Hi guys ! I’m in a bit of a pickle so I finally decided to ask ..I’m using a Dragino sensor node based on STM32. I need to change the default software to be able to read an I2C pressure WNK sensor. I know the sensor’s address is 0x6D. I also know tha...
Hello,We access FMC PSRAM in 32-bits.We noticed that although the access was expected to be in 32-bits (using HAL_SRAM_Read_32b) , CS signal is actually asserted for long of 64-bits!Is there anything which can explain why the CS is twice the time of ...
Sir I want to analysis the audio characteristics for my project using I2S protocol so please recommend me the right board for it and please provide me the proper resources for it.
Well, I use STM32 Nucleo F429Zi and Stm32 Cube IDE v. 1.0.2. I connected SmartCard and STM32 correctly (my oscilloscope shows rigth values of RST, IO and CLK) but in code i see zero filled buffer each SET/RESET iteration where ATR should be. Here's s...
Hi all,i tested two method of I2C transmit and resulted as follow.Method 1 : HAL_I2C_Master_Transmit_DMA(&hi2c1, 0x4E, &Data_M[0], 4); Nothing come out at the logic analyserMethod 2 : HAL_I2C_Master_Transmit(&hi2c1, 0x4E, &Data_M[0], 4,1000); Data co...
I'm using STM32F103RBT6 to connetc to a OLED with I2C1.The init code is as below.static void MX_I2C1_Init(void) { /* USER CODE BEGIN I2C1_Init 0 */ /* USER CODE END I2C1_Init 0 */ LL_I2C_InitTypeDef I2C_InitStruct = {0}; LL_GPIO_Init...
Hi there,We are designing in the STM32H753 and would like to use the factory DFU bootloader. We are able to use the bootloader on the H743 nucleo board, but on our PCB it fails to complete any actions giving a "connection to the target" lost error in...
Hello,We are developing on STM32F427VI . We would like to communicate between the STM32F427VI and with SPBTLE-1S bluetooth device. Can we write an application on the STM32F427 to communicate with the bluetooth device without having to write an applic...
Hello, I am new about MQTT, so I am looking for an example of Mqtt client application using the LWIP MQTT api over STM3210c board with no Rtos support .Can someone help me?
