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?
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...
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...
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,
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
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) ...
Hi,Master:Platform: STM32F301K8UAs shown below in Figure 1, PA7 (MCU_14) is a video signal (As shown below in Figure 2), which contains the line sync signal (A area in Figure 2, fixed frequency, there may be noise)and the field sync signal(B area...
