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...
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 ...
Hi,I have been working on my Custom STM32F405 Board. I have been using different Communication protocols like I2C,SPI2,I2C1,USB OTG on the same chip in a single code using FREE RTOS.However, I have a problem with SPI1 of STM32F405. I'm trying to com...
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?
Hi,Connect a 32-bit PSRAM to FMC bank 1.For single WRITE ACCESS, I understand that FMC D [31: 0] and FMC NBL [3:1] are determined by the AIX data size and bit1 and bit0 of the Memory map address, is that correct?PSRAM WRITE ACCESS (single transfer)...
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...
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...
1.Assembly language2.C language without HAL3.C language with HALAnd why you choose that method ?
The documentation for the DAC says "A DMA request can be generated when an external trigger (but not a software trigger) occurs if DMA requests are enabled"But I want to configure the DAC to have no trigger, and instead use TIM12_TRGO to drive the DA...
