I had a board that I was debugging, and all was going swimmingly. Then I started getting an 'unable to connect' message while debugging. I didn't touch the hardware, nothing had changed. So I thought.To make a long story short, I had enabled the f...
Hi, I want to send a sequence of data on a 16 GPIO bus with a linked-node MDMA setup. How do I set the transfer frequency? I have set up LPTIM1 to have the required clock, but I can't find a way to force the MDMA to have this clock control the output...
All,I am getting an issue when attempting to write to the SD card using a DMA burst transfer. I am transferring bytes to words in burst sizes of 16 beats to 4 beats respectively. I am using the full FIFO and direct mode is disabled. Memory is increm...
Hello,I am having issues with using the DMA to transfer SD card data to RAM. This may have to do with my configuration settings, because the FIFO error register is automatically set when I configure the SD card DPSM (not when I enable the DMA configu...
Hi all, I’m run a project that use printf with: Eclipse IDE for C/C++ Developers Version: Neon.3 Release (4.6.3) Build id: 20170314-1500If I add -u _printf_float to linker flags I’ve error from compiler:Invoking: MCU GCC Linker arm-none-eabi-gcc -mcp...
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 ...
