Hi, I'm attempting to use UART3 on a STM32L431CC to transmit 9 bit data, I've created the following code after reading https://community.st.com/t5/stm32-mcus-products/9-bit-uart-transmission-stm32-cubemx-hal-driver/m-p/327138 With the code below I a...
There is a description in the errata(STM32G0B0CE/KE/RE/VE device errata) as shown below, but could you please provide a waveform diagram to show which part of the glitch is dangerous? USART2.10.1 Data corruption due to noisy receive lineDescriptionIn...
Hai All, We can configure a GPIO pin either as a Push-Pull or Open-drain configuration. Can anybody explain briefly, what are the applications of Open Drain configuration?
Hi all Thanks in advance.Can some one help me to select an stm32 chip which have 4 PWM channels , 4 analog out and in 3X3 qfn package? I attached a sample product. Kindly help me to select some more similar products.
To implement a "bridge" devise between two independent CAN buses, the STM32F105R8 chip was chosen. From the specifications it follows that it has 2 CAN buses, but going deeper into it I realized that they share a lot of resources among themselves.cou...
Hello,I am dealing with fixed-point arithmetic calculations on STM32G0.To avoid integer overflow risks I have scaled properly all the values involved in calculations, but a mistake can be always possible...On Texas Instruments DSPs, I have the possib...
Hi,I've ran into an issue which is about start address of an application. I'm using an own bootloader to switch between two different applications. For the application I changed the start address in FLASH.id file to 0x08040000. That works perfectly f...
Posted on August 14, 2012 at 19:43Hi All, Has anyone had problems with corrupting their flash programming when power cycling their STM32F4xx board? (or any other STM32 board for that matter) I'm able to use the boot-loader to successfully flash co...
Hello: This is weird problem. We have a STM32L496 system that handles multiple I2C devices through its three I2C buses. The I2C#1 (1MHz) has 10 NXP devices, #2 (400kHz) has 4 TI TMP117 chips, and #3 (400kHz) miscellaneous devices including other TI ...
I am using STM32F4 MCU in USB device MSC mode with data stored on SD card. I have also standard 16X2 LCD & Membrane keypad connected to MCU I want to make interface where once USB device is connected to laptop, the data is showed on laptop after ente...
