When exactly does SPI TXE get set in an F730

I am trying to change from using a Timer PWM controlled outgoing bit stream to an SPI controlled outgoing bit stream. It would be very nice to output a 32-bit word in one shot using the 4-byte FIFO at each TXE interrupt, but the RM seems to indicat...

Resolved! STM32H757-EVAL doesn't work at FDCAN_MODE_NORMAL

Hello everyone, I am working on our project based on STM32H757I-EVAL board (or NUCLEO-H755ZI-Q). I have already tested several parts that we expect to use Ethernet, UART, I2C, IOs, LCD, LEDs, etc. I have troubles with LwIP TCP/IP stack and finally I ...

STM32L151. Does the CPU halt during EEPROM write?

I'm using an STM32L151 and I write values to EEPROM. I have a timer interrupt that executes at 1000Hz. But I see that the interrupt lags when I write to EEPROM.How can I avoid this? Should I place my timer interrupt handler in RAM? Would that work?

Resolved! TIM1+DMA Driven GPIO transmit speed limit

I am using STM32F407ZGT6 and configured the TIM1_CH1 to trigger DMA2 to transmit data through GPIO. Since the protocol is using both raising and failing edges, I need to control both data pins and the clock pin. So the TIM1 is just generating PWM sig...

Resolved! How can UART_Tx impact neighboring GPIO pins?

I have a STM32G071 where, among other stuff, an UART interface an a GPIO input are configured. UART is mapped to PA9 - PA12 (Tx, Rx, CTS, RTS). PA8 is configured as GPIO input mode (no pull-up, pull-down). On the net connected to PA8 is a hall sensor...
