Hello,I am working on a custom mixed communication implementation using USART in single-wire half-duplex mode with TX-only operation, level inversion, and interrupt-driven transmission on an STM32G0B0 (RETx package).During testing, I observed the fol...
Hello, I wrote a program to test the CAN bus.In its current version, I am using standard CAN at 1 Mb with 8-byte frames.I transmit 16 frames with a 5 ms delay between each transmission.To identify the last frame in the block, I send a frame with a ze...
Dear STMicroelectronics Support Team,I am currently working on a project that uses the STM32F091CBU6 microcontroller. Could you please confirm the current lifecycle status of this part and provide any available information regarding its projected End...
Hi, I am using STM32U083 for one of our project. We are using the I2C peripheral to communicate with NFC dynamic tag through I2C.In STM32U0 datasheet I found that the I2C pins SCL and SDA are 5V tolerent pins.We need the I2C to work independently of ...
I’m working with the STM32U575 and I found in the datasheet that the Flash programming time for a 128-bit (16-byte) write is:118 µs in normal mode48 µs in burst mode(From Table 86: Flash memory characteristics)Before finalizing our design, I need cla...
Heyho,question about FDCAN and repeating / timed transmission of the same messages:(this is neither about TT CAN nor auto re-transmission, but e.g. for messages which need to be sent every 100 ms repeatedly and "manually")After the first setting of t...
Hello people,I have been developing a firmware to be used in the stm32g051. One of the features is the ability to respon to request to get information from the uC. I used dma for the uart1 tx and rx. I was happily developing and testing the new feat...
Hello everyone!I'm facing a problem when trying to switch a bank on STM32H745 MCU. The issue happens only when the debugger is disconnected. Our implementation uses the HAL library to perform Bank switch like this:HAL_FLASH_Unlock(); HAL_FLAS...
Hello,we have to use the STM32H573 in the 80 Pin WLCSP with temperature Range 3 (to 125°C). So STM32H573MIY3Q was chosen. Due to a mistake we didn't recognized that the internal LDO can't be used. Now we have no space for placing additional component...
I am working with the Nucleo-STM32F753ZI board and using the internal OPAMP peripheral. The supply is 3.3 V, and according to the datasheet the OPAMP output should swing close to the rails, but in my case the maximum output I can get is only around 2...
