Olá pessoal, estou tentando atualizar o micro firmware usando stm32 cubeIde stm32l072kztx. Já tentei usar os comandos AT^SISS e baixar o arquivo .HEX compilado via FTP, já tentei usar os comandos AT^SNFOTA, mas não funcionou. Baixando via FTP consigo...
Hi,I want to use input capture mode using TIMER2 feature of Stm32f730vbt6 microcontroller. I am receiving a pulse signal from the oscilloscope and I want to remove it via STM using the timer's input capture mode. What should I use in the code for thi...
I am trying to implement LCD and AMS5812 Sensor on I2C3 Bus,But AMS5812 I2C sensor is holding the I2C bus and preventing further scanning STM32F407G Discovery board. /*-[ I2C Bus Scanning ]-*/ HAL_UART_Transmit(&huart2, (uint8_t *)StartMSG, s...
Hello,I am going through the datasheet for SPC58EEx, SPC58NEx , I want to know which HSM module does both of the MCU support is it HSM Low, HSM Lite, HSM Full or HSM medium?Also want to know if both have MCAL support
Hi there, i come across AN4760 p55, configuring GPIOB with alternate functions :GPIOB->AFR[0] = 0x0A000900; where does this 0A000900 come to config PB2 n PB6 to QSPI alternate function?GPIOB->AFR[1] = 0x00000000; ....GPIOF->AFR[0] |= 0x9900000000; ...
Hi everyone, I meet a problem and I'm not sure it's MCU issue or I program not proper.I meet this issue both on the STM8 and STM32 MCUs.I enable TIM_2 Ch1 as input to capture the signal and TIM_2 Ch2 as output to do the compare function. void init_TI...
Hi,I'm using USART with DMA to transmit a fixed sized packet message from master to slave, and have the slave send back a fixed size response. I have a freeRTOS enabled. I have DMA setup in circular mode, and set the buffer size to twice the size ...
Hello, I got a problem on 'HAL_UART_Transmit' function. I wrote a simple line to create and define unsigned char of 10 then send it through 'HAL_UART_Transmit' on different .c file.unsigned char A[10] = { ...... 10 value ......};HAL_UART_Transmit(&hu...
Hello, I am creating a sensor using the STM32F401RCT6 and eight SPI ADCs. Because the MCU doesn't have that many SPI ports, I am planning on adding a 3 to 8 decoder in order to handle the Hardware Slave Select (NSS) of the ADCs and daisy chaining the...
After inspecting blocking I2C functions from HAL libraries I found that apparently I2C blocking functions don't return "HAL_TIMEOUT" status if timeout is reached during I2C transfer. The following function does the work of verifying whether timeout w...
