Resolved! STM32L4R5ZI using OCTO-SPI without flash memory?
Hi,I'm using a STM32L4R5ZI and i want to use OCTO-SPI with my own hardware. My question is, can i use the OCTO-SPI without a external flash memory to communicate from the MCU to the PC ? Up to now i tried the provided OCTO-SPI example provided by STM...
Resolved! NucleoL4R5ZI - Virtual COM PORT works and LPUART Tx(PG7) Works but Rx(PG8) Not working
Virtual COM port & LPUART Tx(PG7) Works fine, but LPUART Rx(PG8) is not working.Tried in both Int & polling mode, able to send and receive via Virtual COM port.Configuration:static struct MCU_UART_S testIf_UARTStruct ={ .TxMode = KISO_HAL_TRANSFE...
what is the source of clock for CANBUS
Hi,what is the clock source for CANBUS in STM32F767?I have referred the manual ,but still i cannot get the clear answer from it.the main reason to know the clock source is to calculate the bit timing .ThanksVimal
Resolved! How can I prevent the I2C from getting interrupted?
There's a sensor applied to the I2C as a slave. Also on this microcontroller there's a communication running on the UART-Interface in blocking mode. If the UART has to transmit a huge amount of data, it seems that the I2C (also blocking mode) can get...
stm32f103rbt6 i2c1 remap not working
i am using stm32f103rb i think i have found a bug i am trying to use i2c1 on pin port b 8 and 9 for that you have to remap i2c1 in afio mapr register i have done that but in debug session i note that the bit never get set i have attached code and deb...
Debug Cortex-M error
Hi,I want to debug a code for USART ISR Handler. The code is working fine. But If I debug, I am getting this error. I am using keil uvision.Cannot access target. shutting down debugging session.Why this error is coming. And how to over come this? I a...
Which peripherals clock need to be enabled?
For the most of the peripheral (e.g. ADC1) it is obvious, but what is withLL_APB2_GRP1_PERIPH_SYSCFG or LL_APB1_GRP1_PERIPH_PWR? Does the voltage regulator work, if PWR peripherals clock is disabled?
STM32L0x2: Combine two comparator outputs
I have a STM32L072KB microcontroller and want to combine two analog signals (they represent a kind of "quadrature encoded signal" with a 50% duty cycle) into one "combined digital output signal", which have the doubled frequency (for my purpose the d...
