Hi. I have a B-L475E-IOT01A (discovery IOT node) and I would like to learn how to create BLE based solutions.I have previously worked with the Nucleo F446RE board for reading sensors and uBlox GPS feeds. so while not a C programmer, I'm not a complet...
Hi,I'm interested to know what may be happening that STlink can not find the STM32.A strange thing is that the BOOT0 pin is being used as a GPIO. This pin is actuating an opto coupler (it is connected to pin 1 of a PC817)What do I need to ensure for ...
Dear Members,I have two interrupts on my callback,how can I make a priority for them ? Thankscode :void HAL_UART_RxCpltCallback(UART_HandleTypeDef* huart) { if(huart->Instance==USART2) { GPS_CallBack(); } if(huart->Instance==USART1) { ...
Using the STM32F446RE with very good results so far including ADC1,ADC2,ADC3 DMA to SRAM arrays. ADCs and DMA (peripheral to memory) were fairly easy but the TIMER 1 and TIMER 8 PWM usage is giving me some problems in understanding how DMA and the ...
I have scope captures of the effect.
The UART driver has much code with detailed comments for the the things it can do. However, it should come with a disclaimer "No support for full-duplex" which is the most basic use-case. My application needs full-duplex for connection to a u-blox mo...
I would like to record/monitor a "3rd party" SPI bus conversation.I have a couple logic analyzers, that work fine on the bench.But i need longer term recording, and i need to do it in an environment without a PC and as small as i can get. And i am tr...
Hi, for my thesis i'd like to do an hexapod(it'll have like 14 servos) and a camera for facial recognizer. I was thinking about an arduino for the control of the robot and a pi3 for the facial recognizer, and then stm32 came to me. Will I be able to ...
I am trying to launch an ETB debug trace on the STM32F769NIH6 using a SEGGER J-Link Base via Ozone, but I get the error message "ETB not available". The SEGGER documentation implies that the STM32F7xxx supports ETB. The STM32F76xx documentation only...
Hi,we are using STM32F030C8 mcu for our application. The port pin PA3 is configured for UART2 receive operation from a RS-485 transceiver and port pin PA5 is configured as an analog input ADC_IN5 and receives signal from an potentiometer. What we obs...
