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...
Average life of an STM32 microcontroller.
Hi, someone can tell me how much is the average life of an STM32 MCU. If I take an STM32 MCU that performs even a very simple task, and I keep it running 24 hours per day 365 days per year, after how long could I have problems? 1 year? 2 year? 10 yea...
Delay in processing the external GPIO interrupts
I am using the STM32 GO71RB for motor control, My objective is to calculate the position of the motor while its running. I am trying to find the forward/reverse position of the motor using the encoder feedback; the encoder I am using is HEDS-550.For ...
Resolved! Hi team! I am working on the OLED interfacing with STM32F103C8T6. All I want to do that is to display the counter value from 0 to 255 on OLED. But when I simply put the random number such as 48 it shows its equivalent ASCII value not a decimal value.
