Hello// nucleu-h745zi-qI want to use hardware flow control rs485Previously, i used an external module because there was only rs232 (f103).** question ** . With this feature, can the module be removed and the microcontroller directly connected to A ...
To enable LwIP in CubeMX (inside CubeIDE) it needs the CPU data cache enabled. Ok, no problems, but it doesn't explain why and I can't find why this is the case. Is anyone able to offer an explaination?
I am trying to interface a 7" LCD-TFT screen that uses LVDS for its interface. I was wondering if the LTDC on the STM32F439 or STM32F469 could be used with the LVDS interface?
Hi ST, Can I request the MISRA compliance report for STM32H747? Or where can we download the relevant document? Thank you.
Hello,I have developed my own board using the STM32H723VG and two equal sensors connected separately via SPI1 and SPI2.I have underclocked the MCU to 300MHz. The SPI clock is 48MHz while the communication frequency for both sensors is 24MHz. As CS I ...
I need to use the energy collection mode of ST25 to wake up L4. The software used now is En.X-Cub-NFC7. How can I modify the example code to set L4 to low power mode and wake up L4 only through the energy of ST25?
i have established communication with a BLDC (Brushless DC) controller. Initially, i send a message to the controller using the function void sendParameter(uint8_t parameter). Following this transmission, the BLDC controller is expected to respond w...
Hi there,I received a new out of the box NUCLEO-144 H723ZG board which I can not connect, but getting the "Can not connect to the target!" message (see below)What I've done so far:- checked the Jumper as described in user manual UM2407 section 5 >> a...
Hi,I am using LPUART and LPDMA on STM32U575. But I am getting Data Transfer Error.I have tried LPUART with GPDMA it works fine but LPUART with LPDMA giving Data Transfer Error.So I have two questions:1. Can we use LPUART & LPDMA together?2. What will...
I am trying to set up a multichannel ADC and following YouTube tutorials to create it. However, the STM32 IDE will not allow me to set preemption priority to 1. Similarly, I cannot set the clock prescaler as divided by 2. I need to make a multichann...
