I am having great difficulties getting an SPI interface to work on a STM32433 device. I’ve gone back to the ST Nucleo dev board and used STMCube to generate a project and I am able to reproduce all my problems with only the dev board.I am using SPI1 ...
Hi at all. My question: in STM32 microcontroller, why some pins are 5V tolerant and other no? Why I/O pins usable in general purpose config cannot be all 5V tolerant?Thanks
Below is the ST sample code. /* NOR device configuration */ NOR_Timing.AddressSetupTime = 1; NOR_Timing.AddressHoldTime = 1; NOR_Timing.DataSetupTime = 6; NOR_Timing.BusTurnAroundDuration = 0; NOR_Timing.CLKDivision = 2; NOR_Timing.DataLatency = 2; N...
Question: What function could be used/ written to receive the data (URM07)?Currently, integrating an URM07 ultrasonic sensor on STM32f1xx, according to the datasheet the transmission, have tried the function on UART (HAL_UART_RxCpltCallback) to recei...
We are working with a SPBTLE-1S as a network module connected by a SPI port with a STM32L072 as a host. We would like to store the pairing data of several devices, close the connection and make individual connection with every devices. We would like ...
Hi,I'm trying to transmit/receive data by uart. I have a state machine that is processing incoming bytes periodically, so I use a ringbuffer and write every received byte into this buffer.void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart){ if (...
I want to measure a moving average of the amplitude of a fix frequency, fixed dutycyle PWM signal with slowly varying amplitude but in a noisy environment (DC motors).I want to use as little as possible CPU power to do this and have the ADC do this f...
Hello to everyone. I am currently developing a project using STM32F750N8 and W25Q128. As you can guess, the project has an LCD. So the project is too big to fit into the internal memory. That's why I need an external memory integrated programming. I ...
Hi everyone, first of all, sorry for my english, and I don't know if i should post this here, so i'm sorry if not.I have a problem when i connect the B-L475E-IOT01A board to the pc. It shows me a error message: "error, not recogniced device connected...
