The manual is unclear I believe, when the sequencer is used but DMA is not used.Relevant code is below, but in a nutshell, after configuring the sequencer and starting the ADC, I wait for EOC, read the data register, wait for EOC, read the data regis...

I am trying to use SysTick on STM32G070. Clock tree must be OK because everything else works, as far as I can tell, but when I include the following code (Keil compiler does not flag errors or warnings), in my initialization routine, interrupts stop....

I bought a $4 Aliexpress STM32G070RBT6 board. I have a program that uses various UARTs, timers, pins, etc. The CPU should be unprogrammed since the board is new. For all I know, the CPU may be counterfeit, but usually these sort of Chinese boards wor...

I created a Keil project for STM32G070 without using Cube. It compiles but the link fails with error L6236E which seems to indicate there is no startup file. Can anyone send me a file that will work? In case it matters, the board that I am using is a...

void USART3_IRQHandler(void) is incorrect, since USARTs 3/4 share the interrupt, it doesn't compile. What replaces 'USART3' in the interrupt handler?NVIC_ClearPendingIRQ(USART3_IRQn); is incorrect since USART3 3/4 share the interrupt. What replaces '...

Thanks for your help. Interrupts are disabled during data collection. I have also discovered the WAIT feature that should help to ensure that overruns don't occur.

Thanks to both of you. Your relies seem to be different, and no wonder since I have chosen an unusual technique for collecting data. To be safe and meet everybody's requirements, I have modified the code as shown below. Please remember that this code...

How can I find out which HAL functions use SysTick, so that I can avoid them? SysTick amongst all the G0 timers, is 24 bit, allowing me to time events down to 1/8 usec over a complete 1 second loop time. And while I am complaining, I wish Arm had the...

I think I found the answer. My code uses HAL_Delay() which probably uses the SysTick interrupt, which I disabled in the snippet in my original post. As everyone is aware, calls to HALxxxx are everywhere in STM32 code, so other mysterious failure may ...

I haven't used the ST-Link gadget shown in pic for 10 years, so I'm back to being a newbie.Connected 3.3V, SWCLK, SWDIO, GND. but not BOOT0. Keil says need to upgrade, when I say yes then msg about not in DFU mode.. If refuse upgrade, Keil says "comm...
