Resolved! Using an USART in SPI master mode, which pin should be the NSS?
When using an STM32L0 USART in SPI master mode, if the Slave needs a low level at the beginning of the frame and a high after the data byte, can I use any GPIO as NSS master to output this levels?
STM32F767ZI USART abnormal Rx in interrupt mode
I do my code with CUBEMX 5.6.0 with en.STM32Cube_FW_F7_V1.16.0 & Atollic 9.2.0.My trouble : when i send a data by USART3 (using putty or the terminal in Atollic) even if i set that i want to recive 1 byte the HAL_UART_RxCpltCallback is fired two time...
Get hardware NSS mode for SPI with DMA in STM32 (F0/F4) working? Or alternatively manually start the according DMA channel (Low Level functions)
Hello,I'm trying to get a SPI communication in between two STM32 running with DMA. One is the STM32F051R8T7 (slave), the other ist the STM32F412ZET7 (master). There is nothing else on this SPI-bus. The best would be, if it runs with hardware controll...
Resolved! STM-STUDIO-STM32 - Snapshot acquisition mode
This STM software allows to monitor and modify the value of some variables in real-time using the SWD or JTAG connection in a non-intrusive way.In the documentation for the use of this software (https://www.st.com/resource/en/user_manual/cd00291015.p...
IBIS Model Check
Hi,I am using the STM32F413ZHJ6 in a design, BGA package. I have noticed some strange behaviour in the IBIS model of the part. When modelling the output of K11 and K12 (PD14 & PD15) the capacitance for the model is in the nF range. This is very large...
Resolved! Using SysTick causes reset?
UPDATE: The issue has been solved. The nBFB2 option bit had to be enabled.Hello, I am currently programming and STM32L152RE on a Nucleo development board. I am using SysTick as a .5s timer that ran a status LED. Everything was working up until recent...
HAL CAN module using BxCAN fails to initialize when RXD and TXD aren't physically connected.
Hi all, I'm using STM32L476 and I am using its BxCAN with a transceiver TJA1042. I have the transceiver's RXD to STM32's CAN_RD1, and TXD to CAN_TX1. Both pins on STM32 are set to be pulled up. And the transceiver does have a 3.3V reference. There's ...
Controlling with ad9833 signal generator stm32f4
Can you share a sample project that controls the ad9833 module with the stm32f4 board?
Resolved! Read Parallel display commands with STM32
Hi, is it possible to connect STM32 instead of display and read its pins (A0, RD, WR, D0, D1, D2, D3, D4, D5, D6, D7) to know what device is sending and maybe replace original display with different display?For example I would need to detect that WR ...
