STM32 Communication between 7E1 and 8N1
Posted on July 28, 2015 at 09:30Hi all,i am using STM32F0 and i want communication between 7E1 and 8N1.But STM32F0 haven't 7 bit communication option. How can i do this?Thank you
Triggering the DAC DMA with HRTIM
Hello,I am trying to trigger the DAC1 DMA off of the HRTIM Master channel using the hrtim_dac_trg signals on an STM32G474, but I am not getting any output on my DAC pin. The timer does seem to be running (I can see MCNTR incrementing in the debugger)...
SWO outputs only works with HSI enabled for SYSCLK, not HSE
Hi, I am using a STM32F105RC. I was trying to get SWO printf outputs to work, and found that they only work when I configure HSI (8MHz) to be used for SYSCLK, but not when I configure HSE (25MHz) for SYSCLK. I've confirmed that the external oscilla...
Glitch in SPI DMA transfer seemingly also related to USB on STM32G4
I have a project using all custom code (not HAL) in which I have two 6 byte SPI DMA transactions running periodically based on timers. It's set up so I can even pause the main CPU and these transactions will continue. I've found that in certain condi...
Resolved! I can't send AT commands
Board: STM32 NUCLEO F103RB (MB1136 C-01)Wire cable with ESP8266: UART1_tx (PA9) -> RX_ESP8266 and UART1_rx (PA10) -> TX_ESP8266Hi all,I try to send AT command between board and ESP8266, without success.I send the command but I don't see no reply. The...
Resolved! Serial Communication between STM32 High Performance MCU and Time Delay DS1023
Hello, I need to implement a serial communication between MCU such as STM32F4xx or STM32F2xx and a Time Delay DS1023 but its datasheet doesn´t mention any standard communication protocol such as SPI.Could i use three GPIOs as Serial Input, Serial Out...
QSPI external loader
I am working with QuadSpi and external Flash, I see that there is a BSP for the mt25ql512abb. Does the mt25ql512abb MCU component repository also include MT25QL128ABA? Using a stm32h750. Thanks!
Are there any solution about the CAN buffer overwriting?
I am currently working for the interface controller and it interface the two different CAN speed.But sometimes the received CAN buffer looks is overwriting with new messages under high CAN messaged load conditions.These are FDCAN1 and FDCAN2 setting ...
STM32 DMA UART Transfer Issues
I am using the DMA to transfer data from UART 1 (Channel 2) and UART 2 (Channel 4). Every once and awhile the data seen on UART 2 which has a lower DMA priority will be "corrupted" by the UART 1 data. I know this because when I disable UART 1 routine...
