Hello, I am trying to write something on the I2C bus to a digital potineometer using the STM32F469I-DISCO board but I get no result, even no response from the device and its like there is no device connected on the bus. I tried the same potineometer ...
Hi, I have a pin labeled "DISABLE_HV" that I want switch between open drain and ground (and vice versa) to switch-off and switch-on a DC-DC converter. How can I implement this functionality in the code using HAL library?
Hi, I'm using on a STM32L4R9 a LPTimer1 in interrupt mode. If i use it with the PCLK1, HSI or LSI as clocksource it works as expected. It counts to the ARR value and then the interrupt occours. If i use the LSE as clocksource the LPTimer seems only t...
I am trying to set up the on-board 512Mb AP PSRAM to have a 1K word linear read burst.Similar to the HSPI demo in the BSP example, I call the function "BSP_HSPI_RAM_Config16BitsOctalRAM(...)"with my configuration set to use a 1K word linear burst.How...
Hi.I'am develop an aplicaction on NUCLEO-L433RC-P board, we want to implement FreeRTOS with low power modes (tickless STOP modes) to to have the lowest possible energy consumption.I followed all the steps in your YOUTUBE video: FreeRTOS on STM32 v2 -...
Hi everyone, I checked but I couldn't find anything. Is there any application or demo project for ISOBUS communication on STM32 or demo boards? Thanks,Erdem
Hi All,I have written a baremetal program for CAN Tx and Rx for the board STM32f103C8T6.The normal tx and rx function are working fine , next i have to simulate errors to see how the can system i have written works/performs.I have some ideas but am n...
I am about to release firmware to production and would like to include the proper options bits in the firmware so that production can simply program the .elf file at the same time as updating the option bits. I realize that there are several option ...
Hello, sorry if this question is in the wrong topic, first post on the STM community.So i'm working with a solution for updating the firmware on a STM32 M7 microcontroller (NUCLEO-F756ZG). I found a project on Github (ESP32-Musings/OTA_update_STM32_u...
Hi,We have build a custom board based on the STM32L4R9I-EVAL, On our board we also used PSRAM IS66WVH8M8ALL-100We are facing a problems using this PSRAM and we saw in the following forum discussions that it's a known issue and that the STM32L4R9 Doe...
