I have RS-485 transceiver connected to USART1 (PA9 + PA10) and relay connected to PB4. If MCU have erased FLASH or RST-pin connected to GND all incoming data to pin PA10 (Rx) for RS-485 line translated to pin PB4 in inversion (0 on PA10 => 1 on PB4, ...
I purchased a new STM32F407G-DISC1 (MB 997D) board last week. As shown in many of the videos, I am not able to program it using STM32CubeIDE. Tried with ST-Link utility & STM32CubeProgrammer as well but no luck. I observed target voltage is detected ...
STM32L412xx datasheet DS12469 even in Rev. 8 talks about � Accurate 2.5 V or 2.048 V reference voltage buffered outputon the front page. The reference manual gives only availability on L43 and L45.
Hello, I am trying to set the UART5 TX with the DMA. I am using Cube, and in the GUI I selected UART5 to asynchronous, and added DMA for UART5_TX. Then, in the generated code, I added this part as I didn't see initialization for the DMA (inside the M...
Hello,Many times i get into problems that I should not get into, like simple logical mistakes while executing code:examples:uint32_t a = 1; if(a==1) { MCU goes here, it's how it should be; } else { MCU goes also here , how is this possible?; }M...
I'm currently using the STM32 L476RG for an application where I need to communicate with peripherals through SPI at 1.8V. Currently I'm using the TXB0108 bidirectional logic level shifter to convert my SPI lines from 3.3V to 1.8V but there are proble...
Dear friends, I need your help with the issue of data corruption when reading the data on SPI bus in STM32F407. I'm using 24 channels of temperature measurement (slaves) with one master STM32F407. 12 channels are connected to SPI1, other 12 channels ...
I've had some success getting UARTs to work on a Nucleo 413ZH board but am struggling to get the same code working on a Nucleo H7A3ZI-Q board. I have a logic analyzer connected to the TX and RX pins on the Nucleo boards. The HAL_UART_Transmit line (l...
Hello,I want to be able to do multiple routines in my stm32 code. I went for the option to use Switch case statements. The problem is after the code has done one iteration the variable that is used in the switch statement(routine_test) changes on its...
