I use X-NUCLEO-NFC08A1 on the X-NUCLEO-LG746RG,and the sample program downloaded from the official website to detect the result of UID: F60F7FE3, but I don't know how to analyze this signal. Which specification table should I read to help me understa...
HiI have develop a custom board wit stm32F799 cpu, there is External Quad flash model MT25QL128ABB1ESE 128Mbit 16Mbyte.My problem thar the falsh erase only half size, the address in memory map shall be 0x90000000 to 0x90FFFFFF but the erase work unti...
For some reason HAL_SPI_STATE remains busy forever after executing HAL_SPI_Receive_DMA. This happen for the SPI slave of SPI #2 of the STM32H745XI board. The problem goes away when I change the SPI mode from slave to master, but that's not a proper w...
Hi,I am trying to interface a signal with one of the ADC pins of the STM32F103 MCU. When the signal was scoped using an oscilloscope, it was seen that a noise component was added to the original signal from the MCU side. I have attached images of the...
As described.I am using the B-U585I-IOT02A Discovery development kit. Just testing basic SPI operation and trying to use all three SPI lines.Using basic setup with STM Cube ID I can send data using HAL_SPITransmit over SPI1 and SPI2. Trying to do the...
Hello All.I wrote a simple code, which is supposed to start on reset address, check the availability of an application on the higher application address and jump to it. I am using IAR9.32. The code works if loaded using STLINK but gets into hard fa...
Hello,I’m wondering if there is a solution to expand the flash memory of the STM32WLEx. I have noticed that the microcontroller do not the Quad-SPI interface. Is there any other possibility to see the external memory as memory mapped?Any suggestion i...
Hello everyone!I use the Quad SPI flash of stm32 h750. I write data at a certain address through commands, such as address 0. But after configuring the memory mapping mode, I check that the data at address 0x90000000 is 0x88, while my data is at 0x90...
Dear everyone,I'm trying to manage a DC motor with IC controller in PWM.My frequency have been calculated for have 12bits resolutions (Fclk :72Mhz > Fpwm17.5Khz). TIM2->CCR1 = 30; HAL_TIM_PWM_Start(&htim2, TIM_CHANNEL_1); HAL_GPIO_WritePin(GPIOB, MA_...
Hi all,I am using a Nucleo F334R8 STM32Cube FW_F3 V1.11.4I am trying to configure it as a slave device using interrupts , I am using HAL_I2C_AddrCallback()then it checks if dirrection == I2C_DIRECTION_TRANSMIT and HAL_I2C_Slave_Seq_Receive_IT() wor...
