Posted on June 01, 2017 at 11:40Hi St Community,I’m working on CAN J1939 protocol, with two STM32 F103RB - Nucleo64 and two transceivers (MCP2551). I’m looking for decrease the data rate to 250 Kbits/s but I have no idea of how to do that. Shoul...
Posted on June 01, 2017 at 07:51Hi all,I am using stm32f030RC controller,for my application need to print the float values on the hyperterminal.Printf is working fine for text,charters & interger values.i am using stm32cubemx generated code & atolli...
Posted on June 01, 2017 at 13:45Hi all:I wonder how UART error handling works when using DMA on an STM32F4xx, although I do use STM32F0xx microcontrollers too.If a parity or frame error pops up, what is the best way to handle it? I guess you cannot ...
Posted on May 30, 2017 at 20:54So, a stm32 Nucleo (little sticker indicates -F411RE) was left on my desk. I looked at tools and got System Workbench installed. I figured a first test (of myself, the board, and the tools) would be to modify LED bli...
Posted on October 26, 2016 at 08:45Hello experts, when compared the block diagrams of STM32F7 and STM32H7, STM32H7 seems to have no ART accelarator. Cannot software access to the internal Flash without any wait cycles? Best regards, Yasuhiko Koumoto...
Posted on May 31, 2017 at 08:37I want to set Non maskable (NMI ) interrupt on a particular port pin (Microcontroller -STM32F207VE). I am not confirm Which port pins can be used. I am not able to figure out from datasheet and technical reference man...
Posted on May 31, 2017 at 15:46I am trying to send a large buffer of samples to an external DAC using SPI to create arbitrary waveforms. I have previously done this successfully for 8-bit data and have tried to adapt my code to work with a 16-bit da...
Posted on May 31, 2017 at 18:31Hello guys,I would like to discuss with you about the problem of uSD card.Normally, it's working well if the application executes from internal Flash, but when it runs on SDRAM, the uSD can not initializes with FR_DISK...
Posted on May 30, 2017 at 15:48HiThere are some MCUs from several microcontroller manufacturer that they have one or several Peripheral called Configurable Custom logic. by using this peripheral you can implement some glue logics design without need...
Posted on May 31, 2017 at 14:56Hello everyone, I have looked up this issue but I am afraid I have been unable to find a solution. I am trying to wake a stm32l151CCT6 MCU up from stop mode by way of USART1 interrupt. I have the RXNE interrupt enabled...
