Hello, I am using STM32L475 board and trying to communicate with VNF1048F by SPI. The communication protocol which is used is defined as ST-SPI. On STM32 I can configure at maximum 16 bit communication but the device (VNF1048F) requires 32-bit frame...
I have to read a 20-bit SSI signal. I connected it to a SPI interface as a “Receive Only Slave”.It appears that the SPI interface is limited to 16-bits.We could live with the first 16-bits of a 20-bit word. Can the SPI receiver do that?
Hello,I am considering the STM32H7 for a new project I'm working on.I'd like to configure the MCU to output 10 audio channels at 96khz using TDM, all synchronized. Some variants of the STM32H7 come with up to 4x SAI peripherals and support TDM.I'd li...
I designed a board using a STM32L031F6P6 about 4 years ago, (April 2021). The design has been using the internal oscillator running at 16Mhz perfectly for years. Then this past summer all of a sudden the RS232 Uart stopped receiving data until I...
Hello!I am writing a driver for the mt6701ct rotary magnetic encoder, using cubeIDE and an stm32f405 MCU. This sensor communicates via SSI, which is to say that it's read-only (MISO-only; there is no physical connection to MOSI). Using a simple polli...
I want to generate 6 PWMs using channel 1 of timers 1,8,2,3,4,5. All of them are set the same way except ARR, PSC and CCR1 registers. However, it turned out that timers 2 and 3 don't have PWM signal on their pins. The content of registers for those t...
Good evening....I would like to do an A/D conversion on Channel 9 and Channel 10. I have a timer that goes off every second and within this ISR I call HAL_ADC_Start_IT. The ISR gets called upon conversion complete. Now the question is End of Conve...
In HAL_DACEx_ClearConfigAutonomousMode(), a test is surrounded by parentheses that are clearly unnecessary in code generated by STM32CubeMx.This is not very important... but it generates warnings that I check at each compilation...
Is it possible to program the MCU via Serial using the USART pins (PB6,PB7)????
As discussed in here, im trying to use ST\s ROM bootloader, when i read AN2606 Page 280 shows the FDCAN1 rx and tx Pins Those pins dont exist in stm32H743ZI@KDJEM.1 proposed "you can activate the FDCAN bootloader with only by PH13/PH14 pins." What ...
