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) ...
Resolved! Questions about this circuit and a solution
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...
Reading data from external ADC chip using GPIOC port and DMA2, does not work as espected.
Hello.I am trying to read data from a 12bit ADC AD9226 connected to port GPIOC, on STM32F407VGT6 clocked at 168MHz. On port PA8 there is a 42MHz clock for the external ADCand also the same TIM1_CH1 I triggers the DMA2 to transfer data from pheripher...
STM32H750VB SPI Slave MISO last bit returns low to early
Hi there,I am using the STM32H750VB as an SPI Slave in Interrupt mode and it is working but I am not happy with what I see with my analyzer.SPI is working with Idle-Clock Low and aquiring data at leading edge. LSB first.That's all how it should be bu...
