Greetings,We've found several STM32 MCUs with what appear to be poorly executed laser engravings. Is there anyone I can contact to get an official opinion on these chips?We are not the firm that designed and built the boards. We are reviewing other f...
I’m using the STM32H563VI microcontroller in my project, together with an external STWD100PY watchdog connected to it. When I try to flash the microcontroller’s memory, the watchdog resets it during the programming process, causing the write to be in...
Hi, Programmed sparkfun thing plus stm32f4 i2c bus in slave mode and sending the serial data to the i2c bus. The bus is hanging after some point of time. Any help will be appreciated. Thanks,
Hi all, I am currently trying to configure the NUCLEO-F072RB to work with an EVM board from TI via SPI. I am very new at using STM32 and I am not quite sure how to go about it. 1) I have already used CubeMX to do the recommended settings. Do I also n...
I'm trying to interface DHT22 with STM32F429i but the problem is that the sensor never responds with the high signal for 80 micro seconds after the initialization. Here you can find my code, so please tell me what could be wrong, I have been debuggin...
STM32WB55 NUCLEOI have 2 ADXL362s on SPI1.They both have their own separate chip select GPIO pins.They are both configured the same.They are both in the same orientation (on the same breadboard).The output of both is processed using the same logic.On...
Hi I'm trying to drive a screen through a parallel interface. The screen has the ST7796 driver. I was able to initialize it, but it only displays noise. When data is sent through the parallel interface, it doesn't display. Do you know the necessary ...
Hi all.I want to do read/write on eeprom microwire 93c66 but there is no open source HAL library that I can find. how can I do it? I am new to stm32.Thanks
No Data Received on MCU.We have connected MAX3232 RS-232 IC on UART2 (PA2 - Tx & PA3 - Rx) of STM32F0303RCT6.When UART2 is Configured in Loopback, we are receiving the data that is being transmitted by MCU - on both MCU Loopback & MAX3232 Loopback.Bu...
Hi, I am working on configuring LoRa (E22-900M22S) and the MAX3485 transceiver to establish RS-485 communication using the STM32H753ZI. I have connected the LoRa and MAX3485 modules as per the following reference:LoRa(E22-900M22S)LoRa PinSTM32H753ZI ...
