Resolved! STM32F405 doesn't want to enter DFU mode using USB typeC.
Congratulations. I have such a problem. I've made 1000 PCB prototypes and 30% don't want to enter DFU mode. If you try to turn the PCB back on multiple times, the part will go into DFU.I'm using a USB Type-C connector, could that be the problem? Also...
Resolved! HAL_I2S_TxCpltCallback is called only once
I'm testing whether HAL_I2S_TxCpltCallback or HAL_I2S_TxHalfCpltCallback is called properly by setting i2s to normal and periodically calling HAL_I2S_Transmit_DMA. However, HAL_I2S_TxCpltCallback or HAL_I2S_TxHalfCpltCallback is called only once and ...
Problem with ST SPI on STM32L475.
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...
STM32F205RG RTC Problem.
Greetings,I have connected external crystal of 32.768 KHz to STM32F205RG for RTC time keeping purpose. I have also enabled RTC output on pin PC13. Below is my code for RTC Initialization ...int main(void) { /* USER CODE BEGIN 1 */ /* USER CODE E...
Can a STM32L496RG read a 20-bit SSI signal with a SPI interface?
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?
STM32H7 SAI TDM output
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...
STM32 internal oscillator drift over time
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...
SSI and Circular DMA
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...
Resolved! PWM no signal on TIM2 Channel1 and TIM3 Channel 1
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...
