Hi!So I configured my SPI to work with DMA and with external CS. Before my main loop I set CS high, and everytime before I initialize communication on SPI with DMA i set CS low. Then, after communication is done I go to interrupt on that event and se...
Hi ST team,I want to define a new section in the ld script so I can use that for variables that have to keep their values in case of soft resets.I have made some changes in the script as follows, .noinit (NOLOAD): { . = ALIGN(4); _noinit = .; ...

HELLO EVERYONEI run my micro in IAP Mode then load other program to him with uart1 . in this program I start UART with DMA and toggle one Pin . when the circuit start working , everything work well and pin is toggle but the UART DMA send out zero. V...
Hello again. I'm having this problem with I2C with the STM32F303RE.I have this array of data I want to send via I2C to a sensor.std::uint8_t conf_bytes[2] = {0xF4, 0x03}; periph::I2C::write_data(I2C1, BME_ADDR, 2U, conf_bytes); BME_ADDR is the addr...
HiI have my own board, with STM32L053C8T6TR. And I set clock and program failed here: while (LL_RCC_HSE_IsReady ()! = 1) {};void SystemClock_Config(void) { LL_APB1_GRP1_EnableClock(LL_APB1_GRP1_PERIPH_PWR); // clock pro PWR controller LL_PW...
When use G Series MCUs to implement an quadrature encoder interface.i can't select Slave mode(Reset mode) while selected the Encoder Mode.:sad_but_relieved_face:
Hello, guys. Bought and STM32 board, tried to upload .hex file on it from ST-Link Utility, but when tried to connect board, received "No ST-LINK detected!". Checked in Device Manager - board appear as Mass Storage device(No ST-Link Debug, just storag...
Excuse me, how to gracefully and effectively change the TX pin "inversion" of usart3 during the operation of MCU program?In addition, can I ask questions in Chinese? Every question needs the cooperation of translation software. I'm afraid there will ...
Hello,we have UART based communication that cause crosstalk between RX and TX lines.It can't be fixed, so I'd like to solve it in SW.I'd like to temporarily disable/enable UART reception before/after sending on UART.I'm already putting DMA into Pause...
