This question is about HAL_SPI_TransmitReceive.If a slave starts sending 8 bytes of data after the 4th byte sent by the master, is it possible to use HAL_SPI_TransmitReceive without a dummy (ignore) buffer?We will be the master side.Our assumption is...
Hi,I use STM32U575.The STM32U575 works as a USB CDC ACM device and I implemented it in standalone mode.OTG_FS_IRQHandler is called when data is received from the host device.Is there a way to determine that when OTG_FS_IRQHandler is called, it is due...
Posted on July 28, 2016 at 07:53Hi,We are developing a display using STM32F439NIH6 Microcontroller in our design. We have the following technical queries:We have referred to your evaluation board design and we are interfacing STM32F439NIH6 with SDR...
Hi there! I was hoping that the H5 series would be like a faster U5 series but instead they seem to be very cut down in terms of features. i.e. the H5 looks like a faster crippled U5.The U5 has graphics accelleration and HS USB but the H5 has neither...
* In the reference manual RM0503 rev2, in §5.4.4 (description of RCC_PLLCFGR), the description of PLLR[2:0] indicates:Caution: The software must set this bitfield so as not to exceed 54 MHz on this clock.* In the reference manual RM0503 rev2, in §5.2...
Hi all,i am using STM32C011F4U6 and i want communication between Uart1 _baud rate -115200 _8N1 and Uart2_Baud rate _4800_7E1.But STM32C0 haven't 7 bit communication option. How can i do this?Thank you
I'm designing a unipolar sine wave inverter using a lookup table to generate PWM signals, but I'm encountering some issues and have a few questions:Should the values in the lookup table start from zero, or from the peak value of the sine wave?Is it s...
Hello I'm currently trying to change the classic CAN into FDCAN, but when i try to change the clock source of FDCAN (which is PLL1Q) from 50Mhz to 80Mhz to use FDCAN, the clock configuration keeps giving the message "wrong parameter values" when i tr...
I am using the DMA to transfer data from UART 1 (Channel 2) and UART 2 (Channel 4). Every once and awhile the data seen on UART 2 which has a lower DMA priority will be "corrupted" by the UART 1 data. I know this because when I disable UART 1 routine...
I have a custom board that I need update by USB. I have a jumper that allows setting the following:nboot bit set to 1BOOT_0 pin set to 1. Then I power on the board and I can see the stm32 bootloader device on my windows machine. First I get a similar...
