I want to output a static DC value from an STM32G473 DAC, but I’m seeing the output value has a noise tone on it that changes amplitude and frequency depending on various other settings. The behavior reproduces with all other peripherals disabled. H...
We have a design based on the STM32G0B1CET6 MCU.Recently we noticed some failing parts after power on/off testing. Symptoms: software is no longer running and the SWD port is not responding. We sent the broken parts to ST for analysis. The report (C2...
We have a custom board prototype with a STM32H730VBT6 (LQFP100 package) and a SPI NOR flash memory.Sadly, this not connected to the OCTOSPIM_P1 port, but to the SPI1_NSS, SPI1_SCK, SPI1_MISO, SPI1_MISO (PA4, PA5, PA6, PB5) port (so, ony 2 data lines ...
Hello, I'm new to working with STM32 microcontrollers and coding in C. I'm trying to send data in hexadecimal format using the FDCAN bus. However, when I check my code during debugging, I notice that the transmitted data looks different from what I ...
I am used to find the CMSIS files (especially stm32f10x.h) in the same ZIP file as the STM32F10x standard peripheral library.In my legacy project, someone used the SPL V2.0.1 together with a stm32f10x.h V3.1.0.Unfortunately, the code won't compile un...
Hello all,We're having some 'strange behaviour' when interfacing our STM32F7 to a FPGA over the FMC bus. To isolate the problems, we're looking at all the control/addr/data on the FMC bus during memory transactions. We have a very good view into ev...
Hi STM32-Community,I'm currently using an STM32L4R-MCU and was trying to set it up for standby. By using LoRa, I don't want it to keep requesting an OTAA-Command to join the network, I'm trying to use the SRAM2 Retention of my MCU in Standby-Mode. Go...
Hi everyone,I'm using the STM32F4 Discovery board to communicate with DC Power Supply Programmable ODA OPM Series using RS232.Now, I can send SCPI commands to device (OUTP ON, OUTP OFF, VOLT 10,...), but when I send some query commands, I can not rec...
So,I set my DMA at circular mode ,adc at continuous mode ,but when I debug the timing to get into HAL_ADC_ConvHalfCpltCallback(),I found the buffer is already fulled,can someone tell me what's going on?
This question does not show any research effort; it is unclear or not usefulI am pretty a newbie in display control and I am struggling with my simple application. I need to calculate some numbers on my nucleo and then display them on a screen. Since...
