi,Can anyone please provide me the latest I2C application note for the STM32F303 Controller.I had an August 2013 document.Thank You,Vinod Kumar
Dual ADC mode with DMA circular mode problem for STM32L475
In the reference manual, it is showing that for the dual-mode circular mode we need to use the DMA related bits in the ADC12_COMMON -> CCR instead of DMA bits in ADC1 -> CFGR. For me, this DMA transfer in circular mode is working properly only when D...
Resolved! STM32L0 - How do I now how much time the board stayed in standby mode?
I'm working with the SMT32l072 and in my application the board runs the main routine them it stays in standby until the RTC Timer (5 minutes) or the RTC Tamper detection (A sensor that pulls down the pin) wakes the board. The thing is that when the b...
Resolved! STM32L4 UART DMA TX Callback not called
Posted on June 15, 2017 at 13:00 Dear community, I used CubeMX to setup a project for UART DMA transfers RX and TX. Apart from my protocol logic, I added two callbacks: void HAL_UART_RxCpltCallback(UART_HandleTypeDef *UartHandle) { rx_cplt...
