Hello:Previously using CMSIS, I was able to read or read/write this accelerometer device. Using HAL, I am having some problems. To start, I am trying to read the ID register. I am writing in the address and a dummy byte. The address for the ID regist...
I am currently working on a project for a Battery Management System. For this I need to communicate with the rest of a car via CAN. However, my CAN has strange behaviour when sending messages. When I try to send a message at 4Hz (so not fast at all),...
Good morning,I have a problem with the adc converter of the microcontroller stm32L053. I am in the prototype state and am using the Discovery Board.I only have the analog AN0 pin connected to ground. When I execute the reading the converter does not ...
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...
