Posted on September 14, 2017 at 13:55My question is regarding RS485 Modbus protocol I am using STM32F030 Nucleo board for communication with RS485 board two USART is used (USART1 AND usart2) for communication purpose I am sending data USART2 (ST-KIT...
Posted on September 14, 2017 at 11:35Hello,I try to use Usart Tx with DMA on a STM32L052K6, in order to send a string without needing to send each character independently. I don't use ISR. The Usart TX works well without DMA using HAL functions.The ...

Posted on September 13, 2017 at 09:15I want to know if we have pin to pin replacement for #STM32F407VGT6 with higher RAM and Flash memory. #STM32F407VGT6 has 1MB of flash and 192 KB RAM but we are running out of space in both areas and hence looking...
Posted on September 14, 2017 at 10:55I want to connect NUCLEO-L031K6 with my PC by UART. I use STM32CubeMX to generate project.In the project, LPUART1 is always disable and cannot be configured.I configure USART2 to asynchronous, consequently PA2 an...
Posted on August 25, 2017 at 15:30I'm planning to use a STM32L432KC to read 18-bit transmission from an external slave device. It seems the RXONLY master mode is a perfect match for this since it is outputting a continous SPI clock. I could set the ...
Posted on September 14, 2017 at 13:59Hi, I am using ST cloud platform to log sensor data from STEVAL-IDI004v2 board. It is observed that there is a periodicity of 5 secs to log data in the cloud. Can we change the periodicity? If yes, how can i do t...

Posted on September 14, 2017 at 13:40I'm trying to use SPI DMA with FIFO to read a ADC. The working procedure of my code is as below:ADC give a interrupt to inform the data is ok to read, then we kick start the SPI DMA to read 16bits x 4 (4 half wor...
Posted on September 06, 2017 at 09:30I'm using I2s2 and I2s2ex in Full Duplex mode,set the DMA in DMA_CIRCULAR mode,but HAL_I2SEx_TxRxCpltCallback can't be called,so I modify as follows.Is this a bug?static void I2SEx_TxRxDMACplt(DMA_HandleTypeDef...
