STM32 MCUs Products

We currently use Original: STM32F423ZHJ6 Proposed: STM32F413ZHJ6 There are 2 PWM in STM32F423ZHJ6. There are 4 PWM in STM32F413ZHJ6. Are there any other key differences? I vaguely recall a difference in the encryption. Difference between 413 & 423

ST, in models with VREFBUF, don't call its output VREF_OUT

 As usually, I did not check all DS so it may be more widespread.Note, that there are families without VREFBUF but with "genuine" VREF_OUT ('L0/'L1) which behaves differently. Please maintain consistent nomenclature to avoid confusion.JW

RTC ALLARM A and B selected

Hi, i have a problem with my Hardware Flow Control on my STM32F103RBT6. I send a UART Signal with Polling but the STM neither sets the Signal on the USART Tx Pin nor does it set the RTS Pin. Please help me to find a solution. Thank you!

The STM does send the Signal if i set the RTS Pin on high level per software:USART2->CR3 |= 0x0100; //RTSE->1The Problem is i use a three state Buffer Line Driver (74HC126D) in order to enable transmitting or receiving but the RTS Pin from the STM is...

I need design "CAD" resources for STM32F205

Hello,Recently I moved a design to the STM32L552 because I wanted an extra layer of security and protection for my IP. Also, the device has some new features that I plan to adopt in the new design, like the DMAMUX. On the other hand, it's been a whil...

Resetting CNDTR for UART DMA method

I'd like to set the counter of huart2.hdmarx->Instance->CNDTR;To reset the buffer index.How is this done?nevermind. The peripheral required disabling first it seems.huart2.hdmarx->Instance->CCR &= ~DMA_CCR_EN; // disablehuart2.hdmarx->Instance->CNDTR...

STM32 always send CAN data frame

I try tu send CAN REMOTE RTR frame but MCU always send DATA FRAME txtype.RTR = CAN_RTR_REMOTE; txtype.IDE=CAN_ID_STD; txtype.DLC=0; HAL_CAN_AddTxMessage(&hcan, &txtype, txData, &TxMailbox);result 0x022;0; not 0x022;Remote ...

Control multiple STM32 simultaneusly

Goodmorning,I am tying to understand the following case:I've got two STM32F4 both connected to a usb hub, this hub is then connected to my pc. Is there a way to select the micro in which I need to load my firmware? I am not able to solve this out.Tha...
