Hello,I am using for the first time the FDCAN peripheral. I have configured it in classic CAN 2.0 mode and I have problems with transmission.In particular, when I start a transmission, nothing is output on the tx pin, and the TRP field in the FDCAN_T...
Hello, I am developing an application, starting from stm32 empty project.The main file presents the following preprocessor header, that triggers the reported FPU initialization warning when I try to build the project. #if !defined(__SOFT_FP__) && de...
I'm encountering an issue while attempting to configure my STM3240G-EVAL board to function as a “Mass Storage Device” with a microSD as Storage.I used the MX configurator and followed tutorials but encountered the same issue every time. I can compile...
Hi,I could use some help getting started with SPI5 (limited feature set). I want to operate as SPI master and send a single byte. I want to control SS manually as ordinary GPIO out.I've enabled the peripheral clock, and I can see in the debugger that...
Hey, I am trying to send 20 messages over FDCAN using the G0B1RE Nucleo board. The problem is that only a few messages arrive (~12 most of the time), the messages have wrong data and sometimes it crashes the FDCAN-Module. When it crashes the HAL_FDCA...
Posted on September 01, 2017 at 06:37Hi, I have an STM32F746G-DISCO board and I am running some DAC examples. I need physical access to PA4 (DAC_OUT1) and PA5 (DAC_OUT2) so I can display them both on the oscilloscope. The DAC example says you can a...
I am using STM32CubeIDE 1.15.0, writing code in C, including some assembler code, for the STM32G431.According to ST's programming manual PM0214 in Section 3.5.1, I should be allowed to useadc r0, r1, lsl #1However, gcc barfs (I am using standard gnu1...
Hi all,I am in the process of bringing up a prototype board with a STM32L4R7ZIT6 up. I'm using one DAC channel via the opamp. This is working all right, until I designate the default output of the DAC to another function e.g. dig output. The DAC is c...
- STM32G0B0RE Our controller was running fairly well but on occasion we were seeing the windowed watchdog trip(The IWDDGRSTF flag set on reboot.) We were not sure whether this was a too short or too long trip so decided to extend the window wider...
HiThe DataSheet doesn"t give the input impedance of internal OP-AMP in follower mode.The only value is for PGA mode.There is a similar question about STM32U575 on the forum but not answer... Thanks for your help have a good day. Aurélien
