Hello,I'm currently working on a project where my STM32G747RE is acting as an SPI Slave.The SPI transmission is as follow:Master sends 8 bits "command"Slave send back 16 bits "data"My issue is the following; On the MISO line, the STM32 always send ba...
Hi allI am using 4 sensors on my project. These are comminicated with stm32f4 board via I2C. However there ara 3 I2C channel on stm32f4 board. Is it possible to connect them to same channel via ı2c multiplexer ? As ı researched, the multiplexer is u...
Dear Mr. or Ms.When I tried to clear IT flag of USART_ISR_RXNE_RXFNE, I can't find any fuction to do it.In stm32g4xxx_ll_usart.h, I can find fuction named LL_USART_IsActiveFlag_RXNE_RXFNE() but there's no function like LL_USART_ClearFlag_RXNE_RXFNE()...
Hello everyone,I've been looking for some time for an example of an electronic design that would allow me to use the STLINK-V3MINIE in JTAG mode.With my electronic schematic I can use it in SWD mode, which works very well.However, it's impossible to ...
Dear Sir's, what is the minimum high level threshold voltage for a non FT_C port? Is it 0.7xVDD or 0.49xVDD+0.26? Regards,Jochen
Hi,I need help on MMC operations.My project is using STM32U575 to access MMC chip (EMMC16G-IB29). It uses SDMMC1 on 4B bus (MMC 4bit wide bus). The U575 is running on 90MHz. The initialization sub is: static void MX_SDMMC1_MMC_Init(void){hmmc1.Insta...
Hello,We are using a hardware with STM32H745 controller with FreeRTOS.Can you please suggest a good PC Emulator which can be used to emulate above controller with FreeRTOS.Also we use UART, SPI, LED, CAN peripherals on the actual hardware. Can these ...
Hello,I'm trying to read some data using the RX mode of the SPI emulator explained in AN4678 but I have a weird bug that I don't know how to fix.To quickly explain how it works, the SPI emulator uses TIM1 pin to generate a clock and a GPIO pin to beh...
