Posted on April 03, 2018 at 08:25Hi. I'm testing a new board with a STM32F091rctx micro, where the 485 bus is bring up using these pinouts:PB5 (Enable)PD2 (Rx)PC12 (Tx)Is the Enable signal moved by the Hal libraries or have I to move it?Using an osc...
Posted on April 03, 2018 at 08:43I want to ask about RCC registers. Can I change the divider values PLLMUL and HPRE in Runtime?The program code is then executed to reduce the frequency (decrease in consumption), then increasing the frequency and ex...
Posted on April 03, 2018 at 08:57Hi,I am working on STM32F769NI-disc1 board. I am trying to get the triple ADC regular simultaneous mode to work with DMA. I have generated the code using the stmcubemx and with little understanding from the different...
Posted on April 03, 2018 at 08:07I am wondering if the timings are set correctly in CubeMx for the LTCD Configuration for the F746G-Discovery board. I find that if I run with the default settings in CubeMx for this board the display often is very n...
Posted on April 03, 2018 at 04:33 I use CubeMX to make a OTG FS VCP, seems OK, data can transmit and receive, but there is a problem, PC software send a command to MCU, and I stop PC program, command keep received in MCU. I set a break point ...
Posted on April 02, 2018 at 22:28HIIn I-CUBE-LRWAN it says that it is very easy to port to others mcu.Do anyone have a description how to setup a new MCU exsample STM32F303CCT6 ?1 . If i make a cubemx project ..Which file to copy to the project an...
Posted on March 12, 2018 at 16:31Hi, I am having a problem using COMP1 on a STM32l496 chip. I am doing a proof of concept on a Nucleo board. I'm using a signal generator to put a 1KHz sine wave on the IN+ pin, and I'm using the DAC as the IN- s...
Posted on March 31, 2018 at 00:35I am trying to construct a CubeMX based version of the LwIP_HTTP_Server_Netconn_RTOS project in the repository. I have used the board selector in CubeMx of the H743i-Eval and setup the options for the hardware to ma...
Posted on June 08, 2017 at 17:31 Edit: OK so just for the record, I guess, I replaced HAL_I2C_Master_Transmit_DMA() with HAL_I2C_Mem_Write(), which seems to be the appropriate command for what I'm doing, and that is working fine. One questi...
Posted on April 01, 2018 at 17:04I have a PCB made for 100 pin F407. Is there a STM32F6 series CPU which works in that PCB? There seems to be a lot of 100 pin F6 CPUs. Is there something I should know, especially if I make a new PCB fit for both.#st...
