Dear all,I just found out that the CubeL4 function HAL_RCC_OscConfig() does not reset the HSEON bit (in the RCC, CR-register) in case that the HSE does not start and the function creates a timeout.I am just facing an issue where the HSE-crystal does ...
I'm trying to interface a L0538 Discovery board to a simple TTL-to-RS232 converter board that uses a MAX3232 IC (off-the-shelf from Amazon). I have VCC, GND and TX/RX from the Discovery board (UART1) wired to the converter board. I used Cube to set u...
Hi All, Looking at the STM32H7 Ref manual it seems the DMAMUX would allow for a DMA channel to be synchronized with an external event on the EXTI0 input.I would like to use this capability to trigger an SPI transmission to an ADC (since this would al...
I have this issue:I have set the RF wake up clock selection to HSE /1024 and I cannot get a BLE connection to hold.Why is that? Any other configuration might be affecting that? PeriphClkInitStruct.RFWakeUpClockSelection = RCC_RFWKPCLKSOURCE_HSE_DIV10...
Hello,I'm trying to read the pulse counter with a timer on STM32H747. The counter produces pulses up to 100KHz on one timer channel and high \ low signal to define the direction.I tried two approaches.Reference manual says, as I understand, that such...
My SPI gets stuck (waiting for RX register not empy flag, <SPI1->SR & 1> that never arrives). The operation is written with registers, not HAL.BUT! it only gets stuck after a fixed number of successful repeated operations, all the same, inside a loo...
I want to make 3 pwm with the timer1 on an stm32f103c8t6 and when the timer reaches its reset value an interrupt should be generated. I tried a lot but nothing worked. Can someone please tell me how I do this?
HiSTM32H7A3VG is one of the few stm32's who fit my requirements. This is however sold out on most platforms. Can some one comment on that? Is this chip still in production at all?
I wrote the below assembly macro in startup.S file..macro DEBUG_ToggleLED88 /*Enable clock to the Peripheral Set the pin to output Toggle PD14 */ .equ RCC_BASE, 0x58024400 .equ GPIOD_BASE,0x58020C00 .equ AHB4ENR_OFFSET,0x0E0 .equ RCC_AHB4...
Hi!To give some background, I am trying to interface SDIO over the STM32F429I-DISC1 board by configuring the pinouts to enable SDIO 4-bit Wide Bus and then connecting it to a SDIO breakout board.In the reference manual I checked the clock configurati...
