Resolved! Nucleo F401RE Usart Tx Blink Led
I have Nucleo F401RE board.I want to Turn On Led When Usart Tx pin high and Turn Off When Usart Tx pin is low./* Private user code ---------------------------------------------------------*/ /* USER CODE BEGIN 0 */ uint8_t data_tx[5] = {0x41 , 0x42 ,...
Can't connect using the I2C Bridge and the ISB042GUI "it's not possible to read the device mode information"
Hi, I'm having trouble with the ISB042V1 evaluation board and the I2C bridge dongle. I believe I have everything wired correctly, but I get an error message when I press the "Connect I2C Bridge" button on the GUI.I have provided 5V power to J2 as in...

How PDMS bonded to SU8 that covers microfabricated gold electrodes affect their electrochemical activity?
We microfabricated gold electrodes and coated them with SU8. However, when we bonded PDMS onto the SU8, the electrochemical activity of the electrodes dramatically decreased. Any ideas what could be the reason?
Send UART hex command
HiI'm trying use DFR0534 with STM32f446.This module read uart command hex.Ex. Command AA 07 02 00 08 BBIm trying send like thischar play[6] = {0xAA, 0x07, 0x02, 0x00, 0x08, 0xBB}; HAL_UART_Transmit_IT(&huart4, play, 6);But in uart monitor recive diff...
Resolved! STM32F446RE Can't use Pins PA2, PA3 as Input
Hi,I am trying to use the PA2 and PA3 Pins among others as Inputs with Pullups. The configuration is correct, since I am comparing what is in the GPIO Registers for Port A with another input pin PA8 which works fine. I have seen that the same pins us...
Accessing Timer OC register for DMA transfer.
Hi All,I'm using a STM32F302R8 and want to transfer timer 2 capture/compare values to memory using DMA. What source address do I use for the TIM2 OC register? I'm calling HAL_DMA_Start() to do this and need the source address of TIM2->OR.Thanks,
Resolved! STM32H753 vs STM32H743: Can I substitute?
I need to get some PCBs made by JLC but they are continually out of stock of the STM32H743IIT6 which is my target processor. They do however have the STM32H753IIT6. Is there any reason I can't substitute these to run identical firmware?Thanks
Pins connection SWD st-link to an external STM32F103RBT6
Hi!I'm trying to use my ST_linkV2 debugger to program an external STM32 microcontroller using SWD, is this configuration ok ?: CN4 (STLlink) Vdd----------> Vdd (stm32 MCU) SWCLK------> PA14 (SWCLK) ...
