Hi.I have in my hand Nucleo with STM32F103 (old uC but to understand grouping newer is not needed).In Programming Manual PM0056 on page 134 and 135 I can see a SC_AIRCR register which on PRIGROUP field at reset are all zeros, but on next page in tabl...
Hello,I am trying to update some code to use UART with DMA for receiving instead of the polling method.I want the implementation to work for messages of unknown length so I use the HAL_UARTEx_ReceiveToIdle_DMA function.I know that the maximum message...
Hello.STM32G070CI'm having some issues with the WUF flag when exiting Standby. Exit mode is set to WKUP1 (PA0).I poll the register after exiting standby and in the PWR->SR1 register, the SBF flag is set, but the WUF1 flag is cleared.I also noticed an...
Tip me please why after migration from STM32U575ZIT6Q (evaluation board STM32U5 Nucleo-144) to STM32U575RGT6 (user board) with the same configuration and project code I have problems:FD-CAN works up to 2Mbit/s instead 2.5MFlash programming a fault (t...
I was using HAL_UARTEx_ReceiveToIdle_IT to receive data on modbus. After running for couple minutes without any issues it hits the HardFault_Handler. My registers at the time of HardFualtany help would be much appreciated
I have two input channels which I have to sample simultaneously so I wanted to know what should be the ioc setting for the same? and what HAL commands are used to run ADCs in this mode?
I see that you guys are offering free samples for the new C0 chips. Are these only available for business or can hobbyist have access to these samples? I am working on some home automation devices and would like to try these chips as I am familiar wi...
There is no firmware in the µC! I expected all I/Os to be floating. Some are floating. But PB13 seems to be pull-down is activated. I did not find the reason in data sheet or Reference Manual. What Pins are safe floating after reset?
Hi, I am using STM32G030K6T6 Microcontroller. I need a help for how can i Enable TDR Register and handle the interrupt handler. interrupt handler does not run and I need is Five Bytes data transmit in Uart_DMA. But registers does not wrk properly. I ...
