I have set up my FLASH_ACR to disable all caches or prefetch options, but with 5 WAIT_CYCLES. My goal is to predict when the read operations happen and how long they take in processor cycles. I provided some example code below, but my goal is to get ...
Hi,I had a difficult problem where my project would run faultlessly when started with the debugger, but would fail when the power was recycled.I thought that a peripheral was not initializing due to a delay in the power up phase. Putting HAL_Delay of...
Due to the current semiconductor shortage the microcontroller STM32H745ZIT6 is not available in the quantity of 210, so I had to buy the variant with higher temperature range. However, the data sheet says in small print that this variant does not sup...
Hello, I am trying to interface to an external ADC via SPI. I amusing the STM32Cube IDE with a Nucleo-144 STM32L552. The issue I am having is that the ADC requires an unusual number of clock pulses (18 as per data sheet - see attached screenshot). No...
I am using a STM32F407, and I would like to use DMA to receive data from USART1 and store in a buffer.HAL is not being used.USART1 is configured and is receiving the first byte of the message correctly. That is, the data shows up in USART1->DR.Here i...
I took the driver from Arduino for ADS119X and implement the HAL code for STM.When compiling, it gives me “undefined reference to `keepSetting'�?. First I tought on a code problem but after long time of trail and error, I was looking on forums. It’s ...
Hi, I want to be able to add CAN message with "HAL_CAN_AddTxMessage" from interrupt and main loop (loop maybe busy sometimes so I cant send all messages from it). I assume they can collide and override so its not safe to do it from both?What are my o...
I've been trying to configure a TIM6 to run at 48kHz, where APB1 is 108MHz, but because the APBDIV > 1, I used PSC = 449, and Period = 9:216,000,000 / ((449+1)*(9+1)) = 48,000And in my timer interrupt, I set a GPIO output pin to toggle. When I probe ...
I'm testing STM32L051C8T6 without any peripherals or extra electronics. No crystals used.After reset and first power down I get about 1.40uA. the MCU wakes up and powers down and then I get about 3uA in power down mode. After changing all kind of cod...
