Hello,I wanted to add bluetooth capability to a board with STM32H745 controller. I have a USB port on the board on which I plan to connect a USB bluetooth dongle for bluetooth connectivity.Are there any Development boards and example codes available ...
Posted on December 06, 2017 at 18:06Hello,I'm using STM32cubemx and I have created a project using UART in 9-bit configuration. The code is generated and I can find the 'HAL_UART_Transmit' function but the pData parameter is a 8-bit pointer:HAL_Stat...
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...
