HiI'm trying to transmit 4 16-bit words via SPI as slave using interrupts and HAL.I'm using STM32F107VCT6So I specified a buffer:uint16_t buf[] = {0x000F, 0x00F0, 0x0F00, 0x0004};And started to transmit in main:MX_SPI2_Init(); HAL_SPI_Transmit_IT(&hs...
suppose timer2 has 4 channels , i want to use channel1 as input capture mode and channel2 as output compare mode. is it possible?? please help me!!!!
Dear all, I am using SAI in STM32H7 to control an external audio codec. Everything works fine except the fact that when I look at the actual sampling frequency (SAI FS signal ) I measure 45.5kHz rather than 44.1kHz as specified in the init. The clock...
I have few question about DMA.1)Is that callback function need to be register?2)During the memory copied the source to the destination using DMA is that necessary need include the callback function?CH
I am in need of an updated REACH declaration for the product: STM32F031C4T6TR The one stated on your material declaration declares conformity to a REACH SVHC list from 2018. Newest REACH SVHC list is from January 2020BrSimon
Hi all,I searched the forum for my specific problem, but i did not find any solution for this weird occurrence. On my STM32F103 i run the RTC, which is working fine, as long as it is connected to the USB power. I store the date on 2 backup registers,...
Hi all, i want to ask about except from the reference manual where can i find out more question about the memory to memory DMA transfer.I want to figure out is there trade-off for memory to memory DMA transfer when the data size is big and small?Rega...
Hi, My self sai. Am working on stm32f745vg controller . In my application am transmitting 7byte data through uart.Sometimes entire uart transmission is blocking and untill power off my system is not responding to any command.Can i know why uart i...
In the STM32G030/070 datasheets, TS_CAL2 is missing.However, as @Andreas Bolsch pointed out in this thread, RM0454 for the G0x0 (!) explicitly refers to TS_CAL1 *AND* TS_CAL2 values from DS, and the formula given in the RM makes no sense at all wit...
