I am working on controlling of a stepper motor with STM32F446 and want to generate a PWM with variable frequency (trapezoidal) and stop it after some specified (n) pulses. I want to do this with register programming not HAL functions. So I want to kn...
There doesn't seem to be any documentation on whether the optional battery holder CN15 can be used on the unit, nor what it's specs should be if it is populated with a battery. I need constant RTC backup from the time the unit is first configured.
Hello I ask to help check if all right with my code, this is my first SPI...I have use ADC1247 and seems it alive and responce for me by some of data, but ADC is sending something like "I see some of load" or "I dont see nothing". This is for 4 wire ...
Hi everyone,I recently revamped a product with a STM32F427 with a new STM32H745. Both cards have an external RAM of 16Mbyte. In the STM32F4 the data bus is 16bit width while in the SRM32H7 the data but is 32bit width. Both cards are set to go to the ...
In the ancient times, RM0316 used to contain also 'F302, but that changed long ago. Yet some relics remained, causing confusion: and a couple of more, related to these two, easily found by textual search.JW
I have configured Octospi for Single SPI mode in CubeMX and am attempting to use HAL_OSPI_Transmit() to write 48 bits to my device (as I would using a basic SPI peripheral). But the code fails. The OSPI is in the HAL_OSPI_STATE_READY mode, but needs ...
Hi allI'm using a Nucleo U575 board for reading a GNSS module. I configured the USART2 port with DMA (in circular mode, port 0 as it's peripheral to memory), Request is USART2_RX, Interrupts for USART2 and GPDMA1 are enabled and it works just fine. I...
Hello all,I am trying to read temperature with the G030. At the moment there is quite a large difference between actual temperature and temperature read by the MCU (true temperature around 23.5 degC while MCU reads 32 degC)ADC_Init code:static void A...
