Hi guys, I'm having this issue where I kept getting a Transfer Error when setting up a DMA.One of the replies I got is that DMA1 can't reach the memory area of DTCM, which would explain why it can't transfer the context from the buffer into the peri ...
I'm trying to connect a quadrature encoder to my board using STM32L4R5. From what I understand, I should connect the A and B to TIM2, TIM3, TIM4 or TIM5. If I have 2 encoders, can I connect all 4 A and B signals from both encoders to the same TIM? Li...
Currently I am using the STM32H753ZIT6 to do all the bare metals. Essentially what I am trying to do is just enable UART4 Tx to send some debug messages thats all. Everytime I try to enable the DMA1_Stream3 (UART4_Tx) it just gives me a TEIF3 error a...
Hi all:I am using an STM32407 running at 3.3V, and I have 2 inputs connected to 5V signals.One of the signals comes from an outside sensor (a data line), and the other one is connected to a 5V optocoupler populated on the same board.I have measured t...
Is this part not for new designs? We are prototyping on the nucleo which uses the same chip.https://www.digikey.com/en/products/detail/stmicroelectronics/STM32F303K8T6/5268259
I am having a hard time finding out the state of the UART pins while the chip is held in RESET. Are pins E2, D5, D4, and E1 held in a high-impedance state while the RESET pin H9 is pulled low? I suspect they are, but am trying to confirm through docu...

Hi,i come up with my question related to I2C communication using stm32F103,I would like to interface my I2C LCD (slave) with MCU ( master), but i have a problem with the Transmit sequencei have configured the GPIO's PB6 (SCL) and PB7(SDA) as open dra...
I have the STM32F302R8 board and I have this problem.The clock is at default 8 Mhz.TIM2 is configured with toggle output CH1 on PA0. (This works fine).TIM15 is configured as input capture CH1 on PA2.I have a jumper between PA0 and PA2.The aim is that...
Hi, I have a custom container that includes a digital clock. But when I set the clock any initial time, it starts from 00:00:00. How do I set the clock to the initial time that I want?
