I have a use case for communicating with the SDRAM chip onboard the STM32G474E-EVAL1 board. Took a look at the board schematic https://www.st.com/resource/en/schematic_pack/mb1397-g474e-b04_schematic.pdf and an example project that came with the STM...
I am trying to use the HRTIM peripheral on the STM32Hh753VI as a PWM generator with variable duty cycle. I want to use Timer B1 on pin PC8.Firstly, I tried using Simple HAL functions:HAL_HRTIM_SimplePWMStart(&hhrtim, HRTIM_TIMERINDEX_TIMER_B, HRTIM_O...
I'm using a STM32H745 and running a bootloader on the CM4. In the bootloader I want to set the boot address of the CM7 using the user option bytes. Is this possible and if so, how should I do this?Kind regards
I have an STM32H563 communicating on I2C4 @ 1 MHz (fast-mode plus) to an I/O expander with no problem. However when I add a temp sensor (TI TMP175) to the same bus, communication doesn't work for the TMP175. The TMP175 communicates > 400 KHz only if ...
I am trying to set alarm canitnously in loop every 4min.But it is working only 5 time.Is there any way to set alarm cantinously after every 4 min.
Hello everyone, I'm currently doing some experiments with CAN communication with the STM32F302RB Nucleo board. The board is connected to a wcmcu-230 CAN transceiver which is connected to a Raspberry pi with a CAN header connected to it. The bus is te...
Hi,Im currently trying to set up a project where Freertos controls a webserver via lwip.I tried following these tutorials/guides and managed to be able to ping the board but not get it to host the webserver.https://github.com/MayaPosch/FreeRTOS_HTTP_...
Hello.I have developed a module that has an STM32F103ZE controller. This controller has a USB interface.In order to test the modules, this USB interface is to be connected to a Windows PC via a needle bed. Then various test commands are to be sent vi...
Hello I'm developing a self-powered device with "fast charge" feature, which assumes that USB VBUS pin can supply up to 20V. In this case, a simple voltage divider will not be able to provide an acceptable logic level within the range of 5–20 V. Addi...
i want to add some work on food_recognize.c in fp_AI_VISION ,I want to use CN9 analog to control some leds but it doesn't work in first place. I can't control those pins with writegipo.so far i only see A0 always on and A1-A5 always off. On the same ...
